Abstract
A signalling device comprising an emission module operative on the application of battery power from a battery pack for the emission of a signal from at least one electromagnetic radiation emitting element, a battery compartment and a cap for retaining said battery pack in said battery compartment. The cap comprises at least one sensor and a switch for controlling the application of battery power. The switch is actuated when the at least one sensor detects a change in the environment in the vicinity of the device. Alternatively, the switch can be actuated remotely through a wireless interface or via a trip wire.
Claims34
A signaling device comprising:
- an emission module operative on the application of battery power from a battery pack and comprising at least one electromagnetic radiation emitting element, an electromagnetic radiation emitting element controller and a multi-position switch for selecting one of a plurality of predetermined control signatures;
- a battery compartment;
- a first cap for retaining said battery pack in said compartment, wherein when said first cap is installed on said compartment said controller illuminates said at least one electromagnetic radiation emitting element according to said selected control signature;
- and
- at least one adaptor cap interchangeable with said first cap, said at least one adaptor cap comprising a second battery powering a second switch for controlling said application of battery power, wherein when said second switch is closed, said controller illuminates said at least one electromagnetic radiation emitting element according to said selected control signature.
