  • Dynamic antenna switching
    Patent number: 9231686
    Abstract: Dynamic antenna switching based on weighted signal to noise ratio (SNR). A wireless device may include multiple antennas. SNR at each active antenna may be calculated. An antenna-specific weight may be applied to each antenna's SNR. The antenna-specific weights may further be radio specific and/or transmit or receive specific in some cases. Antenna selection (possibly just for a specific radio and/or for transmit or receive operations, depending on the specificity of the antenna weights), including potentially switching which antenna is used, may be based on the resulting weighted SNR values for each antenna. If the antenna-specific weights are radio specific and/or transmit or receive operation specific, the method may be performed multiple times with different antenna-specific weights to select antenna(s) for different radios and/or for other operations.

  • Chemical conversion coating for protecting magnesium alloys from corrosion
    Patent number: 9228263
    Abstract: A chromate-free, self-healing conversion coating solution for magnesium alloy substrates, composed of 10-20 wt. % Mg(NO3)2.6H2O, 1-5 wt. % Al(NO3)3.9H2O, and less than 1 wt. % of [V10O28]6? or VO3? dissolved in water. The corrosion resistance offered by the resulting coating is in several hundreds of hours in salt-spray testing. This prolonged corrosion protection is attributed to the creation of a unique structure and morphology of the conversion coating that serves as a barrier coating with self-healing properties. Hydroxoaluminates form the backbone of the barrier protection offered while the magnesium hydroxide domains facilitate the “slow release” of vanadium compounds as self-healing moieties to defect sites, thus providing active corrosion protection.

  • IC DESIGN SYNTHESIS USING SLACK DIAGRAMS
    Publication number: 20150379175
    Abstract: An updated integrated circuit (IC) design is generated by applying a histogram-based algorithm to an invalid, current IC design. The histogram-based algorithm includes worst negative slack (WNS) optimization followed by total negative slack (TNS) optimization. WNS optimization uses the slack histogram for the current IC design to generate an invalid, but improved, intermediate IC design. TNS optimization uses the slack histogram of the intermediate IC design to generate the updated IC design.

  • DISTRIBUTED KEY-VALUE STORE
    Publication number: 20150379009
    Abstract: Techniques are disclosed for managing a high performance, fault-tolerant, strongly consistent, distributed key-value store system. The key-value store may store information, such as metadata for a distributed file system. Fault-tolerance means that the distributed key-value store continues to provide access to values in the key-value store in spite of a certain number of node failures. To provide this capability, the key-value store may store copies of (key, value) pair on N+1 nodes in order to provide fault tolerance for the failure of up to N nodes. In addition, metadata describing which nodes store a given value is stored on 2N+1 nodes and the distributed key-value store is sized such that there are 3N+1 nodes in a cluster. Doing so allows the key, value store to tolerate a failure of N nodes, while still maintaining a consistent and available key-value store.

  • MAKING MORE ACTIVE USE OF A SECONDARY STORAGE SYSTEM
    Publication number: 20150370502
    Abstract: Techniques are disclosed which allow a secondary storage system to provide data to non-production workloads in conjunction with performing data backup and protection tasks. As disclosed, a secondary storage system exposes backup data stored by the secondary storage system to other workloads, such as test and development applications, data analytics, etc. These non-production workloads can run at the same time the secondary storage system provides backup services to a primary storage system. This consolidation eliminates the need for an enterprise to deploy separate storage clusters for analytics, test and development applications, etc. and eliminates unnecessary copies of data.

  • Systems and methods for minimizing power dissipation in a low-power lamp coupled to a trailing-edge dimmer
    Patent number: 9215772
    Abstract: A controller may predict an estimated occurrence of a high-resistance state of a dimmer, wherein the high-resistance state occurs when the dimmer begins phase-cutting an alternating current voltage signal. The controller may also be configured to operate in a trailing-edge exposure mode for a period of time wherein the period of time includes a time of the estimated occurrence of the high-resistance state in order to allow the controller to detect the occurrence of the high-resistance state, wherein energy is transferred from an input to a dissipative element during the trailing-edge exposure mode. The controller may further be configured to minimize a time between a beginning of the period of time and the estimated occurrence of the high-resistance state by modifying the period of time based on an estimated charging time of a capacitor of the dimmer.

  • Systems and methods for valley switching in a switching power converter
    Patent number: 9214862
    Abstract: A controller may be configured to generate a control signal to activate and deactivate a switch of a switching power converter in order to control a switching period and a peak current of the switching power converter to maintain a regulated current of the switching power converter at a desired current level such that: if the switching period decreases below a minimum switching period, the controller increases the switching period by a ringing period of a voltage of the switch and increases the peak current to compensate for the increase of the switching period in order to maintain the regulated current, and if the peak current increases above a maximum peak current, the controller decreases the switching period by a ringing period of the voltage of the switch and decreases the peak current to compensate for the decrease of the switching period in order to maintain the regulated current.

  • Dimmer detection
    Patent number: 9207265
    Abstract: In at least one embodiment, a lighting system receives an input signal, such as a supply voltage, that can be affected by a dimmer. The supply voltage can be affected by a dimmer when, for example, a dimmer phase cut (i.e. chopped) the supply voltage. A dimmer detection system of the lighting system determines if a dimmer is affecting the supply voltage. In at least one embodiment, the dimmer detection system also determines a type of the dimmer, such as detecting if the dimmer is a leading edge or trailing edge dimmer. In at least one embodiment, the dimmer detection system provides dimmer type data to one or more other circuits such as a switching power converter controller. The one or more other circuits utilize the dimmer type data to affect their operation.
