Abstract: A method and control arrangement for controlling an automated crowd gate that operates to form a side of a holding area and moves in relation to an entrance of a destination in order to cause animals located in the holding area to move towards the destination, wherein location data defining individual positions of one or more animals located in the holding area is obtained from a real-time location system, location data, a current position of the crowd gate is obtained, and an operation of the crowd gate is controlled based on the obtained position of the crowd gate and the obtained location data of the animals.

Abstract: Each of multiple entities has a respective attached mobile unit that transmits, periodically, a first radio message with identity information of the corresponding entity. At least three base stations receive the first radio message; and based thereon, forward, via a transmission line, the identity information and timing information indicating when the first radio message was received. A central unit communicatively connected to the at least one transmission line receives, via the transmission line, the identity and timing information from the base stations, and based thereon determines a position of the respective entity. Each mobile unit alters an energy density at which the first radio message is transmitted in response to a trigger input being generated depending on a position of the mobile unit relative to a stationary reference. Thus, the energy resources in the mobile units can be economized while attaining a desired positioning accuracy wherever needed.

Abstract: The disclosure relates to a sorting system for automatically selecting animals to be treated during a treatment period. A first aspect is a sorting system automatically selecting animals to be treated during a treatment period. The sorting system includes an automatic sort gate and a control arrangement receiving, via a user interface, user input indicative of sorting criteria applicable to animal properties and a maximum number of the animals allowed to be present simultaneously in the sorting area. The control arrangement is further configured to monitor a number of animals that enter and exit the sorting area. The control arrangement is finally configured to adjust one or more parameter values of the one or more sorting criteria, based on the monitored number of animals that enter and exit the sorting area. The disclosure also relates to a corresponding method and to a computer program for performing the method.

Abstract: A positioning system has a central unit receiving identity and timing information; and based thereon determines a respective position in an area of each of a set of entities. Each entity carries a mobile unit repeatedly transmitting a radio message including the identity information. The positioning system also contains at least three base stations, each receiving the radio messages from the mobile units; and based thereon, forwards the identity and timing information to the central unit. During a measurement period, the central unit registers positions of the entities as a trace for each mobile unit. The central unit checks whether, during the measurement period a first predefined number of traces are interrupted during a first threshold interval, and the predefined number of traces are interrupted in a first zone, which exceeds a first threshold size. If so, a capacity alarm with respect to the first zone is generated.

Abstract: A sensor arrangement measures a parameter (P) representing a position of a movable platform of a rotary parlor relative to a stationary reference point. Based on the parameter, in turn, a control unit influences the movement of the movable platform. A first transmitter unit with a first transmitter antenna is placed on the movable platform and thus moves along with the movable platform. A first radio signal emitted from the transmitter antenna contains a timing reference and uniquely identifies the first transmitter unit. At least three receiver stations are stationary placed with a respective receiver antenna located such that the first radio signal is received via line-of-sight propagation. Based on the first radio signal and respective propagation times derived from the timing reference in the first radio signal (SID), the receiver stations generate the parameter (P).

Abstract: The operation of a movable platform (110) in a rotary milking parlor (100) is measured by a movement sensor (210) arranged on the movable platform (110). The movement sensor (210) registers micro movements of the movable platform (110) relative to a fix reference frame via a sensor member measuring displacements in at least one dimension, and/or accelerations in at least one dimension. A wireless sensor signal (SW) reflecting the measurements is emitted by a transmitter to a receiver (230) for processing/analysis, for example to derive a movement signature (S) of the movable platform (110) based on a series of measurement values.

Abstract: A holding area and method executed in the holding area arranged at a milking parlor of a farm are provided. A Location System is arranged at the holding area, and is configured to monitor animal movements in at least two directions. The Location System includes a controller, a tag, and transceivers configured to detect signals emitted by the tag, and communicate information with the controller. The method includes determining an arrival time of the animal and/or animal movement, identifying the animal, monitoring a waiting time of the animal in the holding area and/or animal movements of the animal, comparing the waiting time and/or animal movements with a respective reference threshold; and triggering an action, when the reference threshold is exceeded.

Abstract: A method and system for assisting a human in detecting an exception animal, for which an abnormal measurement value has been detected, wherein a geographical position is obtained of the exception animal, a geographical position if obtained of a user equipment of the human, a distance is determined between the obtained geographical position of the exception animal and the obtained geographical position of the user equipment, and when the determined distance is smaller than a threshold limit, an indication is sent to the user equipment confirming the proximate presence of the exception animal.

Abstract: An animal milking method and apparatus wherein a single milk meter measures the total milk flow from all four quarters of an animals udder, and the data generated by the milk meter is used to detect a departure from a predicted milk flow versus time relationship, indicative of an injured teat or an infected udder quarter, for altering the herdsman to a condition which warrants medical inspection of the animal concerned.

Abstract: A method for calibrating milk meters in a milking system includes a milking station having at least one milk meter that measures a value of a milking performance of a milking animal. The method includes the steps: determining a reference value which reflects the amount of milk received from a number of milking animals during a selected time period in a reference unit, retrieving all measured values during the selected time period for each milk meter that by itself contribute to the amount of milk received by the reference unit, comparing the reference value with the sum of all retrieved measured values and calculating a correction function for one of the milk meters, and using the calculated correction function to adjust the measured value from the milk meter.
