Abstract: A boundary positioning device is adapted to pre-record a boundary of a to-be-worked area where an automatic mechanical equipment will be working. The boundary positioning device includes a machine frame, two wheels, a push rod, and a positioning module. When the boundary positioning device moves along the boundary, one of the wheels is located inside the to-be-worked area as an inner wheel, and the other one of the wheels is located outside the to-be-worked area as an outer wheel. The push rod extends rearwardly and upwardly from a rear side of the machine frame. The positioning module is disposed on the machine frame, and is spaced apart from the outer wheel by a distance same as a distance between a positioning unit and an outside-located wheel, which is located outside the to-be-worked area when the automatic mechanical equipment moves along the boundary of the automatic mechanical equipment.

Abstract: A noise-reduction device for a wind turbine and the wind turbine applied thereof are introduced. The noise-reduction device has a body. The body has a connection portion and a spoiler. The connection portion is concavely disposed on one side of the body and corresponds in shape to the wind turbine's blade so as to be fixed to a confronting edge of the wind turbine blade. The spoiler is disposed on the opposing side of the body. As soon as the wind turbine blade is driven by wind, the spoiler stirs air and guides the air across two sides thereof. When guided by the spoiler, airflows turn into vortexes on the wind turbine blade; hence, the chance that the wind turbine will stall and generate noise is greatly reduced.

Abstract: A universal jig is provided for clamping wind turbine blades. The jig has a rectangle-like shape forming a space for clamping a blade at the blade root or the blade body. The jig comprises a set of vertically-moving parts; a set of horizontally-moving parts; a plurality of adjusted pads; and a plurality of positioning parts. The vertically-moving parts comprise two upper connecting posts and two lower connecting posts sheathed with each other separately to form two length sides of the jig. The horizontally-moving parts comprise two left connecting posts and two right connecting posts. The adjusted pads are locked on the left and the right connecting posts. The positioning parts are locked at the upper and the lower connecting posts of the length sides of the jig and are locked at the left and the right connecting posts of the width sides of the jig.

Abstract: A thermal humidifier includes an upper housing provided with a steam outlet for conveying steam into a room and combined with a fundamental base having a PTC heating tube installed therein. A water-absorption member is mounted around the PTC heating tube and has a large portion soaked in a water box for absorbing liquid or water from the water box. The water-absorption member, after fully soaking up water, contacts with the PTC heating tube to enable the PTC heating tube to quickly heat the water of the water-absorption member to produce steam to be sent into a room through the steam outlet of the upper housing.

Abstract: A float switch of a humidifier at least includes a main body, a water tank and a float switch. The main body has a base located at a bottom and provided with a water tank groove and a water basin having a projected portion formed at a bottom. The water tank possesses a water outlet with plural ribs to engage with a float, a circumferential wall used to combine with a protective hood of the float switch, and a space formed between the water outlet and the circumferential wall for containing the float. The float switch is set between the water tank and the water basin, used to automatically fill water in the water basin by means of the float. When the water tank is separated from the main body, a compressing end of a pressing plate is to push up the float enabling a water stopper to seal the water outlet to prevent water from leaking outside.

The data switch detector selects an output pulse signal from a specific switch when the data switch detector senses a logic state change in the received data signal. The input-signal recovery circuit can prevent data error from error accumulation due to physical difference of crystal oscillators.

Abstract: A humidifying fan includes a base, a water swinging device and a fan device. The base has a water tank for storing an appropriate amount of water or other liquids, and an atomized water hole. The water swinging device has a power element and a water swinging fan connected with a suction tube extending in the water tank and having slots in its inner wall and plural water exits.
