Patent number: 11047794Abstract: A system and method that improves and enhances the quality of step-scan Fourier Transform Infrared spectroscopy data. The system and method enables the removal of dark voltage with greater accuracy, provides access to previously unobtainable IR spectral information data which is amplified by the disclosed system and method. The system and method removes dark interferogram voltage from an interferogram of interest obtained during nanosecond or microsecond step-scan measurement. The system and method includes a programmable high gain setting to amplify both signal and noise into the analog-to-digital quantization range to allow signal averaging for obtaining additional bits of resolution. The system and method also accounts for and corrects intrinsic offset voltages introduced by the electronics of the disclosed system.Type: GrantFiled: March 6, 2018Date of Patent: June 29, 2021Assignee: The Board of Regents for Oklahoma State UniversityInventors: Chriswell G.

Publication number: 20140197080Abstract: A sorting apparatus for sorting screws includes a first restricting piece, a second restricting piece, and a diversion block. A first pathway is defined between the first restricting piece and the second restricting piece. A second pathway is defined between the first restricting piece and the diversion block. A fourth pathway is defined between the second restricting piece and the diversion block. The first blocking piece is located in the second pathway adjacent to the first pathway. The first blocking piece blocks a long screw to prevent the long screw from sliding from the first pathway to the second pathway and guides the long screw to slide from the first pathway to the fourth pathway. The first blocking piece lets a short screw slide from the first pathway to the second pathway.Type: ApplicationFiled: October 11, 2013Publication date: July 17, 2014Applicants: HON HAI PRECISION INDUSTRY CO., LTD., HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTDInventors: CHIH-HAO YANG, XIANG-KUN ZENG, CHENG HAO, RUN LONG
