In an image processing system, a subject object 210 is placed on top of an object support 220 on a calibration object 34 having a known pattern of features thereon. In one embodiment, the antenna unit includes at least one remote antenna circuit having one or more ports to receive a control signal and a transmit signal transmitted from the WAP located in a multi-tone transmitter-receiver. Two molds alternately move in respective first and second radial directions from the parison receiving position to respective first and second outer positions, to a common article take-out position and then back to the parison receiving position from a third radial direction. A controller receives a signal indicative of rotational motion from the sensor, determines a direction of the rotational motion of the housing, and drives the motor in a direction corresponding to the direction of rotational motion of the housing.
