摘要： Methods and systems for location determination using structural visual information may comprise receiving global navigation satellite system (GNSS) signals in a wireless device (WD) for determining a first position of the WD. One ore more images of a structure or structures near the WD may be captured and a position may be determined based on a comparison of the structures in the images to structures in a stored database. The database may be pre-stored based on a known future location of a user of the WD. The database may be downloaded and stored when insufficient GNSS signals are present. The database may comprise a plurality of images or may comprise video of structures. A distance from the structures may be determined based on known optical properties of a camera in the WD, and may be used to determine an accurate location based on the images.

The GTOD clock may comprise a GPS clock, a GLONASS clock, and/or a Galileo clock. One or more of the networked devices may comprise a network controller, where the network controller comprises wireless network and wired network capability.

摘要： A radio integrated circuit includes, in part, an analog front end block, an analog-to-digital converter responsive to the analog-front end block, a digital signal processor responsive to the analog-to-digital converter and adapted to generate in-phase and quadrature signals, and a serial communication interface configured to receive and transmit the in-phase and quadrature signals. The serial communication interface supplies a gain control signal to the analog front end block when a switch disposed in the radio integrated circuit is in a first position. When the switch is in a second position, a gain control block disposed in the radio integrated circuit receives a gain control signal from the analog-to-digital converter and supplies the gain control signal to the analog front end block. The digital signal processor may be configured to interleave the in-phase and quadrature signals.

摘要： An Internet protocol low noise block downconverter (IP LNB) assembly, which is within a satellite dish assembly, may be operable to determine one or more baseline settings of the satellite dish assembly. The IP LNB assembly may monitor, periodically or aperiodically, one or more current settings that may correspond to the determined one or more baseline settings to identify deviations of the one or more current settings from the baseline settings. The results of the monitoring may be communicated to a satellite service provider. The satellite service provider may provide maintenance and/or service management for the satellite dish assembly based on the communicated results of the monitoring. The IP LNB assembly may determine a location setting via a GNSS module and determine an alignment setting via a directional sensor in the IP LNB assembly. The IP LNB assembly may determine a received signal strength based on a RSSI.

摘要： A network device (e.g., a cable modem) may support a normal mode of operation and a sleep mode of operation. While in the normal mode, a PHY of the network device may process a received signal to recover MPEG-TS packets, and convey the MPEG-TS packets to other components of the network device for further processing. While in the sleep mode, the PHY may process received MPEG-TS packets having a particular packet identifier and drop received MPEG-TS packets not having the particular packet identifier. The PHY may control transitions between the normal mode and the sleep mode in response to received signals having particular physical layer characteristics. The PHY may demodulate a received signal to recover an MPEG-TS packet; descramble portions of the MPEG-TS packet; inspect portions of the MPEG-TS packet; and control a mode of operation of the network device based on the contents of the MPEG transport stream.
