Publication number: 20240136160Abstract: Embodiments of the present disclosure generally relate to methods and apparatus for measuring and controlling local impedances at a substrate support in a plasma processing chamber during processing of a substrate. A substrate support includes a plurality of substrate support pins wherein the radio frequency voltage, current and phase of each of the plurality of substrate support pins are measured and impedances of the support pins are adjusted in real time. Each of the substrate support pins is coupled to an associated adjustable impedance circuit that may be remotely controlled. In one embodiment a variable capacitor is used to adjust the impedance of the impedance circuit coupled to the associated substrate support pin and may be remotely adjusted with a stepper motor.Type: ApplicationFiled: October 20, 2022Publication date: April 25, 2024Inventors: Zheng John YE, Andrew C. LAM, Zeqiong ZHAO, Jianhua ZHOU, Hshiang AN, Suhail ANWAR, Yoshitake NAKAJIMA, Fu-ting CHANG

Patent number: 10187430Abstract: In some implementations, a network daemon can manage access to a mobile device's network interface. The network daemon (e.g., network connection managing process) can monitor the condition of the mobile device's network connection on one or more interfaces. The network daemon can monitor many conditions on the mobile device. The network daemon can receive background networking requests from network clients (e.g., processes, applications) that specify criteria for initiating a network connection. The network daemon can then smartly manage network connections taking into account network conditions, mobile device conditions and/or client criteria received in the client request. This can help reduce battery life impact, memory usage, likelihood of call drops, data usage cost, and load on network operators.Type: GrantFiled: June 7, 2013Date of Patent: January 22, 2019Assignee: Apple Inc.Inventors: Amit K. Vyas, Joshua V. Graessley, John Iarocci, Darren Litzinger, Andrew C. Lam, Ray Ling Chang, Steven Douglas Parker, Justin Wood, Matthew Scott Klahn, Daniel B. Pollack

Patent number: 6630165Abstract: Dosage forms and methods for providing sustained release of reboxetine are provided. The sustained release dosage forms provide therapeutically effective average steady-state plasma reboxetine concentrations when administered once per day. This once-a-day dosing regimen results in only one peak plasma reboxetine concentration occurrence in each 24 hour period. In addition, the peak plasma reboxetine concentration occurs at a later time following dose administration and exhibits a lesser magnitude than the peak plasma reboxetine concentration that occurs following administration of reboxetine in an immediate-release dosage form.Type: GrantFiled: February 28, 2002Date of Patent: October 7, 2003Assignee: Alza CorporationInventors: Sylvia L.
