Abstract: Acoustic touch sensing systems can include a mechanically integrated structure including multiple acoustic transducers. For example, an annular structure including one or more piezoelectric segments can be fabricated and then coupled to a front crystal/cover glass. A single structure can simplify the structural integration of the device, can provide a mechanically reliable and stable structure for improved structural integrity of the system, and can provide for improved water sealing for a waterproof or water resistant device. The piezoelectric material in the annular structure can be shear poled such that a poling direction of the piezoelectric material can follow the curvature of the annular piezoelectric structure.

Abstract: This disclosure relates to a VR glove capable of measuring the movement of individual finger and thumb bones. The VR glove can include a plurality of inertial measurement units (IMUs) to track the movement of one or more finger and/or hand sections. The IMUs can include one or more motion sensors, such as a gyroscope and an accelerometer, for measuring the orientation, position, and velocity of objects (e.g., finger bones) that the IMU can be attached. An IMU can be located proximate to a finger (or thumb) bone and can measure the inertial motion of the corresponding bone. In some examples, the VR glove may include magnetometers to determine the direction of the geo-magnetic field. The VR glove can also include one or more other electronic components, such as a plurality of electrodes for sensing the heading, enabling capacitive touch, and/or contact sensing between finger tips.

Abstract: Touch sensitive mechanical keyboards and processes for detecting touch events and key depressions on the touch sensitive mechanical keyboard are provided. The touch sensitive mechanical keyboard can include a set of individually depressible mechanical keys having a touch sensitive surface. A touch sensor layer can be disposed on top of a key mechanism and flexible interconnections provided between key segments of the touch sensor layer can allow for depression of the key mechanism of individual keys. In some examples, the flexible interconnections can be formed by patterning a spring-like structure into the touch sensor layer. In some examples, the touch sensor layer can be transparent or include openings to allow a backlight to shine through. In some examples, addressable LED backlighting with buckling interconnects can also be provided to illuminate keycaps of the mechanical keyboard.

Abstract: A haptic actuator may include a housing, at least one coil carried by the housing, and a field member having opposing first and second sides. The haptic actuator may also include a respective at least one flexure bearing mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the at least one coil. Each flexure bearing may include at least one flexible member having a wishbone shape with two diverging arms joined together at proximal ends and having spaced distal ends operatively coupled between adjacent portions of the field member and the housing.
