Abstract:
An egg identification system (100) for determining viability of an avian egg (1) is provided. Such a system (100) includes an emitter assembly (200) configured to emit electromagnetic radiation toward an egg (1). A detector assembly (300) is axially aligned with the emitter assembly (200) to detect electromagnetic radiation transmitted through the egg (1). The detector assembly (300) is spaced-apart from the egg (1) during operation thereof such that the detector assembly (300) does not contact the egg (1). The detected electromagnetic radiation is processed using transmission spectroscopy analysis, such as infrared spectroscopy or fluorescence spectroscopy, to determine whether the egg (1) is viable, e.g. non dead, rotted or clear. An associated method is also provided.

Abstract:
A reagent card analyzer comprises an optical signal source configured to transmit an optical signal and an optical signal detector spaced a distance from the optical signal source to define an optical signal path into which the optical signal is transmitted, the optical signal detector configured to detect the optical signal and to output an electrical signal indicative of the optical signal. A reader is configured to read a reagent pad of a reagent card. A reagent card moving mechanism is configured to move the reagent card having the reagent pad including a leading and trailing end through the optical signal path. An optical detector interface is electrically coupled with the optical signal detector and configured to receive electrical signals and to output a pad detect signal indicative of at least one of the leading and the trailing end as the reagent card is moved through the optical signal path.
Abstract:
A method for counting the number and measuring the intensity of light pulses produced in a scintillator by the chemiluminescence labels or radioisotopes used in biochemical applications in plane-like samples (13) so that in addition to the intensity of the light pulses, also the position of each light pulse is determined. An image detector (20) is used in measuring so that the light-sensitive surface of the image detector and the sample (13) are brought as close to each other as possible.

Abstract:
A plasmon resonance (PR) system, instrument, and/or device and configurations thereof for measuring molecular interactions is disclosed. In some embodiments, the PR system, instrument, and/or device is a localized surface plasmon resonance (LSPR) system, instrument, and/or device. In other embodiments, the PR system, instrument, and/or device is a surface plasmon resonance (SPR) system, instrument. The PR system, instrument, and/or device may include, for example, force feedback for reliable flow cell sealing, optical feedback for reliable flow cell sealing, local thermal control of an LSPR chip (e.g., a ring Peltier, a continuous Peltier), dual displacement pumps for constant flow delivery to a microfluidic device, a dual channel LSPR sensor, and any combinations thereof.
Abstract:
A testing unit to test a liquid sample applied on a measurement surface in an indicator section on a test piece by using a brightness distribution. The testing unit comprises an irradiation part that irradiates the measurement surface with light; an imaging part that obtains images of the measurement surface; a generating part that generates a determination index based on the imaging data; and a determination part that executes determination on a measurement item, using the determination index. The determination index is based on a brightness of the measurement surface when the measurement surface does not include a specular reflection region. The determination index is based on a brightness of a remnant region of the measurement surface excluding the specular reflection region when it is determined that the measurement surface includes a specular reflection region.
Abstract:
A device for use in the detection of binding affinities, the device comprising a planar waveguide (2) arranged on a substrate (3), and further comprising an optical coupler (41) having a predetermined length for coupling coherent light (1) of a predetermined wavelength into the planar waveguide (2) such that a parallel beam of coherent light propagates through the planar waveguide (2) with an evanescent field (11) of the coherent light propagating along an outer surface (21) of the planar waveguide (2). The outer surface (21) of the planar waveguide (2) comprises binding sites thereon capable of binding target samples to the binding sites such that light of the evanescent field (11) is diffracted by target samples bound to the binding sites. The binding sites are arranged along a plurality of predetermined straight lines (7) running parallel to one another with a constant distance between adjacent straight lines. The predetermined straight lines (7) are arranged at an angle relative to the direction of propagation of the evanescent field (11) such that the coherent light (12) diffracted by the target samples bound to the binding sites impinges under a diffraction angle relative to the straight lines onto a further optical coupler (8) arranged in a portion (10) of the planar waveguide (2) outside the beam of coherent light propagating through the planar waveguide. The further optical coupler (8) couples the diffracted coherent light (13) out of the planar waveguide (2) such as to interfere at a predetermined detection location (9) with a difference in optical path length which is an integer multiple of the predetermined wavelength.
