Patent number: 11967582Abstract: A multi-chip device includes a first material within a substrate. The first material has a first coefficient of thermal expansion different than a second coefficient of thermal expansion of the substrate. A first chip overlies a first portion of the first material and a first portion of the substrate. A second chip overlies a second portion of the first material and a second portion of the substrate. The first material is between the first portion of the substrate and the second portion of the substrate.Type: GrantFiled: April 24, 2023Date of Patent: April 23, 2024Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LIMITEDInventors: Chin-Hua Wang, Po-Chen Lai, Shu-Shen Yeh, Tsung-Yen Lee, Po-Yao Lin, Shin-Puu Jeng

Publication number: 20240120294Abstract: A chip package includes a substrate, a semiconductor chip, and a thermal conductive structure. The chip package includes a first and a second support structures below the thermal conductive structure. The first and the second support structures connect the substrate and corners of the thermal conductive structure. The thermal conductive structure has a side edge connecting the first and the second support structures. The first and the second support structures and the side edge together define of an opening exposing a space surrounding the semiconductor chip. The first and the second support structures are disposed along a side of the substrate. The first support structure is laterally separated from the side of the substrate by a first lateral distance. The side edge of the thermal conductive structure is laterally separated from the side of the substrate by a second lateral distance different than the first lateral distance.Type: ApplicationFiled: December 21, 2023Publication date: April 11, 2024Inventors: Shu-Shen YEH, Chin-Hua WANG, Kuang-Chun LEE, Po-Yao LIN, Shyue-Ter LEU, Shin-Puu JENG

Publication number: 20220008093Abstract: An self-actuating grasping device and corresponding method of using the grasping device for retrieving a foreign object from a location in a patient's body. The grasping device has a handle with a self-actuating mechanism, an actuator on the handle coupled to an actuator wire, an elongated shaft member extending distally from the handle with the actuation wire coaxially disposed therein and opposing jaws at a distal end of the elongated shaft member that are coupled to the actuation wire and pivot between open and closed configurations. The self-actuating mechanism has a bias that imparts a closing force to the opposing jaws through the actuation wire. Actuation of the actuator is configured to impart an opening force to the opposing jaws through the actuation wire.Type: ApplicationFiled: July 6, 2021Publication date: January 13, 2022Applicant: Prodeon Medical CorporationInventors: Jimmy Jen, Kenneth Chih-Ping Chang, Craig Purdy, Gary Daniel Zaretzka, Po-Hua Lee

Patent number: 10327761Abstract: Systems are provided for delivering a suture to close a surgical opening. An elongated deployment member may have at its distal end a retracted counterforce member. The counterforce member may be inserted into the surgical opening and deployed to resist being withdrawn from the opening. A compression member may be slid down the elongated member to compress the tissue to be sutured against the counterforce member. Suture passers loaded with suture ends may be passed through needle tubes within the elongated member to emerge from the elongated member and pierce the tissue to be sutured, then deposit the suture ends with a suture catcher. The suture passers may be withdrawn, leaving the suture ends. The suture catcher may be retracted, retaining the suture ends and the device—elongated member, retracted suture catcher, and retained suture end—may be withdrawn from the surgical opening. The suture may then be completed.Type: GrantFiled: August 11, 2016Date of Patent: June 25, 2019Assignee: Medeon Biodesign, Inc.Inventors: Shih-Wei Ho, Wei-Min Cheng, Hsiao-Wei Tang, I-Ching Wu, Eric Y.

Patent number: 10011722Abstract: Methods and systems for producing warm foam mix asphalt are disclosed. In some embodiments, the methods include the following: injecting an ethanol additive into asphalt binder having a temperature below the auto ignition point of ethanol to form a foamed asphalt stream; adding the foamed asphalt stream to a mixing zone; adding at least one of aggregate and reclaimed asphalt pavement to the mixing zone; adding a foaming agent to the mixing chamber; heating at least one of the mixing zone and the at least one of aggregate and reclaimed asphalt pavement; mixing the foamed asphalt stream and the at least one of aggregate and reclaimed asphalt pavement to form a warm foam mix asphalt; collecting emissions from the mixing zone, the emissions including ethanol vapors; and recycling the emissions to the mixing zone.Type: GrantFiled: June 18, 2014Date of Patent: July 3, 2018Assignee: The Trustees of Columbia University in the City of New YorkInventors: Huiming Yin, Po-Hua Lee, Vincent Nasri, Luis Arias
