Abstract: The present invention relates to a method for compensating timing errors of real-time clocks, which comprises a compensating step, wherein in step 1, assign CNT to be 0 and execute step two; in step 2, assign FLAG to be 1 when a rising edge of 1 Hz clock is arrived and execute step 3; in step 3, judge FLAG and M3, if FLAG=1 and M3<0, execute step 4 while waiting until CNT=S4; if FLAG=1, CNT=0 and M3>0, execute step 5; otherwise execute step 2; in step 4, execute an assignment operation, CNT=0, M3=M3+S4, FLAG=0 and restart step 2; in step 5, execute an assignment operation, CNT=S4, M3=M3?S4, FLAG=0, and restart step 2. A sampling frequency of relative errors ERR of the present invention is adjustable, and a compensatory accuracy is much higher.

Abstract: The invention describes a simulated steering apparatus provided with a base (2), a driving shaft (11) with a first and second ends. A first plate (21) is rigidly mounted to the driving shaft and a second plate (18) is freely mounted to the driving shaft. The first plate is disposed at a close proximity to the second plate. A friction means (19) is disposed between the first plate and the second plate. A motor (34) is operably connected to the second plate. A force exerting means (20), which is disposed in the vicinity of the first and the second plate, holds them together. A position sensing means (40) operably connected to the driving shaft, actuates the motor when the driving shaft is not in a neutral position. The motor is actuated, such that, the second plate rotates in a direction opposite to that of the first plate.
