A detection device, detection method, and compensation method for tool wear, applied to a machine tool including a spindle connected to a tool. A first parameter set including a first cutting depth having a zero cutting depth is set, and the machine tool performs a cutting procedure with the first parameter set to record a first loading rate of the spindle. A second parameter set including a second cutting depth having a non-zero cutting depth is set, and the machine tool performs the cutting procedure with the second parameter set to record a second loading rate of the spindle. A processing device calculates an estimated cutting force according to the loading rates and a machine performance database. A fuzzy logic unit outputs a wear level according to a tool wear database and the estimated cutting force. The machine tool adjusts a cutting locus according to the wear level.

A driving system for a garage door includes a track having an end fixed on an inside of a wall and has an open side that faces upward. A driving assembly is movably received in the track and driven by a motor. The driving assembly includes a connection member to which two ends of a power transferring member are connected. A U-shaped member is movably engaged with the track from an underside of the track and two sides of the U-shaped member are connected to the driving assembly. A link is pivotably connected between the U-shaped member and the garage door. The power transferring member reeves a gear which is rotatably connected to the track and the motor has a driving shaft which is conveniently extended through an opening of the track and engaged with an engaging hole of the gear.

A separation device of an electronic ballast body and a fixing seat includes a body, an electronic ballast, a socket, a fixing seat, and two safety locking members. The body has an inner wall formed with a receiving chamber for receiving the electronic ballast and the socket which is rested on the electronic ballast. The fixing seat has one end locked on a closed end of the body. Each of the two safety locking members is mounted and locked between the body and the fixing seat, so that the body and the fixing seat may be locked with each other, thereby integrally combining the body with the fixing seat. Thus, the separation device may be assembled and disassembled easily and conveniently, thereby facilitating replacement and maintenance of the separation device of the present invention.

A separation device of a lamp holder and a fixing seat includes a lamp holder, a lamp connecting seat, an electrode, a fixing seat, a cover plate, a fixing bracket, and two safety locking members. When the lamp holder registers the fixing seat, the lamp holder is rotated relative to the fixing seat, so that the lamp holder is integrally combined with the fixing seat. Thus, the separation device is assembled and disassembled easily and conveniently. In addition, the lamp can be inserted into the lamp connecting seat only when each of the two safety locking members is exactly locked on the lamp holder and the fixing seat, thereby forming a safety locking effect.
