Abstract
A method is described for deploying one or more illumination devices. The or each illumination device is self-contained and has a first state in which it is inoperative and a second state in which it is operative to provide illumination at at least one frequency within the range from and including infrared to and including ultraviolet. The method comprises the steps, optionally repeated at intervals, of: actuating a mechanism to move a said illumination device from a housing storing one or more illumination devices to an exposed position outside the housing; and automatically changing the state of the illumination device from its first state to its second state as a direct result of movement of the illumination device from within the housing to the exposed position.
Claims20
A method for deploying self-contained illumination devices, each having a first pre-operative state in which it is inoperative but ready for use and a second state in which it is operative to provide illumination at at least one frequency within the range from and including infrared to and including ultraviolet, the method comprising the steps, optionally repeated at intervals, of:
- actuating a mechanism to move a said illumination device from a chamber common to all said devices and located within a housing storing said illumination devices in said first state towards and through a common passage from the housing to an exposed position outside the housing;
- and automatically changing the state of the said illumination device from its first state to its second state as a direct result of and in the course of movement through said common passage.
An illumination device deployment apparatus comprising:
- a housing;
- a plurality of self-contained illumination devices stored in a common chamber within the housing, each said illumination device having a first pre-operative state in which it is inoperative but ready for use and a second state in which it is operative to provide illumination at at least one frequency within the range from and including infrared to and including ultraviolet, the device being in said first state when within said common chamber;
- a mechanism adapted upon actuation to move a said illumination device from within said common chamber towards and through a common passage from the housing to an exposed position outside the housing which requires illumination;
- and an arming device associated with the said mechanism effective to change the state of the illumination device from its first to its second state as a direct result of an in the course of movement of said illumination device through said common passage from within the housing to the said exposed position.
A method for marking a line or laying a trail, the method comprising deploying at intervals, while following the line or trail, which intervals need not be the same, individual self-contained illumination devices from a common chamber therefor within a housing by movement towards and through a common passage from the housing to the exterior thereof, and automatically arming each such device as a direct result of and in the course of movement through the common passage to provide illumination at at least one frequency within the range from and including infrared to and including ultraviolet.
