Abstract: A voltage divider comprising two identical resistors (R₀) is arranged between the bases (3, 4) of two first tran­sistors (T₀₁, T₀₂) arranged as a differential pair, each having a first emitter area (e₀), the junction point of said resistors (R₀) being connected to the base of a second transistor (T₁) having a second emitter area (2e₁), whose emitter, like that of the first transistors (T₀₁, T₀₂), is connected to a current source (6). For a ratio between the second and the first emitter areas (2e₁; e₀) equal to 4:1 the difference between the output currents (I₁, I₃) of the first transistors (T₀₁, T₀₂) increases as a linear function of the input voltage over an as large as possible range.

Abstract: For enhancing the contrast of a picture on a projection screen (26) derived from a liquid crystal display (16), the analyzer (22) which is normally part of the liquid display unit (16) is incorporated either in front (22b) of or in back (22f) of the screen (26) relative to the viewing area or may constitute a layer (22c) between the front and rear portion of the screen (26). In any of these positions, the presence of the analyzer (22) will result in darker dark portions and therefore in enhanced contrast. When used in front of the screen (26) relative to the viewing area, protection of the lenticular surface (30) also results.

Abstract: L'invention concerne la transmission de signaux logiques.Le circuit comprend un accès D connecté à une ligne de transmission de signaux logiques unipolaires et un accès (D<sub>+</sub>, D<sub>-</sub>) connecté à une paire de fils de transmission de signaux logiques différentiels. Des générateurs de courant (T4,T5) émettent un signal différentiel positif quand un signal logique unipolaire "bas" est appliqué à l'accès D. Lorsque le signal différentiel reçu en (D+,D-) doit être transmis sur l'accès D par un niveau "bas", le signal significatif du niveau bas reste supérieur au niveau de tension V<sub>L1</sub> en dessous duquel les générateurs de tension sont activés, pour empêcher tout blocage du circuit par bouclage des signaux dans le circuit.Application au multiplexage de la circulation des informations traitées dans un véhicule automobile.

Abstract: Un dispositif de transfert de puissance permet le transfert régulé de puissance depuis un bloc électrique (100, 300) à une carte de données portative sans contact (200) sans qu'il soit nécessaire de prévoir des circuits de régulation sur la carte elle-même. Le bloc électrique comporte une bobine primaire (101) permettant le couplage magnétique de la puissance à une bobine secondaire (101) située sur la carte, lorsque la carte de données est mise en rapport étroit avec le bloc électrique. Le dispositif comporte un microprocesseur (310), un amplificateur de puissance (130) avec la bobine primaire (101), une source de tension variable (320) et un appareil pour mesurer le flux de courant dans la bobine primaire (120). Lorsque la carte de données portative n'est pas mise en rapport étroit avec le bloc électrique, le microprocesseur fait en sorte que la source de tension variable émette une séquence de tensions par paliers. Le flux de courant actif est mesuré à chaque palier et stocké dans la mémoire. La puissance fournie à la carte de données est calculée en fonction de la différence entre les courants actif et de repos, multipliés par la valeur de la source de tension variable. Les mesures séquentielles de courant actif continuent jusqu'à ce que la valeur calculée de la puissance fournie à la carte de crédit dépasse une puissance de seuil prédéterminée, moment auquel la carte de données reçoit une quantité de puissance précise et prédéterminée.

Abstract: This arrangement is based on the duplex concurrence principle with two closely coupled but spatially separable computers of identical construction and loaded with corresponding programmes and connectable to common or redundant input channels and to a common output channel. The two computers are multiprocessors. A device is described which synchronises the two identical computers so closely that both computers execute their programmes in step with the clock. In addition, the device allows the input data and the interrupts to be matched, an empty processor to be trained after it has been repaired and various functions for acquiring and dropping synchronisation in non-deterministic operations. The device utilises special properties of the buses of the two multiprocessors, which are also described. <IMAGE>

IPC: H05B3/00
Filed: 1988-09-20
Abstract: In order to avoid overheating of heating resistors, it is known that the current flowing continuously through the heating resistor can be measured using a shunt resistor. If the current falls below a value representing a permissible limiting temperature (TG), the current is then only applied to the heating resistor (RH) in pulses. The invention proposes to utilise the temperature dependence of the heating resistor (RH) and to arrange the heating resistor (RH) in a resistance bridge circuit. The resistance bridge circuit (WB) is connected to a direct voltage (UB) via a switching device (SR). The bridge voltage is fed to a comparator circuit (V1). The switching device (SR) is controlled as a function of the output state of this comparator circuit (V1) via a control device (ST). The invention has the advantage of more exact temperature measurement since the resistors in the feed line to the heating resistor do not have a disturbing effect. <IMAGE>

Abstract: The invention relates to an air mattress (1) comprising a number of successive, elongate and bag-like elements, which can be filled with gas such as air or with some other flowing medium. The elements are ar­ranged transversally with respect to the lengthwise axis (D - D) of the mattress and/or the bed, and are connected to each other successively in a band-like fashion. The successive elements (2, 2′) are arranged so that the lenghtwise seam joints (6; 6b) of the ele­mentes are located at given intervals in the bottom part (1b) of the mattress, and that the areas between these seam joints are arranged to form structures which are directed upwards from the bottom part (1b) of the mattress. 
     The invention also relates to a method for adjusting an air mattress or the like. The elements (2, 2′; 9, 10) of the mattress are partly filled with for instance air, so that the mattress pressure cor­responds to the pressure of the surroundings when the mattress elements are not subjected to a weight load, but the mattress pressure grows in a known fashion according to the weight load of the human body or part thereof, so that the mattress elements conform to the contours of the body or part thereof, and simultaneously the surface pressure against the body or part thereof is distributed evenly over the whole body or part there­of.

Abstract: The invention relates to semiconductor protection components, thyristors or triacs. These components do not usually include a gate electrode and are triggered by an overvoltage between the main electrodes. For situations in which it is nevertheless desired to also have triggering by a gate current, the invention proposes a structure with narrowed gate region (portion D) and overdoped central region (22) beneath a portion of the emitter (18). This structure avoids having too large a gate current for triggering the thyristor and too small a holding current once it is triggered.
