Patent number: 12249177Abstract: Provided is a recognition method of 3D vein pattern including the following steps. A plurality of first light beams are emitted by a recognition device to a wrist of a user. A plurality of first reflected light beams from the wrist are received by the recognition device to form a first 3D vein pattern of the wrist. Differences between the first 3D vein pattern and a wrist vein pattern of a database are compared to identify an identity or a gesture of the user. A recognition device of 3D vein pattern is also provided.Type: GrantFiled: December 21, 2021Date of Patent: March 11, 2025Assignee: Industrial Technology Research InstituteInventors: Wei-Cheng Chao, Chia-Hsin Chao, Li-Chi Su, Chi-Chin Yang, Cheng-Jhih Luo

Patent number: 11829731Abstract: A modular multiplication circuit includes a main operation circuit, a look-up table, and an addition unit. The main operation circuit updates a sum value and a carry value according to 2iA corresponding to a first operation value A and m bits of a second operation value B currently under operation, m is a positive integer, i is from 0 to m?1. The look-up table records values related to a modulus, and selects one of the values as a look-up table output value according to the sum value. The addition unit updates the sum value and the carry value according to the look-up table output value and outputs the updated sum value and the updated carry value to the main operation circuit. The modular multiplication circuit updates the sum value and the carry value in a recursive manner by using m different bits of the second operation value B.Type: GrantFiled: December 27, 2021Date of Patent: November 28, 2023Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Chia-Hsiang Yang, Liang-Hsin Lin, Yu-Ling Kang, Li-Chi Su
