Abstract
The present invention relates to a contact sensor that detects contact between two objects and includes a first conductor separated from a second conductor by a crushable layer with a predetermined crush resistance. The crushable layer deforms under pressure such that a signal passes between the first and second conductor. Methods of detecting contact are also part of this invention
Claims18
A sensor comprising:
- a cable comprising:
- a first conductor, a second conductor, and an extruded crushable layer located between the first and second conductors;
- a signal generator connected to the first conductor;
- and
- a signal detector connected to the second conductor,
- wherein the first and second conductors are adapted to touch and pass a signal from the signal generator to the signal detector upon deformation of the crushable layer.
3 more elements
A device comprising:
- a cable comprising a first conductor;
- a second conductor;
- and an extruded crushable layer located between said first and second conductors, wherein the first and second conductors are coaxial and the crushable layer is adapted to permit the first and second conductors to touch and to pass a signal upon the deformation of the crushable layer.
A method of sensing contact between two objects, comprising:
- generating a signal on a first conductor;
- deforming an extruded crushable layer separating the first conductor from a second conductor;
- and
- detecting the signal on the second conductor when the conductors touch.
1 more element
A method of manufacturing a sensor, comprising:
- extruding a crushable material onto a first conductor;
- and
- covering the extruded crushable material with a second conductor,
- wherein the crushable material is adapted to permit the first and second conductors to touch.
