Publication number: 20170115145Abstract: Milk meter for measuring a flow rate of a milk flow, provided with an inlet, an outlet, and a liquid flow path from the inlet to the outlet. The milk meter has a measuring chamber and a float in the measuring chamber configured to float on milk. The milk meter determines the flow rate from the level of milk and the milk meter is provided with a magnetic unit for generating a magnetic field and the magnetic field varies in height direction of the measuring chamber, and the float has an electronic measuring unit for measuring the strength of the magnetic field. The measured strength of the magnetic field is a measure of the height at which the float is floating on the milk and the measured strength of the magnetic field is a measure of the flow rate of the milk flow.Type: ApplicationFiled: October 13, 2016Publication date: April 27, 2017Applicant: N.V.

Publication number: 20170112104Abstract: The invention provides a system and a method for determining a physiological condition of a ruminant. The system comprises a sensor unit and a calculating unit. The sensor unit generates a stream of measuring data. that are indicative of a movement condition of the ruminant. The calculating unit uses a neural network for calculating a stream of condition data from the stream of measuring data. The condition data indicate a physiological condition of the ruminant.Type: ApplicationFiled: October 6, 2016Publication date: April 27, 2017Applicant: N.V.

Publication number: 20170100045Abstract: A measuring device for measuring physiological data of a mammal comprising a measuring unit, to be worn by the mammal, with a first and second module. The first module comprises a light source and the second module comprises a sensor unit for measuring an intensity of a fraction of the light delivering a measuring signal. There is a synchronization means for pulsewise activating the light source synchronously with the second module, wherein the measuring signal is indicative of the value of the intensity measured during the pulsewise activation. The synchronization means comprises an energy transmitting unit and a detector which is part of the other one of the first and the second module, in an operating condition the energy transmitting unit pulsewise generates an electromagnetic field, and the detector receives this field and generates therefrom a supply voltage for use in that other module.Type: ApplicationFiled: October 7, 2016Publication date: April 13, 2017Applicant: N.V.

Patent number: 9220242Abstract: A method for monitoring movements of an animal, wherein the animal is provided with a device having sensor means for detecting movements, and generating at least a signal with information about detected movements of the animal. The device is further provided with a control unit for processing the information in the signal and for storing the processed information and transmitter means for transmitting information stored in the control unit. The method comprises: storing in the control unit a number of predetermined-type movements counted during a predetermined set of periods which comprises a number of successive first periods, and transmitting a number of the stored numbers of counted movements at moments which depend on the number of detected predetermined-type movements in at least one of the past first periods and/or depend on at least one of the stored orientations of the sensor means.Type: GrantFiled: April 12, 2012Date of Patent: December 29, 2015Assignee: N.V.
