Abstract: A dressing for wounds includes a useful material, such as dye or biocide, trapped within or behind a gelatin barrier. On application to a wound, metalloproteinases naturally present in the wound diffuse into the dressing and degrade the gelatin, releasing the trapped material. The released material serves various useful purposes, such as indicating the status of the wound or improving wound healing.

Abstract: A method for operating a switched reluctance electrical generator in a manner that is highly efficient involves initially performing a mapping technique to obtain data relating to all of the possible operating conditions of the generator system that generate the desired output power. This mapping technique can be performed empirically or by computer simulation. Then, the effective phase currents supplied to the windings on the stator are measured or calculated. Next, the optimum conduction angles can be selected as those turn-on angles and turn-off angles that occur using the smallest effective phase currents supplied to the windings on the stator. Lastly, the generator system is operated using the selected optimum turn-on and turn-off angles. If desired, a feedback loop can be provided for comparing the actual output power that is generated by the generator system with a desired reference output power level to insure that such actual output power is maintained at or near the desired output power.
