摘要： An attitude control apparatus for a satellite includes: at least three electric motors, wherein the at least three electric motors are arranged in such a way that a torque may be generated with any orientation of an associated torque vector, and a controller, wherein the controller is configured to drive the at least three electric motors based on a torque controller. The torque controller is adapted to operate the at least three electric motors outside a rest state only when an acceleration torque and a braking torque are required to execute an agile attitude change maneuver. There is also described an associated method.

摘要： The invention relates to a method for the computer-controlled display of speed information, which represents the movement speed of a real moving object relative to the surroundings of the object, using an image display device. The speed information is displayed by generating one or more visually perceptible moving graphical patterns using the image display device, wherein the movement speed of the real moving object is reproduced by the one or more graphical patterns in a qualitative manner. The invention further relates to a device for the computer-controlled display of speed information, to a flying object with such a device, and to a computer program for this purpose.

摘要： An image sensor comprising a row of light sensors registering incident light as electric signals, and a shift register including first and second register places per each light sensor is used for recording frames in fast succession. The image sensor allows for transferring the electric signals from the light sensors to the respective first register places and for shifting the electric signals on selected ones of the first and second register places forward in the shift register. After a first exposure time, the electric signals from each of a plurality of pairs of neighboring light sensors are added on one register place. After a second exposure time, the electric signals from each of the same pairs of neighboring light sensors are added on one register place located between two of the register places on which added electric signals from the first exposure time are present.
