Abstract

A system for tracking as lost child a receiver attached to the coupled to a small child. The system comprises a transmitter carried by the parent. A small receiver and activator is attached to the child. When the parent activates the transmitter, the receiver is activated and buzzer or beeper is set off.

Claims

1. A child locator system comprising:

a first unit consisting essentially of;

a retaining means;

a receiver for receiving a signal from a transmitter;

an alert means for producing an alarm;

a first identification module for enabling communication using a unique digital binary signature;

a first proximity device that communicates with a second proximity device to indicate when the first unit has exceeded a predetermined distance from a second unit;

a first power supply; and

an on/off switch,

wherein said receiver, said first identification module and said first proximity sensor are operatively associated with one another to produce or receive a signal, wherein said first unit is an article worn by children or a child'"'"'s adornment having a shape and wherein said shape is selected from the group consisting of an animal figure, a toy, a ball, a doll and a car; and

said second unit consisting essentially of;

said transmitter for transmitting a signal to said receiver;

an activating button for triggering said alert means;

a second power supply;

said second proximity device that communicates with said first proximity device to indicate when the first unit has exceeded a predetermined distance from the second unit; and

a second identification module for enabling communication with the first unit using said unique digital binary signature,

wherein said transmitter, said second identification module and said second proximity sensor are operatively associated with one another to produce or receive a signal.

2. The child locator system of claim 1, wherein said retaining means is selected from the group consisting of:

a chain, a zipper, fabric, buttons, snaps, clasps and lace.

3. The child locator system of claim 1, wherein said second unit is a portable, hand held, water resistant device capable of being attached to a key chain.

4. The child locator system of claim 1, further comprising a time delay module adapted to be used with either said first unit or said second unit.

5. The child locator system of claim 1, further comprising a battery level indicator adapted to be used with either said first unit or said second unit.

6. The child locator system of claim 5, further comprising a voltage regulator adapted to be used with said second unit.

7. The child locator system of claim 1, wherein said first unit is a child'"'"'s adornment having a shape and wherein said shape is an animal figure.

8. The child locator system of claim 1, further comprising a second on/off switch adapted to be used with the second unit.

9. A child locator system comprising:

a first unit, first unit consists essentially of;

a receiver for receiving a signal from a transmitter;

an alert means for producing an alarm;

a first antenna;

a first power supply;

a retaining means for retaining said first unit proximate to a child;

a first identification module for enabling communication using a unique digital binary signature, wherein said first identification module is operatively associated with said receiver; and

an on/off switch,

wherein said first unit is an article worn by children or a child'"'"'s adornment having a shape, and wherein said shape is selected from the group consisting of an animal figure, a toy, a ball, a doll and a car; and

a second unit consisting essentially of;

said transmitter for transmitting to said receiver;

an activating button for triggering said alert means;

a second antenna;

a second power supply; and

a second identification module for enabling communication with first unit using said unique digital binary signature, wherein said second identification module is operatively associated with said transmitter.

10. The child locator system of claim 9, further comprising a time de1ay module adapted to be used with either said first unit or said second unit.

11. The child locator system of claim 9, further comprising a battery level indicator adapted to be used with either said first unit or said second unit.

12. The child locator system of claim 11, further comprising a voltage regulator adapted to be used with said second unit.

13. The child locator system of claim 9, wherein said first unit is a child'"'"'s adornment having a shape and wherein said shape is an animal figure.

14. The child locator system of claim 9, wherein said second unit is a portable, hand held and water resistant device capable of being attached to a key chain.

15. The child locator system of claim 9, further comprising:

a first proximity device adapted to be used with the first unit and

a second proximity device adapted to be used with the second unit, wherein said first proximity device communicates with said second proximity device to indicate when said first unit has exceeded a predetermined distance from said second unit.
