System And Method For Authenticating The Source Of Marked Objects

US Patent:
2004012, Jul 1, 2004
Filed:
Aug 15, 2003
Appl. No.:
10/641967
Inventors:
Frans Coetzee - Princeton NJ, US
Christopher Colfer - London, GB
Andrew Barron - London, GB
Jeffrey Unger - Boston MA, US
John Murphy - Highlands Ranch CO, US
Gary Lerner - Lexington MA, US
Assignee:
GenuOne, Inc - Boston MA
International Classification:
G06K009/00
US Classification:
382/112000, 283/072000
Abstract:
An authentication system and method for identifying the source of a marking formed from marking media is disclosed. A registration system preferably tags batches of marking media with taggant material and, for each batch, stores physical property information representing one or more physical properties of that batch. A source assignment system receives source identification information for each of a plurality of sources, stores the source identification information in a database and, for each source, links the source identification information with at least one batch. A source identification system comprises at least one instrument operable to provide physical property information for the media in a marking. The identification system also includes an analysis system operable to compare the physical property information for the media in the marking with the physical property information associated with batches, and to then determine whether there one or more matches of physical property information exist.

Wind Driven Power Generator

US Patent:
4012163, Mar 15, 1977
Filed:
Sep 8, 1975
Appl. No.:
5/611090
Inventors:
Franklin W. Baumgartner - Denver CO
John Michael Murphy - Littleton CO
International Classification:
F03D 706
US Classification:
415 2
Abstract:
A turbine type power generator includes a rotor having a vertical shaft to drive a load which may be an electric generator or mechanical gear train or other device for using or transmitting power. Generally vertically extending blades are secured at their ends to the rotor shaft and are set at an angle to the relative wind to be driven thereby. The rotor is surrounded by wind controlling shield means through which the air flow passes to contact the blades in the proper direction for causing rotation. The free flow air inlet area is substantially less than the maximum projected area of the shield means normal to the relative wind so that the total wind trapped must flow through a reduced area with a consequent increase in velocity to impart more energy to the rotor blades. One form of shield means is a structure of the same general shape as the rotor surrounding the rotor on all sides and having vertically extending passages spaced around its perimeter to lead the air flow to the blades. Another form of shield means is an elongate, horizontally extending tube with the rotor mounted therein at an intermediate position.
