Claims
- 1. A personal alarm having an electronic alarm circuit, said alarm circuit being placeable into an ON condition in which an alarm sounds and an OFF condition, said personal alarm further comprising:
- an actuator being manually actuable for placing said alarm circuit into one of said conditions; and
- said alarm circuit including:
- an actuation circuit responsive to manual actuation of said actuator for placing said alarm circuit into said one of said conditions;
- an oscillator for producing an oscillating signal;
- a switch means responsive to said oscillating signal for switching between an OFF state and an ON state;
- an autotransformer responsive to said switch means for providing a stepped up signal generated in accordance with said oscillating signal; and
- an auditory speaker responsive to said stepped-up signal for producing a high-intensity sonic alarm signal having an intensity of at least 105 dB at a distance of 2 feet from said alarm circuit.
- 2. The personal alarm of claim 1 wherein said actuator generates a code signal in response to manual actuation.
- 3. The personal alarm of claim 2 wherein said actuator includes a depressable member, said actuator generating said code signal in response to a sequence of manual depressions of said depressable member.
- 4. The personal alarm of claim 3 wherein said actuator includes a visual display that is responsive to manual depression of said depressable member.
- 5. The personal alarm of claim 1 wherein said actuator is a toggle switch.
- 6. The personal alarm of claim 1 wherein said actuator is a slide switch.
- 7. The personal alarm of claim 1 wherein said actuator is a threshold pressure switch.
- 8. The personal alarm of claim 1 wherein said actuator generates a code upon manual actuation and wherein said actuation circuit monitors said code.
- 9. The personal alarm of claim 1 wherein said one of said conditions is said OFF condition.
- 10. The personal alarm of claim 9 wherein said actuator generates a code signal in response to manual actuation.
- 11. The personal alarm of claim 10 wherein said actuator includes a depressable member, said actuator generating said code signal in response to a sequence of manual depressions of said member.
- 12. The personal alarm of claim 11 wherein said actuator includes a visual display that is responsive to said sequence of manual depressions of said depressable member.
- 13. The personal alarm of claim 9 wherein said actuator is a toggle switch.
- 14. The personal alarm of claim 9 wherein said actuator is a slide switch.
- 15. The personal alarm of claim 9 wherein said actuator is a threshold pressure switch.
- 16. The personal alarm of claim 9 wherein said actuator generates a code upon manual actuation and wherein said actuation circuit monitors said code.
