Abstract: A sanitizer system includes a duct like enclosure with roll up doors at an entrance and/or an exit, the system for treating reusable items with one or more of ultraviolent light, an electrostatic fog, an ultra-low capacity spray, and a pressurized solution such as a pressurized water wash.

Abstract: A shock absorber having an elongated pressure tube and a piston slidably mounted in the pressure tube which divides the pressure tube into a first and second working chamber. An elongated piston rod is attached to the piston and moves in unison with the piston in both an extended and a compression direction. Movement of the rod in a compression direction decreases the volume of the first working chamber and increases the volume of the second working chamber, and vice versa. A control orifice and adaptive valve are fluidly connected in series between the first working chamber and a reservoir. A check valve is fluidly connected between the control orifice and the adaptive valve which opens only upon movement of the rod in a compression direction.

Abstract: A shock assembly includes a first tube having a cylindrical wall with an inner surface and an outer surface. A second tube is received within the first tube and includes a cylindrical wall having an inner surface and an outer surface. A piston assembly is received within the second tube and includes a piston rod and a piston that is selectively movable relative to the first tube and the second tube. A height-sensing device is disposed within the first tube between the inner surface of the first tube and the outer surface of the second tube.

Abstract: In order to control the turbine speed of a windmill employed for power generation, the pitch of the turbine blades is based on a dual-deadband control strategy. If the current turbine speed is determined to be outside of a relatively wide deadband, action is taken to correct the speed by changing blade pitch accordingly. If the current speed is not outside of the relatively wide deadband, then the average of the turbine speed over a recent interval is compared with a relatively narrow deadband within the wider deadband. Action is then taken to change the blade pitch if the average speed is outside the narrow deadband. In this way, wide excursions of turbine speed are corrected promptly, but the frequency of control actions is minimized by requiring only the average speed to be kept within tight limits.
