    摘要： An improved variable speed fan controller for use in devices such as laser printers. The controller automatically adjusts its output signal to fans such that a fan quickly settles into an appropriate operating speed, even if the fan has been newly installed into the equipment. The controller can store values in non-volatile memory, if desired, to keep track of recent changes in the fan's operating parameters and corresponding control signal values. The controller is able to control relatively inexpensive fans that don't necessarily operate at a predictable fan rotating speed under repeatable conditions and control signals, by controlling the fan to an initial or predetermined rotating speed; if the fan isn't running within a suitable range of rotational speeds, then determining whether a fine or coarse adjustment should be made to the fan's rotational speed. The controller makes appropriate adjustments until the fan's rotational speed is within acceptable operating tolerances.

    摘要： Described herein are engineered multilayered vascular tubes comprising at least one layer of differentiated adult fibroblasts, at least one layer of differentiated adult smooth muscle cells, wherein any layer further comprises differentiated adult endothelial cells, wherein said tubes have the following features: (a) a ratio of endothelial cells to smooth muscle cells of about 1:99 to about 45:55; (b) the tube is compliant; (c) the internal diameter of the tube is about 6 mm or smaller; (d) the length of the tube is up to about 30 cm; and (e) the thickness of the tube is substantially uniform along a region of the tube; provided that the engineered multilayered vascular tube is free of any pre-formed scaffold. Also described herein are methods of forming said tubes and uses for said tubes including methods for treating patients, comprising providing such a tube into to a patient in need thereof.
