Abstract: A method for optical detection of residual soil in lumens of lumened or cannulated devices such as surgical endoscopes, after undergoing a decontamination process (e.g., a washing or rinsing operation). A soil detection system provides an indication of the presence of residual soil within a lumen by detecting luminescent radiation emanating from the soil on the interior of the lumen in response to excitation light.

Abstract: An environmental sensor may include a heat source that heats a metal oxide sensing material. Electrodes may be formed in the metal oxide sensing material that measure the resistance of the metal oxide sensing material to determine the concentration of various gases. The environmental sensor may include an infrared light source that emits infrared light at a given wavelength. An infrared detector and band-pass filter may be used to detect the concentration of a particular gas such as carbon dioxide. In order to reduce power consumption, a heater may act as both the heat source for the metal oxide sensing material and the infrared light source for the infrared detector. The metal oxide sensing material, heater, and infrared detector may be formed in the same enclosure. The enclosure may have an opening that is aligned with an opening in an electronic device housing.

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: Disclosed are methods and apparatus for imaging a rounded edge of a sample, such as a wafer with a beveled edge. In one embodiment, the system includes a curved diffuser having an internal surface for positioning towards the rounded edge of the sample and an external surface opposite the internal surface and light sources for generating a plurality of illumination beams adjacent to a plurality of positions on the external surface of the diffuser so that the diffuser outputs uniform light onto the rounded edge of the sample at a wide range of incident angles. The system further includes a sensor for receiving light scattered from the rounded edge of the sample in response to the incident light and generating a detected signal for generating an image. These elements are partially or entirely integrated into a compact assembly.

Abstract: A method of detecting natural gas releases that includes the step of traversing a target area with a gas-filter correlation radiometer having a field of view oriented towards the target area. The gas-filter correlation radiometer receives reflected radiation in a passband from the target area and produces gas-filter correlation radiometer signals from the received reflected radiation. A surface reflectivity spectral profile of the target area is determined. The presence of methane in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.
