The generation of a hall voltage within a semiconductor film of an integrated hall effect sensor uses the flow of a current within the semiconductor film when subjected to a magnetic field. The film is disposed on top of an insulating layer, referred to as buried layer, which is itself disposed on top of a carrier substrate containing a buried electrode that is situated under the insulating layer.

Method and apparatus for determining the condition of a control element
A circuit (70) is provided for determining a position of a control element (24) arranged in proximity to an electro-magnetic field of a solenoid coil (22) for movement in one direction toward one stopped position relative to the solenoid coil in response to increasing electrical current flow through the solenoid coil and for movement away from the one stopped position relative to the solenoid coil in response to decreasing electrical current flow through the solenoid coil. The circuit includes a first detector circuit (36) operative to measure first current fluctuations during increasing current flow through the solenoid coil and to determine the occurrence of a pull-in spike based on a comparison of the first current fluctuations and a first prescribed value to identify when the control element reaches the one stopped position.
