Publication number: 20240121028Abstract: The present disclosure discloses a data receiving apparatus and a data receiving method having blind deconvolution mechanism. A descrambling circuit descrambles received data according to an antenna assumption and N data position assumptions within a transmission period to generate N groups of soft-bit data. A soft-bit processing circuit retrieves bit position data to determine non-variable bit positions and variable bit positions. N circular buffers of a storage circuit store and superimpose the N groups of soft-bit data corresponding to N data position assumptions in a circular manner to generate N groups of superimposed results and keep the data corresponding to the non-variable bit positions. A post-processing circuit performs de-interleaving and decoding on the N groups of superimposed results to generate N groups of decoded results to perform redundancy check thereon. When one decoded results passes the redundancy check, the soft-bit processing circuit stops performing the blind deconvolution process.Type: ApplicationFiled: June 16, 2023Publication date: April 11, 2024Inventors: FENG-XIANG WANG, MING-YUE YOU, JYUN-WEI PU, JIA-YI ZHUANG

Patent number: 11464450Abstract: A fixed-sensor finger action detecting glove has a glove body, five covering sheets, five fixing bases, five sensors, and five fixing assemblies. A side of the glove body forms a hand back section and five finger back sections. The covering sheet is mounted on the finger back section and forms a passage. The fixing base is made from a flexible material, is mounted through the passage, and has two limiting walls. The sensor is located in the passage between the two limiting walls, preventing the sensor from deviating. The fixing assembly is mounted between an end of the sensor and an end of the finger back section, detachably connects the sensor and the finger back section, and prevents the sensor from moving back and forth. Thus, the fixed-sensor finger action detecting glove is capable of detecting actions of the fingers precisely.Type: GrantFiled: December 28, 2018Date of Patent: October 11, 2022Assignee: REHABOTICS MEDICAL TECHNOLOGY CORP.Inventors: Jian-Jia Huang, Shu-Wei Pu, Tsung-Fu Liu, Pin-Tseng Liu, Li-Wei Cheng
