Publication number: 20210342767Abstract: An externally-connected shop floor control (SFC) system comprising M shop floor control (SFC) devices is disclosed. By letting each of the M SFC devices be electrically connected between one test machine and one information read-out device, the SFC system is successfully implemented into a production line. Therefore, each of the M SFC devices is adopted to achieve a re-verification of pass record for a test object that is transferred from a previous-stage test machine, and is also adopted for collecting related test data of the test object transferred from a current-stage test machine. As such, the SFC system can be easily implemented into any one type of production line, so as to assist the manager of the production line in data collection, station passing control, manufacturing reports, and control of production efficiency and yield, without spending much cost of human resources and software/firmware developing.Type: ApplicationFiled: July 24, 2020Publication date: November 4, 2021Inventors: SHIH-CHIEH HSU, WEI-LUNG HUANG, PEI-MING CHANG, PAO-CHUNG CHAO, TZU-CHI TSENG, CHIA-FENG LEE

Publication number: 20210063239Abstract: Disclosures of the present invention describe a method for calibrating laser power. During a laser power calibration of a laser optics product, reference intensity data and reference power data are adopted for generating a reference trend line with a R2 value that is equal to 1. As such, real intensity data that have a residual value smaller than a threshold value are adopted for generating a first trend line in combination with real power data. Moreover, the real intensity data that have a residual value greater than the threshold value are utilized for generating a second trend line in combination with corresponding real power data. Consequently, under an assistance of a predict trend line constituted by the first trend line and the second trend line, the laser power calibration is therefore completed after the laser optics product successively emits a laser beam by a few times.Type: ApplicationFiled: October 22, 2019Publication date: March 4, 2021Inventors: SHIH-CHIEH HSU, WEI-LUNG HUANG, PEI-MING CHANG, PAO-CHUNG CHAO, WEN-CHIH SHEN

Publication number: 20210026461Abstract: Disclosures of the present invention describe an independent inputting device with self-learning function. During a user inputting a vocabulary word and/or a sentence, this independent inputting device can forecast what vocabulary word is that the user desires to input in case of a number of inputted letters of the vocabulary word reaching a threshold integer (?N). Consequently, this independent inputting device automatically completes the inputting of those un-inputted letters of the vocabulary word, such that the user does no longer continue the inputting of those un-inputted letters of the vocabulary word. As such, when the user adopts one input method to edit a program code, write an article or a letter, or make statistical forms, inputting speed of the typed vocabulary words can be apparently increased by this independent inputting device, thereby largely enhancing the user's work efficiency.Type: ApplicationFiled: October 3, 2019Publication date: January 28, 2021Inventors: SHIH-CHIEH HSU, WEN-CHIH SHEN, WEI-LUNG HUANG, PEI-MING CHANG, PAO-CHUNG CHAO
