- Fig 1 is an exploded perspective view illustrating the key components of a personnel identifier of Example 1 ;
- Fig 2 is a perspective view of the device.
- Figs 1 and 2 illustrates a "Personnel indicator” light emitting device (10) specifically designed to be fitted to the rear of a helmet. It comprises a shaped casing (12a; 12b) and the functional components (14).
- the basic functional components include: • a plurality of LED's (16a) (including one or more of white, infra red, and coloured LED'S) in a light assembly (16),
- the functional components (14) including the LED's and light assembly, the rechargeable battery, the solar cells or panels and the processor, are held together on a tray (26) or are embedded in a resin or resin like material.
- This tray is than sealed in the casing (12a; 12b) comprising a lens or clear cover (12a) and a backing (12b) which gives the end product it's aesthetic qualities and a degree of water resistance.
- the “miniaturization” of the device reduces weight, an important consideration in military applications.
- the casing can be as little as 9cm x 4cm x 1.5cm (length, width, depth).
- the casing (12) may be configured in a number of ways including, for example, i) a hollow injection molded plastics (as illustrated) with a clear front face (12a) and an opaque back housing (12b).
- the hollow being filled by the tray (26) (which may be a one piece or two piece construct) onto or into which are fitted the major components (14).
- the front (12a) and back (12b) of the casing (12) are sealed around the tray (14; 26).
- the opaque back housing assists in reducing stray lighting; ii) an injection molded plastic case, filled with a suitable electronic potting compound, such as, for example, an epoxy resin, to provide, amongst other properties, structural reinforcement and waterproofing; and iii) an epoxy resin case (not injection molded) comprising a clear resin front face and an opaque back.
- a suitable electronic potting compound such as, for example, an epoxy resin
- the "Personnel indicator” light emitting device (10) comprises at least three light boxes (16), each lit by at least one LED (16a) which may be either:
- One of the three light boxes or an additional light box may additionally, or in the alternative, carry an infra red LED.

- the different colours/ combinations enable at least 3 modes of operation (independent of the infrared signaling capacity) to be pre- programmed.
- the LED's used can be controlled via the processor (22) to provide light at different intensity (dim or bright settings). However, a similar effect can be achieved by, for example, lighting one or two LED's.
- the LED's can be used to generate a point light source rather than a diffused light as achieved using the light box.
- both the coloured and infrared "light intensity” can be varied and respective light boxes can be switched between an “on”, an “off” and a “pulsed” mode. Pulsing can also be controlled so that either a single colour is pulsed or alternate colours (including infrared) are pulsed.
- Fig 1 The product illustrated in Fig 1 is programmed so that it can be switched between at least 3 modes of operation which can be controlled from a switch (24) which can be either a contact or a contact-less switch.
- the 3 modes of operation include:
- first intensity (dim)
- first colour e.g. green
- central light box • 1 st mode of operation - first intensity (dim), first colour (e.g. green) with optionally infra red on (central light box);
- the switch is a contact switch and the mode of operation is time sensitive.
- the switch will take the program through the alternative cycles (mode 1 to mode 3) in a time dependant manner. It will be apparent that alternative switching modes and initiation/ change programs may be used.
- an audible indicator is additionally provided to let the user know which mode he has selected. This is significant as the identifier is attached to the rear-of a helmet.
- the indicator will be activated by depressing the contacts (via the switch) in the following manner: • When the contacts touch for a 1 st preset period, in this case 1 continuous second, the indicator activates the first mode of operation;
- the indicator activates the second mode of operation; and • If the contact is maintained for a 3 rd preset period, yet another 1 second, the indicator activates the third and final mode of operation.
- the indicator is programmed such that, whichever mode of operation is active when the contacts are released (1 st , 2 nd or 3 rd depending on length of contact time) it will remain active until the indicator is powered off. To power off the indicator, the user will hold the contacts for a given period, 2 seconds. This action will shut off the indicator regardless of which mode of operation it is in.
- the unit may optionally be configured to automatically shut down when exposed to daylight for an excess of a predetermined time period, say 10 minutes, to preserve battery life. Additionally, if it turns off in these circumstances, the indicator can be programmed to provide an audio feed back warning.
- the rechargeable battery should be able to provide sufficient power for the duration of use required.
- Preferred batteries include those selected from the group consisting of Nickel Cadmium, Nickel Metal Hydride, and Lithium ion.
- the batteries will be capable of replacement independently of the other components. This is significant given new recycling requirements.
- the batteries are encased with the other functional components (14) in e.g. a suitable electronic potting compound, such as, for example, epoxy resin, the batteries will not be independently replaceable.
- a suitable electronic potting compound such as, for example, epoxy resin

- the device is charged solely by solar power.
- external charging points may be provided allowing mains or battery charging and/ or an auxiliary battery provided.
- the device will require additional contacts (34) capable of docking into the charging caddy. These contacts will need to be unaffected by moisture or stray contact. Alongside such contacts it may be desirable to include a set of contacts for dynamic programming of the device.
- the unit should be able to recharge with the following characteristics: • 24 hours of dim first colour (green) plus IR usage will be recharged by exposure to full daylight for 8 hours;
- the device has solar panels positioned on a substantial portion of the front face of the device (the primary surface). In the embodiment illustrated two curved solar panels are used and these are fixed in the tray (26) within recesses (30). In an alternative embodiment solar cells or a panel may additionally provided along an upper surface of the device.
- the reverse of the tray (26) not shown is shaped to house the rechargeable battery(s) (18), the processor (22) and the audible means (not shown). It may also house an auxiliary battery.
- the shaped casing (12) is further provided with an attachment means (32) which takes the form of a buckle allowing the device to be attached using a webbing strap or similar means to a helmet.
- the device may be controlled to automatically shut down when exposed to daylight for a given time, say in excess of 10 minute.
- a vehicle identifier is described without reference to additional figures as the component elements (14) are substantially as per Example 1. However like number references are used by way of explanation. The primary difference lies in the shaped casing (12) and the attachment means (32) provided thereon.
- the vehicle identifier is primarily intended for use by the military for vehicle marking.
- Three alternatively coloured LED's (16) (or a single tri-colour LED whose colour can be controlled via the processor (22) is/ are provided, optionally in a light box (16).
- the three colours are typically:
- the LED's are arranged around the perimeter of the device which may, for example be a square device of approx 150mm by 150mm, (depth 25mm).
- the central region comprises one or more solar panels or an array of solar cells (20).
- 8 LED's (16a) are equidistantly disposed around the perimeter to provide 8 point lights.
- four light boxes (16) may be used to light the perimeter.
- the light boxes function by reflecting the light from the LED in a manner that the box is evenly lit. This provides a more even light than that generated by a single LED which typically generates a point light.
- One or more infrared LED's may also be provided.
- the LED'S can be operationally controlled so that the number of depressions (or alternatively time period of depression) selects the colour.
- An example of this is set out below: Press once Red
- the user may, for example, depress the button for a set period, e.g. 2 seconds. This action will shut off the device regardless of which mode of operation it is in.
- the device may be configured to automatically shut down when exposed to daylight for a given time, say in excess of 10 minute.
- the device should be able to recharge with the following characteristic: • 36 hours of red, green, or blue usage will be recharged by exposure to full daylight for 8 hours.
- An external charging point and or an auxiliary charge may optionally be provided.
- the device is designed for flat mounting.
- the casing (12) is preferably a hollow injection moulded plastics with a clear non reflective front face and an opaque back housing.
- a range of fastening options may be used and include, without limitation, magnets, hook and loop fasteners, sticky pads, straps, and bolts. Strong magnets are particularly favoured.
- This device is designed specifically to fit as a sleeve over a vehicle antenna but in other respects is similar to the devices of Examples 1 and 2.
- the LED's/ light boxes may be arranged in any variety of configurations, depending on the size and shape of the sleeve.
- the sleeve may be of generally tubular construction in which case the LED's or light boxes may be disposed circumferentially around the tube. Typically, three LED's of each colour will be disposed at say 120° intervals, such that coloured light may be emitted radially in all outwardly directions.
- other shaped sleeves e.g. a boxed construction, different arrangement of LED's will be appropriate.
- the LED'S may be disposed from top to bottom as follows: Top - Blue
- the tube may be an open or closed tube.
- the modes of operation will include: a dim, a bright and an emergency mode of operation and the controls will operate in a similar manner.
- the antennae will be difficult to access so in an alternative embodiment the device may be operated remotely.
- the casing (12) preferably comprises a hollow injection moulded plastics with a clear non reflective outer face and an opaque back housing and is shaped to fit over or around a radio aerial. Preferably, it is light weight.
- Example 4 helmet/ head illuminator
- the illuminators are designed primarily, but not exclusively, to project white light. However, the use of a processor distinguishes them from standard torches.
- the MAMBA has been specifically designed as a personal lighting device which is mounted on a helmet or is attached to the forehead via a strap. Its applications are as:
- the casing (12) has a curvature to ensure a close fit to the helmet or forehead.
- the casing has a maximum size of 90 x 40 x 15 mm
- the LED's are either white (with a movable coloured filter) or are paired so that either white or coloured light may be generated (depending on the requirement).
- the filter or coloured light is green.
- the LED's are arranged in a manner that allows the lighting direction to be carefully controlled for the intended mode of operation.
- the personal lighting device will comprise 8 LED's. Three will be disposed to the left, three to the right and two centrally.
- the two central LED's will be disposed respectively at:
- a switch is provided. Ideally this is provided on the underside (allowing thumb operation) and to the right (the majority users are right handed). Alternatively a double button operation may be preferred.
- Example 1 which ever mode of operation is active when the button is pressed will remain active until the device is powered off.
- the user will hold the button down for a defined period, say 2 seconds. This action will shut off the unit regardless of which mode of operation it is currently in.
- the device may be configured to automatically shut down when exposed to daylight for an excess of 10 minute.
- the battery, LED's and solar panels should be selected and configured to meet the functional requirements of the device, such as:
- the casing (12) is a hollow, injection moulded plastics with a clear non reflective front face and an opaque back housing.
- the rear moulding is curved to accommodate the shape of the head or headgear. Buckles / clips enable the unit to be attached to a webbing strap.
- the mountable torch light has the basic components and functionality of the torch light described with reference to Example 4.
- the main difference lies in the fact that the components (14) are encased in a tubular casing (12) of approximate size 20 mm diameter x 140 mm length and the device has a push button at or towards the end of the tube.
- the device is suitable for hand operation or for mounting on a piece of equipment.
