    摘要: An input device and system are described that acquires (measures) raw track pad sensor data and transmits this data to a host computer where it is analyzed by an application executing on one or more host computer central processing units. The resulting input processing architecture provides a track pad input device that is both lower in cost to manufacture and more flexible than prior art track pad input devices. Lower costs may be realized by eliminating the prior art's dedicated track pad hardware for processing sensor data (e.g., a processor and associated firmware memory). Increased flexibility may be realized by providing feature set functionality via software that executes on the host computer. In this architecture, track pad functionality may be modified, updated and enhanced through software upgrade procedures.

    摘要: A force imaging touch pad includes first and second sets of conductive traces separated by a spring membrane. When a force is applied, the spring membrane deforms moving the two sets of traces closer together. The resulting change in mutual capacitance is used to generate an image indicative of the amount or intensity of the applied force. A combined location and force imaging touch pad includes two sets of drive traces, one set of sense traces and a spring membrane. In operation, one of the drive traces is used in combination with the set of sense traces to generate an image of where one or more objects touch the touch pad. The second set of drive traces is used in combination with the sense traces and spring membrane to generate an image of the applied force's strength or intensity.

    摘要: A printed circuit board (PCB) assembly provides a two layer capacitive trackpad sensor in which an EMI ground grid is interposed among the sensor's capacitive elements on each of its layers. The EMI grid on each of the two layers is electrically coupled via, typically, vias. The described arrangement of sensor elements (capacitor plates) and EMI ground grid traces may be incorporated into a PCB having additional layers (e.g., a four, six or eight layer PCB). If used in this manner, additional vias are provided on the PCB which permit electrical coupling between these “additional layers” and which are electrically isolated from, and shielded by, the EMI ground grid.

    摘要: Single and dual wire gyroscopes determine the orientation and attitude of a device using optical sensing of radiation interrupted by current-carrying, vibrating tensioned wires within a magnetic fields. The tensioned wires vibrate between end nodes within the respective magnetic fields to provide both sustaining oscillatory drives and the sensing of velocity in the directions perpendicular to the respective magnetic fields. Lateral displacements of tensioned wires in directions parallel to the associated magnetic fields are sensed using radiant illumination of the wires and radiation sensing below the wires to provide displacement signals. Precession of wires in vibratory trajectories out of planes perpendicular to respective magnetic fields are controlled by selectively twisting and bending the tensioned wires between mounting ends.

    摘要: An electronic device may have a display with a brightness that is adjusted based on ambient light data from one or more ambient light sensors. An ambient light sensor may be formed from a semiconductor substrate such as a silicon substrate. Sensor structures may be formed in the silicon substrate. Conductive vias or other conductive paths may be used to interconnect sensor structures on a frontside surface of the ambient light sensor to contacts on a backside surface of the ambient light sensor. The ambient light sensor may be mounted on a substrate layer in the electronic device. The substrate layer may be a planar layer of glass or plastic such as a transparent display layer. The contacts of the ambient light sensor may be mounted to corresponding contacts on the surface of the substrate layer. The substrate layer may be a thin-film transistor layer in a liquid crystal display.
