Abstract: A method of joining a wing to an aircraft fuselage by forming a series of pinned lug joints between a fuselage side and a wing side of a wing box structure. The joint forming process includes providing a single row of lugs on one side of the joint to be formed, and providing a respective double row of lugs on the other side of the joint to be formed. A gap between opposing lugs of the double row varies along the row. The wing side and the fuselage side of the wing box structure are brought together such that the lugs of the single row are located within the respective gaps between opposing lugs of the double row, and the lugs are pinned to form the series of pinned lug joints. Also, a joint formed by the method.

Abstract: Sets of power amplifier branches (which comprise an RF/microwave amplifier stage) are power combined within each stage and each set of power amplifier branches are biased in different classes of operation by bias circuits possessing different impedance characteristics such that the fundamental frequency components present at the output are in-phase with one another and the IMD3 components are anti-phase over a broad range of power levels. The RF input signal is provided by the output of the previous stage of the RF/microwave amplifier. The output of each stage is formed by power combining sets of these power amplifier branches, each of which are separately biased, so the fundamental components are additive resulting in the maximum possible output power and the IM3 components cancel partially or completely.

Abstract: The present invention provides a reliable communication protocol that provides multicasting of digital messages on an interprocessor link coupling together a plurality of processors of a load control system. Preferably, the load control system includes a plurality of sub-systems, with a number of the processors in each sub-system. The processors are each characterized by a unique individual address, while all of the processors of a single sub-system are characterized by an identical multicast address. The processors re-transmit digital messages on the communication link if a target address of the digital message is equal to the multicast address. The processors determine if acknowledgement messages are received from each of the processors from which acknowledgement messages were expected during a predetermined amount of time after transmitting an initial digital message, and transmit a retry message in response to determining that the acknowledgement messages were not received.

Abstract: A system and method for network pairing with two or more wireless communication devices, in which each device includes a wireless transceiver. For each device, the wireless transceiver has indirect communication with the other communication device via a first ad hoc connection to an intermediate communication device, and is capable of direct communication with the other communication device via a second ad hoc connection. The wireless transceivers of the wireless communication devices exchange network address information needed for paired communication between the devices, thus minimizing the need to search and discovery for paired communication.
