Abstract: A control assembly includes a locking device having at least a first mode of operation and a second mode of operation, the locking device configurable to change from the first mode of operation to the second mode of operation. The locking device has a non-contact sensor and a microcontroller. An independent communicator is configured to communicate configuration data to the microcontroller. The microcontroller is configured to change from the first mode of operation to the second mode of operation using configuration data received from the independent communicator.

Abstract: An inductive proximity sensor is disclosed. The proximity sensor includes a source circuit with an inductive element configured to deliver energy to a resonator when a source current is changed. In various embodiments, the source current is provided a step current source. In various embodiments, the source current is provided by constant current source coupled to the inductive element by a switch. Apparatus and methods for operating the inductive proximity sensor are disclosed.
