摘要： In an adjustable bed, a bending angle of a lift arm is precisely adjusted according to generated signals corresponding to a wheel rotated by a motor of the adjustable bed or according to a current state related to the wheel. The signals are generated according to whether light is obstructed by gratings, according to whether a magnetic force is detected, or according to a change of a magnetic field. The current state is current resistance of a variable resistor disposed near the wheel.
