  • Patent number: 9543030
    Abstract: Methods and systems for sensing memory cells using a sense amplifier that can support both ramp sensing and conventional sensing are described. With ramp sensing, a word line of a memory array may be ramped up linearly and a sensing operation may be performed by the sense amplifier while the word line is continuously being ramped up. In this case, during the sensing operation, the sense amplifier may sense a bit line of the memory array connected to a memory cell while the word line is ramping up and then transfer the result into a data latch. In contrast, with conventional sensing, a bit line of the memory array may be first precharged to a particular voltage level (e.g., a read voltage level) and then sensed while the word line is held at the particular voltage level.

  • Publication number: 20160378891
    Abstract: Disclosed is a method for real-time prediction of thermal-insights for a heat dissipating device in a data center cooled by one or more cooling units. The method uses a concept of influence mass fractions in conjunction with proper orthogonal decomposition (POD) based reduced order model. It may be understood that, the influence mass fractions may be computed by performing a fixed number of CFD simulations based on mass flow rates of the one or more cooling units. The method further facilitates to identify a set of reference scenarios for a given range of operational parameters of the one or more cooling units impacting the heat dissipating device. The set of reference scenarios may then be provided to the POD in order to predict the thermal-insights of the data center such as a temperature, mass flow rate, and insights into thermal influence of air sources on the heat dissipating device.

  • Publication number: 20160371534
    Abstract: Architecture that enables the identification of entities such as people and content in live broadcasts (e.g., streaming content (e.g., video) of live events) and non-live presentations (e.g., movies), in realtime, using recognition processes. This can be accomplished by extracting live data related to a live event. With respect to people entities, filtering can be performed to identify the named (people) entities from the extracted live data, and trending topics discovered as relate to the named entities, as associated with the live event. Multiple images of the named entities that capture the named entities under different conditions are captured for the named entities. The images are then processed to extract and learn facial features (train one or more models), and facial recognition is then performed on faces in the video using the trained model(s).

  • Publication number: 20160360470
    Abstract: An access point that implements operating modes in which beacons may be selectively disabled. Beacons may be disabled when no device is actively associated through the access point. Beacons may be enabled in response to one or more triggers, which may include events such as a client forming an association through the access point following a probe request message identifying the access point. In addition, active beaconing may be triggered by user input or may occur during periodic brief intervals that allow client devices to discover the network identifier for the access point. Selective control of beaconing may lead to more effective wireless communication, particularly in areas where users congregate with computers implementing soft APs for personal networks.

  • Publication number: 20160322093
    Abstract: Non-volatile flip-flops (NVFFs) based circuitries and schemes that incorporate magnetic tunnel junctions (MTJs) are provided to ensure fast data storage and restoration from an intentional or unintentional power outage. The NVFFs based circuitries and schemes also include enhanced scan mode testing capability by exploiting the nonvolatile latch to function as hold latch for delay testing. The NVFFs based circuitries and schemes eliminate additional write drivers, and may operate at an operation frequency of, for example, up to 2 GHz at a supply voltage of 1.1 V and with 0.55 pJ of energy consumption. A near uniform write latency can be achieved through transistor sizing, given write asymmetry of MTJs. NVFFs based circuitries and schemes incorporating data-dependent power gating circuitries can be used to mitigate high static currents generated during retention and back-to-back writing of identical input data.
