Patent EP-0464418-A2 (EP)
Inventor: MOSER HARDY
IPC: G09G3/32
Filed: 1991-06-13
Abstract: For display elements disposed in the form of a matrix on manual switching sets or switching positions of communication switching systems, a circuit arrangement is to be proposed with which control and storage expenditure can be held within acceptable limits even where larger numbers of display elements are involved. The display panels are to be capable of extension in blocks without incurring additional control expenditure, where only additional memories need to be disposed. A display module is provided which is controlled from the switching set or switching position but which operates automatically and contains a receiving register, a status memory, a column memory and a control device. The status memory is activated cyclically, whereby the contents of each line are loaded temporarily into the column memory. The diode lines and the diode columns of an LED matrix are fed coincidentally with current so that the desired display elements are illuminated. Only when changes in the display status occur are instructions received in the receiving register, which pass via the control device to a conversion device. When an activation instruction for a display element is received there, the individual address of the latter is combined with the status read out from the status memory. When a de-activation instruction is received, the inverted individual address of the display element concerned is combined with the preceding status. The respective new status is transferred to the status memory. This circuit arrangement is designed as an automatically operating display device for switching sets or switching positions, and information needs to be transmitted only when a change occurs in the status of the display elements. The control and memory expenditure is relatively low even when a larger number of display elements is involved, and only additional memories are required if the system is extended. <IMAGE>

Abstract: A document (11) to be scanned is corner referenced on a transparent platen (12), with the document's image facing down. The platen defines an X-Y coordinate system matrix. A moving line of light (24) extends in the X direction and illuminates the document's image, line by line, as the line of light moves in the Y direction. The line of light that is thus reflected from the document is sensed by a linear CCD sensor array (27) having a large number of individual sensor cells (28) arranged in a line that effectively extends in the X direction. Each cell of the CCD array defines an individual pixel (PEL) within the line of light that is reflected from the document. A reflection target (54) is located at a known position relative to the platen's referencing corner, to be scanned prior to scanning the document. Sensing of the target enables (1) the X direction physical position of the CCD sensor array relative to the referencing corner to be accurately determined (86), and (2) the Y direction physical position of the line of light relative to the the referencing corner to be accurately determined (87), both parameters being determined prior to scanning of the document.

Abstract: In a video signal processing apparatus suitable for use with a VCR of the VHS PAL system or NTSC 8 mm system, an output signal of a voltage-controlled oscillator (VCO) (31) is frequency-divided to generate a four-phase signal including four kinds of signals having a phase different by 90° from each other. The VCO has a free-running frequency substantially equal to or integer multiple of, a sum of a television color subcarrier frequency f SC  and a horizontal synchronizing frequency f H  multiplied by 40.125 or 47.25. Eight or four kinds of signals having the color subcarrier frequency f SC  and a phase different by π/4 or π/2 from each other are generated using a crystal oscillator (30) and phase shifter (39). The eight or four kinds of signals are selected by a selector (40) in a predetermined order at each one period of the horizontal synchronizing signal f H , the sequentially selected eight or four kinds of signals each having a phase shifted by π/4 or π/2 from the previously selected relevant one. The selected signal and the corresponding four-phase signal are inputted to a delayed flip-flop (D-FF) (35) which in turn generates a difference or subtraction result between the two inputted signals. This subtraction signal is frequency-divided to the horizontal synchronizing frequency f H . The phase of the obtained frequency-divided signal is compared with the phase of the horizontal synchronizing frequency f H  by a phase comparator (37). Using the phase difference therebetween, a control signal for controlling the VCO is generated. An output of the VCO is frequency-divided to generate the carrier frequency used for frequency conversion without generating unnecessary harmonics.

Abstract: A graphic data processing unit (11) which, when graphic information is input for individual graphical forms obtains three-dimensional spatial position information (region information) spheres containing the graphical forms, and transfers the same together with the graphic information to a graphic data base (12) to be stored therein. Further, the processing unit obtains three-dimensional spatial position information of a grouping sphere containing several graphical forms, and registers the same as grouped region information in a region administration table (13). Upon designation of a display region, the processing unit (11) discriminates whether the grouping sphere lies within the designated region with reference to the grouped region information. If the grouping sphere lies outside the designated region, all the graphic elements constituting the group are excluded from those to be displayed. If the grouping sphere lies within the designated region, a graphic data retrieval/display unit (14) discriminates whether the sphere lies within the designated region for each graphical forms with reference to the region information. If the sphere lies outside the designated region, the graphical form is excluded from those to be displayed. If the sphere lies within the designated region partially or entirely, the graphical form is selected as the one to be displayed, and is displayed on a display device (15). Accordingly, the graphical form contained entirely or partially within the designated three-dimensional space can be retrieved or displayed at high speed, thereby improving working efficiency.
