Patent number: 11258461Abstract: A data processing device includes decoder circuits, a checker circuit, and a control circuit. The decoder circuits set groups of first sampling points and groups of second sampling points according to an initial transition edge of a first signal, and perform a parallel decoding on the first signal according to the groups of first sampling points and the groups of second sampling points, in order to generate a second signal and a third signal. The checker circuit checks the second signal and the third signal, in order to generate a check result. The control circuit selects at least one of the decoder circuits according to the check result for receiving subsequent data.Type: GrantFiled: September 28, 2020Date of Patent: February 22, 2022Assignee: REALTEK SEMICONDUCTOR CORPORATIONInventors: Yao-Chun Chuang, Hsin-Yun Hu, Ching-Yen Lee, Ming-Jhe Du

Patent number: 8836318Abstract: A proximity electric current sensing device includes a main body, a first and second adjusting components, a first to third sensing units. The main body has a hole for a conducting wire to go through. The first and second adjusting components are disposed on a first and second sides of the main body respectively for adjusting a first and second positions of the conducting wire. The first to third sensing units are disposed on the main body and adjacent to a first to third sides of the conducting wire respectively for sensing a first to third magnetic fluxes of the conducting wire. The processing unit rotates the adjusting components to ensure the third sensing unit is right above the center of the conducting wire according to the first and second magnetic flux, estimates an installation position, and calculates an amount of an electric current according to the third magnetic flux.Type: GrantFiled: December 19, 2011Date of Patent: September 16, 2014Assignee: Industrial Technology Research InstituteInventors: Shih-Hsien Cheng, Ming-Jhe Du, Lien-Yi Cho
