A shot peening valve controller comprises a hub connector configurable for connecting or operating one or more shot peening valve; a microprocessor that is connected to the hub connector; and a human-machine interface that is connected to the microprocessor. The human-machine interface is configured to operate the one or more shot peening valves respectively.

The present invention provides control methods, control systems, and control software for microfluidic devices that operate by moving discrete micro-droplets through a sequence of determined configurations. Such microfluidic devices are preferably constructed in a hierarchical and modular fashion which is reflected in the preferred structure of the provided methods and systems. In particular, the methods are structured into low-level device component control functions, middle-level actuator control functions, and high-level micro-droplet control functions. Advantageously, a microfluidic device may thereby be instructed to perform an intended reaction or analysis by invoking micro-droplet control function that perform intuitive tasks like measuring, mixing, heating, and so forth. The systems are preferably programmable and capable of accommodating microfluidic devices controlled by low voltages and constructed in standardized configurations. Advantageously, a single control system can thereby control numerous different reactions in numerous different microfluidic devices simply by loading different easily understood micro-droplet programs.

A system for remotely controlling and documenting valve lubrication. The system includes an operator unit programmed to communicate with a remote controller unit that actuates the transfer of lubricant to user-selected valves.

A system and method for measuring an amount of backlash in an actuator assembly that includes a housing assembly, an actuator, a drive source, an actuator position sensor, a drive source position sensor, and a controller. The controller is in operable communication with the drive source, the actuator position sensor, and the drive source position sensor, and is configured to selectively implement a built-in test that determines the amount of backlash in the actuator assembly.

A method for controlling a pump-down operation in a wellbore includes selecting a target value for downhole tension of a support cable and a recommended job speed to convey a wireline tool string down a section of the wellbore, generating a line speed signal for controlling a line speed of the support cable and a pumprate signal to control a pumprate of a hydraulic fluid in the wellbore, determining a first error between the target value for downhole tension and a measured value of the downhole tension, determining a second error between the recommended job speed and an actual line speed, and maintaining the target value for the downhole tension by simultaneously controlling the line speed and the pumprate using a value for the line speed signal and a value for the pumprate signal generated based on the first and second errors.
