Publication number: 20240120247Abstract: A method of manufacturing a semiconductor package is provided, with an integrated heatsink and electrical connection feature. The semiconductor die can be attached to the terminal using eutectic bonding, preferably CuSn eutectic, Ag containing adhesives or Ag sintering material. These bondings are lead (Pb) free connection methods, which make the finished semiconductor package RoHS compliant (restriction of hazardous materials).Type: ApplicationFiled: October 6, 2023Publication date: April 11, 2024Applicant: NEXPERIA B.V.Inventors: Regnerus Hermannus Poelma, Wai Man Wong, Tim Böttcher, Hans-Juergen Funke, Jannik Entringer, Yuet Keung Cheung, Chun Ning Chan

Publication number: 20220267861Abstract: Systems, methods, and apparatuses can determine and use methylation profiles of various tissues and samples. Examples are provided. A methylation profile can be deduced for fetal/tumor tissue based on a comparison of plasma methylation (or other sample with cell-free DNA) to a methylation profile of the mother/patient. A methylation profile can be determined for fetal/tumor tissue using tissue-specific alleles to identify DNA from the fetus/tumor when the sample has a mixture of DNA. A methylation profile can be used to determine copy number variations in genome of a fetus/tumor. Methylation markers for a fetus have been identified via various techniques. The methylation profile can be determined by determining a size parameter of a size distribution of DNA fragments, where reference values for the size parameter can be used to determine methylation levels. Additionally, a methylation level can be used to determine a level of cancer.Type: ApplicationFiled: March 10, 2022Publication date: August 25, 2022Inventors: Yuk-Ming Dennis Lo, Rossa Wai Kwun Chiu, Kwan Chee Chan, Miu Fan Lun, Wai Man Chan, Peiyong Jiang

Patent number: 9451951Abstract: A delivery device (suture passer or suture snare) that may be used in both open and endoscopic surgical procedures. The delivery device is designed with an internal member terminating in a snare and a retractable outer sheath (sleeve). The device is passed through tissue, and the outer sheath is retracted (moved back), allowing the snare to open. The suture is captured by the snare, and the outer sheath is then released so that it returns to its distal position, closing the snare and securing the captured suture. Since the snare is exposed by retracting the outer sheath (sleeve), rather than advancing the snare, the space requirement for the device is reduced, as is the possibility that the snare will undesirably contact sensitive tissue.Type: GrantFiled: November 6, 2013Date of Patent: September 27, 2016Assignee: Arthrex, Inc.Inventors: Derek C.

Patent number: 9317626Abstract: The present invention discloses a method for combinatorial layout design, in particular family mold layout design, using a computer. The method starts with receiving design specific parameters and information about molding parts from user. A Genetic Algorithm module is then invoked to generate a population of layout designs which satisfies the design specific parameters. The Genetic Algorithm module first automatically generates a population of specially designed chromosome with three interdependent sessions. Crossover, mutation and replacement operation are applied on the population subsequently to evolve such towards a more optimal population over successive generations. In each generation step, a Genotype-Phenotype mapping module is utilized to decode the chromosome to corresponding layout design for fitness evaluation. A system for combinatorial layout design automation and optimization using this evolutionary design approach is also disclosed in the present invention.Type: GrantFiled: November 15, 2012Date of Patent: April 19, 2016Inventor: Wai Man Chan
