  • Patent number: 9317639
    Abstract: A method for reducing dynamic power consumption of an integrated circuit design having flip-flops with an EDA tool that initiates clock gating by gating a clock signal received by the flip-flops. A first set of positive-edge triggered flip-flops and a second set of negative-edge triggered flip-flops, and a first set of OR-type clock gating cells and a second set of AND-type clock gating cells are selected from a technology library. The OR-type clock gating cells are connected to clock input terminals of the first set of positive-edge triggered flip-flops and the AND-type clock gating cells to clock terminals of the second set of negative-edge triggered flip-flops.

  • Publication number: 20150236986
    Abstract: A communication system transfers user data messages to users. The system stores the user data messages in association with message stream identifiers and message delivery metrics. The system processes the message delivery metrics to enter the user data messages into a plurality of delivery queues associated with multiple message transmission systems. The system receives a data request indicating a message stream identifier and a message transmission system, and in response, identifies a message set and associated delivery metrics. The system receives a data instruction indicating new delivery metrics, and in response, re-enters the message set into the delivery queue. The communication system transfers the user data messages based on their associated delivery queues over data networks for receipt by the users.

  • Publication number: 20150089004
    Abstract: A method (and corresponding equipment) by which a multimedia message is sent from a sending terminal (21) via a messaging server (22)—such as a MMS Proxy-Relay in MMS or a SIP proxy server in SIP IM—to a receiving terminal (25) having limited multimedia capabilities, with the sending terminal (21) adapted to include a user agent (21a) for inserting, into the message, media characteristics of the message sufficient in detail to enable the messaging server (22) to determine whether the message should be transcoded based on actual or assumed multimedia capabilities of the receiving terminal (25), and with the messaging server (22) configured to read the media characteristics and decide whether the message should be transcoded based only on the inserted media characteristics and on actual or assumed multimedia capabilities of the receiving terminal (25). The media characteristics are advantageously inserted into the header of the message.

  • Publication number: 20140351354
    Abstract: An approach is provided for facilitating the sharing of information related to an item of interest as a web link via data messaging. The messaging client determines a request to share information related to an item of interest. The messaging client then causes an encoding of the information, geo-coded information, sharing destinations, and user credentials for the sharing destinations into a communication. The messaging client further causes a transmission of the communication to a web server. Next, the message platform determines a request to create a web link for sharing information related to an item of interest, wherein the request includes a communication encoding the information, sharing destinations, and user credentials. The message platform then processes and/or facilitates a processing of the request to cause a creation of a web link based on the communication. The message platform further determines to make the web link available to the sharing destinations.

  • Patent number: 8831652
    Abstract: An approach is provided for crowd sourcing and grouping points-of-interest based on cell broadcast message information. Reception of a message from a mobile terminal is caused, at least in part. The message specifies point-of-interest information and an associated area name corresponding to one of a plurality of cells of a communication network. The message is parsed to determine the point-of-interest information and the associated area name. A connectivity graph specifying relationships among the cells is selectively updated with the point-of-interest information.

  • Patent number: 8350592
    Abstract: A single-supply digital voltage level shifter has a first inverter having a first input for receiving an input signal with a first voltage swing, and a first output for outputting a first output signal. A second inverter has a second input for receiving the first output signal, and a second output for outputting a second output signal with a second voltage swing, where the second output signal is a level-shifted version of the input signal. A comparison stage includes a first comparison stage input for receiving the input signal, a second comparison stage input for receiving the second output signal, and a comparison stage output for outputting a comparison stage output control signal. A control stage is connected in a circuit branch of the first inverter and has a control stage switch that assumes a non-conducting state dependent on a logical state of the comparison stage output control signal.

  • Publication number: 20120278945
    Abstract: The present invention relates to the development of a novel clone of Vetiver [Vetveria zizaniodes (L) Nash. syn. Chrysopogon zizaniodes (L.) Roberty; family Poaceae], named ‘CIMAP-KHUS 40’ characterised by somatic chromosome number 4x=40, larger stomata, fast growing deep penetrating roots, and seed infertility disabling its spread as a weed. This clone has unique ISSR and RAPD profiles that serve as DNA-fingerprints, and is developed from a unique diploid plant (2n=20). The invention document details all the pertinent data relating to this clone, its biological features and usefulness, and the method of its development.

  • Patent number: 8242051
    Abstract: The present invention provides a novel adsorbent carbon supported activated alumina (CSAA) which posses both the advantageous characteristics of carbon and alumina viz., the high specific surface area associated with activated carbon and high sorption capacity of alumina towards F? Carbon supported activated alumina has an added advantage of its usage in the neutral pH unlike alumina and alumina impregnated carbon which are found to be efficient only in acidic pH. It is more efficient compared to carbon in terms of its sorption capacity towards F? and is therefore useful for the efficient removal of fluoride ions from water.

  • Publication number: 20110208810
    Abstract: Methods and systems for optimizing server polling by a mobile client are described, thereby allowing mobile terminals to conserve battery life by more efficiently using resources such as the processor and transceiver in the mobile terminal A broker system may be used to minimize wireless communication traffic used for polling. A broker stub intercepts server polling messages at the client, multiplexes the sever requests together, and forwards the multiplexed message to a broker skeleton that de-multiplexes and forwards the messages as appropriate. Polling may also be dynamically adapted based on user behavior, or a server guard may be used to monitor changes to data, and notify a client to poll its respective server when the server guard detects new or updated data on that server for that client.
