Publication number: 20240139900Abstract: A chemical mechanical polishing apparatus has a platen to support a polishing pad, a carrier head comprising a rigid housing and configured to hold a surface of a substrate against the polishing pad, a motor to generate relative motion between the platen and the carrier head so as to polish the substrate, an in-situ carrier head monitoring system including a sensor positioned to interact with the housing and to detect vibrational motion of the housing and generate signals based on the detected vibrational motion, and a controller. The controller is configured to generate a value for a carrier head status parameter based on received signals from the in-situ carrier head monitoring system, and change a polishing parameter or generate an alert based on the carrier head status parameter.Type: ApplicationFiled: January 24, 2023Publication date: May 2, 2024Inventors: Jeonghoon Oh, Jianshe Tang, Steven M. Zuniga, Brian J. Brown, Andrew J. Nagengast, Derek R. Witty, Rushabhkumar Desai, Shih-Haur Shen, Haosheng Wu, Yufei Hu

Patent number: 7133519Abstract: A system and method for host signaling processing that allows multiple SS7 applications to have visibility to the SS7 network traffic and the ability to control the SS7 network traffic. The applications residing on the platform have visibility to the SS7 traffic flowing through the Intelligent Communications Point (ICP) Platform, ability to control and modify the traffic and the ability to inject new SS7 traffic onto the SS7 links. The ICP platform will provide basic services that applications can use including Logging Data, Process Events, Inter Process Communication Services, and an interface to the Intelligent Communications Manager which provides a graphical user interface to manage the ICP. In addition to these services, the ICP Platform will provide basic traffic metering and measurement, bookkeeping statistics, and a failsafe mechanism for the SS7 links.Type: GrantFiled: November 14, 2003Date of Patent: November 7, 2006Assignee: Sevis Systems, Inc.Inventors: Mike Ashdown, Hu Shen, Steve Lynchard, Robert Winslow

Patent number: 6850482Abstract: A system and method for intelligently redirecting data traffic from a Public Switched Telephone Network (PSTN) to a data network. The system can include: an intelligent communications platform connected between a switch and a Signaling System 7 (SS7) network to intercept SS7 messages between the switch and the SS7 network; and a communications control module connected to the intelligent communications platform via a Transmission Control Protocol/Internet Protocol (TCP/IP) link, the communications control module for providing management and communications to the ICP and providing access to the management and communication for a plurality of subscribers. The ICP can include an SS7 I/O card for processing SS7 messages and a CPU card for processing ISUP and TCAP. The communications control module can include: instructions for receiving messages from other ICPs for updated information on congestion on certain routes.Type: GrantFiled: March 28, 2000Date of Patent: February 1, 2005Assignee: Sevis Systems, Inc.Inventors: Mike Ashdown, Hu Shen, Steve Lynchard

Patent number: 6226373Abstract: An ISP 10 provides enhanced features compatible with non-AIN switches to allow service providers to provide customers with features such as voice prompting, DTMF number collection, fax on demand and similar features. In one embodiment, the ISP can also be configured as an IP. Enhanced features can be accomplished using the ISP, such as advanced routing of long distance calls based on ANI, authorization codes, type of call, time of day, origination of call and destination of call.Type: GrantFiled: July 1, 1998Date of Patent: May 1, 2001Assignee: Alcatel USA Sourcing, L.P.Inventors: Yao T. Zhu, Daniel Luu, Thomas W. Rekieta, Hu Shen
