Publication number: 20230245183Abstract: A system may generate buyback guarantee options for a particular vehicle, each option based on a user satisfying respective predetermined condition(s). The system may receive a user selection at a future date claiming one of the guarantee options. The system may determine whether the user satisfied the applicable predetermined condition(s), and whether the buyback guarantee price is greater than the current selling price of the vehicle. Responsive to such determinations, the system may provide the user with payment option(s) for receiving the difference between the buyback guarantee price and the vehicle current selling price.Type: ApplicationFiled: January 31, 2022Publication date: August 3, 2023Inventors: Vijay Viswanathan, Gunjan Patel, Jason-Vi Tuan Dang

Patent number: 8298666Abstract: An electroluminescent (EL) phosphor is described wherein each individual phosphor particle is encapsulated in an inorganic coating, preferably aluminum oxyhydroxide. The encapsulated phosphor shows an extreme insensitivity to atmospheric moisture and suffers only minor loss of initial brightness in lamps. The method of applying the coating is a hybrid process, which involves EL phosphor particles first being coated with a thin inorganic film using an atomic layer deposition (ALD) method in a fluidized bed wherein the precursors are introduced sequentially in repeated cycles, subsequently followed by an additional coating layer applied by a chemical vapor deposition (CVD) method in which the precursors are introduced simultaneously.Type: GrantFiled: January 12, 2007Date of Patent: October 30, 2012Assignee: Global Tungsten & Powders Corp.Inventors: Chen-Wen Fan, Tuan A. Dang, Joan M. Coveleskie, Frank A. Schwab, Dale E. Benjamin, David C. Sheppeck

Patent number: 7246272Abstract: A plurality of data packets encoded according to a first protocol are received which encapsulate data encoded according to a second protocol. A first source address is extracted from the packets according to the first protocol, it is determined whether or not the first source address is a substantial duplicate of a known assigned address. If it is a duplicate, a second source address is extracted from the encapsulated data according to the second protocol, and the first source address and said second source address are provided in an enhanced error log so that a system administrator may correct the duplicate assigned address. Enhanced embodiments of the invention included analysis of data encapsulated by a third, fourth and subsequent protocols, and automatic determination of each protocol encoding format.Type: GrantFiled: January 16, 2004Date of Patent: July 17, 2007Assignee: International Business Machines CorporationInventors: Rafael Graniello Cabezas, Anh Tuan Dang, Binh Hua, Jason Eric Moore, Elizabeth Silvia

Publication number: 20040199828Abstract: A method and apparatus for tracing troubleshooting events for aiding technical assistance personnel are provided. With the method and apparatus, a user initiates a technical assistance tracing mechanism on his/her client device. The technical assistance tracing mechanism includes event listeners that are registered with the operating system of the client device. These event listeners are notified when, for example, an input device event occurs, when a graphical user interface event occurs, and the like. These events are recorded by the technical assistance tracing mechanism of the present invention as a log of events. This log of events may then be provided to a computing device which is being used by the technical assistance specialist for use in diagnosing and curing the problems encountered by the user. An automated tool may be provided for analyzing the event log and/or emulating an operating system environment so that the event log may be replayed in a graphical manner.Type: ApplicationFiled: April 1, 2003Publication date: October 7, 2004Applicant: International Business Machines CorporationInventors: Rafael Graniello Cabezas, Anh Tuan Dang, Jason Eric Moore, Elizabeth Silvia
