Patent number: 8764266
Abstract: A repetitive lighting fixture will alternate between at least two different illuminated images projected in a desired direction. The fixture includes edge-lit flat panels that are configured and/or overlayed to reproduce one or more desired images. Each panel is made of light-transmissive material, which optionally may contain colorant. Each edge-lit flat panel contains optics coupled with a second planar surface of the panel. The optics are arranged to define a desired shape of an image and are configured so as to cause light distributed within the panel to exit a first planar surface of the panel. Each panel has its own light source that projects light into a light transmitting edge of the panel. The panel's light source can include light emitting diodes (LED) that only or selectively illuminate the specific optics of that panel.

A system is also disclosed including a compressor, an on-line wash system coupled to the compressor, and a compressor fouling sensor that senses a compressor fouling level. A source of washing fluid is provided, and a control subsystem that initiates a wash with washing fluid from the source of washing fluid based on a compressor fouling level.

Abstract: Provided is a system for replacing a fluorescent lamp with a light emitting diode (LED) into a conventional fluorescent lighting fixture without modifications. The lighting assembly includes an LED unit having a first end and a second end. The lighting assembly also includes a safety locking device positioned on at least one of the first end and the second end of the LED unit and coupled to a lighting fixture. The safety locking device comprises a safety switch defining an unarmed state and an armed state. To prevent a risk of shock, the safety switch is changed from the unarmed state to the armed state upon manual activation of the safety switch after the LED unit is moved into a locked position. The armed state enables an electrical communication between the two ends of the LED unit to activate the LED unit.

Abstract: Provided is a lighting ballast system and method for fluorescent lamps. The system and method utilize a lamp current control loop to control the light level of a fluorescent lamp. The ballast includes an open loop detector that recognizes an open current control loop as an indication of a fault or hazard condition, and causes the ballast to output a safe lamp voltage or no voltage. The fault or hazard condition may be, for example, a very high voltage at the lamp or very low current across the lamp. The ballast also includes a disable circuit that prevents the open loop detector from triggering at times when the loop is expected to be open such as during ignition and maintenance restarting of the lamp.

Abstract: An x-ray system includes x-ray tube containing a cathode which supplies electrons and an anode which can be maintained at high positive electrical potential to the cathode and has a target area which is impacted by electrons from the cathode when the positive potential is maintained generating x-rays. The x-ray tube is enclosed in a radiation resistant casing. The radiation resistant casing has a window which allows some of the x-rays generated at the target area to exit the system. The window has a vapor deposited layer of a filtering metal of sufficient thickness to effectively condition the x-rays passing through the window and located to intercept the x-rays passing through the window.

Abstract: A pumping system includes a hydraulic motor assembly configured to drive a production pump. The hydraulic motor assembly includes a master pump located on the surface and an electric motor configured to controllably power the master pump. When moved by the electric motor, the master pump discharges a working fluid under pressure. The pressurized working fluid is transferred to a hydraulic turbine located in the wellbore. The hydraulic turbine converts the pressure of the working fluid into torque, which is transferred through a driveline to a production pump. The production pump pressurizes production fluids, which are carried under pressure to the surface.
