Abstract:
Method and apparatus (100) for determining the viability of eggs (113) primarily designed for eggs of a developed stage, e. g. 16 to 18 days for poultry eggs (approximately 50% into the incubation period), where the animal is too opaque to use transmission of light through the egg for heart pulse detection. At least one light source (107, 108, 109, 110) causes infrared (IR) light to impinge upon the egg. A part of the light, preferably light which has been passed into the air sac (120) and impinged upon the allantois (121), is reflected to an IR detector (111). Viability is determined on the basis of ascertaining whether the received light has a variation due to the action of the heart or variation due to movement of the chick. The invention further relates to a method of vaccinating eggs in ovo, to a method of sorting eggs by gender, to a common body for holding a plurality of IR emitters, and to a computer program.
Abstract:
The invention relates to a fluorometer having a partly transparent mirror (27) through which excitation light is directed to the sample and via which emitted light from the sample is reflected. Thus a high sensitivity and, furthermore, as homogenous a measurement sensitivity distribution as possible within the vessel are achieved. Measuring can be carried out from either above or below. The invention is applicable for use especially when the fluorometer has simultaneously a plurality of samples.
Abstract:
A method and system for inspecting a manufactured part at an inspection station are provided. A supported part is rotated about a measurement axis so that the part moves at predetermined angular increments during at least one rotational scan. A backside beam of collimated radiation is directed at and is occluded by the supported part at each of a first plurality of consecutive increments of movement to create a stream of unobstructed portions of the backside beam in rapid succession passing by and not blocked by the supported part. A frontside beam of radiation is directed at and is reflected by the supported part at each of a second plurality of consecutive increments of movement to create a stream of reflected portions of the frontside beam in rapid succession. The streams of reflected and unobstructed portions are detected at the inspection station to obtain electrical signals which are processed.
Abstract:
A refractometer has a housing (1), a measurement cell (8) arranged in the housing (1), and a lid unit (2). The lid unit has a base plate (3) with a cutout (7) allowing access to the measurement cell, and a lid (4) for covering the measurement cell. The lid is connected to the base plate by way of a hinge. The lid unit also has a lid insert (11, 17, 18, 28, 31, 35, 39) that is arranged replaceably in the lid. The lid unit (2) is detachably connected to the housing by means of a connecting element that is itself connected to the base plate.
Abstract:
A method and a machine for balancing vehicle wheels with weights (18), the method comprising stages of: using a video camera (5, 6, 206) to frame a portion of a surface of a hub (101) of a wheel on which a weight (18) is to be applied, locating, in images of the hub (101) taken by the camera (5, 6, 206), at least a balancing plane (E1, E2) which is perpendicular to a rotation axis (A) of the wheel, piloting at least a pick-up device (8, 9, 209) such as to direct the at least a pick-up device (8, 9, 209) onto a point (P1, P2) of the hub (101) belonging to the balancing plane (E1, E2), detecting, by means of the pick-up device (8, 9, 209) characteristic geometric parameters of the hub (101) at the balancing plane (E1, E2), measuring an imbalance of the wheel, calculating, by means of an electronic calculator (4, 204) an entity of at least a weight (18) to be applied to the hub (101) at the balancing plane (E1, E2), and also calculating an angular position (T1, T2) of the weight (18) in the balancing plane (E1, E2).

Abstract:
The invention relates to an apparatus for measuring physiological parameters of blood conveyed within an extracorporeal circulatory system. Two light sources (1a, 1b) emit light of varying wavelength into a spherical cavity (3) that comprises a reflective inner surface (3a). Light sensor means (2) receives part of the light propagating within the cavity (3). A tube portion of the extracorporeal circulation can be inserted into a second cavity (4) such that the light (La, Lb) emitted by the light sources encounters the boundary surface between the blood and an inner wall of the tube. The light returns to the cavity (3) at least to an extent by means of reflection and/or transmission.
Abstract:
A method of protecting a sensor (300) for use in an environment in¬ cludes: providing a protective enclosure formed in a plurality of sec¬ tions (110a, 110b), at least a first section (110a) of the plurality of sections being movable relative to a second section (110b) of the plurality of sections so that the protective enclosure can be placed around at least a portion of the sensor (300); placing the first section (110a) adjacent the sensor (300) while the first section (110a) and the second section (110b) are in an open state; and moving the second section (110b) to place the first section (110a) and the second sec¬ tion (110b) in a closed state in which the first section (110a) and the second section (110b) encompass the at least a portion of the sensor (300).
