Title: Procédé de détection photoélectrique avec réduction de rémanence de photo-transistor, notamment de type NIPIN
Inventor: BERGER JEAN-LUC
IPC: H04N5/374
Filed: 1989-10-10
Abstract: L'invention concerne les matrices photosensibles, et tout particulièrement celles qui utilisent des phottransistors en silicium amorphe de type NIPIN ou PINIP. Pour éviter des problèmes de rémanence dus à l'accumulation de trous dans la base après une phase d'éclairement, on propose selon l'invention de faire suivre l'étape de lecture du signal d'éclairement d'une étape d'effacement de rémanence consistant à rendre conducteur le phototransistor (PHT) en polarisation directe ou inverse, de manière à injecter dans la base des électrons qui élimineront les trous par recombinaison. La mise en conduction par polarisation inverse s'avère meilleure que la mise en conduction par polarisation directe. L'invention est applicable notamment à une structure matricielle de lignes (Li) et colonnes (Cj) de sites photosensibles (Pij) dans laquelle chaque site est consitué par un phototransistor NIPIN en silicium amorphe (PHT), en série avec une diode de lecture (DL) pouvant être mise en conduction inverse.

Date Jun. 29, 1989.A method for determining the flow situation in a transport system where the flow medium occurs in multi-phase and is conducted through a structural detail such as a choke valve, which acts on the flow of the medium and produces turbulence causing acoustic energy signals which are generated in and immediately close to the structural detail. The acoustic energy signals are sensed by one or a plurality of acoustic sensors with an acoustic broad-band connection with the structural detail. The sensor converts the energy signal to transmittable signals to a signal processing unit utilizing known signal analysis principles to provide interpretable information on the actual flow situation and the flowing medium which is influenced by the structural detail. The structural detail to which the acoustic sensor is connected may be incorporated in a subsea production system.

Abstract: An electromagnetic flowmeter with conventional orthogonal electrode and magnetic axes (x, y) intersecting the flowtube axis (z) has its electrodes constituted by two pairs (1, 2, and 3, 4) of electrodes mounted in insulating tubing (5) on each side of the flow passage through the tubing. Four conductors extend respectively from the four electrodes to enable the potential difference between the two electrodes on each side due to an axial component on each side of eddy current electric field in the liquid to be determined for self-calibration purposes in compensating automatically for any extraneous change in the magnetic field and the average potential of each pair of electrodes can also be determined to derive the velocity of flow of the liquid. One of the two pairs of electrodes can be replaced by a single electrode. The electrodes can be point electrodes or electrodes of substantial area and methods are described for mathematically adapting various types of electrodes to the required purpose and to eddy currents in parts of the assembly. The invention can also be applied to an eddy current probe for giving readings of sensitivy at a conventional flowmeter.
