Abstract:
Disclosed is an infrared optical sensor for the continuous analysis of a liquid flowing in a pipe. The sensor includes, in a housing, a central section of duct through which the liquid to be analyzed flows, and a spectral analysis device using a light beam, including an infrared source which emits a signal which is received by a receiving device having passed through the liquid, an optical component which allows the light beam to pass through the liquid, and a support plate which carries the infrared source and the receiving device. The liquid to be analyzed circulates through a loop formed by walls in the form of an arch of the optical component and by a projection of the housing in the optical component. A sealing gasket is compressed between the optical component and the housing, in order to prevent any diffusion of liquid on the interior of the housing.
Abstract:
Wearable apparatus for monitoring various physiological and environmental factors are provided. Real-time, noninvasive health and environmental monitors include a plurality of compact sensors integrated within small, low-profile devices, such as earpiece modules. Physiological and environmental data is collected and wirelessly transmitted into a wireless network, where the data is stored and/or processed.
Abstract:
Disclosed herein is an apparatus for providing passive correction for thermal effects on a mounted mechanical component. Further disclosed is a wafer inspection system employing the passive thermal effect correction apparatus.
Abstract:
An optical sensor holding device adapted to be integrated with a flexible bag, said device comprising a bag attachment part made from a material that can be welded to the flexible bag; a sensor attachment part made from a material to which an optical sensor spot can be attached, wherein the sensor attachment part is forced into an opening in the bag attachment part that is slightly smaller than the sensor attachment part such that the sensor attachment part is kept firmly in place and leakage is minimized.
Abstract:
A sample investigation system (ES) in functional combination with an alignment system (AS), and methodology of enabling calibration and very fast, (eg. seconds), sample height, angle-of-incidence and plane-of-incidence adjustments, with application in mapping ellipsometer or the like systems.
Abstract:
A system for lighting a stent, i.e., providing an illumination source, to facilitate the capturing of an image of the stent. The lighting is provided so that an image capturing device, e.g., a digital camera or system, will capture an image that distinctly shows the difference between the stent and any surface upon which the stent is mounted, in addition to sharply defining the edges of the stent struts.
Abstract:
A body panel smoothness inspection light support system is provided having a movable joint and a rotatable sliding contact electrical power connection, minimizing the tendency for a power cord to wear or fray.
Abstract:
A device and method are provided for use with a noninvasive optical measurement system, such as a thermal gradient spectrometer, for improved determination of analyte concentrations within living tissue. In one embodiment, a wearable window is secured to a patient's forearm thereby isolating a measurement site on the patient's skin for determination of blood glucose levels. The wearable window effectively replaces a window of the spectrometer, and thus forms an interface between the patient's skin and a thermal mass window of the spectrometer. When the spectrometer must be temporarily removed from the patient's skin, such as to allow the patient mobility, the wearable window is left secured to the forearm so as to maintain a consistent measurement site on the skin. When the spectrometer is later reattached to the patient, the wearable window will again form an interface between the spectrometer and the same location of skin as before.
Abstract:
A sensor mounting system having a suction cup array is disclosed. In one application, the system eases the initial positioning of the calorimeter on the screen to be measured, minimizes the force applied to the screen upon which it is mounted, and minimizes the distortion in the mounted area of the screen surface. In addition, the mounting system can be configured so that the distance from the colorimeter sensor to the screen will not significantly change over time. Such positional stability operates to improve SNR. The mounting system is further adapted for ease of removal from the screen upon which it is mounted. Applications not only include a mount for low to high accuracy calorimeters, but also for other measurement devices that can benefit from advantages of the present invention. Injection molding manufacturing techniques can be employed in fabrication of the system.
Abstract:
An apparatus for holding a generally flat color sample in a plurality of fixed and repeatable positions in proximity with the optics of a portable color instrument with a uniform and repeatable force. The apparatus has a platform upon which the portable color instrument is secured, a sample stage with multiple index planes upon which a color sample is placed, and a device which urges a pressure foot against the color sample, thereby holding the color sample in position on the stage with a uniform and repeatable force.
