Abstract: A method is provided for a gas turbine engine. During this method, a first lubricant parameter is determined during a first period of an engine operating cycle. The first lubricant parameter is indicative of a first quantity of lubricant within a reservoir of the gas turbine engine. A second lubricant parameter is determined during a second period of the engine operating cycle. The second lubricant parameter is indicative of a second quantity of the lubricant within the reservoir. The first lubricant parameter and the second lubricant parameter are compared to determine a lubricant consumption parameter. The lubricant consumption parameter is indicative of a quantity of the lubricant consumed by the gas turbine engine during the engine operating cycle.

Abstract: In one aspect, the present invention provides a silicon photodetector having a surface layer that is doped with sulfur inclusions with an average concentration in a range of about 0.5 atom percent to about 1.5 atom percent. The surface layer forms a diode junction with an underlying portion of the substrate. A plurality of electrical contacts allow application of a reverse bias voltage to the junction in order to facilitate generation of an electrical signal, e.g., a photocurrent, in response to irradiation of the surface layer. The photodetector exhibits a responsivity greater than about 1 A/W for incident wavelengths in a range of about 250 nm to about 1050 nm, and a responsivity greater than about 0.1 A/W for longer wavelengths, e.g., up to about 3.5 microns.

Abstract: The present invention is a nitrous oxide safety system or method that provides a safety control valve actuated by low-vacuum fluids to control the release of nitrous oxide therethrough. The nitrous oxide safety system may include a low-vacuum fluid, a nitrous oxide fluid, a scavenging mask assembly, and a safety control valve. The low-vacuum fluid is generated by a vacuum source operating to achieve a predetermined parameter and the nitrous oxide fluid is provided by a nitrous oxide source. The scavenging mask assembly is fluidly connected with the nitrous oxide source and the vacuum source. The safety control valve is fluidly connected to the fluid connection between the nitrous oxide source and the vacuum source. The safety control valve is configured to be actuated when the low-vacuum fluid is input to the valve to release a flow of the nitrous oxide fluid through the safety control valve.

Abstract: Techniques disclosed herein describe joining processing elements (e.g., of a streams processing environment) using optimization techniques, such as by whole program optimization. An optimization tool evaluates multiple processing elements based on one or more optimization rules. The optimization tool identifies, based on the evaluation, processing elements that can be merged. The optimization tool joins the identified processing elements together.

The track lighting system includes a housing assembly attached to one or more elongated members for attachment within the operatory environment, one or more ambient lighting assemblies, an intraoral light assembly having a carriage mechanism, an electronic display, and one or more directional task lighting assemblies in a single track lighting system.

Abstract: The present invention is a method and system for administering nitrous oxide. The system includes a fluid control system for controlling the flow of nitrous oxide and oxygen to the patient. A nitrous oxide and oxygen supply, vacuum source, a breather bag, and a nasal delivery interface system are fluidly connected to the fluid control system and a patient. The fluid control system also includes a safety scavenge system including a mass airflow sensor, master controller, nitrous oxide valve, and alarm. The mass airflow sensor reads the scavenging vacuum pressure which it communicates to the master controller. Depending upon the scavenging vacuum pressure, the master controller can activate an alarm or shut off the flow of nitrous oxide. In operation, the present invention provides a system for administering anesthesia/analgesia gas which prevents excessively high volumes of exhaled nitrous oxide in the operatory environment through monitoring of the scavenge vacuum pressure.
