  • the energy store 104 is configured such that it can provide sufficient energy to features of the flash device 100 including, but not limited to, the first light emission unit 108a and the second light emission unit 108b thus enabling the first light emission unit 108a and second light emission unit 108b to emit a respective first optical output 114a and second optical output 114b in order to disorientate a target for a required period of time.

  • the inertial sensor identifies the orientation of the flash device 100 and the proximity sensor determines the proximity of the flash device 100 relative to surfaces such as floors, walls or other objects on which the flash device 100 is in contact with or in close proximity to.
  • the flash device 100 further comprises a processor 106 arranged to receive information from the sensor unit 110 in order to configure the first light emission unit 108a and the second light emission unit 108b and hence control the emission characteristics of the first optical output 114a and second optical output 114b in said plurality of regions of an environment.

  • FIG. 1 Referring to Figure 1 together with Figures 2a, 2b and 2c a flash device 200 similar to that in Figure 1 is shown in use.
  • the flash device 200 of Figures 2a, 2b and 2c has a first light emission unit 208a and second light emission unit 208b and further light emission units 208c, 208d, 208e, 208f.
  • Each of the first light emission unit 208a, second light emission unit 208b and further light emission units 208c, 208d, 208e, 208f are arranged around the surface of the housing 102 of the flash device 200 such that the aforementioned light emission units 208a-f emit a respective first optical output 214a, a second optical output 214b and further optical outputs 214c, 214d, 214e, 214f from the flash device 200 as required.
  • the flash device 200 is activated by engaging an activation switch 118. In other example embodiments the flash device 200 may be activated remotely or by removing a safety device such as a pin or tag, or by being removed from a charging unit or housing.
  • the user deploys the flash device 200 into the environment in which it is to be utilised.
  • the sensor unit 210 captures real-time environment information 116 which in this embodiment is the orientation of the flash device 200 and the proximity of the flash device 200 to objects and surfaces such as walls and floors.
  • This environment information 116 is used by the processor 206 together with the known geometry of the flash device 200 to generate an emission profile which determines whether the aforementioned light emission units 208a-f are instructed to output their respective first optical output 214a second optical output 214b and further optical outputs 214c-f.
  • the flash device 200 has been deployed into the environment in which it is to be utilised and the sensor unit 210 has captured real-time environment information 116 which includes information from the proximity sensor that shows that the flash device 200 is not in close proximity to surfaces such as walls and the floor. Therefore, in this embodiment the emission profile generated by the processor 206 results in the first light emission unit 208a, second light emission unit 208b and further light emission units 208c-f outputting their respective first optical output 214a, second optical output 214b and further optical outputs 214c-f. These optical outputs 214a-f in turn disorientate any targets within the range of the optical outputs 214a-f.
  • the light emission units 208a-f have an optical output beam divergence of ⁇ 120deg full width half max (FWHM) with each optical output 214a-f overlapping, in the far field, with its adjacent optical outputs 214a-f. This ensures that the intensity of optical output 214a-f of the flash device 200 is uniform with angle.
  • FWHM full width half max
  • Figure 2b shows the flash device 200 is in contact with a surface 222 and in close proximity to a wall 224.
  • the sensor unit 210 again captures real-time environment information 116 which indicates that the flash device 200 is in close proximity to the wall 224 and the surface 222.
  • the real-time environment information 116 is used by the processor 206 to determine that the further light emission units 208c-208f will not emit an optical output as they are obstructed.
  • the processor 206 generates a second emission profile which only activates the first light emission unit 208a and second light emission unit 208b. Therefore, energy stored in the energy store 204 will not be used to power further light emission units 208c-f, which do not contribute to the disorientation of a target. This means that the flash device 200 will be able to operate for longer than would be the case if all the light emission units 208a-f were activated.
  • Figure 2c shows the flash device 200 has moved away from the wall 224 but is still in close proximity to the surface 222.
  • the sensor unit 210 again captures real-time environment information 116 which is transmitted to the processor 206 which generates a third emission profile as light emission unit 208f is no longer obstructed. Therefore, the first light emission unit 208a, second light emission unit 208b and further light emission unit 208f can output their respective first optical output 214a, second optical output 214b and further optical output 214f to disorientate any targets in the environment. Due to the proximity of the surface 222 further light emission units 208c-e will not output their respective further optical outputs 214c-e.
  • energy stored in the energy store 204 will not be used to power further light emission units 208c-e which are not going to contribute to the disorientation of a target, and the flash device 200 will be able to operate for longer than would be the case if all the light emission units 208a-f were activated.
  • the optimisation of the optical output of the flash device 200 based on the real-time environment information 116 transmitted from the sensor 210 to the processor 206 ensures the energy store 204 maintains the optical output of the flash device 200 for longer than if all the light emission units 208a-f were outputting their respective optical outputs 214a-f continuously.

  • a unique signature is not detected by a second sensor 310b or a third sensor 310c in the flash device thus further enabling the flash device 300 to determine the likely position of the friendly person 330a in relation to the flash device.
  • exploratory signals 326b, 326c are transmitted such that they could be detected by additional optical tags worn by other people 330b, 330c, further unique signatures are not detected by the sensors 310a, 310b, 310c as there are no other optical tags in the vicinity of the flash device 300.

  • the flash device 300 does activate a second light emission unit 308b which covers the second region 340b of the environment occupied by the other person 330b and activates a third light emission unit 308c which covers the third region 340c of the environment occupied by further person 330c, such that they output an optical output which distracts and disorients the other person 330b and further person 330c degrading their ability to act due to dazzle and/or inducing flash blindness.

  • the flash device 500 has been activated in an environment comprising a number of people 530a, 530b, 530c two of which are hostile.
  • Many features of the flash device 500 operate in the same way as the flash deice 300 of figures 3a , 3b and 3c , however, the flash device 500 differs in that the sensors 510a, 510b, 510c comprise filters (not shown) which detect a reflection of the exploratory optical signal 526b, 526c in the second region 540b and third region 540c which indicate the use of protective eyewear.
  • the flash device 500 changes the wavelength of the optical output provided by the second light emission unit 508b in the second region 540b and optical output provided by the third light emission unit 508c in third region 540c in order to reduce the effectiveness of the protective eyewear, thereby ensuring that the potentially hostile people 530b, 530c are dazzled, disoriented and disabled.

  • Each of the light emission units may comprise single or multiple filters which enable the LEDs, laser diodes and/or supercontinuum white light lasers to emit an optical output across a selective number of different wavelengths.
  • Alternative embodiments of the above example flash devices may be arranged to adjust the beam divergence, range and intensity of the optical output depending on the nature of the potentially hostile target. For example a potentially hostile vehicle may be targeted with a larger beam divergence than a potentially hostile individual. The beam divergence may be adjusted using conditioning optics applied to individual or groups of light emission units. The beam range may also be adjusted together with the threshold of the sensors so that certain types of target are dazzled, disoriented and disabled at different distances away from the flash device. For example, flash devices may activate in the direction of vehicles earlier than for people on foot. Alternatively the above example flash devices may activate a greater number of light emission units for different types of target, thus creating a broader optical output.
