Abstract:
An egg identification system for determining viability of an avian egg is provided. Such a system includes an emitter assembly configured to emit electromagnetic radiation toward an egg. A detector assembly is axially aligned with the emitter assembly to detect electromagnetic radiation transmitted through the egg. The detector assembly is spaced-apart from the egg during operation thereof such that the detector assembly does not contact the egg. The detected electromagnetic radiation is processed using transmission spectroscopy analysis to determine whether the egg is viable. 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 system for interrogating non-homogeneous liquid samples to locate regions of interest within the samples, and to extract liquid from the regions of interest. The system of the invention is particularly well adapted for use in locating and in thoroughly removing liquid from regions of interest that include even extremely thin, film-like, horizontally extending layers of interest that typically are in the range of about 10 to 50 microns in thickness. The system utilizes a polarized beam of collimated laser light that is projected along a horizontal travel path, that is transmitted through a sample, and that is detected to enable characteristics of the transmitted light beam that have been affected by characteristics of the interrogated sample portions to be studied. By this arrangement, a centrifuged sample of liquid that differs in content at different height levels can be interrogated to locate levels within the sample where one or more layers of components of interest reside that are to be withdrawn from the sample. Withdrawal of liquid components from each such layer is effected by inserting a pipette into the sample to a level where the components reside, and by withdrawing the components through the pipette.
Abstract:
A procedure for photometric measurement of liquids in a reaction vessel in an automatic analyser, with a radiation flow having its course perpendicular to a row of the reaction vessel, so as to provide a reliable and positively operating measuring method for the photometric measurement of the liquids. The procedure is characterized in that the radiation flow and the reaction vessel are in movement relative to each other during the measurement. The invention affords the advantage of improved accuracy of measurement and improved reliability since it becomes possible, by measuring a moving object and at the same time calculating the mean of the radiant flux over accepted portions of the signal, to eliminate the error of measurement introduced by a dirt particle or by a scratch. The invention also concerns a row of reaction vessels employed in the procedure, wherein each reaction vessel is contiguous to the next and separated by a wall. The row of reaction vessels is characterized in that the bottom of each reaction vessel consists of a lens focussing luminescence radiation. This affords the advantage that the lens enables a luminiscence measurement to be performed simultaneously with the photometric measurement.

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.
