20090085801 | Method and Apparatus for Faster Global Positioning System (GPS) Location Using Pre-Downloaded Assistance Data - A method and apparatus for faster global positioning system (GPS) location using pre-downloaded assistance data are described. In one embodiment, the method includes the periodic acquisition of assistance data when a GPS receiver is disabled. In one embodiment, the GPS receiver may be disabled due to a spatial location of a mobile platform device (MPD) that includes the GPS receiver. During the periodic acquisition of the assistance data, the GPS receiver may be monitored. In one embodiment, in response to activation of the GPS receiver, the assistance data is provided to the GPS receiver to reduce a time to first fix (TTFF) following lock onto a predetermined number of visible satellites to establish a current spatial location of the MPD. Other embodiments are described and claimed. | 04-02-2009 |
20090129265 | METHODS AND MEDIA ACCESS CONTROLLER FOR BROADBAND WIRELESS COMMUNICATIONS WITH VARIABLE DATA UNIT SIZE AND DELAYED DATA UNIT CONSTRUCTION - A media access controller (MAC) of a broadband wireless communication device may vary the size of data unit payloads based on a physical layer burst size. In automatic retransmission request (ARQ) enabled service flows, the MAC may delay construction of data units from the data unit payloads until after entering an ARQ retransmission request window. In some embodiments, the MAC comprises per-flow schedulers to schedule service data units (SDUs) for each of a plurality of service flows, and per-service flow retransmission request handlers to reconstruct and retransmit data units. | 05-21-2009 |
20090172431 | METHOD AND APPARATUS FOR REDUCING POWER CONSUMPTION FOR ISOCHRONOUS DATA TRANSFERS - A method and article for reducing power consumption for isochronous data transfers are described. The method may include receiving packets of data having multimedia information with empty spaces. The packets of data may be stored in a first buffer having a first buffer size allocated for a universal serial bus processing stack. The empty spaces may be removed from the packets of data and the packets of data having the empty spaces removed may be copied to a second buffer having a second buffer size allocated for a media information processing stack. Other embodiments are described and claimed. | 07-02-2009 |
20090243929 | METHOD AND APPARATUS FOR FASTER GLOBAL POSITIONING SYSTEM (GPS) LOCATION USING A PRE-COMPUTED SPATIAL LOCATION FOR TRACKING GPS SATELLITES - A method and apparatus for faster global positioning system (GPS) location using pre-computed spatial location data are described. In one embodiment, a method includes acquiring a pre-computed spatial location of a mobile platform device (MPD) that is computed when a GPS receiver is disabled due to the spatial location of the MPD. In one embodiment, the pre-computed spatial location is determined by a non-GPS based spatial location technology when a receiver is disabled due to the spatial location of the MPD. During the periodic computation of spatial location data, the GPS receiver may be monitored. In one embodiment, in response to activation of the GPS receiver, the pre-computed spatial location data is provided to the GPS receiver for identification and lock onto a predetermined number of visible satellites to reduce a time to first fix (TTFF) a current spatial location of the MPD. Other embodiments are described and claimed. | 10-01-2009 |
20100070652 | Synchronization of multiple incoming network communication streams - A device, method, and computer readable medium are disclosed. In one embodiment the device includes a first network packet storage queue that is capable of storing incoming network packets from a network. The device also includes a second network packet storage queue that is capable of storing incoming network packets from a network. The device also includes flush logic to synchronize a flush of the network packets stored in the first and second network packet storage queues. The flush is triggered by a flush event affecting at least one of the storage queues. | 03-18-2010 |
20100082955 | VERIFICATION OF CHIPSET FIRMWARE UPDATES - In general, in one aspect, the disclosure describes an apparatus that includes updatable non-volatile memory to store firmware and non-updateable non-volatile memory to store an interrupt sequence. The apparatus includes a chip interface to receive an interrupt instruction from management firmware. Receipt of the interrupt instruction controls access to and initiation of the interrupt sequence. After initiation of the interrupt sequence the apparatus may receive a firmware update and/or validate the firmware is from a valid source. The validation of the firmware may include utilizing the management firmware to verify the cryptographic signature for the firmware. | 04-01-2010 |
