Abstract
A new and improved method and apparatus is disclosed for detecting a target location with respect to an inductive tank circuit. A sensing field such as an electromagnetic field is established having an amplitude which changes in value due to the presence of a target in the sensing field. A first energy level is provided to maintain the field at an amplitude. A second energy level is provided to achieve a value for the field within the predetermined amount of time after initiation of the field.
