  • Patent number: 11968199
    Abstract: Systems and methods are provided for authenticating image files when network connections should not or cannot be used to transfer image files. A user device application may capture an image at a user device, generate an image file, and generate a hash file based on the image file. Instead of sending the image file to an authentication server for authentication, the application may send the hash file. If desired, the application may transfer the image file when a desirable network connection is available. Any alteration to the image file in the meantime will result in a different hash file for the altered image file, thus allowing detection of altered image files. This approach offers decreases the amount of data that is required to be transmitted in low or undesirable signal conditions, while maintaining an ability to detect alterations to image files that may have been made in the meantime.

  • Publication number: 20110191873
    Abstract: This invention is directed towards methods of destabilizing proteins in living cells, and their use for the development of novel assays. In one embodiment, the invention comprises the use of non-cleavable multimerized ubiquitin fusion proteins to destabilize a target protein, such as a reporter moiety. In one aspect of this method the constructs also comprises a linker that operatively couples the reporter moiety to the multimerized ubiquitin fusion protein. In this embodiment, enzymatic modification of the linker results in a modulation of the coupling of the reporter protein to the multimerized ubiquitin domains resulting in a change in the stability of the reporter moiety. The level of the reporter moiety in the cell can then be used as a measure of the enzymatic activity in the cell. In another embodiment the invention provides for a generalized way of coordinately regulating the cellular concentration of a plurality of target proteins.

  • Publication number: 20070034614
    Abstract: The present invention provides a method of forming a polishing pad for chemical mechanical planarization utilizing laser ablation. In particular, the method includes providing a laser to cut a groove into the polishing pad and providing a beam splitter to split a laser beam from the laser. Further, the method provides splitting the beam from the laser to provide multiple laser beams onto the polishing pad and wherein the multiple laser beams have effective cutting areas that at least overlap each other.
