Abstract:
A perforated-structure body having a plurality of apertures that penetrate from a first main surface to a second main surface of a perforated plate. Support substrates are stacked on at least one of the first main surface and the second main surface of the perforated plate so as to define a portion through which at least one of the apertures is exposed.
Abstract:
A system for characterizing a bi-directional reflectance distribution function scattered light pattern of a portion of a sample is disclosed. The system can comprise a hemispherical member comprising an reflective inner surface; an entrance port operable to receive electromagnetic radiation from an electromagnetic radiation source; a first reflective optical element operable to receive at least a portion of the electromagnetic radiation and to direct the at least the portion of the electromagnetic radiation onto the portion of the sample to be characterized; a wide-angle lens operable receive the electromagnetic radiation that was specularly reflected and diffusely scattered from the portion of the sample onto the inner surface of the hemispherical member; and an imaging device operable to record intensity information imaged by the wide-angle lens to characterize the bi-directional reflectance distribution function scattered light pattern of the portion of the sample.
Abstract:
An alignment unit for a laser analyzer that performs measurements on a substance inside a chamber includes a first alignment flange that attaches to the chamber, a second alignment flange that attaches one of a launch unit or detect unit of the laser analyzer to the chamber, an alignment stud for adjusting horizontal and vertical alignment of the second alignment flange, an optical window that keeps the chamber closed when the one of the launch unit or detect unit is removed from the chamber, and a sealing member provided between the second alignment flange and the optical window.
Abstract:
The present invention is directed to a reflectometer-based apparatus and method for colorimetric analysis. Advantageously, the present invention includes use of a test strip provided with an aperture over which a translucent colorimetric, indicator-bearing matrix is affixed. In addition, the present invention beneficially includes a test strip holder that includes a test strip-holding channel provided with a white background.
Abstract:
The present invention relates to a backlight inspection equipment comprising a carrying platform configured to dispose a backlight to be inspected and an inspection plate movably disposed relative to the carrying platform. The inspection plate moves from a first position to a second position. When the inspection plate is disposed at the first position, a first light emitting region of the backlight to be inspected is exposed and a second light emitting region which is a region other than the first light emitting region is blocked. When the inspection plate is disposed at the second position, a third light emitting region of the backlight to be inspected, which is different from the first light emitting region, is exposed, and a fourth light emitting region which is a region other than third light emitting region is blocked.
Abstract:
An inspection system is configured for use with a conveyer apparatus including carrier bars. Each carrier bar conveys pellet-shaped articles along a predetermined path. The inspection system includes at least one camera unit for sensing a predetermined characteristic of the pellet-shaped articles, a removal unit, and a controller. The removal unit, downstream from the at least one camera unit, removes selected pellet-shaped article(s) from the carrier bar(s) depending on whether the characteristic is sensed by the at least one camera unit. The controller is in communication with the at least one camera unit and the removal unit. The controller provides a signal to the removal unit in accordance with the sensed characteristic. The removal unit includes a rotatable ejection drum having extended vacuum nozzles along its length, equal to the number of articles conveyed in each carrier bar. Each vacuum nozzle selectively removes article(s) from the carrier bar(s) by suction.
Abstract:
Methods, systems, and computer readable media for determining physical properties of a specimen in a portable point of care device are disclosed. According to one aspect, a method includes placing a specimen onto an active surface that includes a plurality of microposts extending outwards from a substrate, wherein each micropost includes a proximal end attached to the substrate and a distal end opposite the proximal end and generating an actuation force in proximity to the micropost array that compels at least some of the microposts to exhibit motion. The method further includes detecting light that is emitted by an illumination source and interacts with the active surface while the at least some microposts exhibit motion in response to the actuation force, measuring data that represents the detected light interacting with the active surface, and determining at least one physical property of the specimen based on the measured data.
Abstract:
The present invention discloses a biosensor for visual detection of an analyte, based on the light to heat conversion properties of metal nanoparticles: the analyte is visually detected by the color change in the support areas (where the analyte is present), produced as a result of the heat generated by the metal nanoparticles where they are irradiated with an external light source. Use of said biosensor in a method for the detection of analytes is also claimed.
Abstract:
A pathogen detection system including a specimen support for supporting a test specimen sample to be analyzed, a coherent light source, an optical detector and an analyzer electronically coupled to the optical detection. The coherent light source is operable to direct a coherent light beam at said specimen support to break down and at least partially atomize said test specimen sample. The optical detector is positioned to detect a spectral signature of electromagnetic radiation emitted by the partial atomization of the test specimen sample. The analyzer compares the detected spectral signature to one or more predetermined spectral signatures for one or more pathogens.
Abstract:
A Raman detecting system includes a bowl shaped metal nanostructure array configured to load a sample, a projecting module configured to project a beam of light to the bowl shaped metal nanostructure array, and a receiving module configured to collect the light scattered by the bowl shaped metal nanostructure array. The bowl shaped metal nanostructure array includes a substrate having a surface and a number of particle-in-bowl structures located on the surface of the substrate. Each particle-in-bowl structure includes a bowl shaped concave structure and a protruding member protruding from the bowl shaped concave structure. The protruding member is integrated with the bowl shaped concave structure.
