Publication number: 20240080654Abstract: This application sets forth techniques for dynamically managing a provisioning electronic subscriber identity module (eSIM) for a wireless device. A provisioning eSIM is installed in the wireless device to provide a limited functionality connectivity option for essential services, such as device activation and user eSIM provisioning. To reduce signaling load on a network and to conserve wireless device battery power, the provisioning eSIM is reconfigured between an inactive state and an active state dynamically based on user actions and system requirements.Type: ApplicationFiled: August 14, 2023Publication date: March 7, 2024Inventors: Li LI, Abishek Kumar VAIDYANATHAN, Kanuganti Rajeswar REDDY, Keizo MARUI, Mohanasundaram KATTAVOOR SIVAKUMAR, Rohan WADAGERI, Zexing SHI, Raj S.

Publication number: 20150381118Abstract: Methods and devices for eliminating a systematic imbalance and reducing variations in circuit parameters for a high gain amplifies. A bias generator having a copy of an actual amplifier branch and an already generated bias voltage can be added to the amplifier to generate a bias voltage for a final current source at a current summing node so as to eliminate systematic imbalance in the bias current. A high impedance node can be wired in the bias generator such that all devices in the bias generator are in saturation across, for example, PVT (Process, Voltage and Temperature) corners in order to minimize tracking errors. A degeneration transistor similar to a differential pair element can be split into two equal halves.Type: ApplicationFiled: June 27, 2014Publication date: December 31, 2015Inventors: Shyam S. Sivakumar, Hiep T. Pham, Bradley Wright

Patent number: 8963577Abstract: A termination impedance apparatus includes a variable pull-up resistor, a variable pull-down resistor, and a small-signal calibration circuit. The variable pull-up resistor is coupled between a first power supply voltage terminal and an output terminal. The variable pull-down resistor is coupled between the output terminal and a second power supply voltage terminal. The small-signal calibration circuit is for calibrating the variable pull-up resistor and the variable pull-down resistor to achieve a desired small-signal impedance.Type: GrantFiled: April 24, 2013Date of Patent: February 24, 2015Assignee: Advanced Micro Devices, Inc.Inventors: Warren R. Anderson, Shyam S. Sivakumar, Austen J. Hypher

Patent number: 7774219Abstract: A method for executing a schedule in a workflow application is provided. The method includes selectively storing a schedule state to a storage medium based on a latency attribute associated with the schedule. Also provided is a method of executing a workflow application comprising long running transactions. This method includes selectively storing a schedule state to a storage medium based on a latency attribute associated with the schedule, and selectively compensating certain actions within the schedule according to a compensation parameter associated with an action, based on failure or abortion of another action within the schedule. In addition, there is provided a method of executing a schedule comprising selectively compensating certain actions or transactions within the schedule according to a compensation parameter associated with an action or transaction, based on failure or abortion of another action or transaction within the schedule.Type: GrantFiled: July 21, 2000Date of Patent: August 10, 2010Assignee: Microsoft CorporationInventors: Gregory Lucius Meredith, Amit Mital, Anthony Andrews, Arunchallam S. Sivakumar, Donald J. McCrady, Patrick J. Helland, Bimal Mehta

Patent number: 7757213Abstract: A system for managing an application set is disclosed. The system includes a wrapper that designates a component as belonging to the application set and an interface that provides access to the component. The system also includes a control module that uses the interface to manage the component. Methods of using the system are also provided.Type: GrantFiled: May 18, 2005Date of Patent: July 13, 2010Assignee: Microsoft CorporationInventors: Eddie Fusaro, Vladimir Pogrebinsky, Arunachallam S.

Patent number: 7487433Abstract: The subject invention provides a system and/or a method that facilitates error detection and correction associated with content-based routing. A routing system can include an analysis component that determines a received message is associated with an error. An error report generating component can append error-related metadata to the received message to create an error report message. The error report messages can then be utilized to allow subscribers to automatically handle failed messages, wherein such corrected messages can be resubmitted to the content-based router.Type: GrantFiled: June 10, 2005Date of Patent: February 3, 2009Assignee: Microsoft CorporationInventors: Arunchallam S. Sivakumar, Kartik Paramasivam, Ruslan Yakushev, Martin T. Wasznicky

Patent number: 7412451Abstract: The invention provides a database schema for representing a workflow process definition (e.g., a schedule). The database schema may also include one or more bindings associated with the schedule, as well as persisted state information and data. The invention further includes a method for storing schedule information in a storage medium, as well as a computer-readable medium having a data structure stored thereon. The storage of schedule-related information provides for ease of version control, and ease of distribution, for example, where several engines point to the same database as a single source of transaction processing or workflow schedule definitions. The definitional database schema may be advantageously employed to reconstruct the schedule definition language solely from information in a database. In addition, the schema may be used for storing instances of running schedules and data associated therewith. This allows ease of schedule state and data monitoring using existing database query tools.Type: GrantFiled: July 26, 2004Date of Patent: August 12, 2008Assignee: Microsoft CorporationInventors: Donald J. McCrady, Amit Mital, A. S. Sivakumar

Patent number: 6996808Abstract: This invention provides a system and method for instrumenting an executable file by replacing an original function in the executable file with a user-supplied function and enabling the user-supplied function to invoke the original function. In particular, the executable file includes an access to the original function. To instrument the executable file, the access to the original function is replaced with an access to the user-supplied function. Access information associated with the original function is retained, which enables the user-supplied function to locate the original function.Type: GrantFiled: February 12, 2000Date of Patent: February 7, 2006Assignee: Microsoft CorporationInventors: Jack Niewiadomski, Lynn Qinlin Tang, A.
