Abstract: Apparatus and methods for training a person in route management are based on a personal computer. The apparatus may be used for example to train a bus driver to follow a new or changed route. A data store stores data streams corresponding to different kinds of information of the route, including video of the route, audio data, sound data, GPS and time data, and vehicle engine management data. A VDU and loudspeaker are used as output devices to present the plurality of data streams to a user such that they are co-related to the route to be followed. Data streams corresponding to different route information are not combined in the data store, but comprise cross-referable data. The computer is programmed to present the first data stream and the further data stream in a co-related manner via the output devices and in dependence upon the cross-referable data.

Each pocket has an open end opening towards an airflow stream to be guided. Each rib is configured with an inwardly extending length selected to correlate with a boundary of a low-loss airflow glide path. The air pillows operate to guide the airflow stream along the low-loss airflow glide path with reduced airflow stream turbulence and airflow pressure loss.

Abstract: An improved nebulizer places a venturi in a rainfall chamber and in close proximity to or inside a patient's oral cavity. One or more medicine feed lines feeds the medicine to a location proximate to a venturi. The rainfall chamber contains a sump communicating with the venturi for collecting medication not delivered to the patient and for recycling that medication for delivery to the patient. A medicine receiver may be pre-filled with a standard unit dose of medication.

Abstract: An improved nebulizer places a venturi in close proximity to or inside a patient's oral cavity. One or more medicine feed lines feeds the medicine to a location proximate to a venturi. A plurality of medicines may be administered simultaneously to the patient, with preferably each medicine vial being shape-keyed to a medicine receiver of corresponding shape. The medicine vial or vials may contain a standard unit dose of medication. A portable gas canister can be utilized to supply air pressure to the venturi when a press open release closed type valve is actuated.

Abstract: A connector assembly includes first and second hoses, a tubular connector, and a clamp. The tubular connector includes first and second radial projections that are spaced apart along an axial direction of the tubular connector. The tubular connector extends into the first hose, and the first radial projection of the tubular connector engages with the inner surface of the first hose. The tubular connector also extends into the second hose, and the second radial projection of the tubular connector engages with the inner surface of the second hose. The first hose extends into the second hose so that the first and second hoses axially overlap in an area between the first and second radial projections of the tubular connector. The clamp engages the outer surface of the second hose in the axially overlapping area of the first and second hoses to clamp the first and second hoses to the tubular connector.

Abstract: A method for generating a high-velocity cutting jet comprises forming a high velocity jet of a liquid such as water, forming a suspension of an abrasive such as garnet in a carrier gas containing a condensable vapour such as superheated steam, and entraining the abrasive suspension into the liquid jet so that the vapour condenses, producing a cutting jet of a liquid/abrasive mixture. A cutting head of apparatus for generating the cutting jet has a chamber into which the abrasive suspension is passed. The liquid jet traverses this chamber, entraining the suspension, and passes into a tapering transition region and a bore of a nozzle. Kinetic energy is transferred from the liquid jet to the abrasive as they pass trough the chamber and the nozzle. Condensation of the vapour ensures that the cutting jet leaves the nozzle at close to ambient pressure, reducing the diameter of the cutting jet compared to conventional abrasive-in-air systems, so as to increase the energy density of the abrasive.
