Abstract: This disclosure relates to a system for monitoring pasture intake by a grazing animal species. The system comprises a sensor spatially associated with a body part of the animal to generate movement data indicative of movement of the body part of the animal associated with multiple points in time and a processing server. The processing server comprises a data interface to receive the movement data and a processor that is configured to evaluate the received movement data to determine for each of the multiple points in time an indication of a behaviour of the animal at that point in time. Based on the indication the processor determines a time value indicative of a time the behaviour was shown by the animal, and determines a pasture intake value based on the time value.

Abstract: A dual-comparator rectifier circuit of a wireless power receiver includes a receive coil configured to generate a current in response to receiving power through electromagnetic waves from a wireless power transmitter and a bridge circuit. The bridge circuit includes four branches, and one node of each of the four branches is coupled to one of a first node or a second node of the receive coil. A first branch and a second branch of the four branches are coupled to the first node and the second node of the receive coil and include a first circuit and a second circuit, respectively. The first circuit includes a first comparator and a first switch circuit and the second circuit includes a second comparator and a second switch circuit. The first circuit and the second circuit can set a dynamic turn-on threshold for the first switch circuit and the second switch circuit, respectively.
