Abstract: A multi-virtual button finger-touch input system includes a cover layer, force-measuring and touch-sensing integrated circuits (FMTSICs), each coupled to the inner surface of the cover layer corresponding to one of the virtual buttons, an elongate flexible circuit, and a host controller. The FMTSICs are mounted to the elongate flexible circuit. The host controller is in communication with each of the FMTSICs via digital bus wiring. The host controller is configured to: (1) obtain force-localization features and ultrasound-localization features of the FMTSICs and (2) determine whether an event is a finger-touch event or a false-trigger event and if the event is determined to be finger-touch event, identify one of the virtual buttons as a touched virtual button, using at least in part a model that has the force-localization features and the ultrasound-localization features as inputs. The force-localization features and ultrasound-localization features are derived from the PMFE digital data and the PMUT digital data respectively.

Abstract: A touch panel has a substrate having first and second surfaces, and defines a touch surface. A first portion of a touch system includes a first plurality of echelons on the first surface in a first array along a first centerline. Each echelon is formed at an angle to the first centerline, and a first shear transducer assembly on the edge of the substrate that generates a shear wave in a source wave mode in a first direction along the first centerline. A second portion of the touch system includes a second plurality of echelons on the first surface in a second array along a second centerline, each echelon at a second angle to the second centerline. The second centerline is orthogonal to the first. A second shear transducer assembly is mounted on the edge and generates a shear wave in a source wave mode in a second direction along the second centerline. The first sensing mode is different from the second sensing mode.

Abstract: An apparatus may include an ultrasonic sensor system, a low-frequency vibration source and a control system. The ultrasonic sensor system may include an ultrasonic receiver and an ultrasonic transmitter configured for transmitting ultrasonic waves in a first frequency range (e.g., 1 MHz to 30 MHz). The low-frequency vibration source may be configured for generating low-frequency vibrations in a second frequency range (e.g., the range of 5 Hz to 2000 Hz). The control system may be configured for synchronizing the generation of the first low-frequency vibrations and the transmission of the first ultrasonic waves.
