Patents by Inventor Tzeng-Fu Kao

Tzeng-Fu Kao has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10884558
    Abstract: An input device includes a plurality of sensor electrodes, an antenna, and a shield trace disposed between at least some of the sensor electrodes and the antenna. The antenna may be coupled to a transceiver and may transmit and receive radio-frequency (RF) communication signals. The shield trace may reduce, at least in part, coupling of the RF communication signals from the antenna to the sensor electrodes. The plurality of sensor electrodes may determine a presence, and/or a motion associated with an input object.
    Type: Grant
    Filed: January 28, 2019
    Date of Patent: January 5, 2021
    Assignee: Synaptics Incorporated
    Inventors: Tzeng-Fu Kao, Christopher Chongbin Rehn
  • Patent number: 10880990
    Abstract: A force pad sensor includes a face sheet including a force sensing resister, and a printed circuit board assembly. The printed circuit board assembly includes a proximity sensor layer including a proximity receiver electrode and a proximity transmitter electrode, and a force sensor layer including a force receiver electrode and a force transmitter electrode. The force receiver electrode and the FSR intersect a same vertical plane, the vertical plane being perpendicular to the face sheet.

  • Patent number: 9898095
    Abstract: In an example, an isometric input device configured to control a user interface indicator of an electronic device includes a plurality of sensor electrodes disposed on a sensor substrate. The input device further includes a control member mechanically coupled to the sensor substrate over at least a portion of the plurality of sensor electrodes. The input device further includes a conductive support substrate and a compliant member disposed between the sensor substrate and the conductive support substrate. The input device further includes a securing component extending through the conductive support substrate and the compliant member and engaging with the control member, the securing component defining a gap between the sensor substrate and the conductive support substrate.
