Patent EP-0489310-A1 (EP)
Inventor: GROSS CLIFFORD
IPC: B60N2/90
Filed: 1991-11-21
Abstract: An electronic system for adjusting a load bearing surface (12) such as a chair or bed to provide a desired level of comfort comprises an array of pressure sensors (14) located within the load bearing surface. The pressure sensors (14) generate data indicating the actual distribution of pressure exerted by a user on the load bearing surface. An electronic processor (40) processes the data generated by the array of pressure sensors (14). The processor (40) compares the fraction of total load exerted on each of a plurality of regions of the load bearing surface (12) with a desired range for each region. If the fraction of total load for any region is not within the desired range, a servo-mechanism (28) is activated to change the shape of the load bearing surface (12) so that the fraction of total load on each region is within the desired range, so as to provide a desired level of comfort to the user.

Abstract: An asynchronous transfer mode switching arrangement comprises a serial to parallel converter arranged to receive input packets of data, which include routing information, in serial form and convert the packets of data to parallel form. A random access memory is provided in which each packet of data is entered at an addressed location into the memory, and the address is entered in a respective first-in first-out output queue at the tail. The address at the head of the queue is accessed and the packet of data is read from the random access memory into a parallel to serial converter and the packet of data is serially delivered to the associated output. The random access memory and the output queues are controlled by a memory management arrangement to which is connected a broadcast channel routine random access memory. The memory management arrangement addresses the broadcast channel routine random access memory with channel index information, and receives information identifying the required output ports.

Abstract: The invention refers to a generic, digitally controlled bioelectric signal amplifier for use in computerized electrophysiological systems. It offers a solution for a broad range of adjustment of high and low pass filtering with circuits that occupy a small volume. In case of fixed gain amplifiers, such as those used for ECG and EEG, a simple solution is proposed for the reduction of recovery time after an out of range input. The amplifier comprises four blocks : 10, 20, 30 ,40. Original solutions are included in the design of blocks 20 and 40. Block (20) is a high pass filter that with the next amplifier stage contains a feedback circuit. This close loop multiplies the RC time constant by a coefficient of a value greater than 1 for input levels inside the range and less than 1 for out of range input levels. The last block (40) is formed by a sweepable switched capacitor low pass filter. Block (10) is a pre-amplifier and block (30) is a third amplification stage.

Abstract: De nouveaux anticorps monoclonaux oligomères avec une avidité élevée pour des antigènes, typiquement de la classe de IgG, sont séctrétés avec deux ou plusieurs monomères associés d'immunoglobuline de façon à former des molécules tétravalentes ou hexavalentes d'IgG. On peut former les oligomères en reproduisant essentiellement des régions de la chaîne légère, notamment la région variable. Les anticorps oligomères de l'isotype de l'IgG traversent le placenta et peuvent transmettre une immunité passive à un foetus, ce qui est particulièrement important pour protéger des nouveaux-nés contre des agents pathogènes tels que des streptocoques du groupe B.

Abstract: Des signaux tels que des signaux de télévision sont répartis à partir d'une station d'extrémité de tête (1) par l'intermédiaire d'un réseau de fibres (3). Les signaux sont modulés en amplitude sur des porteuses à différentes fréquences, et les différentes porteuses sont combinées afin de former un signal analogique composite. Dans la station d'extrémité de tête (1) le signal analogique composite est écrêté afin de réduire le rapport crêtes/moyenne et le signal composite écrêté est numérisé. Les données numériques obtenues sont transmises par le réseau de fibre et elles sont recues par un récepteur optique (2). Ledit récepteur optique (2) reconstitue le signal analogique composite pour permettre sa réception par une terminaison. Dans un exemple, le signal analogique composite a une largeur de bande d'une octave ou moins, et il est numérisé par échantillonnage à une cadence d'échantillonnage inférieure à la cadence de Nyquist.

De préférence, le corps en nid d'abeilles se compose d'au moins deux piles de tôles (51, 52) dont les extrémités sont imbriquées. On fabrique de préférence un tel corps (50) en nid d'abeilles à partir de tôles lisses (51) et de tôles (52) avec des ondulations ayant des hauteurs et des largeurs diverses dans différentes régions.

Abstract: The control device (14) has a reversing valve (12) which is arranged in fuel lines, into which a feed pump (13) is fitted, between a fuel tank (67) and the suction space (61) of a fuel injection pump (11) and by means of which, to stop an internal combustion engine operated by means of the fuel injection pump, the interconnections between the lines can be altered in such a way that the suction space (61) is connected to the suction side of the feed pump (13) and the delivery side of the feed pump is connected to the fuel tank (67). The valve member of the reversing valve (12) is a slide (16) which carries two double seat valve closing bodies (33, 34) which interact with corresponding valve seats (39, 40; 41, 42). The double seat valve closing bodies (33, 34) form sealing elements which are attached releasably to the slide (16) and are composed of an elastically deformable material. The sealing elements (33, 34) are provided with sealing lips (37) which point towards the valve seats and are elastically deformable, with the result that, even in the case of dimensional deviations due to manufacturing tolerances, both valve seats (39, 41 and 40, 42 respectively) are in each case reliably sealed off.
