Abstract:
A method and an apparatus measure an actual responsive time for a relay and control the open/close timing for the relay. The apparatus comprises a microprocessor and two conversion units. One conversion unit processes an input sinusoidal signal for the microprocessor and the microprocessor sends a control signal to energize or de-energize a coil of the relay at an arbitrary time point. Another conversion unit senses a waveform change after the switch of the relay and sends a state signal to the microprocessor. Therefore, the microprocessor can obtain an actual responsive time of the relay by the difference between the control signal and the state signal. The microprocessor will apply next control signal with a time lead of the responsive time before next zero-crossing point to achieve zero-crossing switch for the relay.
Abstract:
A double-deck wheel rim cover includes a wheel rim cover body formed integral with a plurality of support studs in the center portion of the inner side, with each support stud having a combining hole. A combining plate is fixed on the support studs, having a hollow combining shaft provided vertically in the center and having a combining hole. An inner decorative member is provided with a bearing in the center for receiving the combining shaft of the combining plate. The wheel rim cover body is further bored with plural windows to let the motion of the inner decorative member be seen therethrough. The inner decorative member is also provided with a weight-balancing member. When the automobile runs, there will produce a visual effect of different rotating speed of both the wheel rim cover body and the inner decorative member, acquiring functions of displaying both static and dynamic decoration.
Abstract:
A wheel rim cover includes a cover body and a decorative cover combined at an outer side of the cover body. The cover body has a plurality of fixing members protruding sidewise on an inner surface spaced apart equidistantly in a circle and fixed with a circular ring. The cover body has a plurality of hollow tubes, and a coil spring fitting around each hollow tube. The decorative cover has a diameter larger than that of the cover body, and a plurality of threaded rods standing sidewise on an inner surface with a washer and a nut. The threaded rods directly extend through the hollow tubes and the coil springs, engaging the nuts to press the coil springs. Thus the wheel cover has an elevated effect of visual appearance and a shock-absorbing function.
Abstract:
A connector is provided. The connector includes a connector body, a signal transmitting unit, a cover, a fastening plate, and an extension plate. The connector body has side walls to enclose an assembly hole. The signal transmitting unit is disposed in the assembly hole. The cover has a first end, a second end, and a first pivot and is disposed outside the assembly hole. The first end and the first pivot are disposed on two ends of a side case of the cover. The second end is opposite to the first end while the first pivot is axially connected to one side of the assembly hole. The fastening plate has a second pivot opposite and parallel to the first pivot. The second pivot axially connected to the side wall around the assembly hole. One end of the extension plate has a third pivot parallel to the first pivot and is rotatably connected to the fastening plate. The other end of the extension plate has a pressing portion to press the second end of the cover from outside to make the cover rotates toward the connector body and press the signal transmitting unit.
Abstract:
A multi-directional mounting faceplate for managing a plurality of cables is provided. The mounting faceplate includes a faceplate body and a nose cover, wherein the faceplate body has an opening disposed about the center of the faceplate body. The cross-sectional shape of the nose cover is similar to the shape of the opening. The nose cover has two side plates and a linking plate which is connected between the two side plates, such that the nose cover can be rotatably connected to the faceplate body to change the open direction of the mounting faceplate.
Abstract:
The present invention provides a foldable patch panel. The foldable patch panel includes a first frame, a second frame, and a pivot unit. The pivot unit is connected to the first frame and the second frame, respectively, so that spinning center of the first frame and the second frame is the pivot unit. Besides, the first frame and the second frame are separably engaged with each other and form an obtuse angle.
Abstract:
A waterproof sensing device including a base, a rear cover, a sensing module, and a lens is provided. The rear cover is selectively rotatably disposed on the base, wherein the rear cover has a side wall to enclose an accommodation space. The sensing module is disposed in the accommodation space. The lens covers the rear cover on the edge of the side wall of the rear cover and seals the accommodation space. A waterproof treatment is disposed between the lens and the edge of the side wall, such that moisture is prevented from intruding into the accommodation space to cause damage, no matter where the sensing device is disposed.
Abstract:
A security socket for use with a panel having at least one assembly hole is provided. The security socket includes a socket and a security unit. The socket has a slot and is inwardly connected to the assembly hole of the panel. The security unit is outwardly assembled with the assembly hole of the panel to be engaged with the socket. The security unit has a protrusion and a through hole corresponding to the slot of the socket, and the protrusion perpendicularly extends from one side of the through hole, wherein the protrusion further has an insertion hole.
