US Patent:

7996881, Aug 9, 2011
Filed:

Nov 9, 2005
Appl. No.:

11/269887
Inventors:

Philip W. Flack - Leesburg VA, US
Yan Cheng - Great Falls VA, US
Zhihong Zhang - Great Falls VA, US
Matthew Nguyen - Fairfax Station VA, US
Assignee:

AOL Inc. - Dulles VA
International Classification:

G06F 7/04
G06F 15/16
G06F 17/30
H04L 29/06
US Classification:

726 3, 726 2, 726 4, 726 5, 726 6, 726 8
Abstract:

Techniques are described for repairing some types of user account problems that interfere with granting a user access to a computer system and doing so during a process to authenticate the user in a way that does not require the user to re-enter authentication information or require the user to restart a communication session with the computer system. In response to a determination that a user's account has a problem during an authentication process, techniques are provided to enable a user to execute an appropriate process or processes to fix the user account, after which the authentication process continues. In this way, the correction to the user account may appear to be seamless to the user.

Method For Translation Of Assembler Computer Language To Validated Object-Oriented Programming Language
view source
US Patent:

20180253287, Sep 6, 2018
Filed:

Apr 28, 2017
Appl. No.:

15/582563
Inventors:

Jian Wang - Sterling VA, US
Zhenqiang Yu - Rockville MD, US
Yan Cheng - Great Falls VA, US
International Classification:

G06F 9/45
G06F 9/44
Abstract:

The method for translation of assembler computer language to validated object-oriented programming language converts Assembler Language Code (ALC) logical processes to equivalent object-oriented processes. The method uses various iteratively updated rules sets and graphical analysis tools to automate the translation process. The method further uses a Technical Rule Language (TRL) as an intermediate scripting language to map ALC sequential instruction sets to simplified Java constructs, which are verified and then translated to Java executable code.
