Abstract: An apparatus includes a housing and a chamber. The chamber is configured to hold analyte. The chamber includes a reflective element, either a reflective coated layer or a reflective mirror, to return optical signals entering the analyte. A window is coated with an anti-reflective material or has negligible optical interference. A cap seals the chamber and the housing. A flow channel is provided within the housing and the chamber assembly to allow the analyte to flow through with reduced bubble entrapment as the cap is tightened to seal the chamber assembly.

Abstract: A performance-monitoring system is configured to determine whether a diminished performance of a computing system warrants prompt remedial action by generating a score indicative of various aspects of the computing system. In some examples, the performance-monitoring system identifies a change to a computing system comprising at least one server running two or more applications; runs one or more diagnostic tests on each of the two or more applications to collect additional performance data; determines, based on the additional performance data, a relative performance score for each of the two or more applications, wherein the relative performance score for a respective application indicates at least an effect of the change on an ability of a user to use the respective application to perform one or more user operations; determines that the performance score is less than a threshold score; and automatically reduces a rate of transaction requests sent to the server.

Abstract: An optical window for an imaging system such as a Raman spectrometer, NIR spectrometer, fluorometer, or hyperspectral camera is configured to contact the subject. It includes: a substrate; and a flexible medium, where the flexible medium is configured to be deformed with substantially the same profile as that of the outer surface of the subject. The refractive index of the flexible medium and substrate is selected such that light collection efficiency and/or imaging quality returned to the measurement system increases after application of the optical window.
