Abstract
A capacitive sensor having a first and a second polymeric conductor are embedded within a non conducting body, wherein the body maintains a fixed separation distance between the first and the second polymeric conductor. The body can include a non conducting web, wherein the web substantially precludes variation in the spacing of the polymeric conductors during use in the intended operating environment.
Claims32
A capacitive sensor comprising:
- (a) an elongate first polymeric conductor,
- (b) an elongate second polymeric conductor;
- and
- (c) a non conductive web intermediate the first polymeric conductor and the second polymeric conductor to maintain a substantially fixed separation distance between the first and the second polymeric conductor, the web, the first polymeric conductor and the second polymeric conductor embedded within a non conductive polymer.
An elongate capacitive sensor for installation about an opening in a motor vehicle, the opening having at least one corner, the sensor comprising:
- (a) a one-piece extruded non conducting body;
- and
- (b) a first polymeric conductor and a second polymeric conductor embedded in the body,
- the body configured to substantially maintain a nominal separation distance between the first polymeric conductor and the second polymeric conductor after installation about the corner.
A capacitive sensor, comprising a polymeric conductor embedded within a non conductive polymeric body, a cross sectional periphery of the polymeric conductor substantially defined by the body.
A method manufacturing a capacitive sensor for installation about a motor vehicle opening having at least one corner, the method comprising forming a non conductive web intermediate a first polymeric conductor and a second polymeric conductor to define a separation distance between the first and the second polymeric conductor, the web configured to substantially maintain the separation distance upon installation about the corner.
A capacitive sensor comprising:
- (a) an elongate first polymeric conductor,
- (b) an elongate second polymeric conductor;
- and
- (c) a non conductive web intermediate the first and the second polymeric conductor, the web and the first and the second polymeric conductor defining a radius of curvature and the web maintaining a substantially fixed separation distance between the first and the second polymeric conductor along the radius of curvature.
