Abstract

See full text

Multi-sensor sewing machine with automatic needle speed adjustment. In some embodiments, a sewing machine may include a frame, a needle bar, a motor, a first sensor configured to emit first electromagnetic radiation at a first frequency in order to sense relative movement of the fabric and the frame, a second sensor configured to emit second electromagnetic radiation at a second frequency, that is different from the first frequency, in order to sense relative movement of the fabric and the frame, and a processor. The processor may be configured to control a speed of the motor, determine a translational relative movement of the fabric and the frame based on the sensed relative movement of the first sensor and/or based on the sensed relative movement of the second sensor, and, in response to the determined translational relative movement, alter the speed of the motor.
