Abstract: An optimal image-quality selection apparatus includes a quantizer (2) to quantize the image from a scanner. The quantizer outputs video signals (b1, b2) representing the image at different depth levels. Graphic blocks are extracted by extractors (3, 4) and counters (5 - 8) count for each video signal the total number of graphic blocks (e1 and e2) and the number (f1 and f2) of graphics blocks having a predetermined size. Dividers (9, 10) calculate the ratio (f1/e1 and f2/e2 respectively) of the number of graphic blocks having a predetermined size to the number of all graphic blocks of the image for each of the depth levels of colour, and a comparator (11) selects the image having the largest of the ratios as an image of optimal quality.

Abstract: In a radar apparatus, an RF signal is transmitted at a frequency modulated by a sawtooth signal. The transmitted RF signal is mixed with the transmitted signal reflected from an object. The resulting IF signal is analyzed into a Fourier series having a DC coefficient and harmonic frequency coefficients. The range to the object is determined from the harmonic frequency coefficients in multiples of the range resolution determined by the RF bandwidth of the apparatus when the DC coefficient is less than-each of the harmonic frequency coefficients. The range to the object is determined to be within 1/2 the range resolution determined by the RF bandwidth when the DC coefficient is greater than each of the harmonic frequency coefficients.

Abstract: A resin composition for sealing semiconductors which comprises (a) a modified epoxy resin composed of (i) a graft polymer of an epoxy resin having the structure (I);
      and a vinyl polymer and (ii) a soft vinyl-modified silicone polymer as particles having an average particle size of not more than 1.0 micron, which are uniformly dispersed in the graft polymer, (b) a hardening agent and (c) an inorganic filler, is herein provided. The resin composition for sealing semiconductors exhibits a low thermal expansion coefficient and a low elastic modulus, generates low stress when thermal shock is applied thereto and exhibits high heat resistance during soldering even after moisture absorption. Therefore, if the composition is used to seal large-scale semiconductor devices having high degree of integration or small-sized, thin semiconductors such as flat packages, these semiconduc­tors provide high reliability.

Abstract: A dual digital signal processor (DSP) provides real time links between multiple time division channels of a digital carrier system (e.g. T-1) and a host data processor. Operating only on digital signals, internally and at its interfaces to the carrier and host systems, the DSP exchanges data and control signalling information with the carrier system and data and control information with the host processor, converting the data in passage to different digital forms. At the interface to the carrier system, signals are received and transmitted in a form adapted to diverse terminal equipment of users remotely linked to the carrier system via the switched public network. At the host interface, signals are transferred and received in a form suited to the data process requirements of the host system (e.g. data bytes directly representing alphanumeric characters). Thus, the DSP acts as the equivalent of multiple different types of modems in performing required conversions. The DSP may also perform processing services in order to reduce the processing burden on the host system (e.g. parity checking of data, detection of specific character functions in data or specific tones in audio signals, selective routing of voice to host storage for voice mail applications, etc.)

Abstract: An antenna arrangement for receiving television signals from a satellite comprises a parabolic (5) which collects the signals and feeds them through a feedhorn (6), then through a polarisation switch (8) and a low noise block to the receiver. The polarisation switch (8) comprises a ferrite rod (16) supported in a dielectric holder (18) within a circular waveguide (14). The ferrite rod (16) is surrounded by a solenoid coil (19) which is energisable to rotate the plane of polarisation of the signals passed along the waveguide, so as to enable the switch to select either horizonally or vertically polarised signals. The current in the coil (19) is switchable between two values, one having a predetermined magnitude in one direction through the coil and the other having the same predetermined magnitude but in the opposite direction through the coil. The current levels are selected such that the corresponding angular positions for the plane of polarisation are +45° relative to the datum position for the Polarisation plane and -45° with reference to this datum position. The dielectric holder  (18) has a stepped configuration so as to match the loaded waveguide to the empty waveguide.

Abstract: Die Erfindung beschreibt ein Schaltkennfeld für ein Automatikgetriebe in einem Kraftfahrzeug, sowie ein Verfahren zum Ermitteln eines Schaltsignals aus diesem Schaltkennfeld. Durch das Verfahren soll verhindert werden, daß das Getriebe im Schubbetrieb und gegebenenfalls unter hoher Querbeschleunigung hochschaltet. Erreicht wird dies, indem das Überschreiten der Hochschaltkennlinien durch den Betriebspunkt festgehalten wird. In einer bevorzugten Ausführung wird dabei die Stellung des Fahrpedals gemessen und beim Überschreiten der Hochschaltkennlinie in eine Fahrpedalgeschwindigkeit umgewandelt. Der so erhaltene Wert der Fahrpedalgeschwindigkeit ist ein Maß dafür, ob das Getriebe hochschaltet oder im bisherigen Gang verbleibt. Gegebenenfalls wird beim Überschreiten eines Querbeschleunigungsgrenzwertes der Hochschaltvorgang unterdrückt. <IMAGE>

Abstract: A sleep timer function for consumer electronics equipment automatically turns off the equipment after a predetermined time interval. During the final two minutes of the sleep time interval, the sleep timer circuitry (113, 132, 134) gradually decreases the volume or provides a visual indication that automatic turn off is imminent. The reception of any modulated infrared (IR) signal, transmitted from any source (128), during the timer period is interpreted by the sleep timer function controller as an indication that the user is still awake. In response, the controller resets the count of the sleep timer (113) to the maximum period, thus deferring the automatic turn off of the equipment.

Abstract: A pre-programmable multiple pause points system for a post-collation copying system for a copier (10) with associated sorter bins and a recirculating document handler (RDH) (20) in which a set of document sheets may be loaded, recirculated, and copied for making a plural number of identical consecutive copies per document per circulation and outputting them to selected sorter bins for collation. This system is particularly adapted for a system of "limitless sorting" in which the plural identical copies are job subsets collated in a variable limited number of sorter bins, normally substantially less than the total number of bins, and wherein the total job is completed with further RDH document circulations and further job subsets productions. The pre-programmable pause points system provides for the automatic variable number of pauses or job interrupts and for their occurrence at those points in the copying cycle appropriate for inserting job inserts or other special copy sheets into the bins being filled, repeatably, at any selected document copying point.
