Abstract: Embodiments of a continuous dust accumulation monitoring system comprise an enclosure adapted for use in electrical hazardous locations, a sample area for collecting ambient dust, a dust accumulation sensor assembly installed in the enclosure configured to generate a signal based on the amount of ambient dust collected on the sample area and a circuit board within the enclosure configured to receive the signal from the dust accumulation sensor assembly. The continuous dust accumulation monitoring system may be connected to system control hardware.

Abstract: Imaging devices for identification of target regions are generally described. Medical ultrasound is a popular medical imaging modality primarily used for diagnostic imaging of soft tissue but also for interventional procedures such as guidance of a needle or catheter placement. Examples include diagnostic imaging of organs, such cardiac or liver strictures. Common interventional procedures that rely on ultrasound guidance are central line placement and guidance of nerve blocks, both of which are high volume procedures in certain hospital settings such as the intensive care unit (ICU).

Abstract: A lifting mechanism for a storage bin is positioned in a cabinet having a countertop. The lifting mechanism has a base adapted to be supported in the cabinet, a moveable member operably connected to the base, a support member connected to the moveable member, and a storage bin supported by the support member. The moveable member is moveable between a first position, wherein the storage bin is adapted to be positioned within the cabinet, and a second position wherein the storage bin is raised such that the storage bin is adapted to be positioned out of the cabinet. When the storage bin is raised, a top of the storage bin is adapted to be positioned proximate the countertop.

Abstract: Dry powder inhalers for dispensing pharmaceutical grade formulations of inhalable dry powder include: an inhaler housing having a mouthpiece associated therewith; and a slidably extendable forward member that is movable between retracted and extended positions, held by the inhaler housing adjacent the mouthpiece. In the extended position, the forward member extends outward a distance beyond a forwardmost portion of the mouthpiece, and in the retracted position, a forwardmost portion of the forward member is positioned rearward of the forwardmost portion of the mouthpiece with an access portion of the mouthpiece accessible by a user.

Abstract: Dry powder blister packages include sealed blisters with a piezoelectric active layer that flexes to vibrate the dry powder in a blister to facilitate active dispersion.

Abstract: Dry powder inhalers with a multi-dose dry powder package for dispensing pharmaceutical grade formulations of inhalable dry powder, include: (a) a blister package comprising a plurality of spaced apart sealed blisters thereon, each blister having a projecting ceiling and a floor defining a blister channel therebetween, the blister channel comprising a dry powder therein; (b) a movable blade cartridge holding a blade at a forward portion thereof; and (c) an extendable mouthpiece attached to the movable blade cartridge. In operation, a user pulls the mouthpiece outward and then pushes the mouthpiece inward to cause the blister package to advance to position a blister in a selected dispensing position in the inhaler and to cause the blade cartridge to move the blade across a blister ceiling held in the dispensing position in the inhaler to thereby open the blister held in the dispensing position.

Abstract: A flat bed cart includes a molded resin load carrying bed having longitudinally spaced ends, a generally planar upper side and a bottom side that includes a plurality of ribs, a pair of spaced, longitudinally extending slots and first, second and third sets of integrally molded fastener mounted pads that are located adjacent the first and second ends of the bed and intermediate the ends respectively. The slots receive a pair of longitudinally extending reinforcing bars that carry at their ends upright handle receiving mounts. The handle receiving mounts include members arranged in recesses spaced about the periphery of the bed at the first and second ends thereof. At least one handle is provided which is adapted to be selectively positioned within a respective pair of the upstanding handle receiving mounts.
