20080199165 | SAFE EYE DETECTION - An eye detection system for safe detection of the eye positions of a subject estimates the distance from the eye detection system to the subject and reduces the power level of at least one primary light source of the eye detection system if the subject is too close to the eye detection system. If the subject is not too close to the eye detection system, the power level of the at least one primary light source of the eye detection system is increased, provided the power level is below a predetermined maximum power level. Primary light from the at least one primary light source reflected from the subject is sensed by an imager to obtain one or more images, from which the eye positions of the subject are estimated. | 08-21-2008 |
20080253614 | METHOD AND APPARATUS FOR DISTRIBUTED ANALYSIS OF IMAGES - A method and apparatus for intelligent distributed analyses of images including capturing the images and analyzing the captured images, where feature information is extracted from the captured images. The extracted feature information is used in determining whether a predefined condition is met, and the extracted feature information is transmitted for further analysis when the predefined condition is met. The extracted feature information is stored and is used to generate statistical information related to the extracted feature information. Further, additional feature information is provided from other databases to implement further analysis including an event detection or recognition. Accordingly, distributed intelligent analyses of images is provided for analyzing captured images to efficiently and effectively implement event detection or recognition. | 10-16-2008 |

If the subject is not too close to the eye detection system, the power level of the at least one primary light source of the eye detection system is increased, provided the power level is below a predetermined maximum power level. Primary light from the at least one primary light source reflected from the subject is sensed by an imager to obtain one or more images, from which the eye positions of the subject are estimated. | 12-11-2008 |
20090078858 | ORIENTATION DETERMINATION UTILIZING A CORDLESS DEVICE - A system for generating orientation information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data are collected using at least one reflector with some orientation-specific characteristic or a reflector integrated into a device that includes some orientation-specific structural feature. Once collected, the two sets of image data are used to generate orientation information related to the reflector. In particular, orientation information related to the reflector is generated by taking the difference between the two sets of image data. | 03-26-2009 |
20100001950 | POSITION DETERMINATION UTILIZING A CORDLESS DEVICE - A system for generating position information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data can be collected in many different ways and may include using a retroreflector as the reflector. The two sets of image data are used to generate position information related to the reflector. In particular, position information related to the reflector is generated by taking the difference between the two set of image data. Because one set of image data includes a stronger indication of the reflector than the other set of image data, the difference between the two sets of image data gives a definitive indication of the reflector's position. | 01-07-2010 |

20090204159 | METHODS AND DEVICES FOR DEFORMITY CORRECTION - An adapter including a coupling portion defining a lumen to receive a pedicle post, an intermediate portion including a first end fixedly attached to a side of the coupling portion and including a second end distal from the coupling portion, and a bolt. A proximal end of the bolt is rotatably coupled to the second end of the intermediate portion and a distal end of the bolt includes a connector. | 08-13-2009 |
20100198270 | Multi-Axial Bone Screw Assembly - A bottom-loading multi-axial bone anchor apparatus is disclosed. The apparatus includes a receiver member, a crown member, a bone anchor and a retaining member. The receiver member defines an upper opening and a lower opening, which may form part of the same opening, a channel, and a groove. The crown member and bone anchor are loaded into the lower opening of the receiver member, and the retaining member fits around the bone anchor and into the groove in the receiver member. The bone anchor is capable of multi-axial positioning with respect to the receiver member. An elongated member is placed in the channel of the receiver member, contacting the crown member, and a compression member is applied via the upper opening. The compression member presses down on the elongated member, which presses down on the crown member and locks the bone anchor between the crown member and the retaining member. | 08-05-2010 |

20130068711 | SURGICAL ASSEMBLY WITH VARIABLE POSITIONING ARM - A surgical assembly includes an actuator. A linking member is connected to and extending from the actuator. The linking member includes a series of at least two interconnected inner links that are relatively movable such that the linking member is disposable between a flexible configuration and a rigid configuration. An arm extends from the actuator and includes a series of relatively moveable outer links that define an axial bore configured for disposal of the linking member. Each outer link defines a first mating surface and a second mating surface disposed in a configuration such that the actuator is engageable to move the linking member from the flexible configuration to the rigid configuration to selectively fix the arm in a selected orientation. Methods of use are disclosed. | 03-21-2013 |
