Abstract: A seat reclining and fold-flat mechanism for reclining the seat-back, folding the seat-back flat and locking the seat in an upright or reclined position. The mechanism includes an arm, a pawl and a locking member. The arm is pivoted to the frame at one end and attached to the seat-back at a second opposite end to pivot the seat-back relative to the frame. The pawl is pivoted to the frame and pivots between a locked position, in which the pawl engages the arm to prevent arm from pivoting, and a released position, in which the pawl releases arm allowing arm to pivot. The locking member secures the pawl in the locked position, thereby securing seat-back in an upright or reclined position even when substantial force is executed on the seat-back.

Abstract: An adjustment mechanisms suited for vehicle seats, and particularly mechanisms that include a memory feature. The inventive adjustment system is of the type that provides a method of selecting a preferred seat position, releasing the adjustment mechanism for free movement of the seat, and automatically arresting the adjustment mechanism, securing the seat at the selected position. In the case of some prior art seat adjustment mechanisms, using the recline adjustment control to dump the seat does not allow the passenger to automatically return the seat back to the selected position. Other prior art seat adjustment mechanism separate the recline adjustment and the dump controls but rely upon relatively bulky stamped metal components to capture and latch the seat after dumping.

Abstract: A method and system for determining change in a fluid's flow rate within a line. The pressure variation in a second fluid, separated from the first by a pumping membrane, is measured in response to energy applied in a time-varying manner to the second fluid. From the response of the second fluid to the applied energy, changes in the flow rate of the first fluid are determined.

Abstract: A method is provided for regulating fluid pump pressures by detecting an elevation differential between a fluid flow control device and the distal end of a fluid line in communication with the fluid flow control device. A fluid flow control device, for instance a peritoneal dialysis device, is at a first height, a distal end of a fluid line is at a second height, and a valved outlet, when open, affords communication between the fluid flow control device and the distal end of the fluid line. The elevation differential is correlatable with a pressure measurable during a calibration procedure provided as a part of the methodology.

Abstract: A fold-flat seat recliner mechanism for connecting the seat cushion to the seat back in a motor vehicle includes a lower plate assembly attachable to the seat cushion frame and an upper plate interconnecting the seat back and the lower plate assembly. The upper plate and lower plate assembly are interconnected by a parallelogram linkage that provides a range of reclining positions for the seat back relative to the seat cushion and allows the seat back to be folded flat relative to the seat cushion from any recline angle. During folding, the linkage retains its previous geometry so that the seat back, when unfolded, returns to its previously set recline angle. The mechanism is used in pairs, one on each side of the seat. On one side the recliner mechanism includes a mechanism for adjusting the seat back recline angle and a latch operable to inhibit or allow folding of the seat back.

Abstract: An apparatus, method, and computer program product for detection of fluid leakage through a membrane in a fluid flow control system. The fluid flow control system has a first chamber and a second chamber. A membrane is disposed between the first chamber and the second chamber. The second chamber has a connection to a pressure tank, the pressure tank has a fluid with a pressure, and the connection defines a fluid path. The method indudes in a first step, blocking the fluid path. The pressure of the fluid in the pressure tank is then adjusted. The pressure is measured in the pressure tank which creates a pressure measurement at each of a first set of multiple timed intervals while the fluid path is blocked and after the pressure is adjusted. A blocked pressure rate is calculated based on the pressure measurements in the pressure tank at the first set of multiple timed intervals. Next, the fluid path is unblocked.

Abstract: A method and system for determining when a fluid has stopped flowing within a line. The pressure variation in a second fluid, separated from the first by a pumping membrane, is measured in response to energy applied in a time-varying manner to the second fluid. From the response of the second fluid to the applied energy, it is determined whether the first fluid has stopped flowing.
