Publication number: 20240083269Abstract: A charge coupler with integrated electrical and mechanical disconnect switching can include a first member. A charging coupler can include a first member and a second member. The second member can be coupled at a first end with the first member. A charging coupler can include a first switch disposed at the first member and operable to cause, in response to a movement of the second member to a first angle with the first member that engages the first switch, a charging device to electrically decouple the charging device from a vehicle. A charging coupler can include a second switch disposed at the first member and operable to cause, in response to a movement of the second member to a second angle with the first member that engages the second switch, the charging device to mechanically decouple the charging device from the vehicle.Type: ApplicationFiled: September 14, 2022Publication date: March 14, 2024Inventors: Nasser Noormohammadi, Kevin Sze, Tyler Jay Erikson, Travis Elliot Stewart, Alexander Michael Kwan, Kyle Robert Underhill, Kush Upreti, Ellen Marie Hilgersom, Robin John Moore

Publication number: 20240085174Abstract: Methods and systems for feed-forward of multi-layer and multi-process information using XPS and XRF technologies are disclosed. In an example, a method of thin film characterization includes measuring first XPS and XRF intensity signals for a sample having a first layer above a substrate. The first XPS and XRF intensity signals include information for the first layer and for the substrate. The method also involves determining a thickness of the first layer based on the first XPS and XRF intensity signals. The method also involves combining the information for the first layer and for the substrate to estimate an effective substrate. The method also involves measuring second XPS and XRF intensity signals for a sample having a second layer above the first layer above the substrate. The second XPS and XRF intensity signals include information for the second layer, for the first layer and for the substrate.Type: ApplicationFiled: August 21, 2023Publication date: March 14, 2024Applicant: NOVA MEASURING INSTRUMENTS INC.Inventors: Heath POIS, Wei T LEE, Lawrence BOT, Michael KWAN, Mark KLARE, Charles LARSON

Publication number: 20160055975Abstract: This application includes multiple embodiments related to capacitors. In some embodiments, capacitors are set forth as having terminal leads that extend in parallel and opposing axial directions. The embodiments discussed herein relate to a capacitor module including one or more anodized pellets for providing a charge storage within the capacitor module. The capacitor module can be configured as a surface mounted or non-surface mounted capacitor module. The capacitor module can include an array of anodized pellets arranged in multiple rows or columns of anodized pellets connected by conductive trace included in the capacitor module. In a non-surface mounted embodiment of the capacitor module, the capacitor module can include cathode and anode connections that are exclusively on the side surfaces of the capacitor module.Type: ApplicationFiled: August 19, 2015Publication date: February 25, 2016Inventors: Cesar Lozano Villarreal, Gang Ning, Alexander Michael Kwan

Patent number: 9201030Abstract: A method to determine a distribution profile of an element in a film. The method comprises exciting an electron energy of an element deposited in a first film, obtaining a first spectrum associating with the electron energy, and removing a background spectrum from the first spectrum. Removing the background value generates a processed spectrum. The method further includes matching the processed spectrum to a simulated spectrum with a known simulated distribution profile for the element in a film comparable to the first film. A distribution profile is obtained for the element in the first film based on the matching of the processed spectrum to a simulated spectrum selected from the set of simulated spectra.Type: GrantFiled: November 14, 2014Date of Patent: December 1, 2015Assignee: ReVera, IncorporatedInventors: Paola deCecco, Bruno Schueler, David Reed, Michael Kwan, David Stephen Ballance

Patent number: 9095076Abstract: An electronic device may have a housing in which electronic components are mounted. The electronic components may be mounted to a substrate such as a printed circuit board. A heat sink structure may dissipate heat generated by the electronic components. The housing may have a housing wall that is separated from the heat sink structure by an air gap. The housing wall may have integral support structures. Each of the support structures may have an inwardly protruding portion that protrudes through a corresponding opening in the heat sink structure. The protruding portions may each have a longitudinal axis and a cylindrical cavity that lies along the longitudinal axis. Each of the support structures may have fins that extend radially outward from the longitudinal axis.Type: GrantFiled: May 6, 2014Date of Patent: July 28, 2015Assignee: Apple Inc.Inventors: Vinh Diep, Chiew-Siang Goh, Doug Heirich, Alexander Michael Kwan, Cesar Lozano Villarreal
