    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: In an example, a ventilator includes an outer container containing liquid, an inverted container submerged in the liquid to provide inverted container space between a closed top and an inner container liquid level; gas supply line to supply breathing gas to the inverted container space; and inhalation line having an inlet in the inverted container space to provide breathing gas to patient. The inverted container moves upward from a first elevation when the inverted container space reaches a hydrostatic delivery pressure and volume of the inverted container space increases. The inverted container stops moving upward and the gas supply line stops supplying when the inverted container reaches a second elevation above the first. Based on a breath demand signal or preset timing, the inhalation line opens to permit flow of breathing gas to the patient at the hydrostatic delivery pressure, lowering the inverted container due to lost buoyancy resulting in sinkage.

    Abstract: In an example, a respirator includes a respirator body having a distal portion and a proximal portion, the distal portion including a filter housing wall and an open distal end. The proximal portion includes a facial interface which is compliant and deformable from an undeformed state to a deformed state to conform to a facial contour of an individual. One or more filter frames are inserted into the distal portion and supported by the filter housing wall to separate filter media on opposite sides of at least one of the one or more filter frames. A filter cover is releasably attached to the open distal end to enclose the one or more filter frames and filter media, forming a filter housing. The one or more filter frames are removable from the distal portion and replaced into the distal portion to allow replacement of the filter media.
