摘要:
The invention relates to a rotary encoder comprising internal error control with a monitoring unit comprising at least a computing module, a verification means, a memory unit and an alarm unit. The invention also relates to a method for checking a rotary encoder when said encoder is in operation, the rotary encoder generating at least one measuring signal pair representative of the amount of rotation. In order to be able to determine the functioning of the rotary encoder, even when said rotary encoder is stationary, it is provided according to the present invention that a characteristic value should be created in the monitoring unit from current amplitude values of the measuring signal pair, said characteristic value being used in a comparison with at least one quality value representative of the functional states of the rotary encoder.

An incremental transducer (1) as well as a process (D1) are provided for determining an actual position of a body (5) along a measuring path (W) and/or a change therein. A position code (7) of the incremental transducer (1) has a gap (10). To make it possible to use the incremental transducer (1) as flexibly as possible and to operate it despite dimensional tolerances of the body (5), provisions are made for converting an actual location frequency (Fi) of the position code (7) into a desired location frequency (Fs) that is independent from the length (L) of the gap (10) to generate a position signal (S) representative of the actual position or the change therein.

摘要:
The present invention relates generally to a weapon having an eccentrically-pivoted barrel (1) that is mounted on a movable base (2), and to a method of elevating and stabilizing such a barrel. A drive mechanism (3) acts between the barrel and the base to permit and enable the elevation of the barrel relative to the base to be selectively changed. A compensation device acts between the barrel and base to compensate for the unbalance of the barrel. The compensation device includes a gyroscope (13) mounted on the barrel and arranged to provide an output signal, a set point generator (12), a closed-loop control device (10) and an actuating element (16). The actual position of the barrel is sensed by the gyroscope, which supplies its output signal to the set point generator. The set point generator produces a set force value as a function of the gyroscope output signal. The set force value is supplied to the closed-loop control device, which produces a set point value that is, in turn, supplied to the actuator for controllably changing the elevation of the barrel.
