  • Patent number: 10405369
    Abstract: A slave Bluetooth device establishes first and second connections with first and second master Bluetooth devices, respectively, that each operate in a master mode. The slave Bluetooth device operates in a slave mode when communicating through any of the first and second connections. The slave Bluetooth device communicates connection parameter update request packets containing timeout values to the first and second master Bluetooth devices. The slave Bluetooth device alternates during non-overlapping time slots between at least: 1) monitoring the first connection for traffic transmitted by the first master Bluetooth device while not monitoring the second connection; and 2) monitoring the second connection for traffic transmitted by the second master Bluetooth device while not monitoring the first connection; and controls a rate at which the alternating is performed based on the first timeout value and the second timeout value.

  • Patent number: 10257161
    Abstract: Neighbor discovery is used to create a generic trust database for other applications. As part of the neighbor discovery, each device performs classification and validation of the credentials of the neighboring devices. The credentials and validation results are stored locally without having to perform a separate authentication step. The trust database is created and maintained as a neighbor table with the results of the validation. The generic trust database may then be consulted by other protocols. The neighbor discovery may use any of various underlying protocols, but the resulting table unifies the results such that other applications or protocols may take advantage of the secured identity without having to implement their own discovery process. Both discovery and validation may be implemented locally without relying on centralized servers. Manual configuration may be avoided.

  • Patent number: 9654545
    Abstract: Embodiments described herein involve selecting a group coordinator device for a group of media devices of a networked media playback system. One of the media devices in the networked media playback system may be a group coordinator device configured to provide media content and playback timing information to other media devices in the group for synchronized playback of media content. Selection of the group coordinator device may involve performing an evaluation of one or more parameters associated with each of the one or more media devices in the media playback system, determining that a particular media device is the most suitable group coordinator devices, and causing the particular media device to become the group coordinator device.

  • Patent number: 9635059
    Abstract: An adaptable network security system includes trust mediator agents that are coupled to each network component. Trust mediator agents continuously detect changes in the security characteristics of the network and communicate the detected security characteristics to a trust mediator. Based on the security characteristics received from the trust mediator agents, the trust mediator adjusts security safeguards to maintain an acceptable level of security. Trust mediator also uses predetermined rules in determining whether to adjust security safeguards. Despite inevitable changes in security characteristics, an acceptable level of security and efficient network operation are achieved without subjecting users of the network to over burdensome security safeguards.

  • Patent number: 9622112
    Abstract: A radio communication method stores a plurality MAC frames for each of a plurality of destinations. The method decides the longest transmission time of transmission times needed to transmit the plurality of MAC frames to each of the plurality of destinations within a fixed period. The method generates a plurality of physical frames for the plurality of destinations to transmit them at the same time by connecting the plurality of MAC frames and adding additional information to each connected MAC frame so as to be a frame length equivalent to a transmission time equal to the longest transmission time.

  • Patent number: 9603106
    Abstract: The disclosure provides for reducing uplink control channel overhead at a user equipment (UE). The UE may determine that a total transmit power of the UE exceeds an allocated power. The UE may then scale a transmit power of a high-speed dedicated physical control channel (HS-DPCCH) relative to a dedicated physical control channel (DPCCH) in response to the determination that the UE is power limited. The UE may scale the transmit power of the HS-DPCCH when there is no downlink activity as determined, for example, by expiration of a timer. In an aspect, the UE may transmit an indication that the UE is power limited, for example, by using a most-significant bit of a transport format combination index. In another aspect, the UE may receive an indication that a downlink transmission is imminent and, in response, the UE may transmit the HS-DPCCH without scaling its corresponding transmit power.

  • Patent number: 9547466
    Abstract: A graphical user interface (GUI) is polled to identify updates for transmission to a client device. A generalized poll of the GUI is conducted at a first frequency, wherein the poll compares color values of each pixel in a general region of the GUI with a previously known color value for that pixel to detect changed pixel color values. A local region that is a subset of the general region is determined to have a greater likelihood of being updated, e.g., regions encompassing a location of mouse and/or keyboard activity. A localized poll is conducted at a second frequency of only the local region of the GUI.

  • Patent number: 9516688
    Abstract: A method includes attaching to a Packet Data Network (PDN) supporting services over a long term evolution (LTE) network to establish a first network connection. The method includes connecting to a wireless local area network, e.g. a WiFi network, to establish a second network connection. The method further includes launching an application accessing at least one of the supported services and receiving a request from the application to switch between the first and second network connections, according to the supported service, e.g. a policy associated with the service. Switching from the first network connection to the second network connections includes connecting to the PDN via an evolved Packet Data Gateway (ePDG).

  • Patent number: 9515803
    Abstract: A user equipment receives configuration information from a base station in a wireless communication system. Radio signals carrying configuration control information are received by a user equipment (UE) that includes an ACK/NACK feedback mode indicator. The UE also receives downlink subframes. The ACK/NACK feedback mode indicator is processed to determine if the ACK/NACK feedback mode indicator indicates the user equipment should (a) send an ACK/NACK signal in a one-to-one mapping between a downlink subframe and a corresponding uplink ACK/NACK signal or (b) send an ACK/NACK signal in an N-to-one mapping between N downlink subframes, where N is an integer greater than one, and a corresponding single uplink ACK/NACK signal. One or more ACK/NACK signals is transmitted in accordance with the determination of the processor.
