Abstract: A method for predicting time-to-failure and remaining-life of an electrical power system asset includes analyzing characteristics of the power system asset over a specified time interval; based on the analysis, associating the power system asset with a pool of similar power system assets having similar historical performance characteristics; and based on the association, calculating time-to-failure and remaining-life probability factors for the power system asset. A computer program product is also provided for carrying out the method, and the method may further include a mechanism whereby the computer program learns ways to modify and enhance the analysis of the performance characteristics to provide for higher confidence levels in time-to-failure and remaining-life probability calculations.

Abstract: An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle.

Abstract: An exemplary valve control system includes a master controller that wirelessly communicates with a plurality of slave controllers. The slave controllers are each associated with respective devices and sensors. In exemplary arrangements a valve slave controller is associated with a motor that controls a condition of a valve. An exemplary control valve includes a valve body with a plurality of ports (A, B, C, D, E, F) and a plurality of annular flow passages. A piston is selectively movable within a bore within the valve body through operation of the motor and valve slave controller. The valve slave controller is selectively operative to control the position of the piston so as to selectively enable liquid flow through the valve.

Abstract: A device, which may be embedded in a power distribution enclosure, enables analysis of the conditions of an electromechanical machine operating on a commonly supplied network with other electromechanical machines. The analysis preferably uses aggregate operating voltage and current signals supplied to or from such machines along with known changes in steady-state conditions of one or more machines to discern the discrete effect of one or more machines to the aggregate electrical signal. Such discrete effect can then be associated with the operating performance of the individual machine. And, since such voltage and current signals are normally readily available at the enclosure, wiring or any other communication means to any sensors on the electromechanical machines or devices are not necessary. The embedded device may optionally receive or transmit information to a computing or monitoring device remote from the enclosure.

Abstract: Fuel cell gas sensors using an aperture in a fuel cell gas sensor that allows for determination of a gas proportion in a sample that includes more gas than could otherwise be safely sampled. The aperture is adjustable between an open and a closed state. The amount of the gas of interest exposed to the fuel cell may be adjusted by adjusting the amount of time that the aperture is in the open state. Alternatively, the amount of the gas of interest exposed to the fuel cell may be adjusted by adjusting the size of the aperture.
