Abstract: Light condensing lens, module, and photoelectric transducing apparatus are disclosed. The lens has a light receiving surface, a bottom surface, and two side surfaces. The side surfaces are obliquely connected with the light receiving surface and the bottom surface. By designing the radian of the light receiving surface, the light streams can be condensed to a predetermined region no matter where the light source is. Additionally, an auxiliary light module is provided for reflecting the light streams to the predetermined region, in order to increase the photoelectric transducing efficiency.

Abstract: A wireless transmission adaptation method and apparatus for converting a wireless signal between a first and second electrical devices are described. The apparatus has a first wireless transmission interface, a second wireless transmission interface and a control unit. The first wireless transmission interface is used for compatibility with a first wireless signal from the first electrical device. The second wireless transmission interface is used for compatibility with a second wireless signal from the second electrical device. The control unit is electrically coupled between the first and second wireless transmission interfaces. The control unit provides the format conversion for the signals transmitted between the first and second wireless transmission interfaces.

Abstract: A curved surface signal pick-up device comprises a rotary disk and graphite brushes. The rotary disk has grid ring on the side thereof. The grid ring have a common portion and transferring portions spaced with equal or unequal distances, each of the transferring portions are arranged alternatively so that the common portion and transferring portions on the rotary disk are arranged on the same radius. Graphite brushes made by dividing an single located element, one end of the graphite brushes are connected on a circuit board for transferring the receiving different signals, while another end of the graphite brushes are contacted with the common portion and the transferring portions of the grid ring.
