Abstract: A portable electronic device that selectively deploys a liquid incapacitating chemical agent is described. During operation, the portable electronic device receives or provides a trigger signal. For example, the portable electronic device may include a trigger (such as a mechanical or an electronic trigger), and the portable electronic device may provide the trigger signal when the trigger is activated. Alternatively or additionally, the portable electronic device may provide the trigger signal when an individual is detected in proximity or may receive the trigger signal via wireless communication. In response to the trigger signal, a control circuit provides a control signal to a pump. Then, based at least in part on the control signal, the pump transfers the liquid incapacitating chemical agent from a reservoir to a nozzle. Next, the nozzle discharges the liquid incapacitating chemical agent, e.g., in a stream, where the stream is external to the portable electronic device.

Abstract: A composition for deterring intruders includes propionic acid, ammonia and water. A content of water in the composition is at least approximately 60% by weight. A system for spraying a composition comprises a nozzle configured to spray the composition in an area inside a building. The composition comprises propionic acid, ammonia and water. A content of water in the composition is at least approximately 60% by weight.

Abstract: A distracting module system includes a hydro pneumatic solution tank, a valve, a nozzle, a controller and a detecting system. The controller is programmed to receive a sensor alert signal from the detecting system and send an activation signal to the valve to regulate and control fluid movement from the hydro pneumatic solution tank through the valve and to the nozzle, and to deliver information related to the sensor alert signal and the activation signal to third party devices.
