Title: System and method for identification of individual animals based on images of the back
Inventor: BORCHERSEN Soeren
IPC: A01K29/00
Filed: 2016-06-30
Abstract: The present invention relates to a system and a method for identification of individual animals based on images, such as 3D-images, of the animals, especially of cattle and cows. When animals live in areas or enclosures where they freely move around, it can be complicated to identify the individual animal. In a first aspect the present disclosure relates to a method for determining the identity of an individual animal in a population of animals with known identity, the method comprising the steps of acquiring at least one image of the back of a preselected animal, extracting data from said at least one image relating to the anatomy of the back and/or topology of the back of the preselected animal, and comparing and/or matching said extracted data against reference data corresponding to the anatomy of the back and/or topology of the back of the animals with known identity, thereby identifying the preselected animal. The method and system can be used to monitor feed intake, such as feed intake for dairy cows as well as health status.

Title: Heat exchanger profile
IPC: F28F3/04
Filed: 1982-03-05
Granted: 1983-10-06
Abstract: This corrugated U-profile serves for producing heat exchangers. The advantageous construction with the limbs spread slightly outwards and the outwardly projecting protuberances permits the profiles to be plugged together simply to form heat exchanger ducts for the heat transferring media while preserving the same flow cross-sections. The construction of the U-profile also enables the heat exchanger ducts to be laid in radii. After the individual U-profiles have been plugged together in the desired shape and size, because of the preferable shaping the limb ends of the profiles can easily be machine welded with the projecting protuberances of the adjacent profiles in each case. <IMAGE>

Abstract: A sealing arrangement around an end of a pipe received in a testhead of a hydraulic pipe testing apparatus, which sealing arrangement consists of an elastic sealing ring and an adjacent, rigid support ring of varying diameters. Both rings are mounted in radial recesses in the testhead and encircle the pipe upon its entry into the testhead. The recess for the elastic sealing ring consists of a flat ring located between the sealing ring and the rigid support ring. For a sealing condition, the support ring is contracted to abut the pipe and the sealing ring is caused to be deformed whereby it flows radially outwardly from its recess against the pipe and axially along the pipe towards and away from the pipe's end. In the axial direction away from the end of the pipe, the sealing ring flows around the flat ring to abut the rigid support ring.

Title: Arrangement for determining the wind gradient on board an aircraft
IPC: G05D1/06
Filed: 1986-11-18
Granted: 1988-03-03
Abstract: It is intended to specify an arrangement for determining the wind gradient on board an aircraft. The arrangement can be used for aeroplanes and gliders. The air speed indicator signal on board an aircraft is measured using a pressure probe, such as a pitot tube. In this case, changes in the wind pattern (which varies with position and in time) caused by gusts and wind shear are also measured. It is intended to produce a signal for the wind gradient, without using an inertia platform. For this purpose, a second pressure probe is fitted in the direction of flight, spaced apart from the first pressure probe, and a signal for the wind gradient is calculated from the difference between the two probe pressures. The arrangement is used together with wind shear instruments and warning apparatuses and in total-energy variometers in gliding.

Abstract: A level measuring set for low frequency signals with superimposed direct voltage has a low-pass filter (7) to which is applied the measurement signal and whose output emits a reference potential (UB) which corresponds to the direct voltage. A measurement rectifier (2) forms a positive and a negative direct voltage component (+UM, -UM) superimposed on the reference potential (UB) for the positive and negative half-waves of the low frequency signal, respectively. The reference potential (UB) is applied to a reference point (6) of the measurement rectifier (2). A subtractor (5) receives at its input the positive and negative direct voltage components (+UM, -UM) and emits the level measurement value.
