Abstract: A device to determine density includes a housing, a first transducer disposed in the housing at a first position, and a second transducer disposed in the housing at a second position. The second transducer is located a distance from the first transducer. The device also includes a controller that reads a first output from the first transducer, and reads a second output from the second transducer. The controller determines a density of a liquid based on the first output, the second output, and the distance.

Abstract: Examples are directed toward systems and methods relating to collecting and analyzing samples. For example, a system includes a cold trap that directly collects a sample. The cold trap operates to serve as a collection filter while the system draws in a flow across the cold trap. A thermal heater, coupled to the cold trap, flash heats the cold trap to produce a released sample from the cold trap at a release concentration. An analyzer entrains the released sample at the release concentration into a sampling flow of the analyzer for analysis.

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: Embodiments are directed to systems and methods for delivering and displaying reconfigured media inputs with uniform and standardized user interfaces and functionality across different video players. One embodiment is directed to a method of interfacing with a plurality of video players comprising receiving a first media input associated with a first video player from a first content delivery network of a plurality of content delivery networks. The method further comprises receiving a reconfigured media input from a reconfigured media provider computer and loading the first video player on the user computer. A master platform may then generate a request for a time indicator, translate the request for the time indicator using first translation instructions associated with the first video player, send the translated request for the time indicator to the first video player, receive the time indicator, and perform one or more actions based on the received time indicator.
