Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A personal safety alarm device, comprising: a main housing; a light source included within the housing; an audio alarm speaker disposed on an outside surface of the housing; a timekeeping device and associated display therewith, said display located on the outside surface of the main housing; and an alarm triggering circuit which further comprises an alarm switch, said switch, when activated, causing said audio alarm speaker to sound intermittently, and further causing said light source to flash intermittently; with said timekeeping device being deactivated whenever said alarm switch is activated, and said display associated with said timekeeping device remaining activated, thereby displaying the time which said alarm switch is activated.
Claim 2
Dependent Claim
110 words
A personal safety alarm device, comprising: a main housing; a light source included within the housing; an audio alarm speaker disposed on an outside surface of the housing; a timekeeping device and associated display therewith, said display located on the outside surface of the main housing; and an alarm triggering circuit which further comprises an alarm switch, said switch, when activated, causing said audio alarm speaker to sound intermittently, and further causing said light source to flash intermittently; with said timekeeping device being deactivated whenever said alarm switch is activated, and said display associated with said timekeeping device remaining activated, thereby displaying the time which said alarm switch is activated.
Claim 3
Dependent Claim
68 words
The personal safety alarm device as described in claim 1, wherein said timekeeping device further comprises: an oscillating device coupled to a DC power source; a memory device having an input coupled to the output of said oscillating device; and said display device connected to the output of said memory device; said memory device further being directly connected to said DC power source, independently from said oscillating device.
Claim 4
Dependent Claim
123 words
A personal safety alarm device, comprising: a main housing; a light source maintained within said housing; an audio alarm speaker on an outside surface of said housing; a timekeeping device comprising a DC powered oscillator, memory unit, and associated display device therewith; a pair of high voltage electrodes located on a top surface of said main housing; a high voltage generating circuit within said housing which is coupled to said electrodes; and an alarm triggering circuit comprising an alarm switch which, when activated, causes: said light source to flash intermittently; said audio alarm speaker to sound intermittently; said high voltage generating circuit to produce, at said pair of high voltage electrodes, a voltage capable of delivering a stunning electric shock to an assailant.
Claim 5
Dependent Claim
123 words
A personal safety alarm device, comprising: a main housing; a light source maintained within said housing; an audio alarm speaker on an outside surface of said housing; a timekeeping device comprising a DC powered oscillator, memory unit, and associated display device therewith; a pair of high voltage electrodes located on a top surface of said main housing; a high voltage generating circuit within said housing which is coupled to said electrodes; and an alarm triggering circuit comprising an alarm switch which, when activated, causes: said light source to flash intermittently; said audio alarm speaker to sound intermittently; said high voltage generating circuit to produce, at said pair of high voltage electrodes, a voltage capable of delivering a stunning electric shock to an assailant.
Claim 6
Dependent Claim
23 words
The personal safety alarm device as described in claim 3, wherein power to said oscillator is interrupted whenever said alarm switch is activated.
Claim 7
Dependent Claim
27 words
The personal safety alarm device as described in claim 4, wherein said memory unit of said timekeeping device is supplied with DC power independently from said oscillator.
