Abstract: Disclosed is a method for controlling access for at least one tracked object, including: acquiring or receiving a series of two-dimensional images assumed to be taken of the at least one tracked object, and also position data in respect of the at least one tracked object; assigning a unique tracking identifier to the at least one tracked object; determining a trajectory of the at least one tracked object from the position data; determining if there is a discontinuity in the trajectory or data computed from the trajectory, and if a discontinuity is detected, acquiring or receiving one or more new images of the at least tracked object, and assigning a new unique tracking identifier to said at least one tracked object; and determining whether access should be allowed, on the basis of at least one of the one or more new images if discontinuity is detected, or on the basis of the at least one image from the series of two-dimensional images if discontinuity is not detected.

Abstract: Systems, apparatuses, and methods are described for determining the location of a worker in a plant, such as a petrochemical manufacturing or refining facility in order to render an augmented view of at least one asset in the vicinity of a fiducial marker. A field worker mobile device may scan the fiducial marker and render operating values for a measurable element of the assets in the field of view of the mobile device. Location of the mobile device with respect to the assets in the vicinity of the fiducial marker may be determined based upon the known location and orientation of the fiducial marker and/or the known location and orientations of the assets relative to the fiducial marker.

Abstract: A method includes identifying one or more first devices contained in at least one image captured by a mobile device. The method also includes obtaining data associated with at least one of: the one or more first devices and one or more second devices connected to or interacting with the one or more first devices. The method further includes presenting information overlaid over the at least one image by the mobile device to a user, where the presented information includes the data or information based on the data. The presented information varies based on perceived distance or proximity of the mobile device to the one or more first devices.

Abstract: A method of real-time markerless measurement and calibration of a patient positioning system includes computing a three dimensional point cloud representation of a patient by using a camera to obtain depth points of the patient, where the z-direction corresponds to a direction along the focal length of the camera, demanding a z-limit that corresponds to a lower (z-min) and an upper (z-max) specification, computing a point cloud covariance and a point cloud mean for an optimized principle components analysis to compute a torso topography of the patient, determining a center point of the point cloud as an anchor measurement region and using the camera to determine a distance to the patient to establish an angle between a patient torso and a vector that is perpendicular to the camera, averaging the depth measurements in reference regions and compensating for parallax error in real-time during a calibration measurement or radiotherapy treatment plan.

Abstract: An adjustable chromatic harmonica incorporating an adjustable mouthpiece where, for each mouth-hole, the player's breath may be selectively connected to one or more available reed cells. This is by means of a rotatable cup-shaped valve, with an opening or port in its side, being mounted in each mouth-hole such that the port can be registered by rotation with one of a group of surrounding air ducts, each of which is connected to one or more reed cells in the body of the harmonica. In some embodiments an apertured slide is interposed between the mouthpiece and the body. In some embodiments devices are provided for rotating the valves in independent groups while the harmonica is being played. In embodiments where each group of mouth-holes can be independently adjusted, a large number of physical states is possible. Consequently, some embodiments have the capability of playing chromatic melodies and several common chord types in all twelve musical keys.
