Abstract: A system includes computer-readable media having memory, one or more processors, and instructions in the memory that, when executed by the one or more processors, cause the processor(s) to: generate an archive container, a cooked container, an ingest container, and an index container; receive, in the ingest container, a plurality of time series data elements; identify a data format for each of the time series data elements; divide the plurality of time series data elements into a plurality of data sub-elements based on a corresponding append binary large objects (blobs) contained in the cooked container; generate, statistical data for the plurality of time series data elements for each of one or more index blobs contained in the index container; and output: the statistical data to the index container; the plurality of data sub-elements to the cooked container, and the plurality of time series data elements to the archive container.

Abstract: A remote methane detector is described herein. The remote methane detector includes an external shell defining an interior cavity. The remote methane detector also includes an airflow aperture. The remote methane detector also includes a methane sensor disposed within the interior cavity, wherein the methane sensor is adapted and configured to receive airflow from the airflow aperture and to detect methane within the airflow. The remote methane detector also includes a rechargeable power source. The remote methane detector also includes a low-energy telecommunications transceiver chain. The remote methane detector also includes an energy collector adapted and configured to collect renewable energy and to power at least the methane sensor and the low-energy telecommunications transceiver chain.

Abstract: An oscillatory PEP therapy device (100) has valve (10) mounted at the end of a rocker arm (12) such that the valve is opened and closed during expiration through the device, thereby causing displacement of the rocker arm up and down. The housing (2) of the device (100) is transparent so that the camera (20) on a mobile phone (200) can be positioned to view displacement of the rocker arm (12) during use. The phone (200) is programmed to extract a signal indicative of the frequency of oscillation of the rocker arm (12) and this is displayed on the screen of the phone to provide feedback to the user.

Abstract: A method and system for reconstructing and segmenting an image of the contents of a container. The method includes receiving actual scan data from a scan of the container, reconstructing the actual scan data to obtain a reconstructed image, and segmenting the reconstructed image to obtain a segmented image. The method also includes deriving simulated scan data corresponding to the segmented image, calculating an error term based on a difference between the simulated scan data and the actual scan data, and determining whether a criterion is satisfied. The method further includes using the error term to produce a modified reconstructed image and repeating the preceding steps with the modified reconstructed image substituted for the reconstructed image if the criterion is not satisfied, and outputting information from the segmented image if the criterion is satisfied.

Abstract: A method and system for producing images of at least one object of interest in a container. The method includes receiving three-dimensional volumetric scan data from a scan of the container, reconstructing a three-dimensional representation of the container from the three-dimensional volumetric scan data, and inspecting the three-dimensional representation to detect the at least one object of interest within the container. The method also includes re-projecting a two-dimensional image from one of the three-dimensional volumetric scan data and the three-dimensional representation, and identifying a first plurality of image elements in the two-dimensional image corresponding to a location of the at least one object of interest. The method further includes outputting the two-dimensional image with the first plurality of image elements highlighted.

Abstract: A method for acquiring views of an object includes acquiring a first quantity of views at a first position on a z-axis, acquiring a second quantity of views different from the first quantity at a second position on the z-axis different from the first position, and acquiring a third quantity of views equivalent to the first quantity at a third position on the z-axis different from the first position and the second position. A method is also described for processing these views to reconstruct the object.
