A cruise management method and device for a road vehicle (1), wherein the position of an accelerator control (11) is detected, a current speed (CS) of the vehicle (1) is detected and a current transmission ratio is detected; a desired speed (DS) is calculated as a function of the position of the accelerator control (11), the current speed (CS) of the vehicle (1) and the current transmission ratio and is used to control the drive torque generated by an engine (3) of the vehicle (1) and is displayed by a specific display instrument (16) disposed in a dashboard (13) of the vehicle (1).

A switching device for detecting a voltage interruption at a control unit in a motor vehicle, with a nonvolatile memory for storage of calibration data for an actuator that can be adjusted by the control unit and a drive unit. The control unit is supplied with an internal voltage through a voltage regulator and a bistable multivibrator is connected ahead of the voltage regulator in the external voltage supply of the control unit, and, whereby a microcomputer is connected with the multivibrator and is integrated in the control unit.

This invention provides a push-button switch capable of having an excellent operation feeling, while being thinned. The push-button switch comprises a housing 1 with a housing part 1a, fixed contacts 2, 3 arranged on inside bottom surface of the housing part 1a, a moving contact 4 arranged on the fixed contacts 2, 3, an operation member 6 having a press part 6d projecting from a side part of the housing 1, and an operation part 6c, and a cover body 7 mounted on upper surface of the housing 1, and having an inclined piece 7e cut and raised inside the housing part 1a. Pressing operation of the press part 6d causes the operation part 6c to slide on the inclined piece 7e to bend downwardly to press the moving contact 4. A deformation prevention part is formed to prevent the cover body 7 having the inclined piece 7e from inflating in a direction opposite to the moving contact 4 in the housing part 1a, during pressing operation of the operation member 6.

A functional unit (104) carries out mod2 addition of MSB of operation data stored in an operation data storage section (101) and input data stored in an input data storage section (102). A functional unit (105) carries out mod2 addition of data created by shifting the operation data by one bit to the MSB side and the coefficient of a generating polynomial stored in a generating polynomial storage section (103). A selection section (106) selects either the shifted data or the result of operation by the functional unit (105) according to the result of the operation by the functional unit (104) and stores the selected one as operation data in the operation data storage section (101). In such a way, CRC operation by DSP is efficiently performed with a little investment.

An rotating door driven so as to be swivelable around a pivot of the rotating door includes a rotary bearing; a connection element having a driver piece configured to receive the pivot of the rotating door, the driver piece being mounted in the rotary bearing; and a drive connectable to the pivot of the rotating door in frictional engagement via the connection element.

The invention relates to a working spot of a winding frame, comprising a creel for rotatably supporting a cross-wound bobbin, a device for rotating the cross-wound bobbin, a thread guide for traversing and a thread take-off device which removes a thread from a spinning cop. According to the invention, the thread take-off device (16) removes the thread (30) from the spinning cop (2) at a take-off speed (Vconst.) which is independent of any deviations caused by the traversing. A thread storage (23) is disposed downstream of the thread take-off device (16), when seen in the direction of threadline, and is adapted to the changing thread requirement caused by the traversing of the thread (30).

The invention discloses a space target inverse synthetic aperture radar imaging parameter design method. The method comprises the following steps: a target running track and zenith-passing time are calculated; imaging center time is set; an azimuth angle, an elevation angle, imaging on and off time and a target slope distance are calculated; a redundant slope distance and an initial transmitting pulse width are set; a PRF is selected; whether Dc exceeds an upper limit is judged; an echo window length and Dr are calculated; whether the Dr exceeds the storage and transmission capability is judged; the echo starting time is calculated; beam pointing is adjusted; antenna gains and echo signal intensity are calculated; MGC is set; and imaging is carried out. The motion characteristics of the to-be-imaged space target and the limitations of the radar system are thoroughly considered, STK software is combined, the problems of insufficient calculation precision of target motion parameters, radar beam pointing and system parameters in the traditional space target inverse synthetic aperture radar imaging parameter design are solved, and through a mode of combining mechanical scanning and electric scanning, the beam pointing needed for space target inverse synthetic aperture radar imaging is realized, and the realization cost and the complexity are reduced.
