Abstract: A valve assembly monitoring system receives operational data that is representative of one or more parameters of a valve assembly's operation and that is collected by the valve assembly during normal operation. The valve assembly monitoring system is configured to identify, based on the operational data, a change in valve travel setpoint that indicates a start of a valve transition and a subsequent change in valve travel that indicates an end of the valve transition. Based on the identified start and end of the valve transition, the valve assembly monitoring system is configured to generate a valve transition time and to compare the generated transition time to transition time limits of the valve assembly to alert maintenance personnel to problematic increases in transition time.

Abstract: A compressor includes: a casing with an inner wall defining a compression chamber, an inlet leading into the compression chamber, and an outlet leading out of the compression chamber; a rotor rotatably coupled to the casing for rotation relative to the casing; and a gate coupled to the casing for movement relative to the casing. The gate may be pivotally, or translationally coupled to the casing. A hydrostatic bearing may be disposed between the gate and casing. A plurality of compressors may be mechanically linked together such that their compression cycles are out of phase.

Abstract: A themed holograph theater system and method for presenting interactive holographic imagery that presents 2D or 3D holographic imagery interactive with physical objects. The themed holographic theater system includes a camera or scanner to obtain data concerning the physical object, a projector to project images on a holographic media and a program to identify the physical object based on the camera or scanner data and control the projection of images interacting with the physical object.
