摘要： A linear voice coil actuator is described, specifically applied to a fluid power valve. The valve includes at least one inlet port and at least one outlet port. A spool controls fluid flow between the inlet port and outlet port. At least one counter-acting spring asserts a force on the spool. The valve also includes a linear voice coil to regulate movement of the spool. The linear voice coil responds to a pulse width modulated signal, wherein the pulse width modulated signal is based on a determined current in the linear voice coil. Electromagnetic interference filtering may also be used. A controller, system and method are also described.

摘要： A calibration engine to eliminate disconnects between both manual and automated calibration procedures. It abstracts the process of procedure development such that procedure writers produce automated procedures without being computer programmers. By organizing calibration procedure elements in a relational database format, a relational automated calibration engine (RACE) provides the mechanism whereby a single calibration procedure is executed in either a manual, automated, or semi-automated fashion. The engine operates both with and without an installed operating system and relational database server. Interfaces ensure interoperability with other laboratory software elements such as scheduling, reporting, and measurement uncertainty.

摘要： A method for sensing and compensating for variances in load and voltage in a closed loop voice coil system (95) is described. A load (55) in a system (95) which included a supply voltage (45) and the load (55), which includes an inductive element, is excited with a known duty cycle for a time interval. At an end time, at the end of the time interval, the current which flows through the load (55) is sensed. A lumped term based at least in part on the time interval and a change in the load current during the time interval is calculated. The lumped term is representative of the supply voltage (45) and one or more electrical characteristic of the load (55). A control signal (25) to control a voltage applied to the load (55) may be generated based at least in part on the lumped term. Apparatus and computer-readable media are also described.

摘要： In accordance with an example embodiment of the present invention, a valve is disclosed. The valve includes a valve body, a seat, a poppet, and a shaped portion. The valve body has an inlet portion and an outlet portion. The seat is between the inlet portion and the outlet portion. The poppet is proximate the seat. The poppet is adapted to modulate fluid flow between the inlet portion and the outlet portion. The shaped portion is downstream of the seat. The shaped portion is adapted to direct fluid flow, reduce cross flow interference, and allow for substantially parallel fluid flow jets at a majority of the inlet portion and the outlet portion when fluid is flowing through the valve.

摘要： A positioning system includes an actuator, valve (preferably pneumatic), position sensor and an electronic valve controller, integrated in a single unit. Continuously variable setpoints are possible within the range of operation. A preferred control circuit includes a signal converter, a ramp generator to smooth the shape of the command or target value signal applied, a position feedback sensor to report the actual position of the actuator, a controller, and a driver, containing an H-bridge, for controlling the pneumatic valve which feeds air into the actuator mechanism. Integration of all these components into a single unit shortens signal paths, improves resistance to electrical noise, and permits faster response time.
