Abstract: A position-resolving sensor for detecting individual light flashes with a multiplicity of adjacent light-receiving elements and an evaluating circuit which determines the light-receiving element which is struck by a light flash. The sensor comprises light-receiving elements subdivided into a plurality of groups such that each light-receiving element is exclusively adjacent to light-receiving elements belonging to other groups. Each group of light-receiving elements is associated with a row of light detectors and at least one optical connecting element establishes a light-conducting connection between each individual light-receiving element and light detectors which are selected in accordance with a given code from the assigned row of light detectors. A high solid-angle resolution can be achieved with few light detectors. In addition, that order number of the light-receiving element is read out which has registered the light flash, directly in a digital code.

Abstract: The determination of the orientation parameters of a missile by means of a three-line scanner requires the generation of scanning traces which are oriented at a specific angle with respect to the direction of flight. In the present invention the scanning traces are produced with a two or four part scanning prism, whose reflecting surfaces are arranged at a specific angel .beta. with respect to the axis of rotation of the scanning prism.

Abstract: In an arrangement for combatting ground targets by a projectile launched m a flying weapons carrier, a launching device is located in the weapons carrier for directing the projectile in a downward and rearwardly inclined direction relative to the flight direction of the weapons carrier. An aiming system connected to control units adjusts the horizontal velocity of the weapons carrier to the same magnitude as the oppositely directed ejection velocity of the projectile. The projectile can be released in the nadir above the target.

Abstract: An apparatus for the fragmentation of a solid body surrounded by a fluid, in particular in a living being, by means of acoustic shock waves which are induced by the light of a laser. A reflector for acoustic waves focuses the shock waves onto the body. In the region of the reflector, an element is provided which consists of a material absorbing the laser light, and onto which the laser light is directed, so that the plasma state triggering the acoustic shock wave develops at the surface of the element. The apparatus thus has the advantage that even under unfavorable conditions acoustic shock waves can be generated with certainty at every laser pulse.

Abstract: A safety device for use in low-speed aerodynamic bodies. The pressure conditions at the outer contour of the flying equipment are used for obtaining an arming criterion of a fuse. A slide is movable from a safe to an armed position. In the safe position, slide pickup ports are within the internal contour of the body. In the armed position, the slide pickup ports are exposed to the air stream outside the external contour of the body for creating a pressure difference for arming the fuse.

At the object several light sources are located, each intensity-modulated with a different code frequency. Optics of the measuring device reproduce the object on a position-sensitive detector. On the basis of its output signals, the image coordinates of the light sources are computed by way of an evaluating device using a frequency multiplexing process.

The undercarriage contains, in combination with hollow profile wheels in the wheel sets and primary elastic springs in the longitudinal direction, two lever systems which are self-adjusting, independent of each other and are arranged on the longitudinal sides of an undercarriage. The lever systems forcibly couple the axle ends of the wheel sets on the same rail in the longitudinal direction of the undercarriage and are movable only in opposite directions.

Abstract: A strapdown measuring unit for measuring the angular velocities about the three axes of a flying body rotating relatively fast about its first axis is disclosed. The unit combines a Sagnac effect sensor for roll rate determination and two micro-mechanical acceleration sensors whose output, combined mathematically with the output of the Sagnac effect sensor, determines the angular velocity of the remaining two axes. The mathematical calculations are performed by a dedicated microprocessor which is integrated with the three sensors into a single small unit.

Abstract: A missile with adjustable flight controls capable of altering the missile's flight path is disclosed. The missile comprises an electric generator and control electronics. The electric generator is used in this invention both to provide electrical power to the control electronics and to regulate the flight controls. A mechanical connection is created between the generators rotor and the flight controls. The generator is electrically coupled to the control electronics through an electrically variable load. The control electronics alters the load which varies the rotational speed of the generator. This in turn affects the flight controls and the flight path is altered accordingly. The invention is small and compact, allowing its use in small missiles such as mortar or artillery shells.

Abstract: A frequency-selective sound transducer comprised of a number of resonators with differing but sequential natural frequencies arranged in a first plane. A deformable membrane is arranged in a second plane, parallel to the first plane and in close proximity thereto. A small air gap thus exists between the first and second planes. Sound waves produce vibratory motion in the membrane, which motion is transmitted to the resonators by pressure waves generated by the membrane in the air between the membrane and resonators. The deflections of the resonators are converted into electrical signals.

Abstract: This method serves for calibrating gyros forming part of the attitude control system of a satellite stabilized in three axes and which have an unknown drift. A two-axis sensor measuring the direction of a radiating reference object in the coordinate system x, y, z fixed with respect to the satellite is used. Two reference attitudes each different with respect to the reference object are commanded to the satellite in the course of two consecutive time intervals spaced from each other. The values measured by the sensor representing the respective actual direction of the reference object are recorded at the start and at the end of the time intervals. The respective time integrals of the gyro output signals are computed during the time intervals, which represent the gyro drift plus the respective instantaneous satellite deviation from the commanded reference attitude. Finally the gyro drift is determined from these time integrals and the values measured by the sensor.

The integration time for imaging a radiation source is increased due to the rotation of the prism in a direction opposite the track or flight direction.
