Abstract
An electric foldable bed capable of being adjusted to a memorized position has a fold bed having motors connected to a headboard and a footboard. A microcomputer is installed on the bed frame and used for controlling the motors. The microcomputer has a computing section, a memory section, a register section and a comparing section. The computing section detects a position of each motor and computes elevation angle data provided by the memory section, the register section and the comparing section. The memory section is used to store predetermined elevation angle data, the register section is used to receive control commands and store the elevation angle data input by the computing section. The comparing section is used for comparing the elevation angle data from both the memory section and the register section. The sensor is installed onto each motor and used for sensing a rotational number count of the motor.
