DEFINITION

Classification: 123/406.64

Memory addressed by engine speed or load:

Subject matter under subclass 406.6 wherein (a) the information storage section has a label (e.g., integer, symbol, other set of characters, etc.) designating a location where the information is stored for subsequent recall, and (b) the information is directed to the respective label by (1) a signal indicative of the rate of rotation of the elongated member, or (2) a signal indicative of the resistance to rotation of the elongated member.
