Abstract: A method for forming, in a single step, a silicone manifold interconnecting a plurality of silicone tubes is performed by providing a silicone insert piece having a network of interior channels dimensioned the same as the silicone tube interiors. Solid non-silicone plugs are inserted into the insert piece and the ends of the silicone tubes and the resulting assembly is placed in a mold cavity. Liquid silicone is added to the mold cavity and is then heated and cured to form the desired manifold interconnecting the tubes. The manifold is then removed from the mold and a source of pressurized air is used to blow out the plugs.

Abstract: A space diversity antenna system provided with dither circuitry in the signal path to one of the antennas to switch a circuit element in and out of the signal path at a high rate. The circuit element can be an amplitude attenuator or a phase changer. This switching results in the substantial elimination of nulling between the two antennas.

Abstract: A microstrip antenna radiates and receives six beams in sequence out of a common aperture and processes return signals with common electronics in order to measure the velocity components relating to a backscattering surface. Sequentially, the first four beams are processed by measuring Doppler shift in a return signal while the last two beams are processed for time correlation. The result of the present invention is a combined time correlation and Doppler measurement velocity sensor available for operation over virtually all terrains and the vehicle speed range.

Abstract: A bidirectional multispeed indexing control system for a display unit which has an increment input and a decrement input so as to be controllable to sequentially index through an ordered list of discrete elements. The control system has a two-button user interface. The user presses one button to increment once, and holds that button to continuously index at a slow fixed speed. To increase the indexing speed, the user presses the second button while continuing to hold the first button. Indexing speed will continue to increase until either a maximum speed is reached or the user releases the second button, at which point the indexing speed decreases from the value reached while holding the second button. To stop indexing, both buttons are released. To increment in the opposite direction (i.e., decrement), the order in which the buttons are pressed is reversed.

Abstract: A method for forming a fitting at an end of a braid-reinforced silicone tube. A short length of the outer layer surrounding the braiding is removed and the exposed braiding is folded back over a first silicone ring and then a second silicone ring is placed over the folded-over braiding. The end of the tube is then placed in a mold which is then filled with liquid silicone. After the silicone is heated and cured, a unitary structure of tube and fitting results. Since the braiding is part of the unitary structure, it cannot be pulled out, thereby increasing the reliability of tube and fitting.

Abstract: An electromagnetic shield assembly for an optical fiber connector which comprises a conductive frame member enclosing an open space and a plurality of conductive fibers each secured at only one end to the frame member and extending into the open space. The free ends of the conductive fibers overlap in a central region of the open space to provide a “self-healing” mesh shield.
