Abstract
Abstract Two embodiments of a triboelectric transducer cable for generating a signal in response to movement or deformation of the cable each include multiple insulated central conductors, a semi-conductive wrapping separately surrounding each of the insulated central conductors with an additional conductor arranged in electrically conductive contact with the semi-conductive wrapping and a protective jacket surrounding the cable assembly.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
A triboelectric transducer cable for generating a signal in response to movement or deformation thereof, comprising a pair of insulated central conductors, a semi-conductive element independently wrapped in physically separate and surrounding relation to each of the insulated central conductors, an additional drain wire conductor arranged in electrically conductive contact with the semi-conductive element, said semi-conductive element being unbonded to the insulated central conductors, a conductive shield means surrounding the drain wire conductor and the semi-conductive lazer element and being in electrical contact therewith, and a protective jacket surrounding the insulated central conductors, semi-conductive element, drain wire conductor and shield means of the cable.
Claim 2
Dependent Claim
104 words
A triboelectric transducer cable for generating a signal in response to movement or deformation thereof, comprising a pair of insulated central conductors, a semi-conductive element independently wrapped in physically separate and surrounding relation to each of the insulated central conductors, an additional drain wire conductor arranged in electrically conductive contact with the semi-conductive element, said semi-conductive element being unbonded to the insulated central conductors, a conductive shield means surrounding the drain wire conductor and the semi-conductive lazer element and being in electrical contact therewith, and a protective jacket surrounding the insulated central conductors, semi-conductive element, drain wire conductor and shield means of the cable.
Claim 3
Dependent Claim
30 words
The triboelectric transducer cable of claim 1 wherein the shield element is wrapped around the semi-conductive element, the drain wire conductor being arranged between the semi-conductive element and shield element.
Claim 4
Dependent Claim
35 words
The triboelectric transducer cable of claim 2 wherein the shield element is formed from a plastic having a conductive metallic surface arranged in electrically conductive contact with the drain wire conductor and the semi-conductive element.
Claim 5
Dependent Claim
29 words
The triboelectric transducer cable of claim 3 wherein the insulation for each of the central conductors is a dielectric plastic tube, the semi-conductive element being a carbon-embedded nylon tape.
Claim 6
Dependent Claim
24 words
The triboelectric transducer cable of claim 4 wherein the semi-conductive element is wrapped in a figure-eight configuration about the pair of insulated central conductors.
Claim 7
Dependent Claim
24 words
The triboelectric transducer cable of claim 1 wherein the semi-conductive element is wrapped in a figure-eight configuration about the pair of insulated central conductors.
Claim 8
Dependent Claim
31 words
The triboelectric transducer cable of claim 6 wherein the insulation for each of the central conductors is a dielectric plastic tube, the semi-conductive element being formed as a carbon-embedded nylon tape.
Claim 9
Dependent Claim
31 words
The triboelectric transducer cable of claim 1 further comprising an additional insulated central conductor also independently surrounded by the semi-conductive element arranged in electrically conductive relation with the drain wire conductor.
Claim 10
Dependent Claim
43 words
The triboelectric transducer cable of claim 8 wherein the semi-conductive element is formed by three separate wrappings for the respective insulated central conductors, the additional drain wire conductor being in electrically conductive contact with the semi-conductive wrappings for the three insulated central conductors.
