Abstract:
A dry powder inhaler incorporates a cyclone chamber (4) comprising at least one air inlet (6) and an outlet (10) wherein the configuration of the air inlet (6) and the shape of the chamber (4) is such that in use a reverse flow cyclone is set up in the chamber (4). The chamber (4) further comprises flow disrupter means, e.g. the upper surface (14) of a protrusion (12) from the base, disposed so as in use to restrict air flowing from the base of the chamber (4) in an axial direction.
Abstract:
A system is disclosed that provides a goal based learning system utilizing a rule based expert training system to provide a cognitive educational experience. The system provides the user with a simulated environment that presents a business opportunity to understand and solve optimally. Mistakes are noted and remedial educational material presented dynamically to build the necessary skills that a user requires for success in the business endeavor. The system utilizes an artificial intelligence engine driving individualized and dynamic feedback with synchronized video and graphics used to simulate real-world environment and interactions. A robust business model provides support for realistic activities and allows a user to experience real world consequences for their actions and decisions and entails realtime decision-making and synthesis of the educational material. The system is architectured around a table of components to manage and control the system.
Abstract:
A battery cooling system (100) is provided to maintain more uniform temperature distribution in vehicle batteries (142). A battery (142) is provided with at least one exposed cell surface (143). A cooling shell (146) is provided with an interior surface spaced apart from the exposed cell surface (143). The interior surface defines a flow channel (147) for cooling fluid (150) such as air (114) provided by a system fan (112), and the air (150) flows in direct contact with the cell surface (143) from an inlet to an outlet of the channel (147). The channel (147) has a first hydraulic diameter at the inlet that is greater than a second hydraulic diameter at the outlet to the channel (147). The hydraulic diameter is varied or decreased along the length of the channel (147) such that the system provides a first surface heat transfer coefficient proximate to the channel inlet that is less than a second surface heat transfer coefficient proximate to the channel outlet.
Abstract:
The invention relates to the use, for filtering one or more particle-laden fluids, of at least one hollow element obtained by the winding in touching and/or non-touching turns of a wire (F) of cross section (s), said hollow element having at least one closed end and a [free area (Sfree)/area occupied by the wire (Sm)] ratio of between 2 and 50%.
Abstract:
The invention concerns an inner tray, arranged inside a chamber, comprising a plurality of parallel beams (1), located in a common horizontal plane and fixed through their ends to the wall of the chamber, and, between said beams and supported thereby, rows of adjacent rectangular plates (2), completely covering the space between the beams. The invention is characterized in that the supporting edges (3) of the plates (2) through which the latter are supported on the beams (1), are folded downwards by two substantially right-angled folds, and in that each of the edges (4) of the plates (2), perpendicular to the beams (1) is folded so as to form a female part (4a) or a male part (4b) capable of being respectively nested in a male (4b) or female (4a) part formed by the folded edge of the adjacent plate. The invention also concerns a chamber containing such a tray.
Abstract:
A system and method for printing on media includes a printhead assembly, a memory, and a controller. The printhead assembly is configured to make physical print sweeps relative to print regions of the media and to print within the print regions during the physical print sweeps. The memory communicates with the printhead assembly and is configured to receive data associated with a logical print sweep. The data associated with the logical print sweep controls printing within a first print region of the media during a corresponding first physical print sweep. The controller communicates with the printhead assembly and memory. The controller initiates the first physical print sweep of the printhead assembly before all of the data associated with the logical print sweep is received by the memory.
Abstract:
A monitoring system with dynamically configurable non-interfering signal processing is disclosed. In one aspect, data relating to the management of the operation of a machine and data relating to the safety protection of the machine are combined in a non-interfering manner.
Abstract:
Dry powder inhalers include radially-extending discrete, typically dose-specific, airway channels serially forming a portion of the inhalation pathway to deliver dry powder to a user using the inhalers.
Abstract:
A method of operating a computer system includes storing, in the computer system, a database containing performance measure data regarding performance measures of a plurality of items. The method further includes inputting into the computer system a plurality of performance measure constraints. The method also includes modeling the performance measure constraints with a set of equations. The equations include a plurality of variables. Each of the variables corresponds to a respective one of the items. Each variable is, for example, to be assigned either the value “1” or the value “0”. The value “1” may represent a recommendation to take an action relative to the corresponding item in the portfolio and the value “0” may represent a recommendation to take another action. The computer system is used to solve the set of equations to generate one or more solutions that satisfy the performance measure constraints.
Abstract:
The invention relates to a vehicle occupant sight testing assembly. The vehicle occupant sight testing assembly comprises a vehicle stopping area on or adjacent a road, a sight testing means (12) on or adjacent the road, and a vehicle barrier (14) arranged adjacent the vehicle stopping area.
