Patent number: 7437848Abstract: A firearm aiming and photographing compound apparatus. A digital sight is disposed on a firearm body and includes an image processing module and a receiver electrically connected thereto. A remote-control transmitter is connected to the firearm body, emitting a signal. The receiver receives the signal, actuating the image processing module.Type: GrantFiled: July 11, 2006Date of Patent: October 21, 2008Assignee: Asia Optical Co., Inc.Inventor: Chia-Chun Chang

Publication number: 20080062514Abstract: A digital telescopic sight includes an objective lens group (202), a light collecting lens (204), an erecting lens group (206), an eyepiece lens group (212), a semi-reflecting mirror (208) and an image sensor (210). The incident exterior light rays are sequentially transmitted through the objective lens group, the light collecting lens and the erecting lens group, and then incident onto the semi-reflecting mirror. The semi-reflecting mirror reflects a portion of the light rays onto the image sensor, and transmits the remaining primary light rays to the eyepiece lens group for enabling the user to view the image. The image sensor receives the reflected portion of the light rays, converts it into an electrical signal, and finally transmits the electrical signal to a digital signal processor for further image signal processing.Type: ApplicationFiled: January 31, 2007Publication date: March 13, 2008Applicant: Asia Optical Co., Inc.Inventors: Chia-Chun Chang, Chen-Yeh Lin

Patent number: 7222432Abstract: A method of assembling a reticle module comprising a first element and a second element is provided. The method includes the following steps. First, a collimated beam of light shines on a first reticle of the first member and a second reticle of the second member to project an image of the first reticle and an image of the second reticle onto a screen. Thereafter, the projected image of the first reticle of the first element and the projected image of the second reticle of the second element are adjusted to align with each other. Then, the relative position between first and the second element is fixed. The method speeds up the process of assembling a reticle module and ensures both constituent reticles aligned in the same viewing direction.Type: GrantFiled: December 1, 2004Date of Patent: May 29, 2007Assignee: Asia Optical Co., Inc.Inventors: Shih-Yu Pai, Chia-Chun Chang

Publication number: 20060038971Abstract: A dual reticle device comprising a ring structure, a first reticle and a second reticle is provided. Four positioning grooves parallel to the axis of the ring structure are formed on the external side surface of the ring. The first reticle and the second reticle are disposed on a first ring end-surface and a second ring end-surface of the ring structure respectively. In the process of assembling the dual reticle device, the positioning grooves position the first and the second reticle on the first and second ring end-surface of the ring structure. Therefore, the first reticle and the second reticle coincide with each other in the axial direction of the ring structure so that the dual reticle device can serve as a tool for improving the accuracy of aiming at a target object set at a distance.Type: ApplicationFiled: December 21, 2004Publication date: February 23, 2006Inventors: Shang-Yung Liang, Chia-Chun Chang
