Description

DEVICE, SYSTEM AND METHOD FOR DISPENSING A PAYLOAD

TECHNICAL FIELD

[0001] The present disclosure relates to a device, system and method for transporting and dispensing a payload from one place to another. The invention also relates to a portable temperature regulated dispenser device that can be attached to Unmanned Aerial Vehicle (UAV) and dispense a payload of living or non-living things from one place to another. The invention also related to a portable temperature regulated live insect dispenser device that can be attached to an Unmanned Aerial Vehicle (UAV) and dispense live insects that are previously kept hibernated under cold condition.

BACKGROUND

[0002] Currently, there are very few live insect dispensers that are able to release a large number of insect with a small foot print. Handling of live insects takes a lot of resources to manage and guide them into the intended direction.

[0003] Patent number US8408164B2, filed by International Flymasters Inc, discloses a system and method for release and dispersion of flies or other biological control. This prior art disclose about, a system and method of release and dispersion of genetically altered flies or other insects to control insect population. The apparatus can be carried by an aircraft and includes removable fly chambers that contain fly containment cylinders. A refrigeration system operates to physically retard the fruit flies. The flies are then released from the fly containment cylinders and fall to the bottom of the fly chamber. Gates on the bottom of the fly chamber are opened manually or remotely to allow the refrigerated flies to fall through the nesting chute into the spiral release controllers. The spiral release controllers dispense the genetically altered flies into the exit chute. The genetically altered flies travel through the exit chute, fall to the earth below and mate with the population thus serving to decrease population by capitalizing on a weakness in the reproductive cycle of the fruit fly or other insect. [0004] The prior art device has high form factor and hence carried on a large plane (Cessna Caravan Airplane with 16m wingspan and 11 .5m fuselage/ body). It uses dry ice or liquid carbon dioxide (CO2). It is generally used for dispersing sterile male fruit flies or genetically modified fruit flies that later mate with the female fruit fly, breaks the life-cycle of the fruit fly and decreases the population. Further the system requires an aircraft pilot and a plane to deliver the insect payload. It is very costly and subjected to a narrow range of weather condition. The takeoff and landing of the aircraft required a runway with an extensive aviation support system. Special mounting must be retrofitted to an aircraft. This can be expensive and cumbersome. After mounting, the aircraft will have to comply with extensive check and meet aviation standards before the aircraft is permitted to carry the payload. Further, mounting of the device is likely to take no shorter than 30 minutes.

[0005] Patent publication number WO2018140273A1 , filed by Verily Life Sciences LLC, discloses systems and methods for mobile automated mass release of insects. In one embodiment, a system includes: an insect storage device defining one or more internal compartments to store a population of insects; a loading mechanism for loading the insect storage device with a population of insects; and an insect release device coupled to the loading mechanism and configured to release into an environment one or more insects from the population of insects in the insect storage device.

[0006] Patent publication number W02017154004A1 , filed by Senecio Ltd., discloses continual aerial release from drones. A storage and release mechanism for aerial distribution and release of insects from an unmanned aerial vehicle, the release being aimed at controlling a wild insect population, the wild population having fluctuating local densities, the mechanism comprising a switch for switching between two or more different sustainable insect delivery rates for release of the insects. The method is particularly suitable for sterile male mosquitoes in programs to control wild mosquito populations.

[0007] Patent publication number WO2016088127A1 , filed by Senecio Ltd., discloses a release method for insect distribution. A diffuser for distributing insects such as mosquitoes from an aircraft, comprises a distribution tube connected to an insect source at a first end and open to the outside at a second end in a direction away from that of travel of the aircraft, for distribution of the insects; and a profile surrounding the second end, the profile being shaped to define a steadily changing airspeed. The pipe may be aligned with airflow at the point of exit of the pipe and protection may be provided around or just upstream of the exit to provide a point of minimal air velocity at the exit, the exit being the point of release of the insects.

[0008] The above prior arts requires an aircraft pilot and a plane to deliver the insect payload, due to the heavy weight of the payload. The unmanned device used in prior art W02017154004A1 , is not universal to adapt various dispenser devices and required complex or time consuming installation on UAV. Further, the device should be controlled anywhere anytime and required data of the device should be easily obtained, to know the status of the device time to time.

[0009] A need, therefore, exists for an improved portable temperature regulated dispenser device which when attached with the UAV, can transfer a payload of living and/or non-living things, especially live insects, from one place to another place, without adversely affecting the condition of the payload placed inside the device.

[0061] FIG. 1 is a block diagram of a portable dispensing system 100 for dispensing the payload from one place to another, in accordance with the disclosed embodiments. The system 100 is used for transferring the payload from one place to another. The system 100 has one or more portable dispenser device 101 used for storing the payload. A small Unmanned Aerial Vehicle (sUAV) or Unmanned Aerial Vehicle (UAV) 104 can be used to carry the payload from one place to another. A control unit 108, can be used to control the operation the portable dispenser device 101 from a remote location.

Instructions from the mobile device can be used to control the sequence of event of the device 101. Each portable dispenser device can have a unique Identity (ID) that is used by the control unit 108 to send the control signal to the respective portable dispenser device 101. [0063] In one embodiment of the invention, the system can have one or more portable dispenser device, each controlled by one or more control unit. Each portable dispenser device has a unique identify assigned to it and the control unit can send control signal to the portable dispenser device based on the unique identify.

[0064] The payload for carriage and release from the device disclosed herein can include but are not limited to live insects such as mosquitos, biologies, parenteral and seeds.

[0065] In one embodiment of the invention, the portable dispenser device 101 can be used as a portable live insect dispensing device, which temporally hibernate the live insect under cold condition during transits. After the device is moved from one location to another, the temperature of the device can be adjusted to make the insects active prior to them being dispensed out of the device.

[0066] In one embodiment of the invention, the portable dispenser device 101 can be used for carrying and transporting biomedical lifesaving biologies from one place to another. In one another embodiment of the invention, the biomedical lifesaving biologies can include but are not limited to vaccines, antibodies, anti-venom, insulin, injectable adrenaline (for critical anaphylaxis). The dimension of the chambers can be modified to fit to the size of the biologies and the condition can be maintained at low temperature between 4 to 10 degree Celsius.

[0067] In one another embodiment of the invention, the portable dispenser device 101 can be used for carrying and releasing seeds from one place to another. The chambers can be modified via the size and shape to fit the type of seeds to carry the payload. If the payload (for example, seeds) to be carried are adversely affected by heat or cold, then the cooling chamber and cooling unit can be removed.

[0068] In one another embodiment of the invention, the portable dispenser device 101 will act like an Airlifter for transporting the payload. [0069] In one aspect of the invention, the portable dispenser device 101 can comprise a payload chamber for storing the payload; a cooling chamber having at least one refrigerant material,; at least one first fan to blow air and circulate cool air inside the payload chamber; at least one second fan (heating fan) aid in dispensing out the payload from the payload chamber, when at least one door of the payload chamber and at least one door of the chamber are opened; and an electronic unit to control operation of the payload chamber, cooling chamber, the first fan, the second fan and the door of the payload chamber, wherein the electronic unit has at least one wireless communication means. The electronic unit has a micro-controller processor on printed circuit board assembly and further has a Wireless Fidelity. The portable dispenser device can further comprise a camera for capturing and sending the live video information of the portable dispenser device. The servo control system can be used to control the various operation of the portable dispenser device.

[0070] In one embodiment, the components of the portable dispenser device can be enclosed within or secured to a housing or casing made from a suitable material. In particular, the payload chamber, cooling chamber, at least one first fan, at least one second fan and electronic unit can all be enclosed within or secured to the housing or casing of the portable dispenser device. In one embodiment, the at least one second fan can be secured externally to the side of the housing or casing via air inlet duct or passageway. In one embodiment, the housing or casing can be made of insulating material to maintain the internal temperature of the device and payload chamber. In one embodiment, the housing or casing can be made from materials including but not limited to plastic, foam, aluminum or other lightweight metals and/or carbon fibre.

[0071] As will be appreciated, the housing or casing of the device can be manufactured so as to prevent unwanted or involuntary release of the payload from within the payload chamber while still permitting warm air and cool air to flow therein via the first and second fan. In one embodiment, the payload chamber can be substantially airtight with one or more one-way valves. In this regard, the vents or inlets of cool air from the first fan into the payload chamber can include a one-way valve to allow only air inside the payload chamber while substantially preventing air or the payload out in the opposite direction. Similarly, the inlet of the warm air from the second fan into the payload chamber can include a one-way valve to allow only air inside the payload chamber while substantially preventing air or the payload out in the opposite direction. The one-way valves function to prevent the passage of air and any payload therethrough with the only exit being the doors of the payload chamber when opened. Accordingly, the one-way valves can provide a dedicated flow of warm air and cool air through the payload chamber and out of the opened door.

[0072] In another embodiment, the vents or inlets of the cool air from the first fan and the inlet of the warm air from the second fan can include a netting. The netting can be configured to allow only air inside the payload chamber while preventing the payload passing out of the payload chamber through said inlets. The pore size of the netting can be adjusted dependent on the payload, for example in the instance of storing insects the pore size of the netting can vary dependent on the size of said insect.

[0073] In one embodiment, the device may include one or more containers for storing the payload separately in a sterile condition and then placed inside the payload chambers.

[0074] In one embodiment, the refrigerant material can include but is not limited to dry ice, electronic cooling plate (Peltier cooling) or other conventional cooling materials. In one embodiment, one or more refrigerant materials can be used to form a cooling unit. In one embodiment, the cooling unit can include the refrigerant material and a heat sink or heat exchanger for improved heat transfer.

[0075] In one embodiment, the portable dispenser device can include at least one cooling chamber, at least one cooling fan, at least one payload chamber, at least one door to the payload chamber, at least one air inlet duct, at least one warm air fan, a battery compartment and PCBA that house the control electronics of the devices.

[0076] As will be appreciated, the payload chamber can be divided into two or more payload chambers with each having a door at the bottom to release the payload (e.g. insects). In one embodiment, the payload chamber can include four payload chambers with four doors, each payload chamber having one door. Each payload chamber and related door can be opened at the same time or at different times. Thus, with multiple payload chambers the payload chamber doors can be independently operated and opened to release the payload in each payload chamber.

[0077] The cooling chamber can be positioned above or on top of the payload chamber, whereby the cooling fan can be positioned appropriately for the respective function of circulating cool air into the payload chamber.

[0078] The first fan can also be called as the cooling fan, as it is used to circulate the air between the payload chamber and the refrigerating material in the cooling chamber, to create a cooling effort to the payload chamber. The control and operation of the first fan and circulation of air through the device can maintain or vary the temperature within the enclosure and the payload chamber. The air circulated and cooled by the first fan can be residual air within the device such that air does not need to be drawn in from the atmosphere by the first fan, which would reduce the efficiency of the cooling. In this regard, the refrigerant material and heat sink or heat exchanger can act to remove heat from the residual air by the operation of the first fan. In addition, the first fan can assist in circulating warmer cool air from the payload chamber to the refrigerant material and heat exchanger or heat sink via vents, that separate the cooling and payload chambers.

[0079] The second fan can also be called the warm air fan since it sucks warm air from the atmosphere or outside and blows inside the payload chamber to assist in releasing the payload from the payload chamber. The control and operation of the second fan and circulation of air through the device can maintain or vary the temperature within the enclosure and payload chamber.

[0080]

In this regard, the regulation of temperature in the device and payload chamber can be controlled and varied by the operation (i.e. turning on and off) of the first fan and second fan intermittently. For example, if the payload chamber becomes too cold, the second fan can be turned on to draw warmer air from the atmosphere and mix it with the air in the payload chamber, whereby the first fan can be turned off. Alternatively, if the payload chamber become too warm, the second fan can be turned off while the first fan can be turned on to circulate air towards the refrigerant material and heat sink or heat exchanger.

[0081] In one embodiment, the portable dispenser device can have dimensions that range from about 9 to 72cm in height, about 7 to 60cm in length and about 7 to 60cm in depth. In one embodiment, the portable dispenser device can have a base dimension of 18cm (Height) x 15cm (Length) x 15cm (Breath) and can be further scaled down to 0.5x of the base dimension or scaled up to 4 times the base dimension. The device with base dimension can be considered as having small form factor and can be attached to the sUAV for transportation purpose.

[0082] FIG. 2 is a flowchart 110 pertaining to a method for dispensing the payload from one place to another, in accordance with the disclosed embodiments. As at step 112, the payload that need to be carried from one place to another place can be stored in a payload chamber of a portable dispenser device. Then, as at step 114, at least one refrigerant material is stored in a cooling chamber of the portable dispenser device. Cool air can be blown and circulated into the payload chamber, using a first fan, whereby the cool air is generated by the refrigerant material in the cooling chamber, as at step 116. An unmanned aerial vehicle or drone can be used to carry and aerially transmit the portable dispenser device with the payload from one place to another, as at step 118. As at step 120, a control unit can be used to control the various operation of the portable dispenser device, for example, the location, activities and telemetric parameters of the chamber that carries the payload, through a wireless communication means. As at step 122, the electronic unit of a portable dispenser device broadcasts the location, activities and telemetric parameters of the device, specifically the cooling chamber and payload chamber, to the control unit through at least one wired or wireless communication means to the control unit. As at step 124, the electronic unit may comprise a controller or servo control system to control the operation of the payload chamber, the cooling chamber, the first fan, the second fan and the door of the payload chamber based on the control signal received from the control unit. Finally, as at step 126, the payload can be released when the doors of the payload chamber are opened, using a second fan of a portable dispenser to assist in the release.

[0083] In one embodiment, portable dispensing device can be used for dispensing live insects. The insects can be first exposed to a low temperature of between 4°C to 10°C to keep them immobilized before being transferred to the device 101. These immobilized insects can subsequently be transferred into a payload chamber. To maintain the low temperature, a refrigerant material such as dry ice can be placed in the cooling chamber. The cooling fan circulates air cooled by the refrigerant material into the payload chamber where the live insects are kept. When the device is to dispense the insects, warm air from the surrounding outside can be drawn into the air inlet ducts with the aid of the warm air fans. Concurrently, the operation of the cooling fan can be stopped. The elevated temperature (equal or higher than 14 degree Celsius) allows these insects to start moving and flying. When the payload chamber door is opened these insects are herded out of the payload chamber to the outside. The continued flow of warm air from warm air fan 16 aids in herding these insects from the payload chamber. As will be appreciated, the elevated temperature to reanimate or awaken the insects may vary dependent on the insects to be dispensed and their physiology.

[0084] The device 101 disclosed herein can be generally defined as a mechanical and electronic device that is able to release insects of various species that are kept in hibernation or immobilized under low temperature between 4 to 10 degrees Celsius, preferably about 8 degree Celsius. The live insects that are released from the device remain alive and functional within the device. The device 101 can be attached to an unmanned aerial vehicle and can be carried as a payload. In one embodiment, the device can be releasably attached to an aerial vehicle easily within 10 seconds or less. In one embodiment, the device can be permanently attached to the aerial vehicle.

[0085] In instances when flown at high altitude, the device 101 can dispense live insects across a wide area based on Global Positioning System (GPS) coordinates or manual intervention. Every release from the device can be time stamped and location stamped. The time and location data can be uploaded on to a computer or on any cloud platform using radio frequency as a medium. This can include WIFI, 4G LTE, NB-IOT, Sigfox, Lora and so on. Such arrangement allows insects to be dispersed effectively and tracked anytime and anywhere in the world. The dispersed insects can be used for planned breeding for that species and/or deployed for interaction with other species, such as natural enemies, and/or deployed for pollination. In one embodiment, the device 101 can be carried by hand, packed in a bag or placed on a vehicle. In one embodiment, the device can be flown between 1 m and 600m in altitude Above Ground Level (AGL).

[0086] In one embodiment, the device can be used as standalone payload device and can trigger the release by hand or wirelessly using a mobile phone or via a long range Radio Frequency (RF) network, such as 4G or LoraWAN. Current technology allows very short range of control no further than 100m using 433 MFIZ or Bluetooth.

[0087] In another embodiment, the device can include a mission blackbox on board and provides the means to record information about its environment, location and activities. The log down data from the mission blackbox can be used for downstream analysis and troubleshooting.

[0088] In another embodiment, the device can be very small in the form factor, for example, weighing less than 1 kg. This reduces the need for large complex aerial system, such as an aircraft, for carriage and payloading, which can be expensive. There is no need for a runway or an aviation control tower to manage the sUAV. The dimension of the device has the base dimension of 18cm (Height) x 15cm (Length) x 15cm (Breath) and can be further scaled down to 0.5x of the base dimension or scaled up to 4 times the base dimension. The device with base dimension can be considered as having small form factor and can be attached to the sUAV for transportation purpose.

[0089] In another embodiment, the device can be attached to a small unmanned aerial vehicle (sUAV) with a minimum payload ability of 1 kg. Any sUAV smaller than a 0.9m x 0.9m and lighter than 5kg can be used to carry the device 101. There are many types of sUAV in the market that can be used to carry the device 101 as a payload. This leads to cost savings and provide ease of operation. The device 101 has a universal mounting point that can be easily modified for any sUAV and take less than 10 seconds to mount or dismount the device 101 .

[0090] The use of sUAV reduces the need for a highly trained operator, such as an aircraft pilot. The sUAV are less susceptible to weather restriction and easy to operate by programming the sUAV to fly a certain path autonomously.

[0091] In one embodiment, the device can transmit data to a computer or cloud platform using various wireless technology not limited to (Forth Generation) 4G, Wireless Fidelity (WIFI), Narrowband Internet of Things (NB-IOT), Sigfox and LoraWan. This allows the device 101 to be controlled by an operator or a computer program from a distance, remotely.

[0092] In one embodiment, the device can continuously broadcast the location, activities and telemetric parameters, such as power, temperature, humidity, voltage, pressure and so on, to the human controller or the ground control station anytime, anywhere. This allows the operator and ground control station to monitor the condition within the device 101 to ensure that important parameters are measured and provide early warning for any potential systemic failure. In this regard, the device can have built-in sensors in the printed circuit board (PCB) and within the chambers, for measuring and monitoring the telemetric parameters such as power, temperature, humidity, voltage, pressure of the payload chamber and the cooling chamber.

[0093] In one embodiment, a plurality of devices can used with each device able to broadcast their own unique ID (digital license plate) to a remote-control unit for identification and monitoring to ensure collision avoidance and separation assurance.

[0094] According to an exemplary aspect, there is provided a device 101 that is able to dispense live insects without hurting the insects. The device 101 can be releasably or permanently mounted on an unmanned aerial vehicle to raise the device to an elevated height to increase its effective area of dispense. The live insects are kept in an immobilized state and hence physical collision of the live insects are reduced. Their appendages (legs) and wings remain functional for flight, finding food and mating purposes.

[0095] Further, to facilitate easy handling of the live insects, these insects can be first exposed to low temperature between 4°C to 10°C. The temperature can be low enough to immobilize the insect so as to place them in a hibernating state, but not a high enough temperature that would lead to killing of the insects. The immobilization allows the handling of these insects with ease and allows them to be packed into the small payload chambers. The temperature of the payload chamber are kept low with the use of dry ice as a refrigerant material kept in the cooling chamber. A first fan can be used to circulate air cooled by the refrigerant material into the payload chamber. Upon reaching the desired height, the insects in hibernation or immobilized state can be awakened by warm air directed into the payload chamber by another set of air inlets and a second fan. At the same time, the first fan blowing cool air into the payload chamber can be turned off. Warm air from the surrounding outside can be blown into the payload chamber through an air inlet duct by one or more additional warm air fans. The warm air blown into the payload chamber raises the temperature of the insects and the insects become mobile again. A door of the payload chamber can be opened and the insects allowed to disperse out. The insects can be herded out of the payload chamber by the warm air. Thus, increasing the efficiency of dispensing. As will be appreciated, some insects within the chamber may succumb to packing stress in the process. Accordingly, the invention can keep the number of live insects’ survival to 80- 90%.

[0096] It should be noted that the device may be divided into two or more payload chambers. In one embodiment, each payload chamber can measure 6cm (height) x 4cm (Length) x 4cm (breath) but can be made bigger or smaller dependent on the overall size of the device and insects to dispense. The dimension of the payload chamber and cooling chamber can be scaled proportionately.

[0097] The death of live insects within the chamber caused by packing stress can be reduced by immobilizing the insects using the cool chamber and cooling fan. The appendages (legs) and wings of the insects are kept motionless and this reduce damages from collisions between the insects and collision with the wall of the chambers. Each chamber will house between 100 to 1000 insects depending on the size of the insect that can range from about 3-10mm.

[0098] The device can be attached to an unmanned aerial vehicle and can be carried as a payload. Any unmanned aerial vehicle with a payload ability of 1 kg can carry the device 101 on the underside of its hull. In one embodiment, the device can be easily attached and removed from the unmanned aerial vehicle within 10 seconds. Flown at an altitude, the device 101 can dispense live insects across a wide area based on GPS coordinates or manual intervention. Every release can be time stamped and location stamped. The data can be uploaded on to a computer or on any cloud platform using radio frequency as a medium. This can include WIFI, 4G LTE, NB-IOT, Sigfox, LoraWAN and so on. Such arrangement allow insects to be dispersed effectively and tracked anytime and anywhere in the world. The dispersed insects can be used for planned breeding for its species, interaction with other species, such as natural enemies, and/or for pollination.

[0099] The device 101 can be carried by hand, packed in a bag or placed on a vehicle. The release of insects or its payload can be trigger wireless or mechanically by hand.

[00100] In one embodiment, the device can require active insects to be first immobilized by keeping them in low temperature using solid dry ice (CO2) or cooling plate between 4°C to 10°C. The internal temperature of the payload chamber the insects are placed in can be regulated continuously by a micro-controller. The lower temperature causes the insects to be immobilized which lower the mortality rate. Survival rate of insects within the payload chamber can be between 80-90%. The insects can be kept at this lower temperature for at least 30 minutes.

[00101] In one embodiment, the device can be operated in multiple locations regardless of accessibility and can have multiple releases of insects. For example, the device 101 can have multiple payload chambers, each can be released at different locations and at different times, without any manual intervention. The exact route in which the device should travel can be easily created or can be selected from the list of already available routes. Similarly, a precise release time of insects can also be easily set or can be instructed remotely. The device have several payload chambers that can be cooled on its own and is capable of releasing the payload on its own.

[00102] In one embodiment, each payload chamber can function independently, such that its operation and telemetric parameters can be individually controlled using the remote device.

[00103] In one embodiment, the insects can be mosquitos. In one embodiment, the mosquitos can be Wolbachia bacteria infected male mosquitoes. Specifically, through the release of such male mosquitos’ their subsequent mating with wild-type uninfected females, will result in sterile eggs being produced and a reduction in the mosquito population in that area or region.

[00104] In one embodiment, the device 101 can be used to carry biomedical lifesaving biologies, such as vaccines, antibodies, anti-venom, insulin, injectable adrenaline (for critical anaphylaxis). The payload chambers can be modified via its size and shape to fit the dimension of the biologies to carry the payload.

[00105] In one embodiment, the device 101 can be used to release seeds over large area for farming purpose. The payload chambers can be modified via the size and shape to fit the type of seeds to carry the payload. If the payload to be carried is unanimated or affected by heat or cold, the heating/cooling system can be removed.

[00106] FIG. 3 is a block diagram of a portable dispensing system 200 for dispensing a payload, for example mosquitos, from one place to another, using an airlifter 210, in accordance with the disclosed embodiments. The system 200 can include the airlifter 210, a wireless communication means 206 and a control unit 208. The airlifter 210 can include a drone 204 and a dispensing device 201. An example of unmanned aerial vehicle is a drone 204, can be used to lift and transmit the dispensing device 201 from one place to another. The drone 204 can be flown manually or unmanned. The dispensing device 201 can comprise of a payload chamber 207, a cooling chamber 212, warm air fans 205, cool air fans 211 , a WiFi module 202, a camera 203 and a servo control system 209. The payload chamber 207 can store the payload to be transfer from one place to another place. The operation of the cooling fans 211 can maintain a desired temperature in the payload chamber by the circulation and directing of cool air from the cooling chamber 212. The release of the payload can be activated by connecting a control unit 208, for example, a mobile phone to the WiFi module 202. Just by pressing a button on the control unit 208, the servo control system 209 on the dispensing device 201 will turn on, releasing the payload into the surrounding area. The warm fan 205 will also be activated so as to blow out any remaining payload in the dispensing device 201. The control unit 208 can be a hardware controller and/or software controller. Further the camera 203 can live stream the surroundings of the drone 204 during flight. The airlifter 210 can communicate with control unit 208 through the wireless communication means 206.

[00107] The drone 204 can be programmed to fly autonomously to cater to inexperienced personnel when flying the drone 204 and also allowing only one man to control the airlifter 210. Other than that, a 360 degrees obstacle sensor can be mounted on the drone to aid in guiding the drone to the designated location safely. The payload chamber 207 of the dispensing device 201 can have more compartments thus allowing release in multiple blocks per trip. The total weight of the drone 204 including the dispensing device 201 can be 5 kilograms, however with 100% power it can carry up to 12.6 kilograms. With 100% battery capacity, the drone 204 can lasts for 11 minutes. The transmission range of the drone 204 can be about 4 kilometers (Km) and the range of the controller for the dispensing device 201 can be between 4 to 5km. The dispensing device ensures that no one can connect unit 208 to the WIFI module 202 by using personalized password into the code, so that only the operators are able to access and operate it. In order to prevent any accidents from happening, operators can be required to have vision of the drone 204 while flying. When the drone 204 reaches the destination, the operator can ensure that there are no people nearby before releasing the mosquitoes.

[00108] FIG. 4 is a perspective view of a portable dispensing device 300 used for transporting and dispensing the payload from one place to another, in accordance with the disclosed embodiments.

FIG. 4 shows the housing or casing of the device that encloses within or secures the components of the device. In particular, the second fans 314, 414, 514 can be secured to the housing or casing of the device via air inlet ducts or passageways 316, 416, 516. In addition, the servo control systems 320, 420, 520 can be secured to the housing or casing of the device at the bottom for operational control over the door for each payload chamber.

[00109] As shown in FIG. 5, the device 300 can have four payload chambers 318, 418 and 618 (shown only three of four) for holding and storing the payload, not limited to the insects, seeds or biologies, which are to be preserved at certain temperature in the device 300 during transit. The device 300 further has a cooling chamber 328 positioned on top or above of the four payload chambers. The payload chamber and the cooling chamber can be divided by a separation plate. The separation plate can include vents 312, 412 and 612 (shown only three of four) that allow air from the cooling chamber to flow into the payload chamber. The housing or casing of the device can be made of insulated material and hence internal temperature of the device can be preserved with minimum or no heat transfer to the outside environment.

[00110] The cooling chamber 328 can include one or more refrigerant materials 306, for example dry ice, electronic cooling plate or Peltier. In one embodiment, a heat sink 310 can be placed below the refrigerant materials in the cooling chamber, such that the heat or cold energy from the heat sink 310 is transferred to the payload chambers, when the respective first/circulating fans or cooling fans 308 are operated. Cooling of the payload chamber cools the payload placed inside the chamber. The temperature of the payload chamber can be maintained based on the type of the payload inside the chamber. For example, insects can be first exposed to a low temperature of between 4°C to 10°C to keep them immobilized before being transferred to the device 300.
