Abstract: A putting practice apparatus for evaluating the striking speed and tempo of a putter includes: an emitting unit (100) that emits light and is provided in a first sensor installation part; a light receiving unit (200) that receives the light emitted from the emitting unit (100); a speed detecting unit (300) and a position measuring unit (400) which respectively detect the speed and measure the position of the golf ball (1); a calculation control unit (500) for performing calculations in order to detect the initial position value of the golf ball (1) as measured by the position measuring unit (400) and the movement speed (Vb) and the moving distance (Hb) of the golf ball (1) as measured by the speed detecting unit (300); and a storage unit (600) for storing the measured speed (Vb) and the measured distance (Hb) of the golf ball (1).

Abstract: An exerciser includes: sensor installation units provided to be spaced apart from and face each other in a direction parallel; a radiation unit for radiating light, in a first sensor installation unit; a light receiving unit for receiving the light radiated from the radiation unit, in a second sensor installation unit; a speed detection unit for detecting a speed of the golf ball by checking a moment the golf ball passes; a position measurement unit for measuring a position of the golf ball; an operation control unit for performing calculation to detect an initial position value of the golf ball and a moving speed Vb and a moving distance Hb of the golf ball; and a storage unit for storing the measured speed Vb and distance Hb of the golf ball.

Abstract: A pillow type neck massage device with adjustable massage intensity, includes: a base board; an upper cover coupled to the base board to support a user's rear neck region; and a massage unit disposed on the base board to massage the user's rear neck region, wherein the massage unit has a body shape measurement module adapted to measure a shape of the user's rear neck region at the time when the user rests his or her head on the pillow type neck massage device.

Abstract: Provided is a dust cleaning robot for removing dust built up on dust collecting plates facing each other at a predetermined interval. The dust cleaning robot includes: a rail arranged on sides of the dust collecting plates; and a transfer robot running along the rail and having a climbing cleaning robot for cleaning up dust built up on the dust collecting plates while climbing the sides of the dust collecting plates.

Abstract: A dust cleaning robot includes: a climbing cleaning robot unit for climbing side surfaces of a dust collection plate to remove dust accumulated on the dust collection plate; and a transfer robot unit operating with the climbing cleaning robot unit mounted thereon to transfer the climbing cleaning robot unit to the side surfaces of the dust collection plate so that the climbing cleaning robot unit is fixed to outer walls of the dust collection plate.
