A controlled motion system having a plurality of movers controlled as they travel along both smart and simple sections of a track. The controlled motion system comprises a control system for controlling the speed of a mover as it travels along a simple section, and permits the pitch or distance between movers to increase or decrease as they travel along a simple section. In a preferred embodiment the controlled motion system includes at least one coupling feature having a driving feature on a simple section for engaging and operably driving a driven feature on each mover such that positive control of each mover is maintained throughout its transition from a smart section to a simple section.

The present disclosure simplifies the H-bridge circuit of the direct current motor for driving the damper (door) that switches the air passages in the indoor unit of an air conditioning device. The control device for an air conditioner that takes in inside or outside air and conditions the air inside an air conditioning unit using an evaporator and a heater core is provided with: a first actuator and a second actuator that drive the multiple dampers installed inside the air conditioning unit for switching the air passages; and three half-bridge circuits that control the first actuator and the second actuator sharing one of the half-bridge circuits. Of the multiple dampers, the first actuator is connected to the inside/outside air switching damper. Of the multiple dampers, the second actuator is connected to at least one air mix damper.

A dynamic linear motor is controlled by determining a relative proximity of a moving rotor of the linear motor to a fixed stator segment of the linear motor using a current location of the moving rotor. A current driving characteristic of the linear motor at the current location of the moving rotor is determined. Settings for the fixed stator segment when the moving rotor reaches the fixed stator segment are identified based on the current driving characteristic. The fixed stator segment is driven based on the settings when the moving rotor reaches the fixed stator segment.

An ultrasonic electro-mechanical resonant system and instrument that provides improvements in the design and implementation of a feedback system. The disclosed configuration and orientation of coils enhance the motional or velocity feedback signals while minimizing the effects of transformer coupling. A two coil and a three coil approach is disclosed that takes advantage of non-homogeneous magnetic fields. An asymmetrical arrangement enables velocity signals to be coupled into the coils without requiring additional signal conditioning or capacitive elements.
