Abstract: According to one aspect, a method includes obtaining a command on a vehicle, the command being arranged to identify a first action to be taken by the vehicle, wherein the vehicle is in a first vehicle state and the command has a first command state. The method also includes determining, on the vehicle, whether the first command state is consistent with the first vehicle state. When it is determined that the first command state is consistent with the first vehicle state, the method includes executing the first command. When it is determined that the first command state is not consistent with the first vehicle state, the method includes identifying the first command as an illegitimate command and ignoring the illegitimate command.

Abstract: Motorized door assemblies having a door pivoting about a pivot axis extending across opposing jambs. In one aspect, the assembly includes a motor assembly having a motor, drive gears, slip clutch, and driven shaft connected to the door to pivot it about the pivot axis. The slip clutch includes a clutch plate slideable along the driven shaft, a drive plate driven by the motor via the drive gears, and a clutch spring urging the clutch plate into engagement with the drive plate, where the clutch and drive plates have profiled and counter-profiled faces. In another aspect, a break beam emitter and receiver are mounted to respective ones of the opposing jambs along a beam axis extending parallel to the pivot axis and proximate to an edge of the door opposite the pivot axis. Interruption of a light beam projected therebetween alters operation of a motor assembly.

Abstract: Provided herein are devices, systems, and methods for providing respiratory therapy to a patient using a nasal cannula comprising a cannula body, first and second inlet tubes, and a nasal prong for the delivery of a flow of breathing gas to the patient. Configured with the cannula is a nebulizer having an aerosol generator positioned to emit aerosolized medicament along a longitudinal axis of the nasal prong. A flow director is configured to direct the flow of breathing gas into the nasal prong such that the breathing gas flows along the longitudinal axis, such that the flow of aerosolized medicament is contained within the flow of breathing gas as it moves along the longitudinal axis of the nasal prong for delivery to the patient.

Abstract: Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfectants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

Abstract: Systems and methods for providing respiratory therapy are disclosed. The system includes a nebulizer operable to aerosolize a medicament, a cylindrical mixing chamber, an impacting cap and a recirculation tube. The mixing chamber has an inlet port, an outlet port, an aerosol port in fluid communication with the nebulizer, and a drainage port. The inlet port receives a flow of breathing gas. The mixing chamber receives the aerosol via the aerosol port, entrains aerosol into the flow of breathing gas, and delivers the breathing gas entrained with aerosol to the outlet port. The impacting cap receives and coalesces a portion of the aerosol into droplets within the space defined by the mixing chamber and the impacting cap. The mixing chamber is also configured to direct rain-out resulting from the droplets to the drainage port. The system also includes a recirculation tube to return the rain-out to the nebulizer.

Abstract: Described are fluid pumping and fluid handling systems, which may be suitable for use in medical devices, such as artificial or extracorporeal blood pumping systems. The systems can include a dual housing configuration for pneumatic actuation comprising a main housing containing a pump cassette comprising a pneumatically actuated pump and pneumatically actuated valves. The pump can include a pump actuation chamber and pump pneumatic port, and the valves can each include a valve actuation chamber and valve pneumatic port. Connecting tubes can be used to fluidly connect the pump actuation ports and valve actuation ports to a tube-support housing having a first side receiving one end of each connecting tube and a second side providing a pneumatic interface arranged to connect to an array of pneumatic receptacles on a base unit of the system to facilitate easy, compact and accurate pneumatic interconnection between the pump cassette and the base unit.

Abstract: Systems and methods for determining a presence of cargo within a container are described. The determination may comprise transmitting a first electromagnetic signal within the container and receiving a first reflected electromagnetic signal corresponding to the first electromagnetic signal. The first reflected electromagnetic signal may be converted into a set of first magnitude values corresponding to a set of bin values representing a respective distance from the radar device. The first magnitude values may be integrated, using a moving window, over successive subranges of bin values to produce a set of integrated magnitude values. A set of integrated base magnitude values may be subtracted from the set of integrated magnitude values to produce a set of normalized integrated magnitude values. A presence of cargo within the container may then be determined by comparing each of the normalized integrated magnitude values with corresponding threshold values.

Abstract: A cannula for providing respiratory therapy to a patient includes a first nasal prong having a proximal end attached to a cannula body and a distal end for insertion into a nare of the patient. The first nasal prong defines a lumen for a flow of breathing gas from a source of breathing gas to the nare of the patient, and the first nasal prong has a variable geometry such that a cross-sectional area of the lumen at the distal end of the first nasal prong varies with a flow rate of the breathing gas. Varying the cross-sectional area of the first nasal prong lumen with the flow rate of the breathing gas enables the first nasal prong to maintain a high velocity flow to the nare for effective flushing of the patient's airway.
