Abstract
Abstract A remote monitoring system, particularly useful in monitoring the position of a child or Alzheimer's patient, has a first unit including a handheld portable transmitter and receiver; and a second unit including two identical sections, wherein each section is carried in one of a footwear pair, and each section has a transmitter and receiver. The transmitter of the first unit has a selective switch for on-demand transmission of a find signal. The transmitters of the second unit each continuously emits a location signal. The receiver of the first or handheld unit is responsive to one of or both location signals. The handheld unit generates an audible alarm indicating that the person wearing the footwear has gone beyond a preset distance from the first or handheld unit. The receivers of the second unit each receive the find signal generated by the first unit, and in response thereto, actuates a plurality of illuminating devices, such as LEDs in the soles of the footwear as well as actuating an audio alarm from the footwear.

Claim 3
Dependent Claim
44 words
The system according to claim 1, said first and second primary receiver means, each with respective said first and second primary alarm means being integrally formed in each of a pair of footwear apparel, respectively, wherein the footwear is worn by the second carrier.
Claim 4
Dependent Claim
19 words
The system according to claim 2, said demand actuator being switch means; said alarms being audio and visual indicators.
Claim 5
Dependent Claim
115 words
The system according to claim 1, further comprising: first and second secondary transmitter means coupled to the second carrier, each continuously generating a location signal; secondary receiver means coupled to the first carrier for receiving any one of said first secondary transmitter location signal, said second secondary transmitter location signal, and both said first and second secondary transmitter location signals, and generating a secondary alarm signal in response thereto when the received signals indicate said boundary limits have been exceeded; and secondary alarm means for generating an audio alarm indicative of the received location signals, said audio alarm of said secondary alarm means being representative that the second carrier has exceeded said predetermined boundary limits.
Claim 6
Dependent Claim
40 words
A system according to claim 4, further comprising: first adjustment means for selectively establishing the range of the predetermined boundary limit; and second adjustment means for selectively establishing the volume level of said audio alarm of said secondary alarm means.
Claim 7
Dependent Claim
257 words
A radio frequency communication system between at least two persons for remote signalling when one of the persons exceeds a predetermined boundary limit comprising: first housing means carried by the first person having: primary transmitter means for emanating a find signal, having a demand actuator for selectively causing said find signal to emanate; secondary receiver means for receiving any one of a first secondary transmitter location signal, a second secondary transmitter location signal, and both said first and second secondary transmitter location signals, and generating a secondary alarm signal in response thereto when the received signals indicate said boundary limits have been exceeded; and secondary alarm means for generating an audio alarm responsive to said secondary alarm signal; second housing means worn by the second person having: first and second primary receiver means for receiving said find signal emanated from said primary transmitter means and for generating a primary alarm signal in response to said received find signal; first and second primary alarm means respectively coupled to said first and second primary receiver means, each receiving said respective alarm signal and each generating a respective alarm in response thereto; first and second secondary transmitter means each continuously generating a location signal, whereby said first primary receiver means, said first primary alarm means, and said first secondary transmitter are integrally contained in a first shoe worn by the second person; and said second primary receiver means, said second primary alarm means, and said second secondary transmitter are integrally contained in a second shoe worn by the second person.
Claim 8
Dependent Claim
