Abstract: A fuel pump system for aircraft includes an auxiliary fuel pump in-line with the primary pump, and an electric motor driving the auxiliary fuel pump at an operational motor speed. The system includes an electric control circuit (ECC) and a pressure sensor to regulate the speed of the electric motor based on the output pressure from the sensor to maintain a constant predetermined output pressure. The system may have additional fault mitigation circuitry configured to automatically switch from a processor-controlled to a fixed voltage as a source of power driving the electric motor at either a regulated speed or a constant fixed speed, respectively. The system may include a switch having user-selectable operational modes, including ECC-controlled mode and a high boost mode selectable if the ECC fails. In high boost mode, the ECC is bypassed to drive the electric motor at a fixed safe speed.

Abstract: Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases.

Abstract: An earbud is disclosed for use in a user's ear. The earbud includes an ear pad shaped to engage the concha of the ear and an audio driver coupled to the ear pad. When the earbud is installed in the user's ear the ear pad substantially occludes, or closes up the concha of the user's ear. Thus ambient noise is significantly attenuated before reaching the user's ear canal. Also, the earbud is supported primarily by the ear pad resting in the concha.
