Abstract: A method is directed to controlling an electric caliper brake system. The method provides for receiving an ignition voltage signal, receiving a caliper position signal, sending a motor shut down signal, sending a back drive control signal based on the received ignition voltage signal and the caliper position signal, and releasing stored energy from a non-linear device to a caliper brake system motor responsive to the back drive control signal. The non-linear device may be implemented as a capacitor. The step of sending a back drive control signal based on the received ignition voltage and the capacitor position signal includes analyzing the ignition voltage signal for an ignition voltage failure, analyzing the caliper position signal for caliper engagement, and transmitting the back drive control signal responsive to the ignition voltage failure and caliper engagement. Ignition voltage failure occurs when the ignition voltage signal is a low value.

Abstract: A flow control system and a valve for controlling a fluid flow in a flexible conduit. The valve includes a movable member movable to compressingly contact the outer surface of the flexible conduit to adjust the flow cross-sectional area of the flexible conduit. The flow control system includes the flexible conduit, the valve, and a controller. The controller is operatively connected to the movable member for controllably moving the movable member.

Abstract: A torque sensing apparatus for use with a brake caliper having opposing brake pads positioned on opposite sides of a rotor. The brake caliper causes the brake pads to apply a braking force against the rotor that generates a braking torque. A torque transfer device is supported by the brake caliper and is in contact with one of the brake pads. The torque transfer device is resiliently movable with respect to the brake caliper in response to the braking torque. A torque sensor is positioned in a sensing relationship relative to the torque transfer device. Thus, the torque sensor provides an output signal related to a change of position of the torque transfer device and the braking torque. The torque sensor includes a magnet mounted on the torque transfer device and a magnet field sensor, for example, a Hall Effect sensor, is mounted on the brake caliper.

Abstract: A motor reversing control circuit for a motor vehicle windshield wiper has a motor driven cam with a first lobe defining a park position for the wiper and a second lobe defining, in relation to the first, a wipe angle. A park switch is actuated by either lobe to reverse the output of a flip-flop which controls motor direction. The motor is activated in response to one or more of (a) a main switch, (b) the unactuated park switch and (c) the flip-flop output signalling wiper movement toward the park position. An optional timer effective to delay the motor activation in response to the main switch provides a pause in the park position.
