Filed: 1989-10-27
Abstract: A procedure for replacing an existing switch (62) with a greater-capacity replacement switch (12) in a communication system (10) is disclosed. The replacement switch (12) has redundant interconnect memories that can store different interconnect maps. The replacement switch (12) also has logic circuitry that forces the replacement switch (12) to operate using only a selected one of the redundant interconnect memories. The procedure loads a transparent map into the interconnect memories. Next, the procedure couples the replacement switch (12) in series between drop facilities (14) and the existing switch (62) and between the existing switch (62) and line facilities (16). The coupling scheme and transparent map route communication through both the replacement switch (12) and the existing switch (62) without substantially affecting service. Next, a master interconnection definition similar to an interconnection definition within the existing switch (62) is loaded into one of the redundant interconnect memories of the replacement switch (12). Operation of the replacement (12) is switched to utilize this master interconnection definition without affecting service.

Abstract: A resistive fault in an electrical cable is located by applying a DC voltage to one end of the faulted cable conductor. The steady state DC voltage and current are measured at the end of the conductor where the voltage is applied. Simultaneously, the DC voltage is measured at the other end of the cable. The voltage is then reversed in polarity and the measurements repeated. Several repetitions of this procedure at each end of the conductor yields sufficient information to compute the location of the fault with reasonable accuracy. The procedure is carried out using two computer-based units, one at each end of the cable, with the two units communicating over the conductor under test.

Abstract: A multiple image, single display system (2) includes a monochromatic display source (4) which provides first and second rapidly alternating visual images (8, 10) which pass through an active polarizer assembly (14). The polarizer assembly includes an image polarizer (20), which polarizes all the light to a left hand circular polarization, and a polarization changer (22) coupled to the display source by a synchronizer (28). The polarization changer switches the polarization of the first image but not the second image. A first user (34) sees the first image, but not the second image, through a right hand circular user polarizer (16) while a second user (36) sees the second image, but not the first image, through a left hand circular user polarizer (18). The user polarizers are wave-length sensitive so they block light only if the light has the same polarization and if the light is the wavelength of the light produced by the display source; the user polarizers are otherwise transparent to visible light. This permits the invention to be used in critical low light situations.

IPC: D04B21/06
Filed: 1990-08-21
Abstract: To manufacture single-face warp knits having differently coloured areas it was hitherto customary to knit a number of courses with threads having two different colours. The threads whose colour was visible were tricot-stitched, while the threads whose colour was not visible were pillar-stitched. For this number of courses it was therefore the case that only two differently coloured areas could appear. 
<??>To increase the number of differently coloured areas for a number of courses, at least three threads (1, 2, 3) in different colours are used. The threads whose colour is visible are plain- or twill-stitched over at least two courses at a time, and the threads whose colour is not visible are pillar-stitched, adjacent pillar stitches consisting of differently coloured threads.

Abstract: An improved method and apparatus are disclosed for processing spectral data to remove undesired variations in such data and to remove interfering information present in the data. The method and apparatus corrects multiplicative effects present in the spectral data. Additive and interferent contributions can be corrected as well. In one aspect of the method, coefficients for a selected appropriate model are applied to the input spectral data based on first and second reference spectra. The spectral data are then corrected based on the estimated coefficients at least as to multiplicative errors for producing a linear additive structure for use in calibration, validation and determination by linear multivariate analysis. The method and apparatus will improve the accuracy of spectral data structures derived from measurements using spectroscopy, chromatography, thermal analysis, mechanical vibration and acoustic analysis, rheology, electrophoresis, image analysis and other analytical technologies producing data of similar multivariate nature.

Abstract: In a semiconductor integrated circuit wherein a bipolar transistor and an insulated gate type comple­mentary transistor are formed on a single semiconductor chip, the insulated gate type complementary transistor is formed in an island-shaped epitaxial layer (4) which is completely isolated from a semiconductor substrate (1) and the other part of the circuit and which has a conductivity type (N) opposite to that (P) of the semi­conductor substrate, and an electrode (176) is formed in contact with a region (62) for isolating the island­shaped epitaxial layer from the other part of the circuit. In the semiconductor integrated circuit, since the CMOS circuit is formed in the island-shaped epitaxial layer isolated completely from the semicon­ductor substrate and the other part of the circuit, noise occurring in the CMOS circuit does not adversely affect the bipolar circuit. Thus, the operation margin of the semiconductor integrated circuit is increased, and the malfunction of the circuit can be prevented.

Abstract: An infrared detector element (20) comprises a flexible continuous film (10) of polymer material which has pyroelectric or other temperature-dependent characteristics and which is also piezoelectric so also generating microphony when it vibrates. In accordance with the invention the mounting arrangement (30,31,32) for the film (10) comprises mutually-spaced supports (32), e.g. tapered ridges (32) of a moulded-plastics substrate (30); the spacing (x) between neighbouring supports (32) adjacent to the detector element (20) is sufficiently small and the tension (P) of the film (10) is sufficiently large that the natural frequency of vibration of the parts of the polymer film (10) between these neighbouring supports (32) is higher than the frequency bandwidth of the detector, e.g. as determined by the highest operating frequency of a read-out circuit to which the detector element (20) is connected. This arrangement significantly reduces the effects of microphony in contributing to the electrical output of the detector. The ridge portions (32) may form a continuous network around cavities (35) below the detector elements (20), and a conduit may extend into each cavity (35) to equalize the ambient pressure inside each cavity (35) with that at the opposite face (12) of the polymer film (10).
