CA2837433A1 - Core data cube & core chipset - Google Patents

Abstract

This patent outlines the design and fabrication of a computer system intended to facilitate communication between wheelchair users and institutions. The system is predicated on a chipset encompassing a laptop motherboard, communication chipset and a drive mechanism. This assembled chipset can be installed in various different cases; a rugged wheelchair version or a cubic styled institution variant supporting multiple touch interfaces on each axis.

Description

Intro As the system in this patent is predicated partially on the chip set proposed, the secondary component of the patentability of the devices is the design features of the casings. This system requires two separate casing styles to fulfill its objective (img 2.2 &
3.1). The first casing described is termed by the inventor the 'Independence Core Wheelchair Computer System', and the second is the 'Core Data Cube'. These names were chosen as the term 'Core' is not a trademark, but rather a describing verb indicating the heart of a component with specific attributes. Independence Core is intended to provide independence to individuals living with disabilities and the Core Data Cube is a cube shaped device. Further devices will carry the term 'Core' so long as they will support being integrated into the same overarching system.
The Independence Core is a wheelchair mounted computer system integrating modern technology and telecommunication infrastructure into a versatile and dynamic case design; it is a hardware platform. The Core Data Cube was derived from the Independence Core chipset developed in 2011 and 2012. The Core Data Cube is designed to be a multi-user computer terminal capable of supporting four simultaneously users or administrators. The system varies considerably from commercially available computer systems with some considerable departures, and there is a specified function and application for this device.
Assembly is relatively straightforward in theory, but more complex in execution. For the chipset, a laptop motherboard with battery system is connected to a wi-fl telecommunication uplink, GPS, blutooth, drive mechanism and solid-state hard drive.
They are encased in a water and shock resistant case along side a cooling fan.
For the drive functionality, a missile launcher control chip is wired into a series of relays that are connected to a battery. The feed from the battery is directed to DC motors by the activation of electric relays. The power is shunted through full bridge rectifiers and out to the power chairs electric motors or any other direct current motors (DC
motors), this permits steering of the chair.
The Core Data Cube's case is equipped with powered and non-powered wheels that are attached to the bottom panel and sides of the case. Four touch monitors are fastened onto the side of the cube (in the future to the lid as well as the base), and the chipsets described above are placed into the interior of the cube and secured. The systems (is) are then wired up appropriately. A battery is inserted into the cube to power the wheels and auxiliary systems. A lid is fastened to the top of the cube and the lid includes a fan for ventilation and peripherals.
This is a full system configuration. On a practical level there is more complexity, but overall this design can easily be emulated and thus sets the requirement for a patent of non-obviousness and originality.

The notion of a cube styled computer with 4 (or six) touch displays is novel, as is the Independence Core design, and the chip structure encased in the computers. The design features that are included in these models may radically divide this series of device from existing manufactured devices.

Background In 2010, I was hired by Scadding Court Community Centre (SCCC) in Toronto, Canada to design and build some public computers for patrons with visual disabilities. Upon completion of the units I was retained to run a camps for adults living with disabilities.
Many of the participants were wheelchair bound and some had varying severities of Cerebral Palsy. At some point during the engagement, I attempt to build a peripheral computer device to permit quadriplegics to control a computer with their tongue, as many paralyzed individuals retain set functionality (Inter-Oral Touchpad patent CA2718303A1). Concurrently around this time period, the management at SCCC
funded me to develop a video conferencing system to assist participants whom were unable to attend weekly meetings. This project was a failure as the technology present, the severe limitations of users and the upkeep of the system were not congruent. In the summer of 2010, while I was conducting research for what would become the Inter-Oral Touchpad, I
was hired by a private clinic within the Sunnybrook hospital campus named ATC.
At ATC I was exposed to further Assistive technology including eye-tracking cameras. I
ended the position at the end of summer 2010 to focus on my university degree.
After returning from abroad in mid-2011, I commenced building a complimentary computer system to support the functionality of the Inter-Oral Touchpad, and to integrate the functionality required to enable the system requested by SCCC. The system ended up including a water resistant case, laptop with adapter, GPS, wi-fl telecommunications integration, blutooth, a solid state hard drive, up-front touch monitor, speakers and camera. The systems were built by mid 2012 and function adequately.
Through the end of 2012, I tested out further features that for the system, developed some software code, designed specifically Graphics user interface and worked with staff at Centennial College in Markham to build an initial website. In March of 2013, I
purchased an old power chair from an individual in Toronto, and I set upon configuring the Independence Core computer system to navigate and control the power chair. By mid summer 2013, this feature was achieved by using a output chip derived from a novelty USB missile launcher and building a relay based printed circuit board (PCB) chip to feed power to electric DC motors. By the end of May 2013, I was able to drive the chair from the computer as well as being able to remotely log into the chair from a tablet computer, desktop PC or Independence Core and control the chair over the Internet.
Through the summer and fall of 2013, I commenced to build and program an open source eye-gaze eye tracking camera as found online.
With these milestones reached, my attention was directed to the Core Data Cube system.
The Core Data Cube is intended to be the backbone of the system, where the wheelchair computers act more as Satellites. The Core Data Cube is a four-sided computer system, which is cubic in shape. Each of the facing sides has touch screen monitors.
Inside the system there is (are) two Independence Core chipsets, which ensures compatibility with the wheelchair computer systems across networks. This includes motherboards, GPS, wi-fi telecommunication integration, drive functions, a drive relay array, and a battery system. As well, power adapters are integrated.
The goal of the system is to be able to produce and support a virtual private network across wheelchairs and to integrate the Core Data Cubes into location that would benefit from communication with the chair users.

Prior Art.
All of the laptops, chips, the wheelchairs, displays and other commercially available technology are covered under their own individual patents. The system being proposed in this patent is similar to other existing computer systems in the regard that it is formed from mass produced electronic components, yet differs in design and application. For example, there are other market available wheelchair mounted eye tracking computers, but they tend to be standalone units, which present barriers to integration into cohesive infrastructure projects. There are also computers that drive power wheelchairs; and these vary across the spectrum from small micro-processors which control the majority of power wheelchairs, to prototypes of autonomous wheelchairs that use advanced circuit board designs, software, optics and GPS.
The proposed system is different because it tackles many of the short-comings of existing devices and anticipates what changes would have to be made to model a device capable of being used by more individuals in an advancing technological society. Chip design, Battery design, case design, the grade of the components, and the software suits being applied are what significantly differ the device from other existing machinery.

Kaufman, 1, 1994 tracking interface George J. Piligian Independence Core Chipset The system is best divided into sub-components to properly describe the manufacturing process. The individual components are integrated into the chipset. The chipset is housed in the Independence Core casing or the Core Data Cube depending on which model is being manufactured. At present, the Core Data Cube is powered by two individual Independence Core computer systems. (img. 3.2) Chipset The Core chipset is predicated on a netbook or small stature laptop motherboard; which comes equipped with RAM, a hard drive, battery system with 120 volt adapter, wireless fidelity enabled, and interface methods to connect physical USB peripherals.
The hard drive is replaced with a solid-state hard drive to increase durability. The motherboard is connected to a USB hub; which provides additional USB ports to connect the computer to a Global Positioning System (GPS) transmitter-receiver, Bluetooth sender-receiver and a telecommunication enables wireless fidelity (wi-fl) device that permits the computer to be tied into telecommunications providers infrastructure (It is my desired that this will eventually be a fully integrated and unified chipset instead of being piecemeal). (img. 2.2) Further USB slots are used to run fans and to connect a solid-state external hard-drive;
which is adjacent to the netbook motherboard and acts as redundancy and an easily transferable data backup. Further USB ports are used for extending a charging cable out to the upfront display and rear displays, upfront control devices, and to tie into the drive mechanism. In all, about 10 USB ports are presently used.
The netbook computer case required disassembly and modification. I soldered wired onto the mother boards On/Off switch to extend the power button to my choice locations on the external case, and I removed the magnets in the laptop screen which indicate to the laptop when the screen is closed to enter standby mode. This allows the computer to turn on when physically closed.
The chipset proposed here is key to the functioning of the device, and is of key importance to patentability in regards to originality and non-obviousness of the design.
No existing manufacturer known of has this style of chipset. The exact nature of the drive mechanism can be changed significantly from that described here to a digital styled circuit or even alternate analogue circuits to increase efficiency, but of importance is the integration of a drive circuit into the casing of the laptop.

Casings:
The Independence Core computer system can be attached to wheelchairs or hospital beds in many ways including a handing bag or with support brackets. Mountings the Independence Core to almost any wheelchair is capable through support bracket within the devices frame. (img. 2.1) The Independence Core case is a rugged & solid casing, which in prototypes opens along the lateral plane. In my prototypes I used a Pelican brand 1095 case to secure the internal components. I used a Pelican case for the prototypes, as the cases are water resistant, durable, shock resistant and very secure. I cut three holes in the case, one for the power button, a second as a cable feed hole and the third as a fan ventilation hole.
The fan ventilation hole was covered up with a laser cut plastic grate to protect the fan and give aesthetic appeal to the design, a fan was affixed to the inside of the hole to promote air circulation. Inside the case the motherboard, fan, usb peripherals, motherboard adapter and battery are secured to the pelican case.
The cables feed out of the cable hole; and tend to be limited to a single power cable and two data cables. On a more advanced models such as the ones used in the Core data Cube, I also ran VGA & HDMI video cables, audio cables, and multiple USB
cables to provide additional options. On a wheelchair model, a USB cable is run from the Independence Core to the up-front and attendant displays to permit constant power charging of the tablets and components. A second tablet is mounted in the back off the chair either directly to the independence core or to the chair itself using a bracket and acts as a attendant system permitting driving and control from the back, this system is also connected to the power system for constant charging.
The netbook power button (which had been extended) was connected to an on/off button installed into the pelican case. A switch was wired to this button as well to permit me to extend the on/off power to any location I choose fit by simply completing the circuit.
The Independence Core is then securely closed to prevent damage or water seepage. In the Independence Core prototype, the drive mechanism is external to the pelican case as it is too large to fit in the case, but in the future they will be both be enclosed in the same casing to form one self-contained package and hopefully integrated into the same single PCB microchip. The front of the independence core is fitted with a series of protruding partitions' which form the outline of containment area to hold the upfront &
attendant displays when they are not in use; this makes storage, transportation and charging simpler and more convenient. (img. 2.2) The upfront and attendant displays are a touch screen display (originally a 7"
USB touch monitor,) speakers, and (rotating or stationary) digital optical camera and Eyegaze system integrated into a small laser cut casing. This laser cut casing can be affixed to the front partition of the Independence Core for transportation and storage, and is able to be removed from the Independence Core to be connected to a wheelchair via a mounting.

The laser cut case can connect to an angular support, which will connect to the wheelchair attachment bar. This permits the system to mount directly to the wheelchair within proximity to the users fingers. (img. 23 & 2.4) In later development models, I substituted a Research In Motion Blackberry Playbook and a Asus Nexus Tablet instead of customizing the upfront LCD touch display.
This replacement removed many technical difficulties associated with power consumption and software of peripherals. Once the upfront tablet design is completed, it will be modular enough to fit into the Core Data Cube casing lid so that all the systems produced will have compatible and interchangeable components. (img. 3.4 & 2.2) The tablets which act as displays, are interfaced with the Independence Core systems through 3rd party software, in this case I used Splashtop remote software.
This permits the tablet and the computer to control each others central processing unit and for the user to see the effects on the opposing unit. (img 1.1 & 1.2) To increase accessibility for limited mobility users, a 3rd party peripheral is used. The ideal one is a miniaturized presentation cursor, which allows individuals to use only the tip of a single finger to control the entire computer operating system via additional software programs, as well miniaturized Bluetooth keyboards are used. These 3rd party systems are wireless and use Bluetooth protocols.
At present an open-source Eye-gaze or eye tracking camera is being built into the system and it will be integrated into the casing of the tablet display. This feature will permit the user to control the entire system via their eyes if they are incapable of operating the computer through any other means. (img. 2.3 & 2.4) Core Data Cube The Core Data Cube is a different case fabrication utilizing the same chipset described.
The Core Data Cube as a prototype is different than the finished model is intended to appear, but only slightly due to resources available at the time of construction. The Core Data Cube measures about 20 inches by 15 inches per side and stands about 15 inches tall; but this size is arbitrary and I would like to reproduce it in variable sizes from one or two inches to six feet or more. As well the prototype does not include certain features such as its own drive control chip, DC motors and an extensive battery system due to limited resources, but future models would include all of these.
The Core Data Cube is a four-sided (and later six sided when technology permits) computer system that encompasses a touch screen display on each side. (img.
3.1, 3.2, 3.3, 3.5 & 3. 6)The touch screens are ideally sourced from durable and impact resistant materials such as Gorilla Glass' or military grade ballistic glass to improve the durability of the screens and their longevity. The case is presently made of half inch thick plexy glass sheets cut to 15 inches high by 19 inches wide by 15 inches deep, these form the foundation base of the device. The plexy-glass is bolted together with brackets at the top section of the box about 3 inches from the top on the inside, as well as about half way down the inside of the box. On the bottom, caster wheels have been fitted that encompass flanged angels allowing bolting of the bottom and side pieces of plexy-glass to the casters. One inch bolts and nuts were used to secure the parts together. This forms a rigid structure to support the internal and external components. All holes must be pre-drilled to prevent damaging the plexi-glass. A sheet of plexy glass was cut to size and acts as the bottom, which sits recessed about 3 inches above the bottom plane of the sides of the box, and gives an area to mount the caster wheels, as well as DC drive wheels underneath the box. As such the caster wheels extend about half of one inch from the bottom of the box.
The inside depth of the box is about 12 inches deep permitting an area for the components to be integrated into the internal structure of the case. The box was painted black for aesthetic reasons and can be made of many other materials including punched, stamped, or formed metals, plastics, blow-mounded light weight plastics, polymers, fiberglass, carbon fiber, etc. The overall style of the box and system can differ greatly depending on style, design and material fabrication.
The screens on the prototype come equipped with mounting screw holes, so corresponding holes were drilled in each side of the box to efficiently mount the four screens. In the future, screens will be integrated into the framing of the Core Data Cube, ensuring they are water resistant and protected from external impacts. They can also be covered with retractable covers that manually slide or are electrically powered. Two round holes with a diameter of 1.5 inches were cut in the side of the box near the bottom corners with a bell saw or a large bore drill to act a cable feed hole. All four screen were wired up with their power cords, video inputs (hdmi or VGA) and the two side screens which are manufactured as tvs as well, were fitted with co-axle cables for cable television. For the touch screen monitors, and speaker enabled monitors, the audio cables and touch screen data cables were also fed through the cable holes. All four screens were mounted to the box using one-inch bolts.
The cables are colleted and carefully secured. Next the cables that provide data are fed into the Independence Core systems through its cable feed holes. In the prototype Core Data Cube there are two Independence Core systems linked together by a LAN
cross over cable permitting data sharing across a hardwired infrastructure; but the chipset can be done with only one Independence Core chipset or it can be done with multiple chipsets depending on the capacities of the motherboard and the desired intent. The systems can also share information across a VPN instead of a cross over cable. The functionality of having multiple chipsets ensures redundancy if a component fails while in use, and increasing longevity. The computers connect to the VGA and HDMI cables, as well as the touch screen data cable and audio cable. The auxiliary power on/off cable that was extended earlier within the Independence Core is also fished out and bundled with the rest of the wires to be positioned on the Core Data Cube casing.
Carefully one Independence Core is slid into the box and the wires are moved to the corners of the box where the pelican cases rounded corners permit area for feeing cables.
Once one Independence Core has been fit into the box, the second Independence Core is fit in horizontally on top of the first system, and the cables and wires are fished out of the box to be organized. At this point a cable splitter is connected to the co-axle cable feeds for the televisions. The power cords for the monitors, Independence Cores and auxiliary battery systems are plugged into a power bar with additional open plugs for expansions.
The power bar at present sits above the independence cores. In the future power integration will be designed into its own place along with the auxiliary battery system and wiring for the DC motors. USB hubs are connected to additional USB ports on the Independence Cores; and each run keyboard and mice as well as fans and support additional open ports.
In the future models, the electronics will be miniaturized and will have many ways of fitting into the system. The full void of the cube which is presently filled to near capacity with large Independence Core systems and cables will be opened up as the systems are built into small compartments in the sides and bottom of the system and the external fitting monitors will be recessed into the body of the cube. This will permit an open void in the inside of the cube that can be used to install other things into it.
(img. 3.3, 3.4, 3.5 & 3.6) [It is worth noting that this system could be manufactured by connecting a number of tablet computers together against a sold cubic base, but that style of device would be lacking some present functionality and a drive option, and I feel would be inadequate to be able to be developed in the future. As such it is more than just four tablet computers in a square shape.]
The Lid At present the lid of Cube is plain with brackets on each side to hold it in place. A hole has been cut into the top allowing a light bulb to be fitter to the lid and provide light from a desk lamp, and an additional USB ports for component charging and data transfers. As well there is a power cord that extends to a wall socket, to power the system and recharge the battery cells. (img. 3.4) Originally, the lid was supposed to hold two rotating digital cameras providing 360 degree bi-focal vision to the computer systems, a tablet (RIM Blackberry Playbook), speakers, additional USB and 120 volt AC power port. (img. 3.4) The lid can be fitter with the laser cut display designed for the Independence Core as well as a tablet computer, cellular phone, microphone and other various compatible electronics;
the goal is to be able to integrate widely available commercial electronics into the lid of the system. In time the lid components will probably be positioned under the top facing screen to supply storage; and will be able to be accessed by tilting the top facing screen and sliding it parallel behind one of the vertical screens along a track.
(img. 3.1, 3.3, 3.4, 3.5 & 3.6) By doing such, a void area within the Core Data Cube can be exposed permitting accessing to the internal components housed within, storage, expansions or positioning of external objects within the void. This would provide a myriad of functionality. (img. 3.6) There are three other things that are presently being built and integrated into the system in addition to the battery system and drive system. One is an open source Arduino chip that will fit into the Core Data Cube to permit users to prototype their own devices, gives expansion and customization options. (img. 3.4) Second, is an open source pupil tracking cameral known as an Eyegaze system. The Eyegaze system will allow users to control the whole system with the use and navigation of their eyes alone. At present both systems are in development not yet completed enough to be built directly into the Independence Core or the Core Data Cube; but it is a defined objective and presently being undertaken. (img.

2.3 & 2.4) Third, is the option to make the chipset and the screens two separate boxes that would slip into each other like matryoshka nesting dolls which would remove many of the issue associated with wire placements; this would retain a void space and improve durability and maintenance of the Core Data Cube.

Drive mechanism:
The drive mechanism chip component is two microchips combined to facilitate a specific objective. A navigation chip derived from a USB missile launcher and a customized electric relay chip designed to shunt power from the main battery source to external electric devices such as wheels or servos; combine to allow the windows operating system to control the movement of the device or activation of components.
(img. 1.1, 1.2, 1.3, 1.4 & 2.1) The drive mechanism navigation chip is a microchip that is derived from novelty USB
missile launchers. The novelty missile launcher was disassembled and the chip was removed and most of the wires were cut save the yellow and red wires as well as the red and brown wired (may vary depending on manufacturing batch). These wires control electrical impulses that will permit left and right turning as well as forward and backwards movement. The chip sends 4.5 volt signals out through the pairs of wires in either positive or negative fields. The chip software is provided by the manufacturer. The yellow and red wires, as well as the brown and red wires are fed into a custom designed circuit board which controls a pair of DC motors on the wheelchair and Core Data Cube but can easily be configured to control a host of other devices.
The custom designed circuit board used to drive the motors in my prototype is a series of electric relays which funnel current from a large battery to the DC motors.
(img. /.4) In the case of the power wheelchair, it is the power chairs' own battery and for the Core Data Cube, it is from an integrated onboard battery. In the future the chip will likely be a digital chipset as opposed to an analogue chip, but for this instance I will indicate how to assemble the rudimentary analog chip. As well, the chip will be expanded in the future to support more than only a pairs of outputs, and will be able to control dozens of DC
motors and devices instead of only a pair of DC motors.
The requirement for the chip are a:
An empty circuit board (PCB) A wire tray (12) relays 5+volt (4) full-bridge rectifiers (8) rectifier diodes 18 gage solid core copper wire with heat resistant coating Electrical connectors A box with mounts to hold the finished chipset Solder/flux/soldering iron Step 1 - The wire tray is mounted and secured to the PCB.
- The drive chips' wires are fed into the wire feeds, as are the external wires that will connect to the major external battery or power source to energize the DC
motors.
- The yellow and red wire are isolated and tested to determine which wires send and receive the positive and negative currents. Once this is established, rectifier diodes are soldered at the ends of the wires and the relays to complete the circuits and prevent crossing circuits.
- The same process is undertaken for the red and brown wires.
- Secure 4 of the [5 volt] relays to the PCB in an organized line.
- At this point the drive chip controls individual relays capable of shunting power from an external source.
Step 2 - A circuit is made to connect each of the four original relays (referred from here on wards as <) to the 8 subsequent ones ( referred here onwards to as >).
- An external battery is produced to control the subsequent 8 relays. This is capable of being done from the major battery source if run through a power adapter, but on the prototype, this is a small 6volt (4x AA battery) source just to run relays.
- One of the 6volt source wires is connected to the contact ends of the 4 initially set relays and will form a opening/closing circuit with the 8 subsequent relays.
- On the subsequent relays terminals, a wire will feed back into the 6volt battery to complete an opening and closing current.
- The 8 subsequent relays will be connected in tandem pairs; two relays will be opened simultaneously to permit inflow and outflow of current on two individual circuits within one flow pattern. These tandems pairs will operate the positive and negative current flows simultaneously. All of the relays in on line will connect to the same major positive power source, and all of the relays in the second line will connects to the major negative power source.
- To functionally build the circuit and prevent only one relay from opening in >, a rectifier diode is inserted onto the 6volt in-bound wire.
- The 8 subsequent relays are connected to the PCB in 2 organized rows of four.
- The wires connected to < create a circuit with >, capable of opening both of the >
relays at once when < relay is activated by the drive chip.
- Now when the drive chip is used, three relays open in two separate circuits and a new circuit can be passed through the contact openings of > which can be of an independent circuit.
- The primary battery source used to drive the DC motor is connected from the wire tray to the contact leads of the relays set in tandem.
- The first set of 4 > relays are used as positive voltages (+), and the second set of 4>
relays is used as negative relays (-).
- Four full bridge rectifiers are connected to the PCB board.
- The open contacts of >+ are connected to the full bridge rectifier at the positive terminals.
- The open contacts of >- are connected to the full bridge rectifier at the negative terminals.
- From the two remaining positive terminals of each full bridge rectifier, a wire extends from each terminal. We are left with 8 leads.
- A wire connecter is used to bundle and separate wires.
- Each wire connecter used in my instance was derived from a electrical supplier dealing with lighting fixtures, and has two incoming feeds for both positive and negative leads and outs to one lead, and supports a disconnect between the two halves of the device. -Essentially, the two wires will form up to become one wire.
- As each DC motor used has one positive and one negative lead and depending on which lead power is introduced through, the motor rotates clockwise or counter-clockwise.
-Mount the finished Chipset in a secure mounting casing.
Step 3 Summary By this point on the PCB each of the series of relays and a full bridge rectifier act to open a channel which will funnel power through to the wires at the end of the full bridge rectifier.
Each of these series controls a motor direction including forward, back left and right.
To have a DC motor travel forward, the positive current is funneled through the proper leads of the DC motors in concurrently.
To reverse, the positive current is fed into the negative feed.
To turn left or right, positive feeds are funneled into the positive and negative feeds of the DC motors and making them rotate in opposing directions resulting in a turning motion.
For the DC motors to work, there has to be a clear path of power in and out, and as power takes the path of least resistance, the circuits have to be secure.
The full bridge rectifiers take their negative lead and cross them over to another set of relays. So, forward > out the backwards >; and left > outs to Right >. This permits power to be drawn in from the negative terminal of the backwards full bridge terminal;
the negative terminal of the left full bridge terminal, etc.
To recap, power from the drive chip trigger a selected relay, which opens two more relays. Those relays funnel main power to DC motors through the open contact openings and through a fullbridge rectifier. To prevent loss of power from a source of least resistance, a cross over is performed in the circuit and power is removed back to the battery from the opposing leads of the DC motors.
This system including the drive controls can be connected to a wheelchair to permit to the chair to be controlled, similarly it can be attached to various other machines that use DC
motors and have their own battery source. If mounting the drive mechanism to the a power wheelchair is desired, a proprietary control box is often available rendering this system obsolete. Otherwise, the primary power leads are spliced to permit charging from the wheelchairs proprietary charging unit to the master battery. Splicing in the feed through the drive control relays, and out to the motors through the full-wave rectifiers leads permits controlled navigation. In my prototype, the wheelchair motors had to be disassembled to deactivate the manual locking mechanism built into the motors, then reassembled. In future models this issues will be resolved alternately as it voids warranties and deactivated emergency brakes causing health risks.
This system assembly design may result in some problems as the design was revised extensively and multiple alterations were made through the course of fabrication, but to the best of my recollection this was the assembly procedure.
