  • Patent number: 10645776
    Abstract: A load control device may be configured to turn on lighting loads to obtain a fast turn-on time that may be substantially consistent across lighting loads that have different load voltages. The load control device may comprise a power converter circuit configured to produce a voltage across a capacitor, and a control circuit configured to control the power converter circuit to generate the voltage across the capacitor. The control circuit may determine a learned voltage from the magnitude of the voltage across the capacitor. For example, the control circuit may measure the magnitude of the voltage and store the measured voltage as the learned voltage. The control circuit may determine an operating parameter for the power converter circuit as a function of the learned voltage, and control the power converter circuit according to the operating parameter to charge the capacitor until the magnitude of the voltage exceeds a threshold.

  • Publication number: 20200065422
    Abstract: In one embodiment, a method includes accessing a document, identifying one or more noun phrases in the document by performing a pre-processing on the accessed document, generating, for each identified noun phrase, a list of candidate entities corresponding to the noun phrase, wherein the list of candidate entities is looked up in an entity index using the noun phrase, computing, for each candidate entity corresponding to each identified noun phrase, a confidence score that the noun phrase is intended to reference the candidate entity by analyzing the accessed document by a machine learning model, constructing a pool of mention-entity pairs for the accessed document, filtering the pool of mention-entity pairs by removing each mention-entity pair from the pool based on their computed confidence scores, and storing the post-filtered pool of mention-entity pairs in a data store in association with the accessed document.

  • Patent number: 10560244
    Abstract: Disclosed herein are systems, methods, and computer-readable storage devices for reducing inter-cellsite interference during full-duplex communication. A system receives a channel amplitude and a phase estimate between a first station and a second station, the first station and the second station creating inter-cellsite interference on a channel during full-duplex communications. The system calculates a level of the inter-cellsite interference between the first station and the second station based on the channel amplitude and the phase estimate and generates a cancellation signal based on the inter-cellsite interference. The system then communicates the cancellation signal to the first station for transmission with additional data during additional full-duplex communications.

  • Publication number: 20190215715
    Abstract: An eNodeB or other cell access point device can receive demand data from mobile devices served by the cell. The demand data can represent an estimate of demand over a future period for network resources (e.g., bandwidth). The cell can aggregate this demand data and determine price data for the time period or for various intervals of the time period, then transmit the price data to the mobile devices. The price data can operate as a collaborative approach to scheduling traffic. For example, data (e.g., delay tolerant data) can be shifted (e.g., delayed for a few seconds) based on an examination of the price data in conjunction a determined priority of the data. Such can be applicable to data traffic not traditionally thought of as delay tolerant such as streaming video or web browsing, and can be accomplished without negatively impacting the quality of service or experience of the client.

  • Publication number: 20190199965
    Abstract: Systems and techniques for enabling authentication for payment for an object associated with Augmented Reality (AR) object sharing between a first party and a second party include receiving, by a first party device, an input from the first party corresponding to a selection of an object. The techniques also include receiving, by the first party device, a request from the first party to the second party for approval of payment for the selected object. Furthermore, the techniques also include transmitting, by a network server to a second party device, the request for approval of the payment for the selected object. Moreover, the techniques include receiving, by the network server from the second party device, an authentication result including a determination by the second party of approval or rejection of payment for the selected object.

  • Publication number: 20190163836
    Abstract: In one embodiment, a method includes accessing a mention table of entries that each have: (1) a string, (2) a count of a number of times the string is used in a corpus, and (3) a count of a number of times the string is linked to another document. The method also includes calculating, for each n-gram of a search query from a querying user, a link probability that represents the likelihood that the n-gram corresponds to an entity associated with a communication network.

  • Patent number: 9655067
    Abstract: A method, a non-transitory computer-readable medium and an apparatus for receiving a data packet that is transmitted from a first sensor node are disclosed. For example, the method performs a channel scan of a particular burst of channel scans. When the preamble packet is detected, the method determines whether the preamble packet is addressed to the second sensor node. When the preamble packet is addressed to the second sensor node, the method sends an acknowledgement packet to the first sensor node. The method then receives the data packet that is transmitted from the first sensor node. The method then sleeps for a duration of time, when there is no packet transmission that is ongoing that is destined to the second sensor node.

  • Publication number: 20170061790
    Abstract: Vehicle-to-vehicle and vehicle-to-infrastructure communications are accomplished via a scalable ad hoc geographic routing protocol. As vehicles move along roadways, they can query other vehicles and entities for information. Responses to queries can be used to determine information such as traffic conditions, a retail store sale, that a restaurant has tables available, and/or that parking spaces are available, for example. Businesses, vehicles, and other entities along roadways can geocast pertinent information to vehicles passing by. Vehicles can cache information as it is received.

  • Patent number: 9210589
    Abstract: A protocol for providing location-based communication services in wireless sensor networks utilizes dynamic selection of forwarding devices, dynamic forwarding decisions, and intelligent backoff. Dynamic selection of forwarding devices limits the number of transmissions by dynamically selecting the devices that forward a message. Dynamic forwarding decisions implement different heuristics for different devices. According to intelligent backoff, devices that are closer to a destination region backoff for a shorter period of time than those which are further away from the destination region.

  • Patent number: 9104751
    Abstract: Systems, methods, and computer-readable storage media for presenting supplemental search results having indications that identified documents have been endorsed by the user and/or social network connections of the user are provided. A search query is received and it is determined that the user's social networking data is available. Documents that have been endorsed by the user and/or social network connections of the user are searched to identify those that satisfy the input search query. The satisfying documents are assigned a relevance score to determine whether each satisfying document is relevant enough to be shown and to determine placement of the document on the SERP relative to standard search results. Upon rendering of the SERP, a supplemental search result identifying documents that were endorsed by the user and/or social network connections of the user is presented, as is an indication about which social network connection(s) of the user endorsed the document.
