A generally cylindrical (e.g., faceted cylindrical) columnar locator permits easy application of reflective tape. Other examples discusses a unitary fiducial marker with multiple divots and a swiveling and/or tilted fiducial marker divot, each of which allows manipulation of a positioning wand into a remote camera's field of view. Another example includes at least one reflector that can be aimed. A further example discusses an imagable fiducial marker carrier that is attachable to a single location on a patient's skull to reduce trauma. A keying arrangement fixedly defines the orientation of the carrier, allowing detachment and reattachment in the same orientation. | 08-26-2010 |

20130214898 | SYSTEM AND METHOD FOR SECURE ENTRY USING DOOR TOKENS - Secure door entry without a traditional card reader is made possible by tagging the door with an unpowered, unique token which can be read by a user's personal mobile electronic device. The user's device transmits both door and user identification to a remote server, where the decision is made whether to open the door. If so, the server sends an open door signal using the IP suite of protocols to an electronic bridge, which in turn passes the signal on to a door strike, opening the door. Another signal may be sent to an annunciator. Single-use digital tokens may also be used to open the doors. The permissions relating to doors or other physical assets may also be used to grant access to logical assets. | 08-22-2013 |

In other cases, the scanning of a token may cause a remote server to perform an action that depends on the user being in proximity to the token. | 08-22-2013 |
20140070002 | SYSTEM AND METHOD FOR PRINTER OPERATION BASED ON USER PROXIMITY - Secure, shared operation of a group printer is made possible by tagging a printer with an unpowered, unique, identifying token which can be read by a user's personal mobile electronic device. The user's device transmits both printer and user identification to a remote server or computer, from which a command to start the printer is issued. Commands may be sent using the IP suite of protocols. The system may also support single-use digital tokens to allow users external to the group to print on an occasional basis. | 03-13-2014 |

20150310040 | GROUPING AND RANKING IMAGES BASED ON FACIAL RECOGNITION DATA - Technologies for grouping images, and ranking the images and the groupings, based on entities shown in the images. Images may be grouped based on faces shown in the images. Different images with faces that indicate the same entity (e.g., Adam) may be automatically grouped together. Different images with faces that indicate the same multiple entities (e.g., the people in my family) may also be automatically grouped together. Such automatic grouping may be based on facial recognition technologies. Further, images and groups of images may be automatically ranked based on the faces shown and entities represented. Such rankings may also be influenced by adjacent data that indicates family and friends and the like, and that can be used to identify such entities in the images. | 10-29-2015 |
20150310261 | CREATION OF REPRESENTATIVE CONTENT BASED ON FACIAL ANALYSIS - Technologies for analyzing various features detected in a face detected in an image. Such features may include at least the eyes, eyebrows, node, and mouth of a face. Such analyzing may include scoring aspects of these features. Such scores may be weighted. The analysis may be used to determine expressions and/or poses of the face, as well as indicate if the face is smiling, frowning, or neutral. An overall quality score for the face may also be determined and provided based on the aforementioned analysis as well as whether or not the face is near an edge of the image or cut-off in the image. Finally, a face signature may be determined that uniquely identifies the face, at least within the scope of the analyzed features. Such face signatures may be used to detect a similar face in other images. | 10-29-2015 |
20150317510 | RATING PHOTOS FOR TASKS BASED ON CONTENT AND ADJACENT SIGNALS - Technologies for selecting a representative subset of images from a set of images, the selecting based at least in part on rating the images in the set based on task, Image, and/or adjacent information. An Indication of the task may be embodied in a query provided by a user. The task may indicate the user's intended use of the subset of images. The set of images may be grouped into one or more clusters that are based on technical attributes of the images in the set, and/or technical attributes indicated by the task. Adjacent information may be obtained from sources that are generally unrelated or indirectly related to the images in the set. Technical attributes such as face quality, face frequency, and relationship are based on facial recognition functionality that detects faces and their features in an image, and that calculates information such as a face signature that, across the images in the set, uniquely identifies an entity that the face represents, and that determines facial expressions such as smiling, sad, and neutral. | 11-05-2015 |
