    摘要： Methods and apparatus for operating a communication system comprising three or more communication transceivers. In illustrative embodiments, multiple unique start-of-packet delimiters are maintained. A data packet to be transmitted is constructed using a specified one of the plurality of start-of-packet delimiters to demarcate the start of said data packet. The chosen start-of-packet delimiter reflects one or more transceivers that are intended recipients of said data packet. When a data packet is received by a transceiver, the start-of-packet delimiter of the received data packet is compared to one or more valid start-of-packet delimiters for the receiving transceiver. If the start-of-packet delimiter of the received data packet matches a valid start-of-packet delimiter for the receiving transceiver, the data packet is accepted, otherwise it is rejected.

    摘要： A wireless device for indoor positioning has a satellite positioning system, a transceiver, a motion measurement system, and a position estimation system. The satellite positioning system is configured to determine a location of the device based on received satellite positioning signals. The wireless local area network transceiver is configured to measure while in the areas of non-reception, signals transmitted by wireless local area network (WLAN) access points (APs). The motion measurement system is configured to measure movement of the wireless device. The position estimation system is configured to determine a reference location, and record measurements of movement. The reference location and the recorded measurements are to be provided to a positioning database that generates a positioning grid.

    摘要： An electronic system includes a computer and a power adapter. The computer includes an embedded controller (EC) coupled to a computer power delivery (PD) controller. The power adapter includes a power adapter PD controller connected to a slave device and is configured to communicate with the computer over a communication link. The computer PD controller is configured to receive a command from the EC and, to transmit a universal serial bus (USB) vendor defined message (VDM) header and one or more vendor defined objects (VDOs) including the information of the payload of the transmit command. The power adapter PD controller responds to the one or more VDOs either by changing an output signal to the slave device connected to the power adapter PD controller, reports a state of a general purpose input/output (GPIO) pin of the power adapter PD controller, or changes the state of the GPIO pin.

    摘要： Visual codes are scanned to assist navigation. The visual code may be a Quick Response (QR) code that contains information useful to calibrating a variety of navigation-based sensors such as gyroscopes, e-compasses, and barometric pressure sensors. In an embodiment, an imaging device, an e-compass, an accelerometer, and a processor are elements of a system. The processor is coupled to the imaging device, the e-compass, and the accelerometer. The processor causes the imaging device to scan a visual code, read a yaw angle from the visual code, and computes an estimate of a yaw angle based on magnetic field measurements taken by the e-compass. The processor generates scale factors and biases determined from measurements generated by the e-compass. Based on scanning the visual code, the processor computes a quality factor based on the yaw angle read from the visual code and the estimate of the yaw angle.

    摘要： A wireless device that includes an access point (AP) scanner, a transceiver, and a controller coupled to the AP scanner and transceiver. The AP scanner is configured to scan wireless network channels utilized by one or more APs to transmit data packets, probe responses, and beacons. The transceiver is configured to transmit one or more probe requests to the one or more APs and receive one or more probe responses and beacons from the one or more APs. The controller is configured to determine a proximate geographic position of the wireless device based on signal strength of the one or more probe responses and beacons received from the one or more APs. The controller also dynamically adapts a parameter utilized in determining the proximate geographic position of the wireless device.
