Abstract: A method of controlling a washing machine includes rotating a motor for driving an inner shaft in a first direction, and aligning a clutch to a reference position corresponding to one of a maximum lowered position and a maximum raised position. The motor is rotated by a preset reference alignment angle in a second direction to align the clutch from the reference position to a starting position corresponding to one of an upper limit and a lower limit of a preset agitating control section. The upper limit of the agitating control section is spaced downward by a first distance from the maximum raised position, and the lower limit of the agitating control section is spaced upward by a second distance from the maximum lowered position. The motor is rotated by a starting alignment angle set according to a displacement of the clutch ranging from the starting position to a target position corresponding to the other one of the upper limit and the lower limit so that the clutch is moved from the starting position to the target position.

Abstract: In the present disclosure, a structure of a 3-dimensional space measurement device is maximally simplified to be easily carriable by a user to measure a 3-dimensional spatial data. For simplifying the structure, a light transmission unit and a light reception unit are fixed to a support plate, and the support plate is fixed to a rotation unit. Provided are a 3-dimensional space measurement device capable of adjusting a rotation angle of the rotation unit and a tilt angle of the support plate to efficiently measure a distance and space, and a measurement method of a distance and space for making 3-dimensional spatial data.

Abstract: A control method for a washing machine includes: a mode change step in which the configuration of a coupler is moved by operating a solenoid module in such a way that a drive shaft for spinning a pulsator and a dewatering shaft for spinning a washing tub are axially coupled or decoupled; and a mode check step in which a drive motor for rotating the drive shaft is operated and the load of current outputted to the drive motor is sensed, the mode check step comprising a coupler setting step in which, if the load of current outputted to the drive motor does not satisfy a set load value, the solenoid module is operated to reposition the coupler.
