Abstract:
Disclosed are keyboards and keyboard switches sensitive to touch, including, hover and pressure. The keyboard switches have transmit and receive antennae that are spaced apart such that no portion of the transmit antenna touches any portion of the receive antenna. The keyboard switches are arranged in logical rows and logical columns such that each of the keyboard switches is associated with one row and one column. Signal emitters are conductively coupled to the transmit antennae for each of the keyboard switches associated with each of the rows, and each of the signal emitters are adapted to cause each of the transmit antennae to transmit one or more source signals. Receivers are coupled to the receive antennae for each of the keyboard switches associated with each of the columns, and each of the receivers are adapted to capture a frame of signals present on the coupled receive antennae. A signal processor adapted to determine a measurement from each frame, corresponding to an amount of the source signals present on the receive antennae during a time the corresponding frame was received. The signal processor further adapted to determine a keyboard switch touch state from a range of touch states based at least in part on the corresponding measurement.

Claim (Index 11):
A keyboard switch for detecting touch, the keyboard switch comprising:\n key base; key cover, the key cover being movable with respect to the key base, wherein the key cover comprises a conductive substrate to magnify capacitive effect; transmit antenna and a receive antenna, the transmit and receive antennas being configured such that no portion of the transmit antenna touches any portion of the receive antenna, wherein at least one of the transmit and receive antennas is moveable with respect to the other;\n wherein the transmit antenna is adapted to be used to transmit one or more source signals; \n wherein the receive antenna is adapted to be used to capture a frame of signals; and \n signal processor operatively connected to the receive antenna, the signal processor adapted to:\n (i) receive a plurality of frames of signals incident on the receive antenna, each of the frames corresponding to a period of time; \n (ii) determine at least one measurement corresponding to each frame of the plurality of frames, each such measurement corresponding to the one or more source signals; and \n (iii) determine a keyboard switch touch state from a range of at least three touch states, the keyboard switch touch state based at least in part on the corresponding measurement, wherein at least one of the range of touch states corresponds to a fully depressed key.
