Abstract: The present invention has to do with a method and system for a high precision electronic psychrometer operable at low temperatures and high humidity environments. The electronic psychrometer includes thermistors for measuring wet and dry bulb temperatures and a wicked cage surrounding one of the thermistors. The wicking action of the wicked cage is controlled by an evaporation controller in conjunction with the wick's physical parameters. The electronic psychrometer determines relative humidity and provides a readout display and/or a control signal.

Abstract: An apparatus and method for supporting a person in a bathtub or shower. The apparatus comprising: an elongated base, comprising a tapered yoke operably coupled to a first end of the elongated base and a stabilizer operably coupled to a second end of the elongated base. The apparatus comprising a rotatable and/or slidable chair, wherein the rotatable and/or slidable chair is operably coupled to the same end of the elongated base as the tapered yolk. The method comprising: providing an apparatus having a rotatable and/or slidable chair, wherein some of the components may be foldable, such as a foldable seat, a foldable back, foldable legs, and a plurality of arms. Folding the foldable components of the slidable and/or rotatable chair make transporting easier and safer because the apparatus is more compact when the foldable components are in the folded position.

Abstract: A fuel cell system that includes fuel processing components, such as a reformer and shift converter, for converting an organic fuel to hydrogen, is shut-down by disconnecting the fuel cell from its load and purging the fuel processing components of residual hydrogen with a flow of air. The purge air may be forced through the components in series or in parallel, using a blower; or, the purge air may be allowed to enter the components through a low inlet, whereupon the air rises through the components by natural circulation and exits through a high outlet, along with the residual hydrogen.
