Abstract: A membrane for a cover for closing a container having the general form of a cylinder and being compressible in the direction of the axis of the cylinder. The membrane comprises two mutually parallel, generally flat parts arranged to move axially in relation to each other guided in the movement by guiding elements; resilient element arranged to generate a counterforce between the flat parts during compression of the membrane in the direction of the axis; at least a first and a second electrical contact device operated by the axial movement between the circular parts, the combined electrical settings of which contact devices will carry information about the compressions and decompressions of the membrane and elements for presenting the settings to the outside of the membrane. A cover comprising such a membrane and use thereof are also described.

Abstract: A circuit arrangement of a video sensor chip has photosensitive pixels arranged in a matrix, each pixel having a phototransistor whose output photoelectric current is amplified logarithmically and sent as a voltage signal to an analyzer circuit.

Abstract: A method is proposed which serves to control the focusing of a light beam, aimed at a rotating recording medium (25) for reading data, of a scanner (15, 20) onto the recording medium (25) and the guidance of the light beam along the data tracks of the recording medium (25), each by means of a respective control circuit. The scanner (15, 20) and the recording medium (25) are mounted on a fundamental substrate (10) in at least one housing (1), and the at least one housing (1), together with the fundamental substrate (10), the scanner (15, 20) and the recording medium (25), forms a coupled mechanical oscillator, which is vibrated as a function of a vibration spectrum (75); the scanner (15, 20) is accelerated by the vibration and a relative motion of the recording medium (25) with respect to the scanner (15, 20) is effected, and the amplitudes of the relative motion and the accelerations have a frequency response.

Abstract: A device for regulating a light width of headlights of motor vehicles comprises an adjusting device associated with one of the headlights, a transmitter which emits electromagnetic radiation to illuminate a region of a roadway located in front of the motor vehicle, an opto-electronic sensor which determines radiation emitted by the transmitter and reflected by the roadway and in dependence on the detected radiation produces signals, an evaluating device which processes the produced signals and controls the adjusting device for maintaining constant a light width of a beam emitted by the headlights.

Abstract: The angular speed measuring device has two acceleration sensors mounted on a circular plate rotating about a first rotation axis and each sensor generates a signal depending on a Coriolis force produced when it rotates about two additional rotation axes. The rotation axes are orthogonal and the acceleration sensors are at least partially made of silicon and displaced by 180.degree. on the planar plate. An initial signal processing device is mounted directly on a circular planar plate on which the acceleration sensors are mounted. A light emitting diode is used to transmit the signals from the initial signal processing circuit to a signal processing circuit off the planar plate via a photodiode receiving device.

Abstract: Proposed is a compensation scale (10) in which at least one acceleration sensor (24, 25) is disposed at a movable component (14) of the scale (10) and puts out a signal to a correction signal processing arrangement (50) which determines at least one correction signal (53, 54, 56) for influencing the measuring result that appears at the output (43) as a measure for the weight or the mass (m) of the load (15) with which the movable component (14) was charged. The correction signals (53, 54, 56) eliminate the influence of translatory and rotatory interference accelerations (y, .THETA.) which act on the base plate (11) of the scale and, without being corrected, would falsify the measuring result (43) or at least unduly extend the measuring time.

Abstract: A color television camera has a semiconductor image sensor composed of sensor elements of the CCD type arranged in a raster. The charges produced in the sensor elements within an integration interval are read out as video signals. The image on the semiconductor image sensor is shifted in the horizontal direction by a fraction of a raster unit of measurement from one integration interval to the next integration interval in a cyclical fashion. An increase of the resolution in the vertical direction will then result by reading out the video signals from the semiconductor image sensor. The horizontal image shift is produced in the optical path between the objective lens of the image sensor by means of filter disk mounted so as to be bistable. The filter disk can thereby be flipped through a predetermined angle and back between integration intervals of the image sensor.

Abstract: The suspension of movable system instruments, for example, a galvanometer, introduces elastic reset torques upon deflection. To compensate for such torques and render the apparatus essentially independent of the deflection torques, an opto-electronic device provides an output signal representative of the deflection which is combined with the deflection voltage applied to the galvanometer to at least in part compensate for the reset torque introduced by the moving system suspension.
