Patent EP-0367418-A2 (EP)
Inventor: GONZALEZ-LOPEZ JORGE
IPC: H04N1/393
Filed: 1989-10-06
Abstract: An image interpolator implements an interpolation function providing real time, continuous zoom capability to an image display system. Output image pixels are obtained by interpolating the values of the colour or intensity of the 2x2 matrix of pixels surrounding the point on the input image. The disclosed arrangement employs a bi-linear interpolation algorithm implemented in the form of cascaded one-dimensional interpolation circuits. Magnification control is established so that a unit increment of the zoom controller, such as a cursor on a tablet, results in a constant increase in the degree of magnification. The coefficients required for the interpolation are generated in real time avoiding the need for time consuming table look-ups.

Abstract: A bipolar transistor (200) exhibits improved function due to its emitter structure. A single layer of conductive material (240) forms both the emitter contact (210) and the base contact (236) in the transistor (200) structure, which structure has particularly shallow emitter and base junctions (about 0.15 micrometer or less). The self-aligned emitter contact (210), isolated from the base contact (236) by a dielectric-filled trench (234), permits overall size reduction of the device, whereby junction area and accompanying leakage across junctions is reduced. In addition, when the structure of the bipolar transistor (200) is such that the dielectric-filled trench (234) isolates the emitter (212) area from both the base contact (236) and the extrinsic base (224), it is possible to provide improved base conductivity without generating peripheral transistor effects. The bipolar transistor (200) can be either N-P-N type or P-N-P type depending on the materials of fabrication, although high speed devices are typically of the N-P-N type.

Abstract: The invention relates to a sensor for the measurement of magnetic flux which consists of a superconducting ring incorporating a Josephson element. The ring is coupled to an electrical oscillatory circuit, referred to as a tank circuit. The object of the invention is to provide a sensor which can be operated at higher frequencies than the hitherto known sensors of this type with at least equally good coupling between tank circuit and superconducting ring. For this purpose, in the sensor according to the invention, the electrical oscillatory circuit is formed from a piece of stripline which forms a resonator for standing electrical waves. Located in said stripline is an opening with adjacent Josephson element for the magnetic flux to be measured. The superconducting ring is consequently built into the strip resonator, or superconducting ring and tank circuit are one component. The Josephson element is arranged along the central or longitudinal axis of the strip resonator. To capacitatively couple the strip resonator to an evaluating electronic system, a further piece of stripline is provided adjacent to the strip resonator. In a special design of the sensor, two openings are provided in the strip resonator. <IMAGE>

Abstract: 2.1 The aim is that, when broadband communication networks are introduced, existing switching systems and terminals of the integrated-services digital network ISDN can be retained unchanged and cooperate with broadband communication switching systems operating on an asynchronous basis. 2.2 One access member in each case of an ATM switching system operating in asynchronous time-division multiplex is connected to an associated access member in an ISDN switching system. At this point, ISDN narrowband data are added to the broadband data and/or separated from these by operating with violations of the coding rule. Both types of data are jointly transmitted via a subscriber line to a network terminating device to which terminals of various categories can be connected. 2.3 Both broadband switching systems according to the asynchronous time-division multiplex method and existing ISDN switching systems can interwork without requiring large-scale preliminary work. On the introduction of broadband communication networks, existing network structures of the integrated-services digital network can be retained and existing terminals can also be used which can easily communicate with terminals of the broadband communication network. <IMAGE>

Abstract: In order to simulate sounds of an acoustic musical instrument such as a bowed stringed instrument, an electronic musical instrument employs a musical tone control apparatus which at least contains an operating device (34, 34A) and a detecting circuit (22). Herein, when operating the operating device which can be operated in a two-dimensional area, the detecting circuit detects operation information corresponding to an operating position or an operating displacement of the operating device. Then, velocity information is generated based on the operation information. Thereafter, a musical tone is generated in response to a musical characteristic corresponding to the velocity information under a condition where the operating device is now operating. Preferably, the operating device is configured by a digitizer (34) on which surface an electronic pen (34A) is moved two-dimensionally by the performer. Thus, it is possible to impart the varied performance expression to the musical tone to be generated.

Abstract: An input/output device (72) has a processor (202) which processes data strings received by the device (72). When a data string is received, it is passed to a serial interface (207) and a timing means (208). The serial interface (207) generates a signal which interrupts the existing processing by the processor (202) and causes the processor to start processing of the newly received data string. At the same time the timing means measures (208) the length of the data string and compares it with a predetermined length set by user-controllable data setting means (210). If the data string length reaches the predetermined length, the processor (202) is triggered to stop processing the new data string and to recommence the processing it was performing prior to interruption. The unprocessed part of the new data string is stored in a memory (205). 
     In this way, urgent data strings, which are generally short, are processed rapidly and longer data strings are processed after the urgent data strings. It is not necessary for the data string to contain any information to identify its length.

Abstract: A computer system includes a plurality of central processing units (CPUs) each of which has a direct mapped cache memory. The system also includes a main memory, and one or more display frame buffers. The cache normally operates in a write back mode, whereby updated data is written back to main memory only when a cache block is reallocated to store a new block of data. A tag for each block of data stored in the cache includes a Shared flag which indicates whether the corresponding block of data may be stored in the cache of another CPU. When a block of data stored is modified, it is immediately written to main memory if the tag for that block has an enabled Shared flag. To make the cache operate in a write-through mode for blocks of image data, the system stores an enabled Shared flag in the cache whenever a block of frame buffer data is stored in the cache. A circuit in the cache detects when the CPU is writing an entire block of image data to an address in the frame buffer and causes the cache to write the block of image data directly to the frame buffer without storing the image data in the cache. An address circuit in the cache stores image data from the frame buffer only in a predefined fraction of the cache, and thereby restricts the amount of other data stored in the cache which may be displaced by image data.

Abstract: A rotatably driven mandrel (2) is mounted on a pivot arm (1). A smoothing roller (3) is provided on a further pivot arm (4), and is biassed into contact with the package to apply a force to the package periphery, and hence control the packing density of the wound thread. During winding, as the diameter and weight of the package (9) grows, the increase in diameter deflects the roller (3) downwardly. A sensor (12) detects this and, via a mechanical linkage (11), causes the motor (10) to raise the pivot arm (1) by an amount that maintains the position of the roller (3) substantially constant and maintains the force supplied by the roller (3) to the package periphery substantially constant. This allows the packing density to be kept substantially constant, independently of variations in the weight of the package (9).

Abstract: In optical character reader systems the individual characters of the character string image given on a paper shall be separated for recognition. For properly sectioning the individual characters the correct character pitch must be determined first. The present character pitch detector apparatus and method detects a plurality of character lumps from series of character string images. Then the distance between character lumps is calculated and a frequency distribution of said distance between character lumps is stored. Further a presence section of the candidate character pitches is forecasted by means of the mean height of said character lumps and said frequency distribution is divided into a plurality of errors by means of said candidate character pitch included in said presence section. By calculating a character pitch estimation error and an estimation error appreciation standard constituted of an optimum linear sum of said character pitch estimation error and further selecting a candidate character pitch minimizing said estimation error appreciation standard an optimum character pitch is selected. The present apparatus and method is applicable even if said series of character string images comprise characters which touch each other and even if said images are of poor print quality.

Abstract: A rule invocation mechanism in an inductive learning engine employing symbolic rules for characterizing a sequence of time-related events. The rules to be tested as hypotheses against new events in the sequence are ranked according to their information content or "quality" value. The efficiency of the rule-to-event pattern matching process for characterizing the new events is increased by not testing a hypothesis if a much better hypothesis already exists. Those hypotheses that characterize events in the sequence are tagged to the event.
