Title: Deposited thin films and their use in separation and sarcrificial layer applications
Inventor: LEE YOUNGCHUL
IPC: C23C16/24
Filed: 2001-04-17
Abstract: This invention uses large surface to volume ratio materials for separation, release layer, and sacrificial material applications. The invention outlines  the material concept, application designs, and fabrication methodologies. Th e invention is demonstrated using deposited column/void network materials as examples of large surface to volume ratio materials. In a number of the specific applications discussed, it is shown that it is advantageous to crea te structures on a laminate on a mother substrate and then, using the separatio n layer material approach, to separate this laminate from the mother substrate  using the present separation scheme. It is also shown that the present materials have excellent release layer utility. In a number of applications it is also shown how the approach can be used to uniquely form cavities, channels, air-gaps, and related structures in or on various substrates. Further, it is demonstrated that it also can be possible and advantageous to  combine the schemes for cavity formation with the scheme for laminate separation.

Abstract: Canine monocytic ehrlichiosis, caused by Ehrlichia canis is a potentially fatal disease of dogs that requires rapid and accurate diagnosis in order to  initiate appropriate therapy leading to a favorable prognosis. In the invention described herein, a new immunoreactive E. canis surface protein ge ne of 1170-bp was cloned, which encodes a protein with a predicted molecular ma ss of 42.6 kilodaltons (P43). The P43 gene was not found in E. chaffeensis DNA by Southern blot, and antisera against recombinant P43 (rP43) did not react wit h E. chaffeensis by IFA. The P43 was located on the surface of E. canis by immunoelectron microscopy. Forty-two dogs exhibiting signs and/or hematologi c abnormalities associated with canine ehrlichiosis were tested by IFA and by Western immunoblot. Among the 22 samples that were IFA positive for E. canis , 100 % reacted with the rP43, 96 % with the rP28, and 96 % with the rP140. Th e specificity of the recombinant proteins compared to IFA was 96 % for rp28, 8 8 % for P43 and 63 % for P140. Results of this study demonstrate that the rP43  and rP28 are sensitive and reliable serodiagnostic antigens for the diagnosi s of Ehrlichia canis infections.

Abstract: In a method for manufacturing instant lottery tickets where book numbers and ticket numbers are printed on the tickets utilizing a dual security process such that the book numbers are shuffled in each pool before the tickets are printed to break the link between the book numbers the ticket numbers or validation numbers, a reversing process can be used under certain predefined conditions to relate the original book numbers to the ticket numbers or validation numbers. In one example, where a shuffling algorithm utilizing seeds is used to shuffle the book numbers, the seeds used in the algorithm are maintained in an encrypted file. A decryption key for the encrypted seed file can be used by a lottery administration or trusted third party to reconstruct game play indicia for game adjustment purposes and manufacturing adjustments. To enhance security, the independent third party can also be used to administer the encryption and decryption keys during the ticket manufacturing process and during life of the instant ticket game.
