Abstract: An efficient coding method of coding video signals, speech signals and the like at a lesser amount of bit rate and a decoding method of performing inverse transformation thereof for digital transmission or recording. In accordance with the present invention, in the coding method, a block made up of a plurality of input data for an input signal is used as an encoding unit, a maximum SX and a minimum SN of predictive errors corresponding to differences between the input data of the block and its prediction value are computed, a predetermined value larger than a data (SX - SN) is used as a divisor data OU, modulos E obtained by dividing the respective input data of the block by said divisor data OU are encoded, and additional codes including predictive error information on said data SX, SN and OU as well as encoded codes of said modulos E are both transmitted. In the decoding method, information (the maximum SX and minimum SN of predictive errors) on the predictive error presence range and the divisor data OU as a remainder are obtained directly or indirectly on the basis of the transmitted additional codes. As a result, offsets (integer multiple of the divisor data OU) obtained through divisor in the coding operation can be rightly and uniquely determined in the decoding operation and when the offsets are added to the transmitted modulos E, the   input data can be perfectly reproduced. That is, any anomaly errors can be totally eliminated.

Abstract: A CMOS logic circuit for converting a low voltage logic signal with a range 0-VCC into a high voltage logic signal with a range 0-VPP, which may be entirely made with enhancement-type transistors, comprises an additional p-­channel, decoupling transistor (P6) functionally connected in series with the p-channel transistor (P1) of the CMOS circuit which is connected to the high voltage node VPP and the additional decoupling transistor is driven by a bias voltage tied to the VPP voltage and lower than the latter by a certain preset value. The so-called gated breakdown of p-­channel transistors is effectively prevented and furthermore these circuits, destined to operate under a high supply voltage, may be fabricated through a normal CMOS fabrication process not requiring particular fabrication techniques for the p-channel transistors subject to gated breakdown conditions or the formation of depletion-type transistors and without the use of special circuits which require oscillator generated driving signals.

Title: RDS broadcast receiver with device for automatically switching over to an alternative regional programme
Inventor: BAUER JOERG DIPL-ING GRUNDIG E
IPC: H04H20/00
Filed: 1990-08-06
Abstract: In the radio data system, transmitting stations having the same programme identify themselves by transmitting the same PI code. If the programme is regionalised at particular times of the day within one programme chain, the PI code should be switched over. However, there are transmitting stations which always radiate a regionalised PI code, even when they are transmitting a joint general programme at times via the individual transmitting stations. To avoid an additional operating control at the RDS receiver which can lead to operating errors, a mobile RDS receiving set is presented in which, when a regional programme chain is lost, the alternative frequencies stored from earlier receiving routines are examined to see whether another regional programme of the same transmitting station can be received which is then tuned in by preference and is accepted as part of a new programme chain. <IMAGE>

Abstract: The purpose of the present invention is to offer a multi-play liquid crystal device for black and white and multicolor applications, which is set free from any parallax effect, having a very width view angle at least as in a cathode-ray tube. The problem of parallax was solved by a new concept termed STL, which is the root of the invention. 
     Due to the STL concept, a new system was found out termed STAL, which allow to obtain high resolution liquid crystal devices without the use of the unreasonable expensive active matrix technology. It is achieved by means of simultane energizing different electrode lattices on independent liquid crystal displays, which are juxtaposed afterwards on a common light scattering surface or a common large screen.

Abstract: In a video tape recording and/or reproducing apparatus, a tape tension servo-system detects tape tension between a supply reel (71) propelled by a voltage driven motor (72) and the head drum to provide a corresponding detected tension signal supplied to a processor (1) which is periodically interrupted (INT) for providing a control signal proportional to any deviation of the detected tape tension from a desired value and further for providing differential and integral control signals determined from the proportional control signal at successive interruptions and which are combined to form a control voltage signal for the supply reel motor (72). The processor is desirably constituted by a universal pulse processor (2) and a central processing unit (1). The tape tension is detected by an angularly movable arm (75,78) carrying a post about which the tape is wrapped sufficiently to ensure good compliance. The detecting arm and post are of light weight materials so as to be readily responsive to changes in tension and are arranged so that angular displacements of the area are not influenced by gravity.

Abstract: According to the invention, a chemically adsorbing material (1) is reacted with a substrate (4) surface having active hydrogen groups by dipping the substrate (4) into a solution (2) of the chemically adsorbing material (1) simultaneous and applying ultrasonic waves to the solution (2) by an ultrasonic washer (3). In this way, a high concentration monomolecular and/or polymer film (5) substantially free from pin holes can be formed in a short period of time. That is, while the ultrasonic waves are applied, a chemical adsorbing material (1) having an end functional chlorosilyl group is adsorbed onto the substrate surface (4), thereby forming a chemically adsorbed monomolecular and/or polymer film (5). The frequency of the ultrasonic waves are suitably in a range of 25 to 50 kHz. In addition, after formation of the adsorbed film (5), the substrate (4) is washed for making monomolecular film by dipping it in a washing solution while applying ultrasonic waves. In this way, non-reacted chemical adsorbing material (1) remaining on the substrate (4) can be efficiently washed away.

Abstract: A method and apparatus controlling the generation of a shadow-process in a multi-computer system. When the real-process (40) requests a service from the operating system (36) of a first computer (32), it is decided if the requested service is an update instruction to external data of the real-process or for remote execution of a process on another computer. If so, it is then determined if the shadow-process (44) was already generated during execution of the real-process. If the shadow-process was not previously generated, the operating system generates the shadow-process in a second computer (34) and then copies state information to the second computer (34) at predetermined intervals. If the real-process does not initiate a request for service constituting such an update instruction or remote execution at all, execution of the real-process (40) is completed without generating the shadow-process (44).

Abstract: A high-frequency, high-leakage-reactance transformer has a section of low-permeability magnetic material disposed between planar primary and secondary windings. The low-permeability section provides a controlled flux path for the leakage flux between the primary and secondary windings. Excessive eddy currents are thus prevented from flowing in the planar windings, and high-efficiency operation is achieved. The high-leakage-reactance transformer can function both as a transformer and an inductor, thereby reducing the size of, for example, a resonant power supply or a discharge lamp ballast.

Abstract: The location independent personal telecommunications system of the present invention enables a subscriber to have a single personal telephone directory number. When that personal telephone number is dialed, the system uses the existing public and cellular communication systems and a service node all comprising parts of the personal telecommunications system to route the call to the present, or last known location of the subscriber. The location of the subscriber is determined by the personal telecommunications system through a radio tracking system comprised of a number of radio base stations that monitor the subscriber's location by communicating with a personal communicator carried by the subscriber. The subscriber location information is transmitted from the base stations to the service node for storage and subsequent access when a call is placed to the subscriber's personal telephone number. The service node will then transfer the call to the proper telephone number at the location where the subscriber is currently, or last known to be located, or if not at a fixed location with a known phone, notify the subscriber through the base stations and the personal communicator of the incoming call.
