摘要： A Global navigation satellite-based systems (GNSS) enabled device, handling at least two of a plurality of sensors, collects GNSS measurements and navigation related non-GNSS sensor data. The collected navigation related non-GNSS sensor data is automatically formatted into a data format that is compatible with a format of the GNSS measurements. The formatted navigation related non-GNSS sensor data and the GNSS measurements are utilized by a single function to compute navigation information for the GNSS enabled device regardless of sensor configurations such as a cellular radio and/or a motion sensor. Measurement errors in the collected navigation related non-GNSS sensor data is estimated to determine measurement accuracy. The collected navigation related non-GNSS sensor data is selectively adopted, combined with the GNSS measurements, to compute navigation information by the single function based on the determined measurement accuracy. The computed navigation information may be utilized to calibrate sensor and/or sensor data when needed.

摘要： A system and method for implementing a common control bus in a multi-regulator power supply integrated circuit. The integrated circuit may, for example, comprise first and second power regulator modules that control at least one characteristic of respective power signals. The integrated circuit may also, for example, comprise a communication interface module that receives power control information related to operation of the first and second power regulator modules over a shared data bus. An exemplary method may, for example, comprise receiving power control information over a data bus. The method may also, for example, comprise determining which of a plurality of power regulators corresponds to the received power control information. The method may further, for example, comprise determining a regulator control signal, based at least in part on the received power control information, and provide the regulator control signal to the determined regulator(s) to control operation of the determined regulator(s).

摘要： Methods and systems for mitigating latency in a data detector feedback loop are included. For example, a method for reducing latency in an error corrected data retrieval system is included. The method includes performing an analog to digital conversion at a sampling instant to create a digital sample, and performing a data detection on the digital sample to create a detected output. The detected output is compared with the digital sample to determine a phase error. During an interim period, the digital sample is adjusted to reflect the phase error to create an adjusted digital sample. After the interim period, the sampling instant is adjusted to reflect the phase error.

摘要： Cyclic shift delay (CSD) short training field (STF) for use within multiple user, multiple access, and/or MIMO wireless communications. Appropriately designed CSD STF is applied to communications in wireless communication systems thereby ensuring a minimized power error difference between respective portions of a packet transmitted therein. A first portion of the packet may be a short training field (STF) and a second portion of the packet may be a payload (e.g., a data portion). By applying such appropriately designed CSD STF to a packet, a wireless communication device that receives a signal corresponding to that packet need not perform extra or very significant backoff (e.g., with respect to a signal subsequent to automatic gain control (AGC) processing) thereby simplifying processing of that signal and potentially also reducing a total number of effective analog to digital converter (ADC) bits needed to represent a digitally sampled version of that signal.

摘要： A communications apparatus has a short range wireless radio frequency communicator (1301a) adapted to communicate wirelessly directly with another short range wireless radio frequency communicator in its vicinity to enable communication of at least one of power and data between the short range wireless radio frequency communicators and a high data rate data communicator (1301b) adapted to communicate directly with another high data rate data communicator to at least one of receive and transmit data when the short range wireless radio frequency communicator has communicated with another short range wireless radio frequency communicator.

摘要： Embodiments include antenna systems capable of producing high quality circularly, elliptically, or linearly polarized radiation. Embodiments include single feed (single-ended or differential) or multiple feed antennas. Embodiments can be electronically configured to adjust the type of polarization of the antenna system. In an embodiment, the polarization of the antenna system is adjusted by adjusting at least the position of a grounding node (302a-c) relative to the position of a feed node (106). In another embodiment, the polarization of the antenna system is adjusted by configuring one or more input nodes of the antenna between feed nodes, grounding nodes, and open nodes. In another embodiment, the polarization of the antenna system is adjusted by adjusting the phase of a single differential feed of the system.

摘要： Session recovery after network coordinator or AP restart for single user, multiple user, multiple access, and/or MIMO wireless communications. Restart or reset of a network coordinator (e.g., an access point (AP) or other network coordinator type device) may occur for various reasons (e.g., a power cycle or power failure, inadequate failover protection, scheduled or planned power outages such as for including network maintenance, software upgrades, etc.). Upon determination of network coordinator restarted or reset, a singular bit within a communication from the network coordinator indicates synchronization or not of the its timing synchronization function (TSF) (e.g., with other devices in the communication system, such as wireless stations (STAs), smart meter stations (SMSTAs), etc.). A given device (e.g., STA, SMSTA, etc.) can provide its current TSF to the network coordinator so that it can resynchronize, re-establish its scheduled for wake times of those devices (e.g., target wake times (TWTs)), etc.

摘要： An antenna circuit includes a substrate, an antenna, and a projected artificial magnetic mirror (PAMM). The antenna is fabricated on the substrate and is positioned in a region of the substrate that has a high permittivity. The PAMM produces an artificial magnetic conductor at a distance above a surface of the substrate to facilitate a radiation pattern for the antenna.

摘要： The disclosed systems and methods relate to improving PCI Express (PCI-E) L1 Active State Power Management (ASPM) exit latency by speculatively initiating early L1 exit based on a network stimulus. Aspects of the present invention may enable a higher level of performance and responsiveness while supporting the benefits of ASPM. Aspects of the present invention may minimize operational cost by reducing latency in processes that utilize a PCI-E interface. Aspects of the present invention may be embodied in a Network Interface Controller (NIC) or any other device with a PCI-E interface that supports ASPM.

摘要： Systems and methods are disclosed for supporting a pull data flow scheme in an AN decoder. One method relates to processing data using an AN decoder comprising receiving the data from a data stream and recovering a system time reference from the received data. The received data is processed using a clock asynchronous to the system time reference and pulled into an output device using a system adapted to support a pull data flow. The processed data is output using a time reference locked to the system time reference.
