Abstract
An apparatus includes a sensor assembly. The sensor assembly includes a transmission-line assembly having an electrical transmission-line parameter configured to change, at least in part, in response to reception, at least in part, of a vehicular load of a moving vehicle moving relative to a vehicular roadway to the transmission-line assembly positionable, at least in part, relative to the vehicular roadway.
Claims16
A sensor, comprising:
- a force receiving element with a first surface for receiving a force and a second flat surface;
- a deformable element connected to the force receiving element and a flat strip;
- a gap defined by the distance between the second flat surface and the flat strip;
- wherein, when a force is applied to the first surface, the gap between the second surface and the flat strip decreases;
- and
- wherein, the sensor has a reflection coefficient that varies linearly with respect to the force applied to the force receiving element, the deformable element, or both.

A transmission line, comprising:
- a force receiving element with a first surface for receiving a force and a second flat surface;
- a deformable element connected to the force receiving element and a flat strip;
- a gap defined by the distance between the second flat surface and the flat strip, the gap defining an impedance of the transmission line;
- wherein, when a force is applied to the first surface, the gap between the second surface and the flat strip decreases
- wherein, the transmission line has a reflection coefficient that varies linearly with respect to the force applied to the force receiving element, the deformable element, or both.
