Abstract: A two-piece snap-on magazine adapter for a handgun. This magazine adapter provides a relatively continuous surface between the handgun and locked extended length magazine to afford the handgun user with a comfortable grip among other benefits. In the preferred embodiment, the magazine adapter has two snap together pieces: a main body and an end cap. The main body has an interior pocket configuration contoured to capture the magazine floor plate. The main body of the device is then captured by an end cap that locks via a detent mechanism onto the main adapter body. The magazine adapter fits completely around the magazine such that when the magazine is locked into the handgun, the resulting grip provides a smooth, continuous and comfortable fit between the extended length magazine's floor plate and the butt of the handgun's grip.

Abstract: Apparatus for reminding a person to perform a plurality of periodically repeating tasks includes a first and a second user-accessible interface each having at one least task switch. A first and a second signal device each correspond to the respective first and second user-accessible interfaces. A surface supported by the apparatus can be imprinted with first and second task identifications which are aligned proximate to the corresponding signal devices and user interfaces. The apparatus includes an electronic processor configured to set a first alarm interval and a second alarm interval in response to the at least one task switch of the respective first or second user-accessible interface being accessed by a user a single time. The processor measures the passage of time using an electronic timing device and activates the first or second signal device when the measured passage of time exceeds the respective first or second alarm interval.

Abstract: A proton exchange membrane fuel cell power system for producing electrical power is described and which includes a plurality of discrete fuel cell modules having at least two membrane electrode diffusion assemblies, each of the membrane electrode diffusion assemblies having opposite anode and cathode sides; a pair of current collectors are individually disposed in juxtaposed ohmic electrical contact with opposite anode and cathode sides of each of the membrane electrode diffusion assemblies; and individual force application assemblies apply a given force to the pair current collectors and the individual membrane electrode diffusion assemblies. The proton exchange membrane fuel cell power system also includes an enclosure mounting a plurality of subracks which receive the discrete fuel cell modules. Additionally, a control system is disclosed which optimizes the performance parameters of the discrete proton exchange membrane fuel cell modules.

Abstract: A device and method for collecting a representative sample of hazardous fluid from a drum, and then disposing of the sampler, without ever removing the sampler from the drum so as to safeguard the operator from exposure to the hazardous fluid. The collected sample is moved, by a slidable plunger, along the inner channel of a hollow tube toward a drainage opening maintained at the top thereof while the bottom of the tube remains immersed within the tank. A break-apart construction of the sampler thereafter enables separation between its immersed and emergent portions, while the tube remains immersed, to safeguard the operator after sampling has been completed by enabling permanent disposal of the separated portions in the drum being sampled. An irreversible plunger movement feature discourages any attempt to reuse the sampler.
