20150044977 | METHOD AND WIRELESS COMMUNICATION DEVICE FOR USING AN ANTENNA AS A SENSOR DEVICE IN GUIDING SELECTION OF OPTIMIZED TUNING NETWORKS - A method and system performs antenna tuning using detected changes in antenna self-capacitance in a wireless communication device. A modem detects changes in antenna self-capacitance by utilizing multiple antenna elements. The modem determines a current antenna loading condition using the detected changes in antenna self-capacitance. The modem determines appropriate tuning states for each antenna matching and tuning circuit (AMTC) associated with a respective antenna element. In order to determine the appropriate tuning states, the modem utilizes pre-established antenna self-capacitance information which is mapped to antenna tuning states. The antenna tuning states which are respectively mapped to pre-established antenna self-capacitance are empirically pre-determined by correlating antenna self-capacitance changes to antenna impedance changes. The modem is thus able to change the tuning states of multiple tunable matching circuits and perform antenna tuning using (a) detected real-time changes in antenna self-capacitance and (b) pre-established mappings of antenna self-capacitance and antenna tuning states. | 02-12-2015 |

20100208712 | Enhancing WLAN performance in the presence of interference - A wireless access point coherently receives signals transmitted from client devices and from interfering devices, measures noise and interference capture samples from the received signals, and computes a characterization of noise plus interference. Receive gains and threshold levels are adjusted based on the computed noise plus interference characterization. A set of weights for an interference suppression spatial filter are calculated from the measured noise and interference capture samples and used to produce a filtered signal by spatially filtering the received signals such that interference is spatially nulled in the filtered signal. The method may also include setting PHY parameters at the wireless access point based on the computed noise plus interference characterization. In some embodiments, a protection transmission is transmitted from the wireless access point, requesting connected client devices to suspend transmissions during a specified time period. | 08-19-2010 |

20140240607 | POWER STATE MANAGEMENT FOR SET-TOP BOXES - When a set-top box determines to enter a low-power state, the set-top box determines a wake-up time based on a recording schedule, a maintenance schedule, and a boot spread. Before transitioning to the low-power state, the set-top box sends a message to a schedule server with the wake-up time. The server provides services to many set-top boxes. The server uses a wake-up time schedule that includes the wake-up times for the set-top boxes that it services to determine if the wake-up time will create too much load for the server given the set-top boxes already scheduled to wake-up around the wake-up time. If the proposed wake-up time will not create too much load, the server may respond to the set-top box that the proposed wake-up is acceptable. If not, the server may propose a new wake-up time based on the schedule. | 08-28-2014 |
