  • Publication number: 20090153419
    Abstract: An antenna structure for portable electronic device includes an antenna and an electrical connection element. The portable electronic device includes a main body, a slotted section, a shaft, and a slot cover. The slot cover is coupled to the main body via the shaft, and the slot cover is located on the slotted section. The antenna is disposed on the slot cover, and the electrical connection element is coupled to the shaft and a printed circuit board mounted in the main body, so that the antenna is electrically coupled via the electrical connection element to the printed circuit board. Since the antenna disposed on the slot cover is not parallel with the printed circuit board, a clearance distance required between the antenna and the printed circuit board can be reduced to enable reduction of a volume of the portable electronic device.

  • Patent number: 7540982
    Abstract: A molding lens with indentations for measuring eccentricity and a method for measuring eccentricity thereof are disclosed. At least one indentation concentric with an optical surface is respectively disposed on a front plane and a rear plane of the molding lens on area outside the optical surface while the indentation is observed by means of a measuring microscope. Moreover, the eccentricity of the molding lens is detected by eccentricity test function of the measuring microscope and the eccentric direction is defined so as to modify the lens mould and replace conventional eccentricity test that uses a transmission eccentric scale indicator in combination with a jig. Thus the cost of test equipment is reduced, test procedure is simplified and efficiency of mould modification is improved. Therefore, it's more convenient to manage manufacturing of the lens.
