Patent number: 8594114Abstract: A bus driver circuit divides an internal data bus for an integrated circuit memory into at least two groups, designated by speed. A faster group of data lines and a slower group of data lines are placed in an interleaved fashion in order to provide a two group shielding solution. At the earliest opportunity following the reception of a read command, the data from memory banks in the memory is sorted into these two groups. For a DDR3 memory, the sorting method is based on the A2 column address, known as C2. All of the data is brought out of the banks in parallel and sorted as it enters the main amplifiers. These main amplifiers are also divided into two groups, faster and slower. Each amplifier then connects to a data line (G-line) of the same group. The clock assigned to the fast group fires right away, thereby connecting the data associated with the fast amplifiers to the fast data group. This data group then proceeds to the output buffers through the entire data path as fast as possible.Type: GrantFiled: May 29, 2008Date of Patent: November 26, 2013Assignee: ProMOS Technologies PTE.

Patent number: 8537856Abstract: Briefly, in accordance with one embodiment of the invention, a wireless terminal may include an application subsystem and a communication subsystem. The communication subsystem in one embodiment may enable a virtual direct interface to a remote network to be presented to the application subsystem via a wireless communication system air link interface. The communication subsystem may allow applications of the application subsystem to be independent of any particular radio technology or network implementation of a wireless communication system air link interface. Once a session is established between the communication subsystem and the wireless communication system air link interface, the application subsystem may gain access to the remote network through the communication subsystem via a transport interface.Type: GrantFiled: November 11, 2009Date of Patent: September 17, 2013Assignee: Intel CorporationInventor: Matthew A.

Patent number: 8537847Abstract: A wedge-shaped digital clock wirelessly receives weather, traffic, and other information over the Internet for display along with the time of day. The clock is wedge-shaped so that it can rest in two orientations, one with the display tilted back slightly from vertical and one with the display substantially horizontal. An accelerometer can signal the orientation to an internal processor, which can flip the text on the display as appropriate for the user flipping or turning the housing upside down, for example.Type: GrantFiled: June 22, 2010Date of Patent: September 17, 2013Assignee: Sony CorporationInventors: Hiroya Fujii, Isamu Arie, Ronald Clark, Justin Randolf Jakobson, Yuji Oikawa, Joe Wada, Rui Yamagami, Takuo Ikeda, Chia-Yao Lin, Junghee Yeo

Patent number: 8532121Abstract: End-point devices, access points and other types of network nodes each employ multi-path management software to manage communication via multiple possible paths to the Internet backbone from communication applications that run on an end-point device. Although the multi-path management software on an end-point device may operate independently, it may also cooperate with the local communication applications and the multi-path management software located on the access points or other network nodes to select one or more pathways for the local communication applications. Alternatively, the multi-path management software of an end-point device may pass all or a portion of such management responsibility to a local communication application and/or to multi-path management software of another network node. In addition to managing the selection of one or more pathways, the multi-path management software seamlessly switches pathways as may become necessary to meet changing network conditions or bandwidth demands.Type: GrantFiled: September 29, 2009Date of Patent: September 10, 2013Assignee: Broadcom CorporationInventor: James D.

Patent number: 8531985Abstract: A network device includes port interfaces and a traffic buffer configured with queue sets for buffering packets transmitted or received on the port interfaces. The network device also includes a management module that stores one or more queue set profiles. The queue set profiles specify configuration parameters for buffering and managing traffic in the queue sets. To configure a queue set, one of the queue set profiles is associated with the corresponding port interface and the configuration parameters are applied to the queue set. This queue set is then configured in accordance with the queue set profile. Management of port interfaces is thus performed by applying a queue set profile to similar groups of queue sets.Type: GrantFiled: July 28, 2011Date of Patent: September 10, 2013Assignee: Alcatel LucentInventors: Prashant R.

Patent number: 8526424Abstract: An improved telephony adapter compresses voice data, creates IP packets, and prioritizes the voice IP packets over the data IP packets. Preferably, the compression and packetization interval is such that the bandwidth occupied by the voice IP packets is approximately half of the minimum average available bandwidth in the upstream direction, thereby maintaining acceptable latency and voice quality of the speech. Further enhancement is achieved by causing the ISP to also give priority to voice packets that are destined to the telephony adapter, over the data packets that are destined to the telephony adapter.Type: GrantFiled: April 14, 2009Date of Patent: September 3, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: Ali M.
