Abstract: The invention relates to a device for the representation of braille writing, which is composed of modules (10), each of which has an upper part (12) with a stationary support plate (28) for touch-pins and a lower support (30) which is arranged to be vertically adjustable relative to the upper part and by means of which the spring-loaded touch-pins which are guided in a cover plate (14) can be raised above the outer surface (16) of the latter or lowered beneath it. The position of the support (30) relative to the upper part (12) can be variably adjusted by means of a cam, either manually or by a motor. The support (30) has platforms (32) assigned to the bottom surfaces (26) of the touch-pins (18), these platforms being in particular staggered in the manner of steps. Channels or grooves (36) are provided in the support at the same height as the platforms and retain and/or guide locking elements which extend transversely to the guide bushes (34) for the touch-pins. These locking elements may be anchor tappets (40) in magnetic coils (38) or piezoceramic bending strips (50). <IMAGE>

Abstract: An optical detection system for detecting a displacement amount of a movable device with an optical encoder movable in accordance with a movement of the movable device. The optical encoder (16) has on a light-reflecting layer a plurality of pits (20) successively strung in a predetermined direction. An optical pickup optically picks up the pit information by irradiating the optical encoder with light beams and receiving reflected light beams from the optical encoder. The optical pickup comprises a light-division device for dividing the light beam from a light-emitting device into three light beams so that the divided three light beams are directed to the pit string (24-27) to apply three light spots to the pit string. The light-division device is adapted to be rotatable with respect to the optical encoder so that a light passing through the three light spots intersects the pit string at a predetermined angle. The reflected light beams due to the outside light spots are respectively incident on two photosensitive elements each generating an electrical signal. The electrical signals from the photosensitive elements are out-of-phase by an amount corresponding to the rotation of the light-division device and fed to a detection circuit to detect information of the movement of the movable device and produce a pit detection signal indicative of the information.

Abstract: In an encoder device which is for use in combination with a decoder device in a communication system and which encodes a sequence of digital speech signals into a sequence of output signals by the use of a spectrum parameter and a pitch parameter, a subsidiary parameter of the digital speech signals is detected and by a monitoring circuit to classify the digital speech signals into a voiced sound and a voiceless sound or into vocality, nasal, fricative, and explosive at every frame. On detection of the voiced sound or the vocality, a predetermined number of excitation pulses are calculated only during a representative subframe after dividing each frame into a plurality of subframes by the use of the pitch parameter and are produced as primary sound source signals together with a subsidiary information signal which is produced during the remaining subframes and which may be representative of a correction factor of an amplitude and a phase in each of the subframes. On detection of the voiceless sound or the nasal, the fricative, and the explosive, noise signals and/or a plurality of excitation pulses are calculated for each frame and produced as secondary sound source signals. Alternatively, the subsidiary parameter may represent periodicity of an impulse response of a synthesizing filter formed by the spectrum parameter.

Abstract: In a digital VTR, supplied digital video information is separated into 0th to second stage data by an information separating circuit (300) employing a hierarchical coding method. The 0th stage data are subjected to processes such as error correction as main information capable of roughly forming video signals by themselves. The first and second stage data are subjected to error correction and the like as subinformation forming details of the image. The main information and the subinformation are recorded on a magnetic tape such that the main information is recorded at the central portion of each recording track and the subinformation is recorded on both outer side portions of the recording track. During high speed reproduction, at least the main information is reproduced from the magnetic tape and rough video information is formed based on the reproduced main information.

Abstract: An apparatus and method for tachyarrhythmia rever­sion uses multiple sensitivities programmed for automatic operation. A first (medium) sensitivity is used normally for the detection of sinus rhythm and ventricular tachycar­dia. A second (higher) sensitivity is designed for differ­entiating ventricular fibrillation from asystole. A third (lower) sensitivity can also be programmed into the device to differentiate between R-waves and high amplitude current of injury T-waves which may occur post shock. Following the delivery of antitachycardia therapy in the form of either antitachycardia pacing therapy or cardioversion shock the­rapy, there is a pause, or post therapy pacing delay for a period of time prior to the commencement of bradycardia support pacing. The magnitude of the delay period is sub­stantially greater than the normal bradycardia support pacing standby interval.

IPC: G06K11/06
Filed: 1989-06-23
Abstract: A touch screen overlay for use on the viewing surface of a visual display device formed from a flexible membrane laminate having improved conductor durability. The flexible laminate comprises first and second flexible substrates formed of transparent polyester material. An array of parallel transparent conductors is deposited on a surface of each flexible substrate. The two flexible substrates are joined together by an adhesive sheet of polyester material. The substrates are joined so that transparent conductors are deposited on the surface of each flexible substrate which faces away from the viewing surface when the overlay is attached to the visual display device. The two arrays, when so superimposed, form a grid-like pattern, separated by the thickness of the upper one of the flexible substrates and the adhesive sheet. A third flexible substrate also formed of polyester material covers the surface of the upper one of the other flexible substrates carrying the upper array of parallel conductors. The second and third flexible substrates are also joined by an adhesive sheet of polyester material. When the overlay is contacted either by finger touch or by a stylus, the transparent conductors located in the laminated below the contact area will subjected substantially only to compression forces.

Abstract: A driving force distribution control system for a 4WD vehicle includes a torque distributing clutch for varying a driving force transmitted to secondary drive wheels such as front wheels in response to a control signal, sensors for determining a vehicle speed (108) and a wheel speed difference (107) between the sensed speed of the primary drive wheels (103) such as the rear wheels and the sensed speed of the secondary drive wheels (105), and a controller for producing the control signal. The controller determines a, correction quantity which increases as the vehicle speed increases, further determines a corrected wheel speed difference by subtracting the correction quantity from the measured wheel speed difference in order to eliminate an undesired influence of a tire diameter difference between the front and rear wheels, and produces the control signal in accordance with the corrected wheel speed difference.
