Abstract: An apparatus comprises a first detector mounted on a sliding bar and an electromagnetic source including a collimator to generate an exposure window. The apparatus comprises a control system configured to slide linearly the first detector along the sliding bar and synchronously move the collimator to direct the exposure window to the first detector. The movements of the exposure window are registered to movements of the first detector.

Abstract: A portable device receives an encrypted message from an electronic health record database server including a request to perform a biometric authentication to approve a transaction. The device prompts a user to speak a pass phrase. The device creates a set of variables including the pass phrase and at least one more variable characterizing the spoken voice. The authentication module transmits an encrypted message to the health record database server including a session identification information and the set of variables. In response, the device receives an encrypted message from the health record database server determining whether the biometric authentication is successful and the transaction is approved, wherein determination is made by the health record database server and is based on verifying the session identification information, the pass phrase, and the user identity.

Abstract: A system for registration of images includes a processor for receiving a temporal sequence of frames from multiple cameras viewing a region of interest. The temporal sequence of frames obtained by one camera is precisely timed to the temporal sequence of frames obtained by the other cameras. The processor modifies the temporal sequence of frames into a hierarchical sequence of frames. The hierarchical sequence of frames includes at least first and second levels. The processor registers frames belonging in the first level separately from frames belonging in the second level. The first level includes frames having a first amount of pixel overlap between one frame and another frame, and the second level includes frames having a second amount of pixel overlap between one frame and another frame. The first amount of pixel overlap is greater than the second amount of pixel overlap.

Abstract: For dental and facial imaging, a source of x-rays (14) or other penetrating radiation and a detector (20) are mounted opposite one another on a rotatable gantry (28), so that the head of the patient can be positioned between the source (14) and the detector (20), with the axis of rotation (36) of the gantry passing through the patient's head. The detector or the source are mounted so they can translate and/or pivot horizontally or vertically. The gantry is angulated so that the source or the detector may not be at the same height relative to the patient's head. The gantry can telescope, moving the source and the detector closer together or further apart. The collimator changes dynamically with the motion of the gantry and/or the source and detector to scan a smaller portion of the scan field.

Abstract: Systems and methods for detecting objects and weather in space are disclosed. A system for detecting an object in space and space weather includes at least one spacecraft, at least one radiation source, at least one detector, and a controller. The at least one radiation source and the at least one detector are coupled to the at least one spacecraft. The at least one radiation source is configured to transmit a signal. The at least one detector is configured to detect the signal. The signal may be reflected from an object in space. The controller is coupled to the spacecraft and is in communication with the plurality of detectors. The controller is programmed to calculate either a relative position of the object based or a plasma parameter in a region traversed by the signal based on the detected signal.

Abstract: An apparatus for generating a panoramic image of part of a target, the apparatus including a source of penetrating radiation and a detector aligned with the source of penetrating radiation. The detector and source of penetrating radiation are rotate-able together with respect to the target. The detector has an array of radiation sensors arranged in rows and columns and is configured to output contents of each radiation sensor in the array of radiation sensors. The apparatus also includes a computer connected to the detector and configured to generate a panoramic image by combining data from sensors in the same row in different columns in different readout intervals, corresponding to different positions of the detector as it rotates with respect to the target. The combined outputs are selected to represent rays of radiation passing through a point on a defined curve.

Abstract: A collaborative knowledge management system (CKMS) includes application interfaces collecting data objects from and providing data objects to respective application programs including, for example, word processing, spreadsheet, graphics, e-mail, general ledger, ERP and other programs and utilities. The data objects are associated with respective relationships identifying other data objects, applications and users (whereby users include, but are not limited to people, machines and software). A set of rules defines how the data objects are to react to various systems states and actions of the objects of the relationships. Objects may be stored in a common format, or lingua franca, so that diverse applications and users may form, share and interrelate knowledge provided by the data objects and collaborate in the creation of new data objects and define new relationships.
