摘要： A physical disturbance sensor includes a plurality of piezoresistive elements configured in a resistive bridge configuration. A signal transmitter is electrically connected to the physical disturbance sensor and configured to send an encoded signal to the piezoresistive elements of the resistive bridge configuration. A signal receiver is electrically connected to the piezoresistive elements and configured to receive a signal from the physical disturbance sensor. The received signal from the physical disturbance sensor is correlated with the sent encoded signal in determining a measure of physical disturbance.

摘要： A propagating signal transmitted through a propagating medium is received where a detected disturbance to a signal property of the propagating signal is analyzed to detect whether a touch input has been provided. It is determined whether the detected disturbance matches a signature and in the event it is determined that the detected disturbance matches the signature, it is determined that the detected disturbance does not correspond to the touch input.

摘要： At a receiver associated with a transmitter-receiver pair, a propagating signal transmitted by a transmitter associated with the pair is received. A detected disturbance to a signal property of the propagating signal is analyzed with respect to reference data associated with the pair to detect whether a touch input has been provided. If the detected disturbance meets a criteria then the reference data associated with the pair is updated using the received propagating signal.

摘要： Detecting a location of a touch input on a surface of a propagating medium is disclosed. A transmitter coupled to the propagating medium emits a signal. The signal is received using a receiver coupled to the propagating medium. The receiver is configured to receive the signal from the transmitter to at least in part detect the location of the touch input as indicated by an effect of the touch input on the signal. Spectral control of the signal is performed.

摘要： A signal to be used to propagate a freely propagating signal through a propagating medium with a touch input surface is sent. The freely propagating signal has been allowed to freely propagate through the propagating medium in a plurality directions to a plurality of receivers on multiple axes of the propagating medium. A received signal detected due to a touch input object contacting the touch input surface is received. The received signal includes the freely propagating signal that has been disturbed by the touch input object. At least a portion of the received signal is compared with one or more reference signals of one or more touch input object types. Based at least in part on the comparison a location of the touch input object contacting the surface is determined.

摘要： Detecting a location of a touch input is disclosed. Each of a plurality of transmitters coupled to a propagating medium emits a signal that is distinguishable from other signals emitted from other transmitters. The signals from the transmitters are received from at least one receiver coupled to the propagating medium to detect the location of the touch input on a surface of the propagating medium as indicated by an effect of the touch input on each of the distinguishable signals.
