  • Patent number: 10924541
    Abstract: An enumeration technique is provided that requires no pre-assignment of addresses to slave devices connected through P2P links to a host device. With regard to any P2P link between devices, one device has a master interface and the remaining device has a slave interface. To distinguish between the master and slave interfaces, a master/slave status bit may be used. Each P2P link has a link ID that may be concatenated with the status bit for a corresponding interface (slave or master) to form a node ID. The host device receives a unique concatenated address from each slave device that represents a concatenation of the node ID for the slave and the node ID for any intervening interfaces between the slave device and the host device. The host device then assigns a unique Cartesian address to each slave device.

  • Patent number: 9990317
    Abstract: Systems, methods, and apparatus for data communication are provided. An apparatus maybe configured to generate a mask field in a packet to be transmitted through an interface to a slave device, the mask field having a first number of bits, provide a control-bit field in the packet, the control-bit field having a second number of bits, where the second number of bits is less than the first number of bits, and transmit the packet through the interface. The packet may be addressed to a control register of the slave device. The control register may have the first number of bits. Each bit in the control-bit field may correspond to a bit of the control register that is identified by the mask field.

  • Patent number: 9955325
    Abstract: A system may include a sensor system and a control system configured for communication with the sensor system. The sensor system may include an ultrasonic sensor system. The control system may be capable of determining, based at least in part on signals from the ultrasonic sensor system, whether a personal medical device is within a predetermined distance from the mobile device. The control system may be capable of adjusting one or more mobile device settings in response to a determination that the personal medical device is within the predetermined distance of the mobile device.

  • Patent number: 9877308
    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a broadcast multimedia receiver device. The apparatus detects a signal causing interference at a first radio of the receiver device. The first radio is configured to receive broadcast multimedia transmissions. The apparatus determines a RAT associated with an aggressor entity transmitting the signal. The aggressor entity is physically remote from the receiver device. The apparatus determines a mitigation action to mitigate the interference caused by the signal at the first radio. The apparatus transmits, at a second radio of the receiver device, a control message to the aggressor entity. The control message instructs the aggressor entity to implement the mitigation action. The second radio is configured to communicate with the aggressor entity using at least one RAT or a wired interface.

  • Publication number: 20170118125
    Abstract: Methods and apparatuses are described that facilitate the communication of data between a transmitter and a receiver across a serial bus interface. In one configuration, a transmitter generates a datagram based on a register address, detects whether the register address is within a high data rate (HDR) access address range, and sends a payload of the datagram to the receiver according to a HDR mode when the register address is within the HDR access address range. In another configuration, the transmitter generates a datagram including at least a command field and a data field, sends the command field to the receiver according to a single data rate (SDR) mode, wherein the command field indicates a transition to a high data rate (HDR) mode for sending the data field, and sends the data field to the receiver according to the HDR mode.

  • Publication number: 20170116141
    Abstract: Methods and apparatuses are described that facilitate the communication of data between a transmitter and a receiver across a serial bus interface. In one configuration, a transmitter generates a datagram based on a 16-bit address and a mask-and-data pair burst length, the 16-bit address including a most significant byte (MSB) and a least significant byte (LSB), compares the MSB to a receiver base address maintained in a shadow register, compares the mask-and-data pair burst length to a receiver masked-write burst length maintained in the shadow register, and sends the datagram to the receiver via the bus interface when: the MSB is equal to the receiver base address maintained in the shadow register, and the mask-and-data pair burst length is equal to the receiver masked-write burst length maintained in the shadow register.

  • Publication number: 20170070971
    Abstract: Disclosed are systems, methods and techniques for determining or inferring a status or fault for a portion or aspect of a global navigation satellite system (GNSS). For example, fault messages may be received from multiple mobile devices where fault messages provide indicators indicative of events or conditions. Fault indicators in received fault messages obtained from messages received from two or more of the mobile devices may be combined to infer a status or fault of at least a portion of a GNSS. Augmentation parameters conveying information related to an inferred fault may be transferred to a mobile device to improve GNSS location of the mobile device.
