Abstract: A system for spraying, according to various aspects of the present invention, includes a power switch, an arm switch, a trigger switch, and a communication switch. The system establishes a communication link in response to power being applied through the power switch. Before operation of the arm switch, the system establishes a communication link. After operation of the arm switch, the trigger switch activates release of spray. In further response to the trigger switch, the system transmits a notice via the communication link. Such a system when equipped with pepper spray aerosol is advantageous for self-defense.

Abstract: A system for spraying, according to various aspects of the present invention, includes a shuttle and a trigger switch. The shuttle and the trigger switch cooperate with discontinuous mechanical coupling. The trigger switch provides a discontinuity in bias against operation of the trigger switch by the user. Consequently, the user experiences tactile feedback before spray is released. Prior to tactile feedback, the system establishes a communication link. When spray is released, the system transmits a notice via the communication link. Such a system when equipped with pepper spray aerosol is advantageous for self-defense.

Abstract: A security device paired with a user's cell phone is operable by either a trigger or an accelerometer. The device includes visual and audio alarms, a prerecorded message and an audio recording of the ambient noise. Depression of the trigger will spray mace onto an attacker, activate the alarms and alternately send the message and recording to 9-1-1 or other security monitor. Alternatively, the accelerometer will so activate the device. The alarms and transmissions are synchronized so as to not interfere one with the other. Direct communication with 9-1-1 via the Bluetooth®/cell phone interface is immediately established either by a push-to-talk button or at the termination of a predetermined alarm and message transmission period.
