摘要： A rocking seat control apparatus for a moveable seat supported and having a magnetic member attached thereto is provided that is capable of maintaining the seat being rocked constant in rocking amplitude. The apparatus includes a solenoid for bi-directionally attracting the magnetic member to cause the seat to move in a positive and a negative direction alternately and thereby to be rocked; an amplitude measuring means for measuring an amplitude of the seat being rocked and a rocking motion of the seat; an amplitude damping factor measuring means responsive to displacements in the positive and negative directions of the seat being rocked for measuring an extent of damping factor of the amplitude caused while the seat is being rocked; and a solenoid energizing means for energizing the solenoid means during a time period in which the seat is being rock traveling a distance that is a product of the measured rocking swing and the measured extent of damping factor of amplitude. A rocking seat control apparatus is also provided that includes a rocking control circuit that computes a 1/f-type fluctuating rocking motion for driving the solenoid so as to rock the seat in a mode of 1/f-type spectrum fluctuation.

摘要： A device for controlling the amplitude of a swinging body. The device accurately controls the drive thereof in response to the load the swinging body carries even if it carries infants of different weights. A desired swing is provided by a sensor portion which generates first and second pulse signals having different phases in response to the swing and a control circuit which obtains sensor data based on the first pulse signal and the second pulse signal, decodes data patterns set in advance which corresponds to a combination of the sensor data, judges a swing direction or a change thereof from a changed pattern of the continuous data patted, reads a target value (pulse count number) set in advance to compare or the like with the pulse count number of the present, the previous, and the one before the previous to obtain a pulse width for driving at the next timing, and outputs a drive pulse of the obtained pulse width to a drive circuit so that driving can be performed in accordance with the expected value of the swing set in advance.
