In a method for determining the elongation of segments of a chain of a chain drive during operation, a plurality of measured values is determined at different positions of the chain. A plurality of length values is determined from the plurality of measured values and the length values are assigned to the segments of the chain, with the length of the segments of the chain being smaller than the length of the chain.

A displacement sensing method of the present invention includes the steps of superimposing a predetermined signal on a torque command to supply a drive torque to a motor, measuring an amplitude spectrum ratio between the drive torque in superimposing the predetermined signal on the torque command and a motor angle measured by a displacement sensor, generating correction data for evening out the amplitude spectrum ratio, and correcting the measured motor angle so that the motor angle measured by the displacement sensor is equal to an actual motor angle using the correction data.

A computer system may determine a target position of the electronic component. The computer system may also determine a current position of the electronic component. The computer system may compare the current position to the target to position to determine whether the electronic component is in the target position. If the electronic component is not in the target position, the computer system may use an electroactive polymer to adjust the position of the electronic component to move the electronic component into the target position.
