Abstract: A concentrating photovoltaic (CPV) apparatus includes at least one lens unit, at least one solar cell chip unit, and a frame structure. The frame structure includes at least two opposite main walls, a plurality of upper and lower support bars extended between and connected to the two main walls, and two sidewalls. The main walls are each provided with at a predetermined position with at least one air opening and at two lateral ends with a first and a second connecting portion. Two ends of the upper and lower support bars are connected to the first and the second connecting portions, allowing the lens unit and the solar cell chip unit to be supported on and fixed to the upper and the lower support bars, respectively.

Abstract: A method for instant communication through the Internet is provided. The method provides the users to instantly communicate with the online registered members through a web page connection without having to install software and register an account. In addition, the method provides Internet service providers with a purchase channel, such that the customer can communicate with the client service representatives instantly. Accordingly, the purpose of enhancing the convenience of instant Internet communication and Internet service is achieved.

Abstract: The executing program method is applied to a Bluetooth dongle using a universal serial bus (USB) as its transmission interface. When the Bluetooth dongle is plugged in an electronic device, the electronic device will automatically detect the Bluetooth dongle. An application which is stored in a storage unit of the Bluetooth dongle is activated, and the Bluetooth dongle is also activated to link a Bluetooth device. The cache files produced by the application are pointed to store in the storage unit of the Bluetooth dongle. In addition, an auto-detecting program is executed to detect whether the Bluetooth dongle is removed or not every certain period. If the Bluetooth dongle was removed, the link from the Bluetooth dongle to the Bluetooth device will be terminated. The cache files in the Bluetooth dongle will be cleared. Finally, the application and the auto-detecting program are closed.

Abstract: A lens for chromatic aberration compensation is provided. The lens includes a lens body and a plurality of color filter films. The lens body has a light incident plane, a light exit plane and an optical axis. The light incident plane and/or the light exit plane comprises a plurality of discrete area, wherein the area comprises, for example but not limited to, a plurality of annular areas, fan-shaped areas, or polygon areas. The color filter films are disposed over the areas of the lens body respectively, and comprise red color filter films, green color filter films or blue color filter films. Accordingly, the lens for chromatic aberration compensation of the invention can eliminate the aberration effectively.

Abstract: A method of determining tag identifications is discloses. The method comprises: providing an index signal; receiving a responsive signal generated from tag matching the index signal; obtaining an identification code corresponding to the responsive signal; reader sending an acknowledgement and waiting for tag to respond a returned-acknowledgement. A searching process is repeated at the current node after a tag responsive signal is received to prevent signal suppression errors.

Abstract: An auto-registration method for scanners. The method includes implanting a serial number into a scanner. When the scanner operates, the serial number is automatically retrieved. If the scanner is linked to a network, the serial number is transmitted to a documentary file inside a registration center through the net. On the other hand, if the scanner is not connected to a network, other data transmission means can be used to carry out the registration. According to the registered information, various post-registration services are executed.
