  • Publication number: 20220015326
    Abstract: Tools in an automatic milking arrangement are picked up by using a robotic arm (110). The robotic arm (110) moves a camera (130) to an origin location (PC) from which the camera (130) registers three-dimensional image data (Dimg3D) of at least one tool (141, 142, 143, 144). The three-dimensional image data is processed using an image-based object identification algorithm to identify objects in the form of the tools and hoses (152). In response to identifying at least one tool, a respective tool position (PT1, PT3, PT4) is determined for each identified tool based on the origin location (PC) and the three-dimensional image data. Then, a grip device (115) is exclusively controlled to the one or more of the respective tool positions (PT1, PT3, PT4) to perform a pick-up operation. Thus, futile attempts to pick-up non-existing or blocked tools can be avoided.

  • Publication number: 20210392842
    Abstract: In picking up tools in an automatic milking arrangement, the positions of the tools are determined by registering, via a camera at an origin location, three-dimensional image data representing the tools whose positions are to be determined. Using an algorithm involving matching the image data against reference data, tool candidates are identified in the three-dimensional image data. A respective position is calculated for the tools based on the origin location and data expressing respective distances from the origin location to each of the identified tool candidates. It is presumed that the tools have predefined locations relative to one another. Therefore, any second tool candidate is disregarded, which is detected at a separation distance from a first tool candidate when the separation distance exceeds a first threshold distance in relation to the predefined relative locations.

It is presumed that the tools are arranged according to a spatially even distribution relative to one another. Therefore, any tool candidate is disregarded, which is detected at such a position that the position for the candidate deviates from the spatially even distribution.

  • Patent number: 10361605
    Abstract: A method and a device for protecting an electric motor in a pod unit for propulsion of marine vessels against shaft bending shocks when the blades of the pod propeller hit ice blocks or other hard objects, said motor having a drive shaft, a rotor and a stator, said shocks tending to momentarily bend the drive shaft (3) to such an extent that the rotor (41) will come into contact with the stator. The rotor is prevented from coming in detrimental contact with the stator by providing at least two members, which together form a radial plain bearing having mating arcuate bearing surfaces, which during normal operation of the motor are spaced from one another by a gap and come in contact with one another only at extreme loads with short durations.

  • Patent number: 9567200
    Abstract: A vented keg closure (1) for use with a keg (30) that contains a fermenting beverage, with the closure (1) comprising a filter member (41) disposed within an airway of the closure (1) that communicates between an internal headspace (36) of the keg (30) and an environment external to the keg (30). The closure (1) has a first configuration wherein the filter member (41) is located at a first position at which it filters gas flowing through the airway. The closure (1) also has a second configuration wherein the filter member (41) is located at a second position at which gas flow through the airway can be increased by at least partially bypassing the filter (41). The extent of movement between the first and second configurations is controlled by the gas pressure difference across the airway.

  • Patent number: 9367917
    Abstract: The co-registration error can be estimated by performing a number of additional iterative co-registrations, each iteration having a starting point dictated by the found co-registration transformation, and using a set of initial parameters different to that of the co-registration being tested. The spread in the resulting co-registrations can then be used as the estimate of the co-registration error. The variations in the set of initial parameters can include (i) the candidate transformation which the iteration uses as its starting point, adopting starting points that are offset from the co-registration being tested, (ii) the sample points used for the mutual information metric (or whichever metric is used to optimise the transformation), and (iii) the region-of-interest that is selected. Ideally, all three are varied to some extent within the plurality of additional co-registrations that are performed, and an average value is taken.

  • Patent number: 9105096
    Abstract: An apparatus and method of segmenting an image using scribble segmentation is provided. An image is segmented by constraining the membership value of a subset of image elements, solving a weighted biharmonic equation subject to the constrained membership values wherein the weights are determined from similarities between image elements, and determining the final segmentation based on the membership value of each image element. An image may also be segmented by constraining a membership value of a subset of image elements, determining the unknown membership values given the constraints by solving a linear equation system using a multigrid technique, and updating a coarser level of the multigrid hierarchy to account for additional constraints using patch matrices.
