Abstract: An energy conversion system, comprising: a reservoir container including at least two chambers of inversely variable volume for respectively storing a quantity of fuel and receiving a quantity of exhaust; a means for decreasing the volume of the first chamber while concurrently increasing the volume of the second chamber; at least one energy conversion device; first means for communicating fuel between the at least one energy conversion device and a first of the chambers in the reservoir container; and second means for communicating exhaust between the at least one energy conversion device and a second of the chambers in the reservoir container. The reservoir container may be transported to a recharging/refilling station or recharged in-situ. A particular application for metal-air fuel cell power systems is shown and described.

Abstract: A Horizontal and Vertical Gaze Nystagmus test apparatus and method for detecting eye twitch of an impaired test subject, the apparatus being generally comprised of a target having a top end for the test subject to focus on and follow with at least one eye through a horizontal range of motion extending between a leftmost location and a rightmost location relative to a central transverse axis, and a through a vertical range of motion, the apparatus further including a base forming a template and support for the target, where the base includes means for positioning thereof relative to the face of the test subject and means for prescribing a uniform travel path for the target between the leftmost and rightmost locations, and the aforementioned vertical range of motion at a specified distance from the face of the test subject.
