Abstract

The present invention is related to monitoring movement, and in particular to systems and methods for securing a monitoring device to a monitor target.

First claim

What is claimed is:

1. A monitoring system, the monitoring system comprising:
a strap including an optical path having a first end and a second end separated by an opening;
a male connector including a light path distinct from the optical path that when inserted in the opening allows for light to transmit between the first end and the second end of the optical path; and
an interfering element operable to block light transmitted along the optical path when the male connector is not inserted in the opening.

2. The monitoring system of claim 1 , wherein the interfering element is operable to deform to block the optical path when the male connector is not inserted in the opening.

3. The monitoring system of claim 1 , wherein the interfering element is operable to move to block the optical path when no pressure is placed on the interfering element.

4. The monitoring system of claim 1 , wherein a first portion of the interfering element is disposed below the optical path, and a second portion of the interfering element extends upward to block the optical path when no pressure is put on the second portion.

5. The monitoring system of claim 4 , wherein the second portion is compressed downward such that it does not block the optical path when pressure is placed on the second portion.

6. The monitoring system of claim 1 , wherein the monitoring system further comprises:
a buckle operable to connect ends of the strap, wherein the male connector is part of the buckle.

7. The monitoring system of claim 6 , wherein the buckle includes a securing point used to secure the buckle relative to the strap.

8. The monitoring system of claim 1 , wherein the strap includes connectors to connect the strap to a monitoring device.

9. The monitoring system of claim 1 , wherein the interfering element is made of thin sheet metal with spring like characteristics.

10. The monitoring system of claim 1 , wherein the light path is made of a fiber optic material.

11. The monitoring system of claim 1 , wherein the light path has a first light path end and a second light path end, and wherein when the male connector is inserted in the opening, the first light path end contacts the first end of the optical path and the second light path end contacts the second end of the optical path.

12. A method for connecting a monitoring device to a subject, the method comprising:
providing a strap including:
an optical path separated by an opening, wherein the optical path has a first end on a first side of the opening and a second end on a second side of the opening;
a male connector including a fiber optic light path that when inserted in the opening allows light to transmit between the first end and the second end of the optical path;
an interfering element operable to block light transmitted along the optical path when the male connector is not inserted in the opening

aligning ends of the strap to align the opening with a hole;
inserting the male connector into the opening such that:
the fiber optic light path optically connects the first end and the second end of the optical path; and
the male connector moves the interfering element out of the optical path at the opening.

13. The method of claim 12 , wherein the interfering element is made of thin sheet metal with spring like characteristics.

14. The method of claim 12 , wherein the interfering element is operable to deform to block the optical path when the male connector is not inserted in the opening.

15. The method of claim 12 , wherein the interfering element is operable to move to block the optical path when no pressure is placed on the interfering element.

16. The method of 10 , wherein a first portion of the interfering element is disposed below the optical path, and a second portion of the interfering element extends upward to block the optical path when no pressure is put on the second portion.

17. The method of claim 16 , wherein the second portion is compressed downward such that it does not block the optical path when pressure is placed on the second portion.

18. The method of claim 12 , wherein the male connector is part of a buckle, and wherein inserting the male connector into the opening includes installing the male connector relative to the strap.

19. A tamper resistant strap, the strap comprising:
an optical path separated by an opening, wherein two ends of the optical path are exposed at the opening;
a male connector including a light path that when inserted in the opening provides an optical bridge connecting the optical path; and
an interfering element operable to block light transmitted along the optical path when the male connector is not inserted in the opening, wherein a first portion of the interfering element is disposed out of the optical path, and a second portion of the interfering element extends to block the optical path when no pressure is put on the second portion.

20. The strap of claim 19 , wherein the means for blocking is a metal element that compresses under pressure, and does not block the optical path when sufficiently compressed.

21. The strap of claim 19 , wherein the means for blocking is a metal element that extends to block the optical path in the absence of pressure.

22. The strap of claim 19 , the tamper resistant strap further comprises:
a buckle operable to connect ends of the strap, wherein the male connector is part of the buckle, and wherein the buckle includes a securing point used to secure the buckle relative to the strap.

23. A signal transmitting device, the device comprising:
a component including a female connector and an optical path, wherein a first end of the optical path is accessible at a first side of the female connector and a second end of the optical path is accessible at a second side of the female connector;
a male connector including a fiber optic light path separate from the optical path, wherein when the male connector is inserted in the female connector allows for light to transmit between the first end of the optical path and the second end of the optical path; and
an interfering element operable to block light transmitted along the optical path when the male connector is not inserted in the female connector.
