Patent CA-2538164-A1 (CA)
Inventor: HUGHES JAMES J
IPC: C23F1/00
Filed: 2004-09-17
Abstract: Ophthalmic surgical blades (734) are manufactured from either a crystalline or polycrystalline material, preferably in the form of a wafer. The method comprises preparing the crystalline or polycrystalline wafers by mounting them and machining trenches into the wafers. Methods for machining the trenches, which form the bevel blade surfaces (752), include a diamond blade saw, laser system, ultrasonic machine, a hot forge press and a router. The wafers are then placed in an etchant solution which isotropically etches the wafers in a uniform manner, such that layers of crystalline or polycrystalline material are removed uniformly, producing single, double or multiple bevel blades (734). Nearly any bevel angle can be machined into the wafer which remains after etching. The resulting radii of the blade edges is 5-500 nm, which is the same caliber as a diamond edged blade, but manufactured at a fraction of the cost. The ophthalmic surgical blades can be used for cataract and refractive surgical procedures, as well as microsurgical, biological and non-medical, non-biological purposes.

Title: Electronic transaction verification system
Inventor: MCNEAL JOAN TIBOR
IPC: G06F21/34
Filed: 2005-04-01
Abstract: An electronic transaction verification system for use with transaction tokens such as checks, credit cards, debit cards, and smart cards, that gathers and transmits information about the transaction token and biometric data. The system preferably has the ability to read or scan transaction and account information printed or encoded on the transaction token, digitally encode biometric data, scan drivers' licenses or other identification cards, and take a signature of a customer, all at a transaction location for purposes of account verification. The electronic transaction verification system preferably digitizes various indicis of the token, such as the magnetic ink (MICR) line on a presented check or the magnetic strip on a credit card or debit card, and transmits the transaction information data to a central system, at which the central system compares the inputted data with an existing database of information to determine if the customer at the point of the transaction is in fact authorized to use the account, and if the account is in satisfactory condition for approval of the transaction. The electronic verification system includes a biometric data device for recording and/or transmitting biometric data taken at the point of the transaction. The device alternatively prints the biometric data on, or in conjunction with, the token, either in actual or digitally encoded form, such that the biometric data can be checked subsequently against a database at the time the token is processed at a financial institution. The system alternatively includes a device for scanning an information card which contains biometric data such as a proper fingerprint and/or a signature, and the remotely gathered data can be compared to the recorded data on the card, in addition to or instead of, transmission of the gathered data to the electronic, biometric and signature databases.
