Abstract: Systems and methods are described, and an example system includes a transport bin configured to carry a baggage item and having spatial reference frame marking detectable by electromagnetic scan and by machine vision. The system includes a robotic arm apparatus at an inspection area, and includes a switched path baggage conveyor that, responsive to electromagnetic scan detection of an object-of-interest (OOI) within the baggage item, conveys the transport bin to the inspection area. The electromagnetic scan generates OOI geometric position information indicating geometric position of the OOI relative to the spatial reference frame marking. The robotic arm apparatus, responsive to receiving the transport bin, uses machine vision to detect orientation of the spatial reference frame marking, then translates OOI geometric position information to local reference frame, for robotic opening of the baggage item, and robotic accessing and contact swab testing on the OOI.

Abstract: A method to analyze video includes obtaining an image series in an Eulerian or Lagrangian frame of reference, selecting one or more specific regions of interest and extracting to remove irrelevant motion and/or noise, decomposing the extracted images into a plurality of frequency bands and extracting a pixel value time series corresponding to the values of a pixel in each spatial frequency band, magnifying the pixel value time series to obtain a magnified pixel value time series, adding the magnified pixel value time series to the pixel value time series to generate a superimposed pixel value time series, and applying a spatial reconstruction to the superimposed pixel value time series to generate an output image series. A system to perform this method is also provided.

Abstract: In one-piece combination, a drive pulley and belt guide for a belt-driven machine. The pulley has a belt-driving section configured for engagement by the belt and a belt-guiding section integral with the belt-driving section. The belt-guiding section has a conically-tapering external surface and an internal surface which is substantially free of reinforcing members and defines a hollow, cup-shaped interior free from structure within the interior.

Abstract: Method for transferring objects in a communications network. A preferred embodiment comprises defining a location of an object to be transferred, providing descriptive information for an invitation, specifying a recipient of the invitation, and issuing the invitation. The invitation can provide a way for a creator of the invitation to provide contextual information, such as object names, instructional and descriptive information related to the object, and so forth, to the recipient to help reduce confusion. Furthermore, the invitation can permit the combination of multiple objects (by the recipient or the creator) to further reduce confusion and the loss of objects. Scheduling can be added to help reduce network resource contention when there are large numbers of objects to be transferred.
