Patent ID: 8485715

Claim:
A method of controlling blender operation to produce a consistent, blended material comprising the steps of: providing: (a) a blender assembly comprising a blender motor operatively connected to a cutter assembly, wherein the cutter assembly is mounted in a blender jar for blending material placed within the jar; (b) an energy control switch that activates and controls the amount of energy delivered to the motor during operation of the motor; and (c) a feedback sensor electrically connected to the energy control switch, wherein the feedback sensor is adapted to detect an attribute associated with the operation of the motor and send a signal to the energy control switch based on the attribute detected; adding material to the blender jar; activating the blender motor; recording the signal from the feedback sensor to the energy control switch at predetermined time intervals and comparing the signals over time; and deactivating the blender motor when a predetermined relationship is found in the comparison of signals recorded from the feedback sensor.
