Abstract
A controller for sensing interior motion includes a sensor structure having transmitting conductors and receiving conductors. The controller comprises circuitry to drive and sense signals on interacting pairs of conductors (the transmitting conductor or receiving conductor can act as the drive side, or as the sense side). Signals are processed to analyze changes in measured signal and analyzed to determine interior movement. When the controller is deployed proximate to human skin, movement of muscles, tendons and bones within the skin are reflected in the measured signals.
Claims20
An apparatus comprising:
- a transmitting conductor adapted to transmit signals;
- a receiving conductor adapted to receive signals transmitted by the transmitting conductor;
- the transmitting conductor and the receiving conductor operatively coupled to drive and sense circuitry, the drive and sense circuitry being adapted to cause the transmitting conductor and the receiving conductor to form an interacting pair of conductors, and to measure the interactions between the interacting pair of conductors during a plurality of integration periods;
- and
- wherein the drive and sense circuitry determines interior motion within a volume of space proximate to the transmitting conductor and the receiving conductor based upon the measured interactions during a plurality of integration periods.

A method comprising the steps of:
- generating a plurality of frequency-orthogonal signals on each of a plurality of transmitting conductors, respectively;
- receiving signals on a plurality of receiving conductors, the plurality of receiving conductors being oriented such that each of the plurality of transmitting conductors forms an interacting pair of conductors with at least one of the plurality of receiving conductors;
- processing the received signals received during an integration period to determine a measurement corresponding to each of the plurality of frequency-orthogonal signals for each of the received signals;
- and
- determining an interior motion based upon the measurements during a plurality of integration periods.
