A node connector in a double layer grid-type of space frame preferably is an extrusion which includes an open-ended tubular portion for snugly at least substantially encircling a frame chord member of desired cross-sectional configuration which is disposable in the passage. The node connector has fixed external elements which extend along the connector parallel to the passage. Those elements define facing parallel flat surfaces arranged in at least two pairs of such surfaces. The surfaces of each pair lie equidistantly from a center plane between them. Each center plane is parallel to the passage axis and preferably includes the passage axis. Each pair of facing flat surfaces of the node connector can cooperate closely with opposite flat surfaces at the end of each of other frames framing member placed between the facing surfaces. The node connector can be secured to a chord member in its passage and to ends of other framing members by shear pins which have zero clearances in node connector holes and in holes or passages through the respective framing members. The space frame can be a movable armature for a curved solar reflector, the space frame having a V-shaped major surface. At least some of the framing members can be thin wall tubes modified to have opposing, flat-exterior wall zones along the length of each tube and in which the wall thickness is locally increased and through which shear pin holes are defined.

The present invention provides a transmission device for predistorting a digital signal in order to compensate distortion, then amplifying and transmitting it. A digital input signal is converted to a first analog signal by a first D / A converter. Separately, the digital input signal is also subjected to predistortion. A compensating signal is then generated from the digital input signal and the predistorted signal. The compensating signal generated thereby is converted into a second analog signal by a second D / A converter. The first analog signal and second analog signal are then added, this addition operation giving a compensated analog transmission signal. This analog transmission signal is supplied to the amplifier for amplification, and then transmitted via an antenna.

A tubular structural member has substantially constant cross-sectional size and configuration along its length between its opposite ends. The member has a pair of parallel oppositely aligned flat areas in its exterior surface. The member has substantially uniform wall thickness except in a selected portion of each the opposing areas where the member's wall thickness is a selected amount greater than the uniform wall thickness. The increase wall thickness preferably is manifested in the interior of the tubular member. The cross-sectional area of the member can have orthogonal neutral axes, and the exterior dimension of the member along one of those axes can be greater than the exterior dimension of the member along the other of those axes which is normal to the exterior flat areas; the amount and distribution of the thickening of the member's walls over the uniform thickness can be defined to cause the section modular of the member about each of the neutral axes to be substantially equal.

A method for holding a sintering filler material during a brazing / sintering operation for repairing a damaged area of a component wherein the component is in either a bonding face down position, bonding face vertical position or bonding face up position. The method includes providing a wire mesh and attaching the wire mesh to the component in a location corresponding to the damaged area. Further, the method includes forming a gap between the wire mesh and the component. Moreover, the sintering filler material may be inside the wire mesh or both inside and outside the wire mesh in order to secure the sintering filler material to the damaged area.

This invention pertains to the connection between a radio frequency circuit and its antenna. Miniaturization of radio frequency integrated circuits has made attaching these circuits to their antennas increasingly difficult and costly. This invention uses magnetic coupling, as performed in transformers, between circuits and antennas as a practical solution to reduce cost and effort in attaching the two sides as well as to protect the circuit against electrostatic discharge. Furthermore a simple pre-assembly testing methodology is accounted for as an additional benefit of the method.

The invention relates to a radiation detector (3) comprising a detector array (5) having a periodical pattern of detector elements (51). Each detector element (51) comprises a sensor element (53) for converting incident radiation into an electrical charge. The sensor elements (53) are spaced at a sensor-center-to-center distance. Over the detector array (5) an imaging radiation-collimating structure (7) is disposed. The imaging radiation-collimating structure has a periodical pattern of radiation absorbing elements, which radiation absorbing elements are being spaced at a collimator center-to-center distance. The radiation detector (3) comprises a combiner for generating combiner-signals from the electrical charges of the sensor elements (53) of groups of an even number of sensor elements adjacent in a direction of the periodicity of the pattern of the radiation absorbing elements. The collimator center-to-center distance is approximately equal to twice the center-to-center distance of the groups of adjacent sensor elements. The radiation detector (3) further comprises a low-pass filter for receiving the combiner-signals and suppressing components of the combiner-signals with a frequency equal to or higher than a collimator frequency corresponding to the collimator center-to-center distance, thus providing a radiation detector which is easier to manufacture than the known radiation detector and which requires a relatively low degree of precision for the positioning of the radiation absorbing elements of the imaging radiation-collimating structure without introducing visible Moire effects in the image of an object to be imaged by the detector.
