Publication number: 20240097662Abstract: An integrated circuit includes an upper threshold circuit configured to set a logic level of a first enabling signal, a lower threshold circuit configured to set a logic level of a second enabling signal, and a control circuit configured to change an output voltage signal in response to a condition that the logic level of the first enabling signal and the logic level of the second enabling signal are changed consecutively. In the control circuit, a first switch is electrically connected to a second switch at a buffer output node. The control circuit includes a regenerative circuit configured to maintain the output voltage signal at the buffer output node while each of the first switch and the second switch is at a disconnected state.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Inventors: Yu-Kai TSAI, Chia-Hui CHEN, Chia-Jung CHANG

Patent number: 8455254Abstract: The invention discloses a method of accelerating osteogenic differentiation and a composition thereof. The method comprises a step of adding type II collagen into stem/progenitor cells or osteoblasts to accelerate the osteogenic differentiation of the added cells, and the composition comprises type II collagen, and stem/progenitor cells or osteoblasts. Type II collagen can accelerate osteogenesis of mesenchymal stem cells (MSCs) much faster than does type I collagen. The said composition is effective to facilitate bone repair upon introduction of the composition into various osseous defects.Type: GrantFiled: April 22, 2010Date of Patent: June 4, 2013Assignee: Taipei Medical UniversityInventors: Yu-Hui Tsai, Li-Hsuan Chiu

Publication number: 20110262486Abstract: The invention discloses a bone implant and a manufacturing method thereof. The manufacturing method of the bone implant comprises a step of coating or mixing type II collagen with at least one porous bone material comprising metals, bio-ceramics, natural biopolymers and synthetic polymers. Another manufacturing method of the bone implant comprises the steps of loading type II collagen with or without at least one porous bone material in a container, and lyophilizing the type II collagen to generate a type II collagen sponge construct with or without the porous bone material as the bone material. The manufactured bone implants are effective, with or without loading cells having differentiation tendency towards osteogenesis, to facilitate bone repair upon introduction of the bone implant into various osseous defects.Type: ApplicationFiled: April 22, 2010Publication date: October 27, 2011Applicant: TAIPEI MEDICAL UNIVERSITYInventors: Yu-Hui Tsai, Li-Hsuan Chiu, Wen-Fu Lai, Shih-Ching Chen
