Abstract: At the simulation of a visual field of view as it is used on battle trainers, the image (16) of a background and the image (18) of a moveable target is displayed on a TV-monitor in the field of view of the optics of a person to be trained. The images are digitally stored whereat each image point according to its gray value (G.sub.H, G.sub.Z) is digitally coded. Additionally, with respect to individual objects (forest, bush etc.) in the background each image point is provided with a digital encoded range information (E.sub.H). By comparing this range information (E.sub.H) with the range information (E.sub.Z) of the target it is possible to decide with respect to the image area in which the target is present (G.sub.Z >0) whether the target is to display in front of or behind the individual object (FIG. 2).

Abstract: A pot-core transformer with a magnetic shunt variable to add the function of a variable series inductor independent of the transformer.

Abstract: The method of determining which of several simulator probes in an automated training installation is engaging one of several simulator terminals, which method comprises energizing the terminals electrically and observing the probes individually to determine which has been electrically energized by engagement with a terminal.

Abstract: In combination: an elongated container comprising a plurality of explosively separable parts extending rearwardly from a closed forward end; a load in the rearward end of said container; and a frangible, unitary ballast member in the container between the closed end and the load.

Abstract: Stereo television apparatus comprising, in combination: a projection television receiver for projecting light toward a screen as a sequence of images representative of a video signal comprising left and right video frames alternating at a predetermined frequency; apparatus dividing the light into first and second portions and directing the portions to fall successively on substantially the same area of the screen; and apparatus alternately rotating the planes of polarization of the portions in first and second opposite senses in synchronism with the predetermined frequency, so that when the screen is observed binocularly through eyepieces of oppositely rotated polarization, a stereo image is perceived by the observer.

Abstract: An actuating mechanism comprises a lower housing portion and an upper housing portion. The lower housing portion is cup-shaped and receives a mounting plate into which a thermostatically working element together with a heating coil are inserted. The lower housing portion comprises leaves which are shielded by an insulating plate. Apertures in the insulating plate allow penetration of a working piston of the working element and of contact pins through the mounting plate during assembly of the housing portions whereat the contact pins engage the contact leaves so that the heating coil is supplied with a voltage only in the assembled condition of the actuating mechanism. A compression spring seves as an abutment for the mounting plate.

Abstract: An accelerometer comprising a member of silicon subjected to physical changes in response to the linear accelerations, elements integrated into the surface of the member for generating, amplifying and supplying an output determined by those changes, and means responsive to said output for overcoming said physical changes.

Abstract: In combination: an explosive propulsion member having an axial percussion primer; an electric primer mounted to discharge toward the percussion primer along the axis; and apparatus between the primers hydrodynamically responsive to discharge of the electric primer to percussively engage the percussion primer.

Abstract: In combination: a frame; an outer gimbal mounted in the frame for pivotal movement about a first axis; an inner gimbal mounted in the outer gimbal for pivotal movement about a second axis orthogonal to the first axis; a sensor having a longitudinal axis; apparatus mounting said sensor in the inner gimbal with the longitudinal axis orthogonal to said second axis; apparatus carried by the frame for causing rotation of the outer gimbal about the first axis; and apparatus carried in part by said frame and in part by said inner gimbal for causing rotation of the inner gimbal about the second axis.
