Patent number: 11924444Abstract: Method and apparatus for constrained de-blocking filter are disclosed. One method receives input data related to a current block in a current picture at a video encoder side or a video bitstream corresponding to compressed data including the current block in the current picture at a video decoder side, and determines a first boundary associated with the current block, wherein the first boundary corresponds to one vertical boundary or one horizontal boundary of the current block. The method then applies de-blocking process to a reconstructed current block corresponding to the current block to result in a filtered-reconstructed current block, using a plurality of first reference samples at a same side of the first boundary, and replaces a first set of the first reference samples by one or more padding values. The method then generates a filtered decoded picture including the filtered-reconstructed current block.Type: GrantFiled: April 11, 2022Date of Patent: March 5, 2024Assignee: HFI INNOVATION INC.Inventors: Chia-Ming Tsai, Chih-Wei Hsu, Ching-Yeh Chen, Tzu-Der Chuang, Yu-Wen Huang

Patent number: 10265485Abstract: A medication concentration detecting device includes a medicine container, a three-way pipe, a light emitting member, a first light receiver and a processor. The medicine container has a chamber configured for accommodating nebulized medicine. The three-way pipe has a passageway connected to the chamber for the nebulized medicine to flow along the passageway. The light emitting member is disposed on the three-way pipe and configured for emitting a light beam toward the passageway. The first light receiver is disposed on the three-way pipe and configured for receiving the light beam and outputting a luminous flux signal. The processor is connected to the first light receiver and configured for calculating a luminous flux reference value according to the luminous flux signal. The luminous flux reference value is used for determining whether outputs a low nebulized medicine concentration warning.Type: GrantFiled: December 14, 2015Date of Patent: April 23, 2019Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Yio-Wha Shau, Ma-Li Wang, Tzu-Wen Tsai, Tian-Yuan Chen, Hsin-Hsiang Lo, Chun-Chuan Lin, Shih-Bin Luo
