Sapphire Windows

Edmund Optics® (EO) (Barrington, NJ) recently introduced its new TECHSPEC® Precision Sapphire Windows. These windows are ideal for use in a wide variety of demanding applications, including imaging and spectroscopy, as they offer superior broadband transmission from 0.15-5.5 mm. With excellent transmission from the UV to the MWIR, TECHSPEC Precision Sapphire Windows also provide ¼λ surface accuracy. They utilize a high tolerance design and take advantage of the innate characteristics of sapphire - a high dielectric constant, high thermal conductivity, extreme surface hardness and resistance to many chemical acids and alkali, which maximizes system performance. TECHSPEC Precision Sapphire Windows are available in four uncoated sizes -- 10 mm, 15 mm, 20 mm and 25 mm diameters.

9 questions to ask when specifying a slewing ring bearing

In applications where a bearing must support a rotating structure (e.g. cranes, radar, tank turrets), premature failure can put people and equipment at risk. Designers choosing a slewing ring bearing for such applications should consider many factors, such as the bearing’s support structure, mounting (including bolt strength, tensioning and hole patterns), installation, and even storage. A new white paper from Kaydon Bearings, an SKF Group company, details nine key questions to ask when specifying a slewing ring bearing.

Industrial Computed Tomography Inspects Parts in 3D

This nondestructive testing method can quickly inspect parts in 3D while maintaining very high accuracy. Jesse Garant & Associates Inc., Windsor, Ontario, Canada Avery important stage in the manufacturing and production cycle of a part is designing and verifying a prototype. Very often in the medical, automotive, or aerospace industries, very expensive and valuable parts are cut open to locate internal failures or to retrieve internal measurements. Such parts are left destroyed and can no longer be functional after the testing process.

System Health Monitoring Software Learns System Behavior from Data

The new techniques provide faster response and require less computer memory. Ames Research Center, Moffett Field, California The Inductive Monitoring System (IMS) software tool uses data mining techniques to automatically characterize nominal system operation by analyzing archived system data. These nominal characterizations are then used to perform near-real-time system health monitoring or to analyze archived system data to detect anomalies in system behavior as compared with previous nominal behavior.

Detecting High Stress in Oral Interviews and Text Documents

Content of an interview or text is subjected to various levels of statistical analysis to determine if the person knows the truth and is communicating it. Ames Research Center, Moffett Field, California When a person is interviewed, some of the answers may be inaccurate, or even deceptive, because the person may have either incomplete information, is telling only part of the truth, or is fabricating a false answer, or a combination of all three. When the person is habitually making statements that are known to be false, or only partly true, emotional and/or intellectual conflicts often arise within them, and these conflicts may become manifest by inconsistencies in use of different parts of speech or in logical relationships between statements. These inconsistencies are more subtle than inconsistencies in factual statements, and identification of these inconsistencies is more difficult and less straightforward than identification of factual inconsistencies.

Titan Lake and Shore Sampler

The device is suitable for cryogenic dispensing of fluids, and for cryocoolers. NASA’s Jet Propulsion Laboratory, Pasadena, California A lake and shore sampling and sample distribution system was developed for a Titan lake environment (93.7 K, in liquid hydrocarbons). The Titan Lake and Shore Sampler (TLASS) would enable the chemical analysis of hydrocarbon lake samples via a Dual Rectilinear Ion and Orbitrap Mass Spectrometer and Nuclear Magnetic Resonance (NMR) Spectrometry.
