20150349404 | Antenna System - An antenna system is disclosed. The antenna system includes a printed circuit board, a metallic frame surrounding and electrically connecting with the printed circuit board, a low frequency antenna unit electrically connecting to the metallic frame and an antenna feed, a high frequency antenna unit electrically connecting to the metallic frame and the antenna feed, a ground terminal disposed on the metallic frame for grounding the metallic frame, and an adjusting terminal for being grounded via a matching component for adjusting the low frequency performance of the antenna system. The antenna system enables covering the operational frequency bands of 791 MHz˜960 MHz, and 1710 MHz˜2690 MHz. By virtue of the adjusting terminal, ultra wide low frequency of dual-resonance is accordingly performed. | 12-03-2015 |
20140375866 | Integrated Lens Stack - Disclosed is an integrated lens stack manufactured by dicing a wafer. The integrated lens stack includes an image sensor, at least one lens modules located on the image sensor. Each of the lens modules has a top lens, a bottom lens, and a middle lens between the top lens and the bottom lens, the bottom lens including a first active area and a second active area opposite to the second active area for collecting light, respectively. A chamber is formed between the middle lens and the bottom lens and is a closed room. An area of the first active area is sufficiently smaller than an area of the second active area. | 12-25-2014 |
