Personal safety guard system for stray person or pet
First Claim
1. A personal safety guard system for enhancing the safety of a person or pet under the care of a guardian in an unconfined environment, comprising:
- a guardian unit including;
a first housing constructed to be carried by a guardian having care of a person or a pet,alarm signal means contained in said first housing, for producing an alarm condition signal at a certain radio frequency,first antenna means for radiating said alarm condition signal over a certain range when coupled to an output of said alarm signal means, andtransmit switch means coupled to said alarm signal means, for operating said alarm signal means to produce the alarm condition signal in response to an alarm command entered by the guardian, andan alarm unit including;
a second housing constructed to be worn by said person or said pet,alarm receiver means contained in said second housing for detecting said alarm condition signal and for producing a corresponding alarm set signal,second antenna means coupled to an input of said alarm receiver means for responding to the alarm condition signal radiated from said first antenna means,speech circuit means for emitting a voice message prior to arrival of the guardian, including means for sounding said voice message to persons other than said guardian near the person or pet wearing the alarm unit, the voice message informing said persons that the person or pet is under a guardian'"'"'s care and needs to be kept from potential harm until said guardian arrives, andalarm control means coupled to an output of said alarm receiver means and to said speech circuit means, for operating said speech circuit means to emit said voice message in response to said alarm set signal produced by the alarm receiver means;
wherein the alarm unit remains in a receive only mode of operation and the sounding means of said speech circuit means is inoperative prior to detection by the alarm receiver means of the alarm condition signal radiated from the first antenna means of the guardian unit.

Abstract
A personal safety guard system enables a guardian or caretaker of a person or pet to transmit an alarm condition signal from a hand-held unit carried by the guardian. When the alarm condition signal is received by a portable alarm unit adapted to be worn by the person or pet under the guardian'"'"'s supervision, the alarm unit operates to alert the wearer that its guardian is looking for them, and to alert others nearby that the wearer is in need of assistance by producing a number of different alarm indicators. The alarm indicators produced by the portable alarm unit include an intelligible voice message such as "Help, I'"'"'m lost" which is alternately sounded with a loud alarm sound, and flashing strobe lights. These alarm indicators, together with a confirmation signal transmitted from the alarm unit to the guardian'"'"'s unit, enable the guardian to track and find their charge.
