20140075513 | DEVICE TOKEN PROTOCOL FOR AUTHORIZATION AND PERSISTENT AUTHENTICATION SHARED ACROSS APPLICATIONS - Various techniques for providing a device token protocol for authorization and persistent authentication shared across applications are disclosed. In some embodiments, a device token protocol for authorization and persistent authentication shared across applications includes sending user credentials to a remote server to authenticate a user on a device for a plurality of applications; and receiving a device token from the remote server for the user to authenticate the user for the plurality of applications on the device, in which the device token facilitates authentication and authorization. | 03-13-2014 |
20140289340 | Invitations for Establishing Relationships - Techniques for invitations for establishing relationships are described. In at least some embodiments, an architecture is implemented which provides simple and integrated ways for establishing relationships between various entities. The architecture includes invitations that can be used to invite users to establish relationships with entities. A user that receives an invitation can interact with the invitation, such as to accept or decline an invitation to establish a relationship with an entity. If a user accepts an invitation, a relationship can be established between the user and an inviting entity. In at least some embodiments, the relationship can enable the user to perform various actions and/or access resources associated with the entity. | 09-25-2014 |

20100281025 | METHOD AND SYSTEM FOR RECOMMENDATION OF CONTENT ITEMS - A method of generating recommendations for content items comprises providing a domain ontology where concepts are characterized by a term vector with terms and associated weights. Associated term sets, each of which comprises a set of terms that characterize a content item, are further provided. A concept set is generated for each associated term set by determining the concepts of the domain ontology that match the terms of the associated term set. In addition, a user profile for a user is provided where the user profile comprises at least some of the concepts of the ontology coupled with preference weights. Recommendations for content items are generated based on the plurality of associated concept sets and the user profile. The invention may allow improved and/or facilitated generation of recommendations from text based characterizing data. | 11-04-2010 |

20100010541 | SPINAL FIXATION PLATES AND PLATE EXTENSIONS - A spinal fixation plate that is adapted to be implanted in a variety of positions in the occiput is provided. In general, the plate has a substantially planar configuration and it includes a mid-line or central portion having several thru-bores formed therein, and first and second opposed branch portions that extend from the central portion and that also include at least one thru-bore formed therein. The configuration of the branch portions relative to the central portion, as well as the position of the mid-line thru-bores formed in the central portion in relation to the thru-bore(s) formed in each branch portion, allow the spinal fixation plate to be implanted in a variety of positions in the occiput, thus allowing the optimal implant site to be selected. | 01-14-2010 |
20100222780 | METHOD AND APPARATUS FOR RETAINING SCREW IN A PLATE - A retention system for maintaining a screw to a vertebral plate is described herein. One or more screws extend through apertures within the vertebral plate. A cavity is positioned adjacent to and overlaps into the aperture. A ring is positioned within the cavity and held in position by a cap. The cap attaches to the plate to prevent removal of the ring. The ring is deflectable between a first shape to allow the screw to be inserted and removed from the aperture, and a second shape to prevent screw back-out from the aperture. | 09-02-2010 |
20130006305 | SPINAL ROD CONNECTOR - A rod connector for joining a first rod and a second rod includes bore holes that are offset and/or non-parallel to each other. The rod connector provides an offset or non-parallel connection between the rods that allows for the rods to match the contour of a patient's body without requiring bending of the rods. The rod connector may include a first bore hole for receiving the first spinal rod and a second bore hole for receiving the second spinal rod that is adjustable relative to the first bore hole to adjust the position and/or orientation of the second spinal rod relative to the first spinal rod. The rod connector may comprise a first housing component defining the first bore hole and a second housing component that is movable relative to the first housing component and defining the second bore hole. | 01-03-2013 |
20140330316 | SPINAL ROD CONNECTOR - A rod connector for joining a first rod and a second rod includes bore holes that are offset and/or non-parallel to each other. The rod connector provides an offset or non-parallel connection between the rods that allows for the rods to match the contour of a patient's body without requiring bending of the rods. The rod connector may include a first bore hole for receiving the first spinal rod and a second bore hole for receiving the second spinal rod that is adjustable relative to the first bore hole to adjust the position and/or orientation of the second spinal rod relative to the first spinal rod. The rod connector may comprise a first housing component defining the first bore hole and a second housing component that is movable relative to the first housing component and defining the second bore hole. | 11-06-2014 |

20100036420 | HEAD-TO-HEAD CONNECTOR SPINAL FIXATION SYSTEM - A spinal fixation system comprising at least two bone anchors, a rod connecting the bone anchors and a connecting plate extending from a proximal surface of at least one of the bone anchors. A method of fixing vertebrae relative to each other comprising the steps of: implanting bone anchors in two adjacent vertebrae, each bone anchor having a rod receiving portion; placing a rod in the rod receiving portions, thereby connecting the bone anchors; threadably engaging set screws in the rod receiving portions of at least a portion of the bone anchors, thereby fixing the rod to the bone anchors; mating one end of a connecting plate to a proximal bearing surface of at least a portion of the bone anchors; and engaging a cap with at least a portion of the set screws, thereby fixing the connecting plate to the bone anchors. | 02-11-2010 |

20130188036 | CAMERA SYSTEM FOR HAZARDOUS ENVIRONMENTS - A camera system is provided for use in a high-radiation environment includes a camera assembly with a housing enclosing an image sensor for generating a digital signal of a detected image and a first serializer/deserializer (SERDES) for converting the digital signal from the image sensor into a serial bit stream. A transmission medium transmits the serial bit stream to an image processing module located outside of the high-radiation environment where a second SERDES deserializes the serial bit stream to generate a decoded image signal which is processed by an image processor to generate an output at a display device corresponding to the detected image. | 07-25-2013 |
