Inductive coils are used to provide electrical energy for inductive coupling used to transmit data from identification tag on animal to processing unit

摘要

The stall has a watering station (18) that is used by such as a milk cow. The animal has a data memory element implanted that is read by coils (28) set into the sides of the stall. These are supplied by an ac generator (32). A sensor (34) is used to detect the presence of the cow.
