Abstract: A Fluid Flow Control System (FFCS) door assembly includes a continuous belt and a plurality of rollers. The plurality of rollers support the continuous belt and define a first segment, a second segment, a third segment, and a fourth segment. The continuous belt includes a plurality of openings that selectively allow fluid flow to pass through the first segment, the second segment, the third segment, and the fourth segment when two openings of the plurality of openings align with the first segment, the second segment, the third segment, or the fourth segment.

Abstract: An actuator assembly for actuating actuatable members. The actuator assembly includes an upper cam mounted to an upper side of a center plate. The upper cam is rotatable by a motor. A lower cam is mounted to a lower side of the center plate. The lower cam is rotatable by the motor. The upper cam and the lower cam are configured to rotate at different speeds and are configured to actuate linkages for moving the actuatable members.

Abstract: A single turn potentiometer sensor has a substrate, a first and a second carbon print. The first carbon print, with a desired width, extends across a large circumferential angle. Ends of the carbon print are connected to a regulated power supply and ground. The second carbon print, with a width smaller than the first carbon print, surrounds a hole in the substrate and is positioned inside the first carbon print. The second carbon print provides a sensor output. A wiper contacts between the first and second carbon prints. A voltage divider changes value based on a wiper position on the first carbon print. One or more pads are positioned on the first carbon print. The one or more pads provides an input voltage to the sensor.
