Memory programming methods and memory systems are described. The logic module is further configured to read via a non-contact interface device data from an authorization storage device and to assign the reader to the card based on the device data for making operable the reader-card interaction. Resistance change in the potentiometer can be used by an electronic circuit to provide the electronic output of the differential pressure remotely to a data acquisition system or control electronics. When the arm member is situated at the first status, the arm member relatively supports the body with respect to the reference point of the body. The programmable nonvolatile register uses a logic switch or a nonvolatile resistive memory device whose resistive state can be set by flowing a controlled current through it.
