Abstract

A mounting strap assembly of a tracking device includes a primary mounting strap and one more secondary reinforcing support straps. Continuity sensing elements and other tamper detection means detect any attempt to cut through the mounting strap assembly during an attempted removal of the tracking device from an offender or other mounted location. The reinforcing support straps keep the mounting strap assembly from being completely severed while providing authorities time to be summoned to the location where the tracking device is located and prior to the tracking device being completely removed.

Claims

1. A tracking device comprising:

a housing containing circuitry for detecting and communicating a location of the tracking device;

a mounting strap that is connected to the housing and that is configured in size and shape for being securely wrapped around and mounted to a part of a person wearing the tracking device;

a continuity cable that extends along the entire length of the mounting strap and that at least periodically carries a signal through the mounting strap to and from the circuitry in the housing; and

a first hardened metal band that is affixed to a first side of the mounting strap and which provides reinforcing support to the mounting strap.

2. The tracking device recited in claim 1, wherein the tracking device further comprises a second hardened metal band that is affixed to a second side of the mounting strap.

3. The tracking device recited in claim 2, wherein the continuity cable comprises at least one strand of an optical fiber and wherein the signal is an optical signal.

4. The tracking device recited in claim 3, wherein the at least one strand of the optical fiber is positioned between the first and second hardened metal bands.

5. The tracking device recited in claim 4, wherein an attempted severing of the first and second hardened metal bands will apply a crushing force to the at least one strand of the optical fiber that is sufficient to create a discontinuity within the continuity cable and that will effectively prevent the signal from passing through the mounting strap to the circuitry and which will result in the circuitry generating an alarm.

6. The tracking device recited in claim 2, wherein the first and second hardened metal bands are substantially flat.

7. A tracking device comprising:

a housing;

tracking and monitoring circuitry for detecting a location of the tracking device;

communication circuitry for wirelessly communicating the location of the tracking device to a remote monitoring system, the tracking and monitoring circuitry and the communication circuitry being connected to the housing;

a primary mounting strap that is connected to the housing and that is configured in size and shape for being wrapped around an ankle of a person and for securely mounting the tracking device to the person;

at least one secondary strap that is composed of a different material than the primary mounting strap, the at least one secondary strap being composed of a material that is harder to sever with a cutting instrument than a material of the primary mounting strap; and

at least one continuity cable that extends along the entire length of the primary mounting strap and that carries a signal to the tracking and monitoring circuitry, wherein the tracking and monitoring circuitry is configured to detect an alarm condition associated with a discontinuity of the signal consistent with a break of the at least one continuity cable,

wherein the at least one secondary strap is positioned relative to the at least one continuity cable along the primary strap so as to cause the at least one continuity cable to be broken during an attempted severing of the secondary strap.

8. The tracking device recited in claim 7, wherein an attempted severing of the secondary strap causes the at least one continuity cable to be broken and an alarm to be triggered a period of time prior to the at least one secondary strap being completely severed.

9. The tracking device recited in claim 8, wherein the period of time is an amount of time it takes for a responder notified by the alarm to be summoned to and arrive at a location identified by the tracking device.

10. The tracking device recited in claim 9, wherein the alarm is transmitted through a wireless communication to a monitoring center and the responder is notified by the monitoring center of the alarm.

11. The tracking device recited in claim 9, wherein the amount of time is more than 5 minutes.

12. The tracking device recited in claim 7, wherein the primary mounting strap, the at least one secondary strap, and at least one continuity cable are all encased within a protective covering.

13. The tracking device recited in claim 7, wherein the at least one secondary strap comprises at least two metal bands that are placed on opposing sides of the primary mounting strap.

14. The tracking device recited in claim 7, wherein the at least one secondary strap comprises at least two metal bands that are placed on opposing sides of the at least one continuity cable.

15. The tracking device recited in claim 14, wherein the continuity cable comprises a fiber optic strand which is configured to break when forces are applied to the at least one secondary strap in an attempted severing of the at least one secondary strap.

16. A tracking device comprising:

a housing;

tracking and monitoring circuitry for detecting a location of the tracking device;

communication circuitry for wirelessly communicating the location of the tracking device to a remote monitoring system, the tracking and monitoring circuitry and the communication circuitry being contained within the housing;
