Wireless battery compartment adapter cap for control of electric power and device equipped therewith

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 a wireless receiver operationally connected to a switch for controlling the application of battery power.

1 . A signalling device comprising:
 a battery pack;   an emission module operative on the application of battery power and comprising at least one light emitting element, a light emitting element controller and a multi-position switch for selecting one of a plurality of predetermined control signatures;   a battery compartment; and   a battery compartment cap comprising a wireless receiver and a switch for controlling said application of battery power;   wherein said switch is actuated on reception of a wireless signal and further wherein when said switch is closed, said controller illuminates said at least one illuminating element according to said selected control signature.   
   
   
       2 . The device of  claim 1 , wherein said wireless receiver comprises an RF receiver and said transmitter comprises an RF transmitter. 
   
   
       3 . The device of  claim 1 , wherein said wireless receiver comprises an infra red receiver and said transmitter comprises an infra-red transmitter. 
   
   
       4 . The device of  claim 1 , wherein said at least one light emitting element emits visible light. 
   
   
       5 . The device of  claim 1 , wherein said at least one light emitting element emits infra-red light. 
   
   
       6 . The device of  claim 1 , wherein said multi-position switch is a rotary switch. 
   
   
       7 . A cap for retaining a battery pack in a battery compartment of a device operative on the application of battery power for the emission of light from at least one light emitting element, the cap comprising:
 a wireless receiver; and   an electronic switch for controlling said application of battery power, wherein said switch is actuated when said receiver receives a wireless signal from a transmitter.   
   
   
       8 . The device of  claim 7 , wherein said wireless receiver comprises an RF receiver and said transmitter comprises an RF transmitter. 
   
   
       9 . The device of  claim 7 , wherein said wireless receiver comprises an infra red receiver and said transmitter comprises an infra-red transmitter.
