Abstract
A food preparation apparatus is presented that has fast-stop capability. It includes a base unit, a mixing container attached to the base unit, a mixing tool configured to extend into and move within the mixing container, and a motor within the base unit. The motor is configured to provide a torque to the mixing tool. A control unit within the base unit is connected to the motor. A contact sensor is connected to the control unit, and the control unit is configured to stop rotation of the motor when the contact sensor detects a touch of a human hand. In some cases, contact with the mixing tool stops the motor, and in other cases, contact with an outer surface or user interface of the base unit stops the motor.
