Abstract: During operation, an access point may receive, associated with other access points, information specifying one or more communication-performance metrics associated with the shared band of frequencies. Then, based at least in part on the one or more communication-performance metrics, the access point may determine a proposed channel and/or a proposed channel width for use by the access point during communication in a shared band of frequencies. Moreover, the access point may provide, addressed to the other access points, second information specifying the proposed channel and/or the proposed channel width. Next, the access point may receive, associated with the other access points, feedback about the proposed channel and/or the proposed channel width. Furthermore, based at least in part on the feedback, the access point may select a channel and/or a channel width for use by the access point during communication in the shared band of frequencies.

Abstract: During operation, a computer system may receive, associated with an access point, connection information, where the connection information indicates that an electronic device is currently associated with the access point in a wireless network. Then, the computer system may access information specifying historical behavior of the electronic device in the wireless network. Moreover, based at least in part on the historical behavior of the electronic device, the computer system may predict future roaming of the electronic device in the wireless network, where the predicted future roaming includes a prediction that the electronic device will establish a connection with a neighbor access point in the wireless network. Next, the computer system may provide, addressed to the neighbor access point, at least a portion of an encryption key(s) associated with a current connection between the access point and the electronic device.

Abstract: The systems and methods for hang correction in a power management interface bus cause secondary master devices associated with the power management interface bus to utilize timers to determine if a master that won arbitration has asserted a clock signal within a predefined amount of time. If a timer for a secondary master device expires without a clock signal being asserted by the winning master, the secondary master will assume ownership of the bus and assert a clock signal. Priorities between secondary masters are created by using a master identification (MID) value assigned during bus enumeration to determine a timer value. By allowing the secondary masters to assume ownership after expiration of respective timers, bus ownership is maintained in the event that a winning master hangs and does not assert ownership.

Abstract: Nested commands for a radio frequency front end (RFFE) bus are provided. In particular, timing commands may be nested inside a normal data flow. On receipt of a nested timing command, a slave on the RFFE bus suspends or halts an active command and addresses the timing command. On completion of the timing command, the slave returns to the halted command. By allowing such nested commands, counters in the slave that would otherwise be used to track triggers may be eliminated or reduced and power may be conserved by placing a clock signal associated with the bus into a low power mode.

Abstract: Apparatus for homogeneously intermixing flows of fuel and air to an internal combustion engine comprises a mixing chamber having a venturi portion across which is disposed an arcuate nozzle-matrix of converging nozzle cells which focus subflows toward pre-selected downstream crossflow mixing zones. A mainstream flow of air is introduced into the chamber upstream of the nozzle-matrix and one or more mainstream flows of fuel are introduced into the chamber upstream of the nozzle-matrix and/or into the crossflow mixing zones. The nozzle-matrix is adapted to accept at least portions of the main upstream flows to generate several optimum velocity subflows therefrom to enhance fuel and dispersion, atomization, and vaporization into the air.
