Abstract: A control unit for generating a control signal comprises a base part, a control element rotatable about an axis of rotation relative to the base part, a position encoder for detecting an angular position or a change in angular position of the control element relative to the base part, a control device which is adapted generate the control signal in dependence on the detected angular position or change in angular position of the control element and an electronic display device, wherein the control device is adapted to control the electronic display device to show at least one symbol arrangement. The control unit is characterized in that the electronic display device has the shape of a cylinder or of a cylinder sector whose axis coincides with the axis of rotation of the control element or extends in parallel thereto.

Abstract: An image sensor, in particular a CMOS image sensor, for electronic cameras includes a plurality of light-sensitive pixels arranged in rows and columns for generating exposure-dependent pixel signals. A plurality of column lines, at least one precharge circuit for charging or discharging the column lines and at least one column readout circuit for reading out the pixel signals of the respective column are associated with a respective column. The image sensor has at least one switching device which is adapted to couple, in a first switch state, one of the column lines of a respective column to the precharge circuit and another one of the column lines of the respective column to the column readout circuit.

Abstract: A command fuzing system for use in conjunction with small, rapid-fire protiles. A narrow-beam radar transmitter, mounted on the weapon, transmits radar pulses along the trajectory of the projectiles. Each projectile contains a small horn antenna, a detector responsive to the radar pulses, an amplifier and a counter which is advanced with the receipt of each pulse. Upon receipt of a predetermined number of pulses, the counter triggers an SCR switch to cause detonation of the projectile in a well known manner. By adjusting the pulse rate of the radar transmitter the operator of the weapon can control the number of pulses reaching each projectile in a given time period, thereby controlling the point along the trajectory at which detonation occurs.
