  • Patent number: 8022867
    Abstract: A global navigation satellite system-tracking (“GNSS-tracking”) device and method for determining one or more positions of the GNSS-tracking device utilizing a user-plane service is disclosed. The GNSS-tracking device may comprise: charging and tracking modules adapted to be disengagably coupled together, wherein the tracking module comprises (i) tracking circuitry for determining at least one position of the tracking module using the user-plane service in a satellite positioning system, and (ii) a chargeable source for supplying power to the tracking circuitry when disengaged from the charging module, and wherein the charging module is operable to charge the chargeable source when the charging module is coupled to the tracking module.

  • Patent number: 6972953
    Abstract: An apparatus for removing heat from heat generating elements is disclosed. The apparatus is a thermal management system having a thermal distribution assembly in either one of or both of conductive and radiative communication with heat generating elements. The thermal distribution assembly has thermal zones, each of which is associated with at least one heat generating element. The thermal distribution assembly includes a heat spreading frame and a heat conducting frame. Heat passes from the heat generating elements to the heat conducting frame and then to the heat spreading frame, from which the heat is removed via convection.

  • Publication number: 20030008671
    Abstract: A wireless device having position location capabilities that are further enhanced by circuitry that enables the wireless device to compute its local orientation. The wireless device includes a wireless transceiver subsystem, a position location receiver subsystem, a central processing unit (CPU), a memory, and a user interface. The CPU is coupled to local orientation data sensors that provide information regarding the local orientation of the device. The device orientation and position of the wireless device is used to identify certain information that is requested by the device. The information is then displayed to the user at the remote device.

  • Patent number: 6275595
    Abstract: A high quality stereophonic sound enclosure system high resolution intended for computer visual display monitors employing cathode ray tubes (CRTs) having a vertical aperture grill, and methods for construction of same. The aperture grill has a natural frequency centered within the musical scale. The stereo speaker system comprises a ported speaker enclosure within which are mounted two conventional cone speaker assemblies. A stereo audio amplifier and control unit for controlling the audio signals delivered to the speakers is mounted within the speaker enclosure. The speaker enclosure is internally mounted within the monitor with a minimum number of attachment members incorporating vibration isolation material to remove vibration components near the natural frequency of the aperture grill. The speaker enclosure is internally reinforced to reduce structural deformations which contribute to airborne transmitted vibration within the monitor housing when the speaker system is operating.

  • Patent number: 5946403
    Abstract: A directional microphone intended for use in a computer visual display monitor, and methods for construction of same. The integral directional microphone assembly comprises a cardioid electret microphone capsule retained therein by acoustically transparent foam. The microphone housing is mounted internally within a display monitor housing facing the user and adjacent to the top surface of the monitor housing. The microphone housing comprises a frontal opening and a plurality of nonfrontally facing openings which together maximally preserve sound pressure gradient applied to the microphone capsule, resulting in a hypercardioid spatial response.

  • Patent number: 5216326
    Abstract: An improved degauss coil for use with cathode ray display tubes is disclosed. The degauss coil is formed from conductive traces placed directly on to a plastic part attached to or adjacent the front bezel surrounding the cathode ray tube. Alternatively, the conductive traces may be placed directly on to the bezel itself. The invention allows for a very narrow bezel border surrounding the cathode ray tube.
