Abstract: A self-calibrating sensor includes a housing, an input lever coupled to the housing and configured to contact a device to be sensed, and an actuating element configured to automatically reposition an output device to a calibrated position. The sensor also includes a cam ring that is configured to move the output device to the calibrated position based on an input received from the actuating element and a lock ring coupled to the input lever. In one exemplary embodiment, the output device is an electrical contact assembly that is slidably engaged with the cam ring. During operation, the cam ring is configured to reposition the electrical contact assembly based on the input received from actuating element.

Abstract: A peristaltic pump for pumping fluids through a flexible tube has a pump body, a support structure, a tube retaining mechanism and a linkage mechanism. Locating features make sure that the support structure is at a fixed location with respect to the pump body when the pump is in the closed position. The support structure controls movement of the retaining mechanism. The linkage mechanism applies the necessary force to move the support structure so that the pump is moved from an open position to a closed position.
