International Classification:

G06F 12/14

US Classification:

713190, 713194

Abstract:

Systems and methods are disclosed for protecting a computer program from unauthorized analysis and modification. Obfuscation transformations can be applied to the computer program's local structure, control graph, and/or data structure to render the program more difficult to understand and/or modify. Tamper-resistance mechanisms can be incorporated into the computer program to detect attempts to tamper with the program's operation. Once an attempt to tamper with the computer program is detected, the computer program reports it to an external agent, ceases normal operation, and/or reverses any modifications made by the attempted tampering. The computer program can also be watermarked to facilitate identification of its owner. The obfuscation, tamper-resistance, and watermarking transformations can be applied to the computer program's source code, object code, or executable image.

US Classification:

562553, 562531

Abstract:

The present invention provides a method for the synthesis of β-amino acids. The method also provides methods yielding α-substituted β-amino aldehydes and β-substituted γ-amino alcohols. The present method according to this invention allows for increased yield and easier purification using minimal chromatography or crystallization. The methods described herein are based on an aldehyde aminomethylation which involves a Mannich reaction between an aldehyde and a formaldehyde-derived N,O-acetal (iminium precursor) and a catalyst, such as, for example, L-proline or a pyrrolidine. The invention allows for large scale, commercial preparation of β-amino acids.

Filed:

Apr 9, 2002

Appl. No.:

10/118310

Inventors:

William Horne - Marietta GA, US
Dale Humphries - Suwanee GA, US

International Classification:

G06F017/60

US Classification:

705/032000

Abstract:

A system and method for time and attendance record keeping includes receiving identifying information from an employee at a point-of-sale terminal; recording clock in data for the employee; recording clock out data for the employee; using the clock in data and the clock out data to produce a time record for the employee; and transmitting the time record to a host system via a communication network. The host system is accessible by a manager via the Internet or other similar platform so that the manager can print report and other manipulate the time and attendance records remotely through a personal computer or other Web enabled portable device. Moreover, the manager can access the time and attendance records at the POS device.

12/348832

Inventors:

Robert S. Schreiber - Palo Alto CA, US
William G. Horne - Lawrenceville NJ, US

Assignee:

HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P. - Houston TX

International Classification:

H04L 9/32

US Classification:

726 1

Abstract:

A method includes selecting a first biclique role in a plurality of roles and finding all roles in the plurality that have a set of vertices of a second type that is a subset of a set of vertices of the second type in the first role; removing each of the subsets from the set of vertices of the second type corresponding to the first role; and reassigning the vertices of the first type to the roles such that original associations between the vertices of the first type and the vertices of the second type are maintained.
