摘要:
A method for coordinating a tablet computer with at least one other tablet computer to play an audio/video file and a playing system using the same are proposed. The method includes: establishing a wireless connection between a tablet computer acting as a master computer and at least one other tablet computer acting as a slave computer; the master computer generating an arrangement signal at least according to an arrangement of positions of the tablet computers; the master computer generating at least two divisional signals according to the arrangement signal and an audio/video file, each corresponding to a portion of video frame in the audio/video file; the master computer transmitting the divisional signals to the slave computer to enable the master computer and the slave computer to respectively display the portion of video frame corresponding to the divisional signals; and the master computer transmitting a synchronizing signal to the slave computer.

An LED lamp includes a first heat sink, a heat-absorbing member receiving the first heat sink therein, a plurality of LED modules attached to the heat-absorbing member, a second heat sink disposed on the first heat sink and the heat-absorbing member, and a lens coupled to the first and second heat sinks and enclosing the heat-absorbing member and the LED modules therein. The first heat sink has a conducting cylinder which defines a first through hole therein. The heat-absorbing member consists of a plurality of vapor chambers and has inclined outer faces oriented downwardly, on which the LED modules are mounted. The second heat sink includes an annular base which defines a second through hole in a center thereof. The second through hole communicates with the first through hole of the first heat sink.

A protective packaging for protecting an LED module from being damaged during transportation, includes a housing containing the LED module therein and a cover slidably fixed in the housing to cover a top opening of the housing. The housing defines a room to receive the LED module therein. A bottom portion of the housing is concaved to form a space, in which a thermal interface material bonded on the LED module is accommodated. An end of the housing is closed to abut against an end of the cover, and an opposite end of the housing is partially opened to receive an opposite end of the cover. The protective packaging is made from an antistatic plastic and has a wall thickness larger than 0.5 mm.

An LED lamp includes a first heat sink, a pair of second heat sinks arranged at two opposite sides of the first heat sink, a plurality of heat pipes connecting the first heat sink to the pair of second heat sinks, and an LED module mounted on the first heat sink. With the help of good heat conducting capability of the heat pipes, heat generated by LEDs of the LED module can be conducted to the first heat sink and the pair of second heat sinks rapidly, which then dissipate the heat to the ambient air. Each second heat sink consists of a plurality of sheets defining a plurality of gaps therebetween; the gaps extend through top and bottom of each second heat sink. Each second heat sink has a lower portion below a bottom surface of the first heat sink.

An LED lamp includes a heat sink, a plurality of LED modules mounted on the heat sink, a bracket connecting with the heat sink and a cover covering over the heat sink. The heat sink includes a curved base plate and a plurality of fins extending from an inner surface of the base plate. The LED modules are mounted on an outer surface of the base plate, whereby the LED modules radiate light on different directions. The bracket is located above the fins and includes two connecting bars to respectively connect two ends of the base plate. The cover covers over the outer surface of the base plate to protect the LED modules. Heat generated by the LED modules is absorbed by base plate of the heat sink and dissipated into ambient air via the fins thereof.

A vacuum circuit interrupter having a pole unit structure and an operating mechanism structured to move the vacuum circuit interrupter contacts between a first, closed position, wherein a movable contact is coupled to, and in electrical communication with, a fixed contact, and a second, open position wherein the movable contact is spaced from, and not in electrical communication with, the fixed contact, as well as being structured to rotate a housing assembly rotatable portion between a first position, wherein a rotatable terminal is coupled to, and in electrical communication with, a line terminal, and a second position, wherein the rotatable terminal is coupled to, and in electrical communication with, a grounded terminal.
摘要:
The present invention relates to a device and a method for connecting a mobile phone handset to an external keyboard. A multimedia card slot interface is included in the portable keyboard of the present invention, which can be incorporated to the original interface of the handset. In the meantime, a microprocessor and a random access memory are also included in the keyboard. After sending an interrupt command from the handset to the keyboard, by scanning the keyboard, whether the key is pressed or not is determined by the microprocessor and the key value is stored in its own random access memory. When the key value is stored in the random access memory, an interrupt command is sent to the handset by the keyboard. After the handset is ready, the key value will be transferred to the handset via the multimedia card slot interface.
