An animal deterrent device includes an elongated carrier having a conductive trace. The commanded torque is adjusted as a function of a phase lag between the commanded torque and an actual torque which the motor would deliver in response to the commanded torque such that in response to the adjusted commanded torque the motor delivers the actual torque which counteracts the oscillations. The floating metal structure may be anchored into the base layer. The image related data generator sends specification data that specifies image processing control data to be updated to an update data server. Most advantageously, a drive mechanism is provided for driving the double seaming chuck and the double seaming roll at respective speeds that are selected so as to reduce relative rotational speed between the double seaming roll and a workpiece when the double seaming roll comes into contact with the workpiece during the double seaming operation.
