Filed:

Oct 28, 2005

Appl. No.:

11/260906

Inventors:

International Classification:

G06K 9/00
H04N 7/167

US Classification:

382100, 380200

Abstract:

A correlation-based system for watermarking continuous digital media at the system application level. It is a post-compression process for watermarking where no a priori knowledge of the underlying compression algorithm is required. Per each compressed media frame, a current unique digital signature is generated based on the data from the current compressed frame plus the digital signature that has been previously generated. The signature thus generated is then used in conjunction with the next compressed frame to generate the next unique digital signature. All digital signatures are correlated according to the above process until a “reset” signal is issued. A new chain of correlated digital signatures is produced by the system with a pre-determined initial signature.

US Classification:

382100, 382278, 380200

Abstract:

A two level cross-correlation based system for watermarking continuous digital media at the system application level. It is a post-compression process for watermarking where no a priori knowledge of the underlying compression algorithm is required. Per each compressed media frame, a current unique digital signature is generated based on the data from the current compressed frame plus the digital signature that has been previously generated. The signature thus generated is then used in conjunction with the next compressed frame to generate the next unique digital signature. All digital signatures are correlated according to the above process until a “reset” signal is issued. A new chain of correlated digital signatures is produced by the system with a pre-determined initial signature.

International Classification:

A61F 9/008

Abstract:

A system and method for performing ophthalmic surgery using an ultra-short pulsed laser is provided. The system includes a laser engine configured to provide an ultra-short pulsed laser beam, optics configured to direct the laser beam to an undocked eye of a patient, an eye tracker configured to measure five degrees of freedom of movement of the undocked eye, an optical coherence tomography module configured to measure depth of the undocked eye, and a controller configured to control laser beam position on the undocked eye toward a desired laser pattern based on depth and the five degrees of freedom of movement of the undocked eye. Adaptive optics are also provided. Also disclosed are a scleral ring including fiducial markings and a compliant contact lens and fluid tillable contact lens configured to facilitate ultra-short pulsed laser surgery while reducing or eliminating eye docking requirements.
