Abstract: Embodiments are directed to techniques for interacting with a hierarchical video segmentation using a video timeline. In some embodiments, the finest level of a hierarchical segmentation identifies the smallest interaction unit of a video—semantically defined video segments of unequal duration called clip atoms, and higher levels cluster the clip atoms into coarser sets of video segments. A presented video timeline is segmented based on one of the levels, and one or more segments are selected through interactions with the video timeline. For example, a click or tap on a video segment or a drag operation dragging along the timeline snaps selection boundaries to corresponding segment boundaries defined by the level. Navigating to a different level of the hierarchy transforms the selection into coarser or finer video segments defined by the level. Any operation can be performed on selected video segments, including playing back, trimming, or editing.

Abstract: A drop-in treatment apparatus and system for PFAS-impacted liquids. The drop-in treatment apparatus and system may comprise one or more cartridges having a plurality openings; one or more mesh containers disposed within the one or more cartridges; one or more tethers; a submersible pump coupled to the cartridges via the tethers; and a power source electrically coupled to the submersible pump. The drop-in treatment apparatus may further comprise a plurality of prescribed masses of sorbent or resin filled within the mesh containers, such that the prescribed masses of sorbent or resin are disposed within the cartridges. The prescribed masses of sorbent or resin may be configured to remove PFAS compounds from a liquid and may be in the range of 0.1-50,000 milligrams per milliliter of liquid volume to be treated. The sorbent may be pyrogenic carbon, granular activated carbon, biochar, zeolite, aluminosilicates, and combinations thereof.
