ABSTRACT:
The present invention provides a method and apparatus for monitoring an infusion pump (10). The method and apparatus provides an encoder (101) which is used with a motor (65) of the infusion pump (10) and a monitoring method which effectively provides rotational directional information. The present invention utilizes a state transition of a first switch (111) indexed against a constant signal from a second switch (113) corresponding to the center of a flag (117) or sector (119).
