Abstract: A method of manufacturing an aircraft component such as a wing rib. The method comprises: providing a body with two or more connectors arranged in a line on the body, each connector having an arm extending from the body, a first flange positioned on a first side of the line, and a second flange positioned on a second side of the line; and attaching a separate connector to the body, the separate connector having an arm extending from the body, a first flange positioned on a first side of the line and a second flange positioned on a second side of the line.

Abstract: This invention relates to an optical device and system for producing a holographic optical element or digital hologram. Various techniques of producing digital holograms have been proposed. However, they tend to suffer from long exposure times, as well as problems associated with control of two or more independent beams of coherent light used to produce a hologram. Problems become even more acute as pixel size decreases. The present invention provides an optical device including: a beam deflector, adapted to deflect a collimated beam of coherent light to produce an incident beam; a beam splitter for producing first and second beams, said beams being displaced so that the angle of deflection of the first beam is the same but opposite to the angle of deflection of the second beam; and a combiner combines the first and second beams so as to produce an interference pattern at an output plane.

Abstract: A mobile telephone system has a base transceiver station (BTS) that provides radio communication with a mobile handset (MS) and also communicates with a control station (BSC) through a communication link in the form of a leased line which provides a first communication path with a predetermined bandwidth for signals communicated between the BTS and the BSC. A communication network in the form of an ISDN is used to provide a selectively connectable second communication path between the BTS and the BSC so as to augment the bandwidth available for the signals during periods of peak demand. In order to accommodate different call connection times in the system through the leased line and the ISDN, the BSC/BTS are arranged to produce all connection signals that initiate billing at the same time irrespective of the path used to make the call connection.
