Abstract: A portable electronic device for orientation and communication comprises a casing (2) which includes a portable computer (8) with an integrated operating surface (10), communication means comprising electronic assemblies for wireless communication with identical or similar devices, and a docking station (6) for electrically connecting the computer to the communication means and the electronic assemblies and for mechanical retention. The computer (8) and the electronic assemblies are housed in the casing to be protected against outside influences and the computer is designed to be removable from the casing for operation independently of the device.

Abstract: A system for controlling vehicles in which stored information, information obtained from the surroundings, and information relating to the condition of components such as the position of the observation device on the vehicle are provided and communication means, means for initiating functions, and a digital command computer including a processor (21) and a main memory (22) are provided, said system being characterized in that the command computer comprises a graphics processor (23), video electronics (24), a bulk storage interface (25) with a bulk storage (26), and an interactive video screen (30) through which all of the sensed, stored outputted information in the form of digital data relating to the control, the condition and the operational situation of the vehicle is visualized.

Abstract: A test support including an undercarriage and an opening formed therein which is dimensioned for a turret or the like comprises a combat space container interchangeably accommodated in said opening. The combat space container comprises a cage which is detachably joined to said undercarriage, and a roof which is detachably joined to the cage. The cage carries largely invariant components and/or equipment, while the roof carries components and/or equipment which is to be varied more frequently.

Abstract: A torsional spring to be secured non-rotating to mutually rotating components at each end. At least two thin-walled piping sections are positioned loosely coaxial and secured together non-rotating at one end, accordingly functioning as a series of resilient sections. There are means of securing them non-rotating to the mutually rotating components at the other end. The spring especially constitutes a torsion bar for a connecting rod that pivots in a bearing mounted stationary in a vehicle and positions either a running wheel or a caterpillar cogwheel at the end remote from the bearing. The piping sections are integrated into each other such that one merges directly into the other at the end where they are secured together non-rotating in a turnback that represents a transition point. The piping sections are preferably made of fiber-reinforced plastic and may have several layers.

Abstract: An anchoring element for the securing of heavy plates or the like on an anchoring base, particularly for securing armoring elements or additional armoring to vehicles, includes a plate-shaped buffer body of a material that is elastically deformable to a limited extent, such as of rubber or a similar material, and two connecting elements which are rigidly connected with the buffer body and are held by the buffer body at a predetermined distance from one another. Of the connecting elements, which are movable with respect to one another within limits determined by the deformability of the buffer body, one is connectable with the plate to be mounted and the other with the anchoring base. Each of the connecting elements includes a floor metal sheet plate which has a thickness which is very small relative to its other dimensions. The floor metal sheet plates accommodate the buffer body between themselves and are connected with the latter over relatively large areas at the respective contact planes.

Abstract: A method of and a device for safeguarding a vehicle or machinery movable in space, such as a robot, a stacker, an operatorless transporting vehicle or the like against collision, in which by the use of distance sensors, especially ultrasonic sensors with echo time measurement, the distance from an obstacle is measured and a reaction signal is initiated when a preset threshold value is not reached, said method and device being characterized by a time-synchronous actuation of the distance sensors in a compound circuit which in case of a dangerous approach of the vehicle to an obstacle triggers a reaction signal which is either a speed reduction signal or a stop signal. Moreover, the measuring signal can be utilized as a command signal for actively influencing the vehicle movement, e.g. for driving around the obstacle or the like.

Abstract: A method for representing a composite image on a screen of a screen device, the image being composed of a plurality of natural and/or synthetic sub-images generated by diferent sources, is characterized in that the sub-images are composed of a line-by-line representation on the screen by (a) reading out at video rate a pluralaity of pixels, the number of which corresponds to that of the respective sub-image from said storages line by line and (b) repeating step (a) line by line. Furthermore, there is set forth a device for carrying out the method according to the invention.

Abstract: A circuit arrangement for calculating a visual line of sight distance in digitally stored model. A distance long the line of sight is calculated by stepping radially outward along the line of sight. The step sizes which are chosen are selected based on the angle of the line of sight to the grid of the stored model and are selected to ensure that the evaluation points are at points of the grid. The stepping along the line of sight is performed by two sets of integrators and the output of one of the two sets of integrators is selected.

Abstract: In a method of determining the direction of a target by means of an optical square and passing on this direction to a magnifying sight for warfare tanks the exit window (4) of the optical square is provided with a vertical line of sight (8) and the entry window (1) with a sight aid (11). Marked areas (5, 10) in the exit window (4) have the effect that upon adjustment of the sight to the direction defined by the sight aid (11), the marked area positively will lie within the field of view of the magnifying sight.

Abstract: A device for positioning and position stabilizing an inert mass supported for sluing on a base, comprising two driven portions (11,15) adapted to be driven by a motor (1) by way of controllable friction clutches (9,13) is furnished with a single rotor (5) driven by the motor (1) and cooperating with the two friction clutches to transmit a coupling torque in the same sense of rotation. Each driven portion (11,15) acts through separate power transmissions each (16-18,20-23) on the mass, one of the power transmissions effecting a reversal of the direction of rotation.
