Actuator for a personal protective spray canister
First Claim
1. An actuator for a personal protective spray canister having a container means for holding a pressurized protective material capable of being propelled in a gaseous cloud to at least partially disable a person and a manipulative valving device protruding outwardly from said container means, with said valving device having an outlet for directing said gaseous cloud from said container means and a valve element movable between a first biased normal position closing said outlet and a second depressed operative position opening said outlet to allow said material to be propelled from said container means as said cloud, said actuator comprising:
- a radio frequency receiver means for detecting and receiving a coded radio frequency signal, a decoder means for creating an identification signal when said receiver means receives a radio frequency signal with a preselected code, mechanical means for moving said valve element into said second depressed, operative position in response to a danger signal, means for creating said danger signal in response to a given number of identification signals received within a given time, electrical means for providing power to operate said mechanical means to depress said valve element and means for mounting said actuator onto said container with said mechanical means operatively associated with said valve element.

Abstract
An actuator for a personal protective spray canister having a container for holding a pressurized protective material capable of being propelled in a gaseous cloud to at least partially disable a person and a manipulative valving device protruding outwardly from the container, with the valving device having an outlet for directing the gaseous cloud from the container, and a valve element movable between a first biased normal position closing the outlet and a second depressed operative position opening the outlet to allow the material to be propelled from the container as a cloud. The actuator comprising: a radio frequency receiver for detecting and receiving a coded radio frequency signal, a decoder for creating an identification signal when the receiver receives a radio frequency signal with a preselected code, a mechanical device for moving the valve element into the second depressed, operative position in response to a danger signal, a circuit for creating a danger signal in response to a given number of identification signals, a power supply for providing power to operate the mechanical device to depress the valve element when the actuator is operatively associated with the valve element of the container.
