Abstract: A fluid level determining system is for determining a fluid level of a fluid in a reservoir having an interior surface and an opposite, exterior surface. The fluid level determining system includes an emitter configured to be positioned along the exterior surface of the reservoir and emit signals into the reservoir and a receiver configured to be positioned along the exterior surface of the reservoir such that the receiver is oriented in the direction of the emitter. The receiver is configured to receive signals from the emitter passing out of the reservoir. The signals received by the receiver are attenuated relative to the signals emitted by the emitter into the reservoir. A controller is in communication with the receiver and configured to determine the fluid level based on the signals received by the receiver.

Abstract: A flexible array of sensor pairs are used to monitor lubricant condition in an oiler carrying lubricant. The array of sensor pairs are placed adjacent a reservoir and detect the fluid level in the reservoir. The sensor pairs are coupled a chassis and transmit data through communications components which transmit the data to an accessible site for aggregation, monitoring, and alarm features. A recharging system for providing power to the sensors by harvesting light, thermal, or kinetic energy produced by the oiler.

Abstract: This invention provides a spherical lens optical immersion probe for use in analysis of solids, liquids, gases, powders, suspensions, slurries, particles and other homogeneous or heterogeneous samples. The use of a spherical lens in an optical immersion probe confers many advantages over traditional immersion probes including ease of use and accuracy of focus. The probe of this invention has applications to many types of optical spectroscopy methods including ultraviolet/visible (UV-Vis), near-infrared (NIR), mid-infrared (FTIR), fluorescence, and Raman spectroscopy. The spherical lens used in this invention is both the optical and sample interface in the analytical system, and may be used to both focus the excitation source and to collecting signal. Importantly, this invention has broad applications to any optical analytical technology that necessitates an optical immersion probe.

Abstract: An embodiment of the present invention comprises processing a beta titanium alloy by a method including the steps of cold working the alloy and then direct aging the alloy for a total aging time of less than 4 hours. Any beta titanium alloy may be used in the method, for example, Ti-38-644 alloy. The method may include fabricating the alloy into an article of manufacture such as, for example, a bar, wire, a coil spring. The method may be utilized to produce articles with high tensile strength while retain ductility.
