Abstract

A personal item theft deterrent system which sets forth two individual embodiments and one of which relies upon a physical attachment of a personal item to an individual as, for example, through a cord or cable. The other of the embodiments relies upon a wireless and uncoupled alarm responsive system. In the embodiment using a physical attachment, a cord or cable is connected to the personal item and to the individual to whom the personal item belongs by a tether or cord and preferably a decorative cord. A tensioning device which places tension on the cord is incorporated with the cord so that the user can sense someone attempting to move the personal item. In the second embodiment, a transmitter is located in or on the personal item and sends a proximity signal to a receiver located at or with the owner of the person item. When the personal item is moved beyond a pre-selected distance away from the owner, the signal from the transmitter will become weaker and a circuit in a device in the proximity of the owner will cause the generation of an alarm signal.

Claims

1. A device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual, said device comprising:

a) a cord functioning as a tether extending between the item belonging to the individual and the individual; and

b) a cord tensioning affecting device inserted between the individual and the item belonging to the individual which automatically affects the tension on the cord when a tensional force is imposed on the cord.

2. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 1

further characterized in that said cord tension affecting device comprises a spool upon which the cord is wound and which allows for pay-out of said cord when the tensional force is imposed on said cord.

3. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 1

further characterized in that said cord tension affecting device comprises a spool which is biased to increase tension as the cord is pulled.

4. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 1

further characterized in that said cord tension affecting device comprises a spool upon which the cord is wound and which allows for pay-out of said cord when the tensional force is imposed on said cord and means for increasing the tension on the cord as the cord is pulled from the spool.

5. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 1

further characterized in that an alarm is operatively connected to said device to automatically generate an alarm when a tensional force is imposed on said cord.

6. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 1

further characterized in that the cord is attached to the item and to the individual through a wrist band worn about the individual.

7. A device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual, said device comprising:

a) transceiver means for enabling a wireless signal to extend between said item and said individual;

b) means for measuring a level of said wireless signal and determining if said level of said wireless signal represented a distance between said item and said individual which exceeded a certain predetermined distance; and

c) an alarm device initiating an alarm if said distance between the individual and the item exceeded the predetermined distance.

8. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 7

further characterized in that said transceiver means comprises a transmitter at said item or said individual and a receiver at the other of said item or individual.

9. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 7

further characterized in that the means for measuring the level of the wireless signal comprises a receiving amplifier and a threshold detector which receives a threshold signal therefor.

10. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 9

further characterized in that said threshold signal is compared against the input signal from the transmitter and initiates an alarm signal if the threshold exceeded a predetermined level.

11. The device for reducing incidence of theft or forgetful inadvertence of an item belonging to an individual of

claim 10

further characterized in that said alarm generates an audible signal if the distance between the individual and the item exceeded a predetermined distance.

12. A method for reducing the incidence of theft or forgetful inadvertence of an item belonging to an individual, said method comprising:

a) connecting a tether to an individual and to the item belonging to that individual; and

b) applying tension to that tether when the distance between the individual and the item belonging to that individual increases beyond a predetermined threshold level.

13. The method of

claim 12

further characterized in that the method comprises allowing unwinding of said tether from a spool containing same.

14. The method of

claim 12

further characterized when a distance between the item and the individual increases beyond a predetermined distance.

15. A method for reducing the incidence of theft or forgetful inadvertence of an item belonging to an individual, said method comprising:

a) creating a wireless signal between the item and the individual;

b) measuring the level of that wireless signal periodically and determining if the level of that signal represents a distance between the item and the individual which exceeds a predetermined distance; and

c) generating an alarm if the distance between the individual and the item exceeded that predetermined distance.
