  • Publication number: 20110168762
    Abstract: A soldering iron tip is used for heating a solder bar during a soldering operation so as to solder a workpiece. An end surface of the soldering iron tip has a guide hole, and the guide hole forms a channel in the soldering iron tip. Meanwhile, a side surface of the soldering iron tip has a through hole in communication with the channel. When the soldering operation is performed, relative positions of the guide hole and the workpiece overlap each other. After the solder bar is made to pass through the through hole and heated inside the channel, the molten solder bar flows along the channel to reach the workpiece via the guide hole, thereby completing the soldering operation.

  • Publication number: 20100004000
    Abstract: A method for automatically changing incoming call alert profile upon the current location, implements on a GPS-functioned portable communication device. The method continually obtains a location coordinate, compares the location coordinate with a comparison list to match an incoming call alert profile for the portable communication device's current incoming call alert profile. Thus, wherever the portable communication device moves to, a reaction will be presented automatically according to the current incoming call alert profile when an incoming call comes.
