Patent DE-4407870-A1 (DE)
Title: Switch chamber under vacuum functional reliability evaluation method
Inventor: LEBEK ALEXANDER DR
IPC: H02B13/065
Filed: 1994-03-04
Abstract: The method involves feeding power from a source (1) for the measurement to the unloaded switching chamber (2), e.g. a vacuum switch, over a limited period during mechanical opening or closing. The time variation of the discharge between the switch parts is detected, using a coupled inductor coil (4), by a measurement and storage appts. (6). At least two characteristic parameters extracted from the variation are compared with defined values and parameters derived for evaluation of the functional reliability. The characteristic parameters can be coupled with an additional quality parameter for the evaluation of the functional reliability. The characteristic parameters can be the maximum amplitude and the duration of the discharge.

IPC: G01R31/08
Filed: 1994-03-22
Abstract: Un dispositif de contrôle de câbles comprend un générateur d'impulsions qui fournit, en tant que signaux de contrôle, des impulsions au câble à contrôler, un amplificateur dont la borne d'entrée reçoit les signaux d'impulsions réfléchis, un comparateur et une unité de commande et d'évaluation qui déduit du signal de sortie du comparateur la durée de propagation du signal jusqu'à un point déféctueux du câble. Afin de détecter une pluralité de points déféctueux du câble mutuellement espacés, l'unité de commande et d'évaluation commande le générateur d'impulsions de sorte que celui-ci fournisse successivement au câble une série d'impulsions. L'unité de commande et d'évaluation n'évalue les signaux réfléchis que pendant une fenêtre de temps dont le commencement est retardé d'un temps de temporisation TLi par rapport à l'impulsion correspondante (I) et dont la largeur est égale à Ti. Les temps de temporisation varient de sorte que les fenêtres de temps chevauchent au moins partiellement la plage de durées de propagation des signaux dans la partie du câble à contrôler. Un circuit générateur de valeurs de comparaison connecté entre l'amplificateur et le comparateur détermine une valeur de comparaison par dérivation à partir du signal d'impulsion réfléchi qu'il reçoit au commencement de la fenêtre de temps. Cette valeur de comparaison est transmise au comparateur de sorte que la réponse d'impulsion du signal non perturbé soit à peu près compensée.

Filed: 1994-05-12
Abstract: A combined recursive/transverse filter has an input element (E) and several integrating elements (I1 to In). The output signals of the integrating elements (I) to (In) are supplied to the inputs of two adders, each formed of individual adder elements AA and AB. In addition, each adder has a load element (L1 or L2). The output of the adding elements of each adder are combined and connected to the output of a corresponding load element (L1, L2). The output signal of each adder is supplied to the non-inverting input (-) of the respective load element. All elements are designed as voltage-controlled current sources connected to a downstream device which calculates the arithmetic difference between the output currents. Such a transconductance amplifier may also form a cell, and an amplifier may be formed of a combination of several parallel connected cells. The individual cells may be switched on and off by binary signals, making it possible to obtain programmable filtering structures.
