Abstract
In this invention an all electronic circuit for moving and stopping an object is disclosed. The object is responsive to movement from a drive signal. The object is moved from a first position to a final position and is stopped without physical damping or substantial ringing and the like. The circuit provides for the generation of a first signal which moves the object from the first position to an intermediate position, which is between the first position and the final position. A second signal is generated where the second signal is a time delay signal of the first signal. The first and second signals are combined to produce the drive signal.
Claims5
An electronic circuit for moving and stopping an object, responsive to a drive signal, from a first position to a final position, without physical damping or substantial ringing and the like, said circuit comprising:
- means for generating a first signal for moving said object monotonically and continuously from said first position to an intermediate position, approximately one-half the distance between said first position and said final position, said object having a resonant frequency in response to said first signal;
- and
- means for generating a second signal wherein said second signal is a time delay of said first signal by greater than or equal to one-half the rate of said resonant frequency, for moving said object monotonically and continuously from said intermediate position to said final position
- wherein said first signal and said second signals are the components of said drive signal.
A method of moving and stopping an object from a first position to a final position without physical damping or substantial ringing and the like, said method comprising:
- (a) applying a force to move said object monotonically and continuously from said first position to an intermediate position;
- approximately one-half the distance between said first position and said final position;
- (b) waiting for a predetermined period of time greater than or equal to one-half the rate of the resonant frequency of the object;
- and
- (c) applying said force to move said object monotonically and continuously from said intermediate position to said final position.
