ABSTRACT:
A personal safety alarm device, including a main housing, and a light source maintained within the housing. An audio alarm speaker is located on an outside surface of the housing, along with a pair of high voltage electrodes located on the top surface of the main housing. In addition, the device features a timekeeping device including a DC powered oscillator, memory unit, and associated display device therewith. There is a high voltage generating circuit within the housing which is coupled to the electrodes. Finally, an alarm triggering circuit has an alarm switch which, when activated, causes both the light source to flash intermittently and the audio alarm speaker to sound intermittently. The high voltage generating circuit produces, at the pair of high voltage electrodes, a voltage capable of delivering a stunning electric shock to an assailant. Electric power to the oscillator is interrupted whenever said alarm switch is activated, thereby "recording" the time of such activation, and this time is still displayed since the memory unit of the timekeeping device is supplied with DC power independently from the oscillator.
