Abstract: A method and device for geometrically determining features of a workpiece, having an image processing sensor having a first beam path, the first beam path comprising at least one front optical unit facing the workpiece to be measured, and an optical splitter being mounted on the side of the front optical unit facing away from the workpiece. The optical splitter connects a second beam path to the image processing beam path, a common beam path being formed, and the second beam path being associated with a second optical sensor, the image processing sensor and the second sensor being designed to directly measure the surface of the workpiece. The front optical unit is formed as a sphere and/or has a longitudinal chromatic aberration.

Abstract: The apparatus for performing reconnaissance, intelligence-gathering and surveillance over a zone is of the type comprising means forming a projectile launcher, a projectile (1) equipped with a camera (2) and with an image transmitter circuit (4), and a receiver member for receiving the images transmitted in this way. The launcher-forming means are of a type in which they are individual, manually operated, and portable so that they can be carried by an individual person. The projectile (1) is of small or medium caliber. The receiver member comprises a viewing monitor and a receiver circuit, both of which are small in size so as to form a receiver member that is also individual, and portable. The apparatus can be used and transported by a person on his/her own.

Abstract: Disclosed is a high-acceleration resistant, programmable, electronic time fuze and a method of an apparatus for the correction of the operating time of this time fuze by muzzle velocity measurement carried out inside the projectile or at the gun tube. The time fuze uses the muzzle velocity measured at firing to adjust its operating time. Thus, range dispersion of the event time is substantially reduced. The muzzle velocity is measured with a metal sensitive probe installed inside the projectile. When the probe passes annular grooves in the gun wall, an oscillator is detuned and generates pulses for determination of the projectile muzzle velocity. A bidirectional counter responds to the pulses in one direction, to other information in the other direction and sets off the fuze at a predetermined count such as zero.
