  • Patent number: 9354751
    Abstract: An input device is disclosed that can improve input detection associated with sensor elements that exhibit a weaker response at the lower end of their dynamic range than their counterparts. This can be advantageous when implementing input reporting rules that rely on a sufficient response at the lower end of a sensor element's dynamic range. The input device can compensate for a weak sensor element at the low end of its dynamic range by increasing its sensitivity in certain situations, such as when an adjacent sensor provides a strong input signal, or after the weak sensor element provides a signal level exceeding a noise threshold for example. The sensitivity of the weak sensor element can be increased in a variety of ways, such as by reducing a noise threshold associated with the sensor element or boosting a signal level associated with the sensor element for example.

  • Patent number: 7728823
    Abstract: 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.

  • Publication number: 20070229464
    Abstract: 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.

  • Publication number: 20070194842
    Abstract: A synchronous signal processing circuit for a dual-axis vibratory rotation-rate sensor uses a hybrid analog/digital design to provide correction for parasitic quadrature errors by the addition of synthesized correction signals in the analog domain prior to digitization. Error correction, signal demodulation and data conversions are synchronized with a signal phase-locked to the measured motion of the vibratory mass. Similarly, cross-axis error correction signals are synthesized directly from the cross axis signals. Use of these precise phase references provides for various benefits in signal noise and error matching (tracking) over wide operation conditions.

  • Publication number: 20070186652
    Abstract: A vibratory rotational rate gyroscope has a suspended assembly isolated from external vibrations by an arrangement of helical springs. This isolated assembly includes both the active components of the rotational rate gyroscope and a digital processing circuit. The digital processing circuit includes digital storage for both externally determined and internally determined unit-specific calibration values. These values provide seed values for startup processes, which improves loop startup time, and values for unit-specific electronic calibration. The digital processing circuit further converts all data to digital form. A digital communications protocol is used to transmit the calibration information and the outgoing data to and from the isolated assembly on only two conductors. Two additional conductors used for power. Four of the helical springs used in the suspension arrangement are used for these conductors such that no additional wiring is required.

  • Publication number: 20070177316
    Abstract: A dual-axis rotational rate sensor having two vibratory masses coupled to a restoring element and driven in a resonant counter-phase motion, wherein the two masses vibrate with equal but opposite amplitudes along a single axis. The vibratory structure also accommodates motion of the masses in a plane orthogonal to the vibratory axis. Measurement of the motion of the masses in two axes in this plane provides signals directly responsive to rotation of the sensor about two orthogonal axes. Measurement and drive is facilitated by the use of magnetic masses and electromagnetic drive and sense transducers.

  • Publication number: 20060238517
    Abstract: An electronic device has a display and has a touch sensitive bezel surrounding the display. Areas on the bezel are designated for controls used to operate the electronic device. Visual guides corresponding to the controls are displayed on the display adjacent the areas of the bezel designated for the controls. Touch data is generated by the bezel when a user touches an area of the bezel. The device determines which of the controls has been selected based on which designated area is associated with the touch data from the bezel. The device then initiates the determined control. The device can have a sensor for determining the orientation of the device. Based on the orientation, the device can alter the areas designated on the bezel for the controls and can alter the location of the visual guides for the display so that they match the altered areas on the bezel.

  • Publication number: 20060066581
    Abstract: 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.

  • Publication number: 20050254255
    Abstract: A light guide panel is disclosed. The panel comprises a plate for dispersing light and at least one light-emitting diode (LED) coupled to the plate for providing the dispersed light. When the panel is coupled to a keyboard, the at least one LED is under a portion of the keyboard such that when the at least one LED is illuminated, the light from the LED does not distract a user. Accordingly, by strategically placing LEDs within the panel and providing the LEDs under appropriate portions of the keyboard, the device utilizing the keyboard can be smaller than when a conventional light guide panel is utilized. In addition, a further improvement in illumination is provided when a mechanism is provided which reflects light escaping from the edges of the panel back into the panel.
