摘要： A solenoid closure servo control eliminates impact of the solenoid poles against each other upon closure of the device. A model of the device closure is obtained from a parameter of initial gap. During closure of the device, the rate of closure of the gap of the solenoid and the force in balance between the spring and magnetic force is calculated and compared to the model. Imbalances are corrected by applying a corrective voltage to the solenoid coils.

摘要： A miniature four-wheeled vehicle is provided with a solenoid having a linearly movable armature for turning the steering wheels in response to electrical impulses received by a set of contact brushes on the vehicle which selectively engages the conductive track system on a supporting surface which also supplies power to the vehicle and includes conductive guiding areas on the surface for steering the vehicle through a switch in the track system.
