Abstract: A wireless handset includes: a Bluetooth RF module for performing wireless communication with a Voice over Internet Protocol (VoIP) communication device having Bluetooth communication functionality; a processing circuit, coupled to the Bluetooth RF module, for remotely controlling a VoIP software application, which is embedded in the VoIP communication device, through the Bluetooth RF module according to Bluetooth Human Interface Device specifications; and an audio input/output module, coupled to the processing circuit, for receiving audio waves to input an audio signal into the processing circuit, and/or outputting audio waves; wherein the wireless handset provides web phone communication functionality by utilizing the VoIP software application.

Abstract: The present invention discloses a light-shielding heat-dissipating mask for a projector. The projector has a light source, a fan, and an air vent. The light-shielding heat-dissipating mask comprises a plurality of metal sheets which are positioned at the air vent for dissipating the heat generated by the light source and decreasing the possibility of the light emitted form the light source escaping out of the air vent.

Abstract: An electronic apparatus includes a casing, a light source housed in the casing, and a heat dissipation device positioned between the casing and the light source. The casing is formed with a lead angle on its corner to create an inclined surface. The heat dissipation device has a first and a second end surfaces opposite to each other and a sidewall connected between them. The sidewall of the fan frame neighbors the inclined surface and has a slanting direction substantially paralleled to the inclined surface.

Abstract: A method for treating waste printing circuit boards with molten mixture of inorganic salts comprising actions of: (1) putting the circuit boards into the molten inorganic salts contained in a treating furnace; (2) crushing and stirring for copper foil of the circuit boards to be separated therefrom; (3) further stirring to separate the foil from the plastic and the glass fiber of the circuit boards; (4) scraping the floating residues of the plastic and the glass fiber on upper surface of the molten inorganic salts with a floating residues scraping device; (5) collecting the carbonized plastic residues and the glass fiber; (6) converting waste gas produced in the process into an unharmful and stable one; and (7) removing the copper foil by a certain amount regularly with a removing device.

Abstract: A method and a device for treating waste printed circuit boards with molten tin include process of throwing printed circuit boards into a molten tin bath in treating furnace, letting the boards proceed crashing, stirring and carbonizing treatment for separating copper foil, thermosetting plastic and glass fiber. Then these three kinds of materials are respectively separated from each other by taking advantage of their different specific gravity and collected in separate tanks to recover copper and other metals from the waste printed circuit boards.

Abstract: The present invention comprises an apparatus for processing liquid or gas waste. The apparatus includes a high temperature plasma means for generating a high temperature in a plasma torch area. The apparatus further includes a jetting means for transporting and jetting the liquid or gas waste to the high temperature plasma torch area directly wherein a high temperature treatment of the waste is performed.
