Abstract: Faulty subarray module circuit boards are detected in a phased array antenna (68) having many subarray module circuit boards while the antenna (68) is fully assembled and operationally integrated with a radar (70) system. A far field radio frequency test source (73) illuminates the antenna (68). Binary digital signals that control subarray steering bits are set to a reference setting. A particular subarray module circuit board that is under test has its 180° main phase bit toggled between 0° and 180°. The radar (70) selects the output of that particular subarray module by Doppler filter type of software filtering. The amplitude of the in-phase and quadrature phase (71, 72) signals from the radar (70) is recorded. The binary digital signals that control subarray steering bits are set to a second setting. The 180° main phase bit of the module under test is again toggled between 0° and 180°. The output of the module under test is again selected by Doppler filter type of software filtering. The amplitude of the in-phase and quadrature phase signals from the radar (70) is recorded. The phase difference from the reference setting to the second setting is computed and compared with a predetermined threshold. If desired, the test source (69) may have a multi-element feed including multiple dipoles, each dipole having a radiation pattern wide enough to cover two rows of subarray modules, the test source (69) being switched to the particular one of the dipoles that illuminates the row including the module under test.

Abstract: An electroluminescent structure and method of fabrication of that structure in materials which have an indirect bandgap in their bulk form. The processing steps can all be standard VLSI methods. Quantum columns, quantum wires or quantum dots may be formed, for example in an array, by masking, reactive ion etching and oxidation. Columns (20) may be formed by etching techniques and consist, for example, of p-type silicon material (14) which forms a p-n junction with an n-type silicon end portion (16). The space between the columns is filled with oxide (22) formed by oxidising the silicon columns during a column narrowing process. When the semiconductor core is sufficiently thin, quantum mechanical confinement effects raise the energy and the radiative recombination efficiency of injected carriers. Tuning the core diameters allows selection of individual or multiple wavelength emission bands.

Abstract: In order to achieve cost reduction and improve the reliability of an IC integrating power element, together with a control circuit and protective circuit, power elements are controlled by a low potential circuit (L) depending on a low potential power source (VL), a high potential circuit (H) depending on a high potential power source (VH), and a medium potential circuit (M) depending on an output-stage voltage. As a result, the required number of high-withstand voltage elements is reduced, hence the size of a p-channel MOSFET (22) can be reduced, enabling a reduction in chip size and cost, and making it possible to obtain a constant main power source potential and voltage between the parts of the high potential circuit (H).

Abstract: A method for making an optical layer (202, 206, 301) including, a first pattern projected onto a radiation sensitive surface (103) having a first charge. Radiant energy is used to locally change the surface charge, thereby producing local areas having a second charge. The surface is exposed to an optical media having a charge that attracts the optical media to the surface. A substrate (123) with an associated charge is passed in proximity to the surface having the optical media attached. The optical media detaches from the surface and is deposited onto the substrate (123). The substrate (124) is heated, thereby fusing the optical media to make an optical layer (202).
