    摘要: A method and apparatus for quickly determining leakage in pressurized fluid receptors. Pressure determinations are made substantially immediately following the completion of the filling of the item to be tested with the pressurized fluid without the need for a stabilization period. The complete decay curve is calculated from the pressure determinations. A time constant is determined from the curves defined when no leakage is present and is utilized in determining the leakage rate whenever the two curves defined by the pressure points provide different end pressure values. The determinations may be made by conventional microprocessor-based instrumentation to provide a substantial increase in the rate of conducting fluid leakage tests.

    摘要: A system and method for increasing resolution of pulse width modulated (PWM) signal duty cycle calculations in a fan speed control system operating to control rotational speed of at least one fan. The method may comprise obtaining a temperature reading from a first temperature sensor in the fan speed control system during a first time period. The temperature reading has resolution of a first number of bits. A portion of the first number of bits is selected for calculating a PWM signal duty cycle with the resolution of the first number of bits in the temperature reading using only the portion of the first number of bits and zone parameters associated with the first temperature sensor. The PWM signal duty cycle may then be converted into a PWM signal that may be provided to the at least one fan.

    摘要: A hand truck for moving sheet material has a laterally extending shelf and a generally upright frame, which extends upwardly from the shelf. The frame may be formed by tubular metal of generally inverted U-shape and together with the frame support a load. The hand truck has a pair of inline primary wheels, mounted on fixed parallel axes, near the two ends of the shelf and the lower ends of the two sides of the frame. The two primary wheels lie in a common plane. A turning wheel, also mounted for rotation about a fixed axis, is situated midway between the two primary wheels but slightly out of line therewith. The turning wheel is of smaller diameter than the two primary wheels, and the plane in which it is mounted forms a small acute angle with the plane of the primary wheels. The turning wheel is out of contact with a supporting surface when both primary wheels touch the supporting surface. For movement of the hand truck in a straight path, both primary wheels touch a supporting surface and the turning wheel is out of contact with the supporting surface. For turning movement, one of the two primary wheels and the turning wheels are in contact with the supporting surface, while the other primary wheel is raised slightly above the supporting surface so as to be out of contact. The turning wheels may be adjustably mounted by a hand or foot operated lever.
