Abstract: A gas concentration sensor is includes an integrated die-form electromagnetic radiation source and an integrated die-form infrared detector. In one or more implementations, the gas concentration sensor includes a package substrate defining at least one aperture, a gas permeable mesh coupled to the package substrate and covering at least a portion of the at least one aperture, a die-form electromagnetic radiation source positioned in an interior region of the package substrate, a die-form detector positioned in the interior region of the package substrate, and control circuitry operably coupled to the die-form detector and configured to detect and calibrate one or more signal outputs from the die-form detector to determine a gas concentration within the interior region of the package substrate. The gas concentration sensor can be configured for specific detection of various gases through control of the spectral wavelengths emitted by the electromagnetic radiation source(s) and/or detected by the detector(s).

Abstract: Biomarkers of high blood pressure are measured to identify high blood pressure of the subject based on one or more biomarkers. In many embodiments, the response of the biomarker to blood pressure occurs over the course of at least an hour, such that the high blood pressure identification is based on a cumulative effect of physiology of the subject over a period of time. The methods and apparatus of identifying high blood pressure with biomarkers have the advantage of providing improved treatment of the subject, as the identified biomarker can be related to an effect of the high blood pressure on the subject, such as a biomarker corresponding to central blood pressure. The sample can be subjected to increases in one or more of pressure or temperatures, and changes in the blood sample measured over time.

Abstract: A breath analysis system that includes a handle assembly with an analysis cartridge on an upper end thereof. The handle includes a main body portion with a pressure opening and a pressure transducer therein. The analysis cartridge includes a main body portion with an upper portion that defines a breath chamber, a lower portion that defines a fluid chamber and a filter assembly that is movable between a breath capture position and an analysis position. The filter assembly has an opening defined therethrough. In the breath capture position, the opening partially defines the breath chamber and in the analysis position the opening partially defines the fluid chamber. The system also includes an analysis device with a case, a door, a controller that controls the motor and a fluorescence detection assembly and a rotation assembly positioned in the case interior. The rotation assembly includes a shroud with a funnel portion for receiving the analysis cartridge.

Abstract: A shutter assembly includes a first shutter blade having a first toothed arm extending therefrom and a first light transmitting aperture therein, and a second shutter blade positioned adjacent and parallel to the first shutter blade. The second shutter blade has a second toothed arm extending therefrom and a second light transmitting aperture therein. The first and second shutter blades are supported to allow parallel linear motion. A motor gear is disposed between, and meshed with, the first and second toothed arms such that rotation of the gear causes the first and second shutter blades to move linearly in opposite directions between an open position in which the first and second light transmitting apertures are in an overlapping relationship with respect to one another, and a closed position in which the first and second light transmitting apertures are in a non-overlapping relationship with respect to one another.

Abstract: A spatial filter is made by forming a structure comprising a focusing element and an opaque surface, the opaque surface being disposed remotely from the focusing element in substantially the same plane as a focal plane of the focusing element; and by forming a pinhole in the opaque surface at or adjacent to a focal point of the focusing element by transmitting a substantially collimated laser beam through the focusing element so that a point optimally corresponding to the focal point is identified on the opaque surface and imperfection of the focusing element, if any, is reflected on the shape and position of the pinhole so formed.

Abstract: Methods and systems for detecting at least one chemical species including obtaining a first image from a first electromagnetic radiation detector and obtaining a second image from a second electromagnetic radiation detector. The first image includes a first plurality of pixels and the second image includes a second plurality of pixels, each pixel having an associated intensity value. A first resultant image is generated. The first resultant image includes a plurality of resultant pixels, each pixel having an associated intensity value. One or more regions of interest are determined. The correlation between the first image, the second image, and the first resultant image is determined for the one or more regions of interest using a correlation coefficient algorithm to calculate a first correlation coefficient and a second correlation coefficient. The presence of the chemical species is determined based, at least in part, on the first correlation coefficient and the second correlation coefficient.
