Abstract: The invention relates to a display device having a multiplicity of display points, in which each display point is formed by the front-side end of an illuminable optical fibre. The number of the display points for a large-area display that is viewed from a great distance can be substantially reduced by arranging to fix in a display panel in front of each end of an optical fibre a light collector which has a round and larger cross-section than the cross-section of the optical fibre, forms a section convexly curved with a prescribed radius where it faces the end of the optical fibre, and is provided where it is averted from the end of the optical fibre with a rotating phase which is at a prescribed angle to the central axis of the display point, and by arranging that the light collector projects on the display panel with the section formed by the phase, and that the front side of the light collector averted from the end of the optical fibre is roughened.

Abstract: A non-reversing load detector for a reciprocating element comprising a pair of matched strain gauges (12, 14) bonded to a piston rod, one gauge being fixed parallel with the axis of reciprocation and one fixed transverse thereto. The former gauge (12) is the active one and the other (14) is a dummy. Circuitry is coupled to the gauges to sense the disparity in resistances thereof, and further transistor circuitry is provided to establish compressive and tensile thresholds of the piston rod. If given thresholds are not reached, or manifest non-sinusoidal excursions, detector circuitry signals a non-reversing load condition.

Abstract: A precision satellite tracking system (10) incorporating a novel smoothing processor (14). The satellite tracking system (10) estimates an angle between an antenna (11) boresight and a desired line of sight to a moving satellite (12). The smoothing processor (14) receives a sequence of pointing error measurements and using a Taylor series mathematical model of the satellite motion, the processor (14) utilizes the sequence of measurements to generate the coefficients of the Taylor series model. The processor (14) then executes a sequential, discounted least mean square algorithm to estimate the satellite's angular position, velocity, and acceleration as a function of time. Based on these estimates, the processor (14) determines incremental adjustments to azimuth and elevation pointing angles of the antenna (11) to maintain the center of an antenna beam (13) on the moving satellite (12). The information is used in a program track mode to continually update the pointing of the antenna beam (13) during the measurement process. The satellite tracking system (10) provides continuous tracking of the antenna (11), which minimizes the instantaneous error between the reported direction of the line of sight and the actual direction to the satellite (12).

Abstract: An integrated driver circuit package for a liquid crystal display or the like (1) comprises an integrated driver circuit having outputs for driving a display section (2) of the liquid crystal display (1). Coplanar connection electrodes (5) extend outwardly from an edge of the package for connecting the outputs to the display section (2). The connection electrodes (5) are spaced apart in such a manner that adjacent connection electrodes (5) located towards the centre of the edge of the package are closer together than adjacent connection electrodes (5) located towards an end of the edge. The spacing between adjacent electrodes (5) thus progressively increases from the centre of the edge to the ends of the edge.

Abstract: The invention relates to a process for producing mouldings, in particular also geometrically complex mouldings, using powder metallurgical processes. To this end, the powder material is fed into a single-use, dimensionally stiff plastic, preferably expanded polystyrene, compression mould, compacted cold-isostatically to form compacts and subsequently sintered. The process according to the invention combines the advantages of axial pressing in a female mould, that is to say the production of dimensionally stable, geometrically complex mouldings in an economical manner, with the advantages of cold-isostatic pressing of a conventional type, that is to say high and uniform compaction of the powder to form corresponding non-symmetrical mouldings of high mechanical strength.

Abstract: A bidirectionally movable carriage (12) in an ink-jet printer contains either a color or a black ink cartridge (14). When a color cartridge is mounted on the carriage, a rotatable service station (10) having both color (18) and black cartridge (20) service stations mounted thereon rotates to position the color service station adjacent the travel path of the color cartridge. A cap (66) on the color service station includes a lip (82) for sealing against the color cartridge and a flexible diaphragm (94) which flexes to minimize pressure differentials between the interior and exterior of the cap. Because ink vapor diffusion through the diaphragm is possible, a diffusion vent (102) is provided to a chamber (95) on the side of the diaphragm exposed to the exterior of the cap. The diffusion vent permits diaphragm flexing while inhibiting ink vapor diffusion from the cap.

The level of the reference signals can be controlled according to the duration of the exposure time such that a difference between the first and second reference levels increases as the exposure time become shorter. A further embodiment uses first to fourth comparators and first to fourth reference levels to improve the response speed of the exposure control. To avoid deterioration of the image signal the comparator circuit can be disabled during the active image intervals.
