Abstract: A vehicle-mounted carrier for transporting equipment, such as bicycles, includes a hitch receiver engagement portion having a hitch engagement member engageable with the hitch receiver, and an equipment support portion pivotably interconnected with the hitch receiver portion. The equipment support portion includes a mast defining upper and lower ends, an extension member that is movable between lowered and raised positions, a drive arrangement for selectively moving the extension member between the lowered and raised positions, and an equipment support arrangement carried by the extension member. The equipment support arrangement is movable via the drive arrangement between lowered and raised positions upon movement of the extension member between the lowered and raised positions.

Abstract: A waste collection cart assembly for collecting waste material from a suction line during a medical procedure. The waste collection cart assembly includes a housing having a top portion defining a work surface. A waste container is coupled to the housing for collecting the waste material from the suction line. A manifold receiver defining an opening is coupled to the waste container. A manifold having a specimen trap is received within the opening of the manifold receiver. A vacuum source is coupled to the waste container. The vacuum source provides a vacuum on the waste container to draw the waste material from the suction line through the manifold and into the waste container. The specimen trap collects a specimen from the waste material while being drawn into the waste container. The specimen may be transferred to a specimen container disposed on the work surface.

Abstract: According to at least one aspect, a fluid flow monitoring system includes an ultrasonic sensor for generating measurement signals associated with respective ultrasonic signals propagating through the fluid in the lumen, a shut-off valve for blocking fluid flow in the lumen, and a controller. The controller can be communicatively coupled to the ultrasonic sensor and to the shut-off valve. The controller can be configured to compute a plurality of fluid flow parameter estimates based on a plurality of measurement signals generated by the ultrasonic sensor over a time window while the shut-off valve is open. The controller can obtain an offset value associated with fluid flow parameter measurements during a zero flow state of the shut-off valve. The controller can then check for presence of a fluid leak event based on the fluid flow parameter estimates over the time window and the offset value.

Abstract: A bicycle frame assembly having a number of rotatable members configured to absorb shocks and impacts associated with operation of the bicycle. The assembly includes a frame constructed to support a rider and a chain stay having a rearward end that extends toward a wheel hub and a forward end that is pivotably connected to the frame. An absorber is pivotably connected to the forward end of the chain stay and extends to a rocker arm that is pivotably connected to the frame. A seat stay is pivotably connected to a rearward end of the rocker arm and extends to the rearward end of the chain stay. The rearward ends of the seat stay and the chain stay are pivotably connected to rotate about a common axis.
