  • Publication number: 20120050464
    Abstract: A three-dimensional (3D) video rendering device monitors 3D effects associated with an object in a received 3D video image-by-image. The object may be re-located to a preferred location to adjust the associated 3D effects. Two-dimensional (2D) image data and corresponding depth information for the object at the current location are interpolated to the preferred location. A location difference and lighting condition changes corresponding to the re-location of the object are calculated to determine a view angle and lighting conditions for the object at the preferred location. 2D image data and depth information for the object at the preferred location are estimated based on the determined view angle and the determined lighting conditions for the object at the preferred location. The estimated 2D image data and the estimated corresponding depth information may be applied to the object at the preferred location to enhance the associated 3D effects for 3D video rendering.

  • Patent number: 8019342
    Abstract: A process of maintaining access information between wireless hotspots is disclosed. A logon request from a wireless portable device is received by a first access point of a first wireless hotspot and use of the first access point by the wireless portable device is authenticated to establish an access session. Then, information related to the access session is passed to a shared register accessible by a plurality of wireless hotspots and the access session is monitored to determine whether a disconnect by the wireless portable device occurs. Additionally, when the wireless portable device moves from a coverage area of the first wireless hotspot to one coverage area of one of the plurality of wireless hotspots, the information related to the access session may be used to facilitate access to the one of the plurality of wireless hotspots by the wireless portable device.

  • Publication number: 20110161831
    Abstract: A system and method for sharing a view between systems in a dynamic wireless communication network. Various aspects of the present invention may comprise a first system communicating information of a view to a display resource of the first system. The first system may establish a two-way wireless communication link between the first system and a second system in the dynamic wireless communication network. The second system may, for example, communicate a request to the first system for the first system to share a view with the second system. The first system may, for example, receive such a request and respond to such a request by communicating information of a view to the second system. The second system may then communicate information of the view to a display resource of the second system. Various aspects may comprise the first and second systems communicating view modification information between the systems.

  • Patent number: 7941180
    Abstract: A hand held radio host includes circuitry for selectively providing power to radiating transceiver elements and non-radiating application elements according to a plurality of power modes of operation to achieve desired effects and in a way that saves power and extends battery life. In one embodiment of the invention, the hand held host operates in one of three modes. In a full power mode, any selected application element as well as all transceiver elements are powered on at the same time. Thus, for example, a cell phone module, a wireless personal access network module, a wireless local area network module and one of a pager/short message service message module may all be powered on at the same time to receive corresponding messages, calls, data sessions, etc. At the same time that all of the transceiver elements are powered on, any selected application element receives power. Thus, application elements such as address books, calendar functions, games, word processors, etc may receive power when selected.

  • Patent number: 7684521
    Abstract: Typical communication systems operate with a single channel decoder, and hence would have to settle for the performance from the single channel decoder regardless of the conditions of the communications channel. The present invention uses a hybrid channel decoder comprising multiple channel decoders, each configured to optimize the quality of the re-constructed signal for different channel conditions. Therefore, the desired decoder can be selected as conditions of the communications channel, or the data signal, change over time, so as to optimize the re-constructed data signal. In embodiments, the data signal is a speech signal.

  • Publication number: 20090327845
    Abstract: A system, method and computer program product is provided for mitigating the effects of burst noise on packets transmitted in a communications system. A transmitting device applies an outer code, which may include, for example, a block code, an exclusive OR (XOR) code, or a repetition code, to one or more packets prior to adaptation of the packets for transmission over the physical (PHY) layer of the communications system, wherein the PHY layer adaptation may include FEC encoding of individual packets. The outer coded packets are then separately transmitted over a channel of the communications system. A receiving device receives the outer coded packets, performs PHY level demodulation and optional FEC decoding of the packets, and then applies outer code decoding to the outer coded packets in order to restore packets that were erased during transmission due to burst noise or other impairments on the channel.
