Personal security alarm

Claim 2

A security alarm for an individual comprising: a hand unit including transmitter means, actuating means operative to cause said transmitter means to produce a radio-frequency signal, and first attachment means for positioning said actuating means proximate the palm of a hand of said individual such that when said individual clenches said hand transmitter means is activated;

Claim 3

a torso unit including receiver means, alarm means responsive to said receiver means and operative to produce an audible alarm, and second attachment means for positioning said torso unit proximate the torso of said individual.

Claim 4

Claim 5

A security alarm as recited in claim 1 wherein said actuating means comprises a power supply, and switch means for coupling said power supply to said transmitter means.

Claim 6

A security alarm as recited in claim 2 wherein said hand unit further includes a housing for said transmitter means, switch means, and power supply, and wherein said first attachment means includes a strap attached to said housing adapted to encircle said individual's hand and hold said housing against said individual's palm.

Claim 7

A security alarm as recited in claim 3 wherein said housing is contoured to fit said individual's palm.

Claim 8

A security alarm as recited in claim 4 wherein said switch means includes an actuator button which extends substantially the entire length of said housing.

Claim 9

A security alarm as recited in claim 1 wherein said actuating means comprises a mechanical-to-electrical transducer.

Claim 10

A security alarm as recited in claim 6 wherein said mechanical-to-electrical transducer includes generator means having a permanent magnet and a coil.

Claim 11

A security alarm as recited in claim 6 wherein said mechanical-to-electrical transducer includes a piezoelectric device.

Claim 12

A security alarm as recited in claim 6 wherein said hand unit further includes a housing for said transmitter means, switch means, and power supply, and wherein said first attachment means includes a strap attached to said housing adapted to encircle said individual's hand and hold said housing against said individual's palm.

Claim 13

A security alarm as recited in claim 9 wherein said housing is contoured to fit said individual's palm.

Claim 14

A security alarm as recited in claim 10 wherein said switch means includes an actuator button which extends substantially the entire length of said housing.

Claim 15

A security alarm as recited in claim 1 wherein said torso unit further includes latching means responsive to said receiver means and operative to activate said alarm means.

Claim 16

A security alarm as recited in claim 12 wherein said latching means includes reset means operative to disable said latching means.

Claim 17

A security alarm as recited in claim 13 wherein said torso unit includes a housing, and wherein said reset means is activated by extending an elongated member through an aperture provided in said housing to contact a switch located within said housing.

Claim 18

A security alarm as recite in claim 14 wherein said second attachment means includes means for attaching said housing proximate to the waist of said individual.

Claim 19

A personal security alarm comprising: short range transmitter means responsive to an actuating signal and operative to produce a radio frequency signal; actuator means adapted to be strapped to a user's hand, said actuator means being operative to produce said actuating signal in response to mechanical pressure exerted by said hand; short range receiver means responsive to said radio frequency signal and operative to produce a detection signal; latch means responsive to said detection signal and a reset signal and operative to produce a latched signal; and alarm means responsive to said latched signal and operative to produce an audible alarm signal, said alarm means being adapted to attach proximate the torso of said user.

Claim 20

A personal security alarm comprising: short range transmitter means responsive to an actuating signal and operative to produce a radio frequency signal; actuator means adapted to be strapped to a user's hand, said actuator means being operative to produce said actuating signal in response to mechanical pressure exerted by said hand; short range receiver means responsive to said radio frequency signal and operative to produce a detection signal; latch means responsive to said detection signal and a reset signal and operative to produce a latched signal; and alarm means responsive to said latched signal and operative to produce an audible alarm signal, said alarm means being adapted to attach proximate the torso of said user.

Claim 21

A personal security alarm as recited in claim 16 wherein said actuator means includes a power supply and a switch.

Claim 22

A personal security alarm as recited in claim 16 wherein said actuator means includes a mechanical-to-electrical transducer.

Claim 23

A personal security alarm as recited in claim 16 wherein said reset signal is developed by a hidden switch.
