  • Server-assisted device-to-device discovery and connection
    Patent number: 9654960
    Abstract: A method includes receiving, at a network node, a device-to-device D2D discovery request from a first device and sending a D2D discovery response from the network node to the first device. The D2D discovery response includes information associated with a second device that is available to establish a D2D connection with the first device. The network node may perform inquiries regarding D2D connection permission from both devices. If D2D connection is permitted by both devices, the network node may facilitate the D2D scanning by sending each device's scanning information to the other device via a non-D2D link. In parallel to D2D scanning, the network node may speed up D2D link setup by distributing, via non-D2D links, link setup information to each device, where the link setup information may include device credential(s), IP address allocation(s), and/or group owner assignment.

  • Segmented resistor digital-to-analog converter with resistor recycling
    Patent number: 9654136
    Abstract: Embodiments relate to an improved segmented resistor digital-to-analog converter (DAC) with resistor recycling. An input digital code word is segmented into M most-significant-bits (MSBs) and N least-significant-bits (LSBs). The DAC includes a MSB resistor ladder coupled with a first set of switches and a LSB resistor ladder coupled with a second set of switches. Based on the decoded bit pattern of the LSBs, embodiments are operable to either switch one or more LSB resistors from the bottom of the MSB resistor ladder up to the top, or to switch the LSB resistors from the top of the MSB resistor ladder down to the bottom. In at least one example embodiment, this technique can avoid redundant resistors in the circuit, which can solve mismatch problems due to redundant resistors in the circuit as in prior art solutions, which can lead to problems relating to non-linearity and non-monotonicity.

In one example, a video coder is configured to determine, for a block of video data, a set of most probable intra-prediction modes such that the set of most probable intra-prediction modes has a size that is equal to a predetermined number that is greater than or equal to two. The video coder is also configured to code a value representative of an actual intra-prediction mode for the block based at least in part on the set of most probable intra-prediction modes and code the block using the actual intra-prediction mode. The video coder may further be configured to code the block using the actual intra-prediction mode, e.g., to encode or decode the block. Video encoders and video decoders may implement these techniques.
