  • Patent number: 10067625
    Abstract: A force applied to a force-sensing touch screen device may be determined as follows. A deformation sensing layer of the device may measure an actual deformation of a touch screen of the device. A force sensor of the device may measure a sensed force applied by the touch screen to the force sensor of the device. A processor circuit of the device may determine an expected deformation expected to be imparted to the touch screen by the sensed force. The processor circuit may determine a virtual deformation based on the expected deformation due to the sensed force and the measured actual deformation. The virtual deformation may indicate the force applied to the force-sensing touch screen.

  • Patent number: 8109878
    Abstract: A method for detecting a target or targets in a medium. The method incorporates generating beams of ultrasonic wave energy each having a modulation envelope and causing each beam of wave energy to impact a target region having a multiplicity of targets and demodulating each signal generated by vibration of each target caused by the interaction of a respective ultrasound wave energy beam having a modulation envelope with each of the targets and receiving each demodulated signal from each target by a multiplicity of sensors. Thereafter, each time-of-flight of each demodulated signal from each of the targets to each of the multiplicity of sensors is computed to determine the location of a respective target.
