  • Publication number: 20210007248
    Abstract: An electronic module includes an operational subunit, having upper, lower and lateral surfaces, and including one or more electronic components, which are adjacent to the lower surface of the operational subunit and generate heat when the module is in operation. A heat sink is disposed in proximity to the lower surface of the operational subunit. A heat spreader, including a continuous sheet of a heat-conducting material, is folded to wrap around the operational subunit so that a lower side of the sheet is interposed between the lower surface of the operational subunit and the heat sink and a lateral side of the sheet extends around at least one of the lateral surfaces of the operational subunit.

  • Patent number: 10877557
    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.

  • Patent number: 10754440
    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.

  • Patent number: 10725573
    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.

  • Publication number: 20150070037
    Abstract: Systems and methods to fixture and utilizing a probe which tests a capacitive array are described herein. A support bracket with freedom about a plurality of axes may aid in locating a probe and allowing the probe to contact multiple surfaces consistently. By utilizing the support bracket, the angle between a test probe and a contact surface may be minimized such that the surface of the test probe and the contact surface may rest flat against one another. The system may also limit the force translated through support bracket. This system and method may allow for a high degree of accuracy and a high degree of precision during contact of the test probe and the test surface.
