Sensor tape for security detection and method of fabrication
First Claim
1. A sensor security detector tape for wrapping around an object to be protected, comprising:
- a material strip having a predetermined width and a predetermined length and first and second ends;
a plurality of separate and parallel electrical signal paths arranged along the predetermined length of the material strip, each signal path having a first end at one end of the predetermined length of the material strip and a second end at the other end of the predetermined length of the material strip and operative in a non-alarm condition to carry a signal;
a first connector coupled to each first end of the plurality of signal paths and connecting adjacent pairs of the first ends of the plurality of signal paths to one another;
a second connector coupled to each second end of the plurality of signal paths and connecting adjacent pairs of the second ends of the plurality of signal paths to one another;
wherein the connected pairs of first ends and second ends by the first and second connectors, respectively, establish a single continuous electrical signal path;
the first connector operative to couple an electrical signal from a signal source for transmission over the single continuous signal path;
the second connector operative to couple the electrical signal transmitted over the single continuous signal path to a signal detector; and
wherein a break in any of the signal paths causes a loss of the electrical signal transmitted over the single continuous signal path and indicative of an alarm condition.

Abstract
A sensor in the form of an elongated flexible tape has a signal path made from electrical wire or optical fiber which extends between one end and another end of the tape. The electrical wires or optical fibers are disposed in spaced relation across the width and along the length of the tape and are terminated in connectors at the endpoints of the tape. The connectors may be integrated into a signal detector to interface with communication links. The tape is a material that is non-conductive and in which the wires or optical fibers may be woven, disposed or embedded in some manner. One or more layers of flexible material can be laminated on respective sides of the sensor tape to provide a robust laminated or bonded structure that can be rolled and unrolled from a reel. An adhesive layer and a removable layer can be provided to protect the adhesive layer prior to use. An overcoat of outer layer resin may be applied.
