Patent number: 11696837Abstract: An intervertebral spacer implant (80) is provided with a retention mechanism (86) to help alleviate expulsion and movement of the implant when placed in the spine while providing an implant that is easier to insert in the spine. In one embodiment the retention mechanism comprises a keel on at least one of the inferior or superior faces of the spacer implant preferably extending in an anterior-posterior direction. In another embodiment the implant comprises a spacer (84) and a plate (82), the plate comprising a supplemental or alternative retention mechanism. In one embodiment the retention mechanism comprises one or more holes (88) in the anterior end of the plate. In yet another embodiment, the retention mechanism comprises one or more blades that are in a first position when inserted and are preferably rotated to a second position that engages the superior and inferior vertebrae.Type: GrantFiled: December 18, 2019Date of Patent: July 11, 2023Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Dominique Messerli, Ryan T.

Patent number: 9135948Abstract: Functionality is described for reducing the unauthorized reproduction of optical media, such as optical discs of various types. The functionality operates by adding a physical descriptor to an optical medium, forming reference descriptor information based on the descriptor, signing the reference descriptor information to produce authenticity information, and adding the authenticity information to the optical medium. At a point of consumption, the functionality operates by reading the authenticity information and reading the descriptor. Based on the information that is read, the functionality performs cryptographic analysis and descriptor-based analysis to validate the optical medium. The functionality includes various provisions to reduce the impact of wear and tear on the above-summarized analysis. The functionality can be applied to stamped or recordable optical media.Type: GrantFiled: July 3, 2009Date of Patent: September 15, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Darko Kirovski, David E.
