20140211677 | PRACH-BASED PROXIMITY DETECTION - Improvements to signaling procedures for use in physical random access channel (PRACH)-based proximity detection are disclosed. Signaling and signaling processes from a serving base station may trigger a more efficient and reliable transmission of PRACH from related user equipment (UE). At the dynamic power nodes (DPNs) monitoring for such PRACH-based proximity, features are disclosed which establish neighbor lists for more efficient management of detection and proximity activation. | 07-31-2014 |

20160072634 | HEADER COMPACTION FOR OPTIMIZED PROCESSING AND RETRANSMISSION OF TUNNELED MULTICAST DATA FOR AN EMBMS CLIENT DISTRIBUTED ARCHITECTURE - In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives an IP packet including header information and data for a MBMS session. The header information includes only information indicating at least one of an IP version, a destination multicast address of the IP packet, or a destination multicast port of the IP packet. The UE generates a multicast datagram including the data. The multicast datagram is generated based on at least one of the information indicating the destination multicast address or the information indicating the destination multicast port. The UE sends the multicast datagram to an application running on the UE. | 03-10-2016 |

20150234761 | ARBITRATING BUS TRANSACTIONS ON A COMMUNICATIONS BUS BASED ON BUS DEVICE HEALTH INFORMATION AND RELATED POWER MANAGEMENT - Devices, systems, methods, and computer-readable mediums for arbitrating bus transactions on a communications bus based on health information are disclosed. Health information of master devices can be used to adjust priorities of bus transactions from master devices to meet quality of service requirements of the master devices. In one embodiment, a bus interconnect is provided and configured to communicate bus transactions from any of a plurality of master devices to slave device(s) coupled the bus interconnect. The bus interconnect is further configured to map health information for each of the plurality of master devices into virtual priority space. The bus interconnect is further configured to translate the virtual priority space into a physical priority level for each of the plurality of master devices. The bus interconnect is further configured to arbitrate bus transactions for the plurality of master devices based on physical priority level for the plurality of master devices. | 08-20-2015 |
20150286467 | SYSTEM AND METHOD FOR ADAPTIVE COMPRESSION MODE SELECTION FOR BUFFERS IN A PORTABLE COMPUTING DEVICE - Systems and methods for adaptive compression mode selection for memory buffers such as those used in or with a portable computing device (“PCD”) are presented. During operation of the PCD a first compression mode is selected for a buffer and the buffer is formatted to the first compression mode. Any access to the buffer by a component of the PCD, core of the PCD or software application running on the PCD is monitored. Based on the amount and/or type of access to the buffer, a second compression mode for the buffer is selected. The buffer is formatted to the second compression mode, providing a cost effective ability to adaptively format buffers based on the component(s), cores(s), and/or software application(s) accessing the buffers, and allowing for improving or optimizing bandwidth, memory footprint, resource conflict, power consumption, latency, and/or performance of component(s), core(s), or software application(s) accessing buffers as desired. | 10-08-2015 |
20150302903 | SYSTEM AND METHOD FOR DEEP COALESCING MEMORY MANAGEMENT IN A PORTABLE COMPUTING DEVICE - Various embodiments of methods and systems for deep coalescing memory management (“DCMM”) in a portable computing device (“PCD”) are disclosed. Because multiple active multimedia (“MM”) clients running on the PCD may generate a random stream of mixed read and write requests associated with data stored at non-contiguous addresses in a double data rate (“DDR”) memory component, DCMM solutions triage the requests into dedicated deep coalescing (“DC”) cache buffers, sequentially ordering the requests and/or the DC buffers based on associated addresses for the data in the DDR, to optimize read and write transactions from and to the DDR memory component in blocks of contiguous data addresses. | 10-22-2015 |
20160098813 | TRANSPARENT PIXEL FORMAT CONVERTER - A transparent format converter (TFC) may determine that a request by at least one processor for graphics data stored in graphics memory is indicative of a request for graphics data in a first data format. The TFC may retrieve the graphics data in a second data format from the graphics memory based at least in part on the request for the graphics data in the graphics memory. The TFC may convert the retrieved graphics data from the second data format to the first data format. The TFC may store the converted graphics data in the first data format into a memory that is accessible by the at least one processor. | 04-07-2016 |

20150069939 | CIRCUITS AND METHODS FOR DRIVING RESONANT ACTUATORS - The present disclosure includes circuits and methods for driving resonant actuators. In one embodiment, a drive signal is applied to an actuator during a portion of a plurality of half cycles of a period of the drive signal. The actuator has a resonant frequency and may vibrate in response to the drive signal. An induced voltage is generated on terminals of the actuator in response to the vibration. A detection circuit may detect when the induced voltage on the actuator crosses a threshold after the drive signal is turned off. The drive signal may be triggered based on when the induced voltage crosses the threshold to align a frequency and phase of the drive signal with the resonant frequency and a phase of the actuator. | 03-12-2015 |
20150263614 | AVERAGE CURRENT MODE CONTROL OF MULTI-PHASE SWITCHING POWER CONVERTERS - Exemplary embodiments are related to switching power converters. A switching power converter may comprise a plurality of control unit configured for average current mode control, wherein each control unit of the plurality comprises a dedicated proportional control unit. The switching power converter may further comprise an integrator coupled to each control unit of the plurality of control unit and configured to convey a signal to each control unit. | 09-17-2015 |
