Abstract: 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.

Abstract: In a disclosed embodiment, a system includes a digital imaging device, an electronic compass (e-compass), and a processor coupled to the digital imaging device and the e-compass. The processor is operable to execute instructions that cause the image device to scan a visual code, read a yaw angle from the visual code, cause the e-compass to obtain magnetic field measurements, estimate a yaw angle based on the magnetic field measurements, compare the yaw angle read from the visual code and the estimated yaw angle to determine a quality factor; and determine whether the e-compass is calibrated based at least partially upon the quality factor.

Abstract: Methods of reducing power consumption in a USB power-delivery source device. In one such method, one or more source capabilities messages are sent by the USB power-delivery source device. If, after sending a source capabilities message, a response to said source capabilities message is not received within a predetermined time period, the device sends another source capabilities message. If, after sending a predetermined number of source capabilities messages, no response is received, the device waits an extended period of time before sending another source capabilities message. Receiving functionality of the USB power-delivery source device is turned off during some or all of said extended period of time.
