Abstract: A label is described for attachment to an animal. The label includes a transmitting and receiving device having an electric oscillator circuit that, upon closure of the oscillator circuit, generates a periodic electric oscillator signal with an oscillation period for transmitting an electromagnetic beacon signal with the transmitting and receiving device. The label is configured for closing the electric oscillator circuit during a predetermined transmission duration, and is further configured for opening the electric oscillator circuit upon elapse of the predetermined transmission duration, wherein the predetermined transmission duration corresponds to at least one and at least a whole number of oscillation periods of the electric oscillator signal.

Abstract: Milk meter for measuring a milk flow provided with an inlet the milk flow is supplied to an outlet, a liquid flow path extending from the inlet to the outlet, a stabilization chamber in the liquid flow path and a float therein configured to float on milk. The level of milk in the stabilization chamber depends on the flow rate of the milk flow. At least one sensor device for determining the position of the float in the stabilization chamber for determining the flow rate of the milk flow. The milk meter has an outflow channel and an outflow opening in fluid communication with the outlet via the outflow channel. The sensor device has a first and a second coil which have a fixed distance to each other, and a third coil. The first and second coil and the third coil are displaceable relative to each other.

Abstract: 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.
