Abstract: A closed loop adaptive fluid control system and method for use in hydraulic applications monitors one or more fluid characteristics, such as pressure, flow rate, accumulation time in an actuator, fill volume, etc., and compares the characteristic with a target response. A fluid characteristic sensor detects at least one fluid characteristic at a hydraulically-actuated device that is actuated by a electrically-operated. The sensor sends a device signal corresponding to the actual sensed characteristic to an electronic controller, which compares the device signal with a target response. The controller then identifies any differences between the device signal and the target response and provides a feedback signal to the electrically-operated valve to adjust the current to the valve, which in turn adjusts the electrically-operated valve so that the device signal corresponding to the sensed characteristic at the device converges toward the target response.

Abstract: A water reservoir is provided for a refrigerator. The reservoir is formed as an elongated tubular member bent into a single U-shape with the tubular member having a constant cross section along its length and a constant vertical rise along its length from an inlet to an outlet. The two legs angle upwardly at a common slope and the legs are substantially the same length so that the inlet and outlet are adjacent to one another. The reservoir thus forms a compact shape which fits into a previously unused space behind a crisper drawer within the refrigerator compartment.
