摘要： A regulated DC power supply facilitates extended and uninterrupted power to a load by using a secondary power source such as a regenerative fuel cell that has its DC power output conditioned by a power converter. The DC power supply includes a rectifier that converts AC power from an AC power source to DC power for a load coupled to a DC bus. A fuel cell arrangement is electrically coupled to a power converter that is coupled in turn to the DC bus, the converter conditions an unconditioned DC power output of the fuel cell to the load. A system controller is communicatively coupled to the rectifier, the converter and to a fuel cell controller, the fuel cell controller initiating DC power output from the fuel cell arrangement upon detecting the AC power outage (or disengaging the fuel cell upon resumption of AC power).

摘要： A new and improved learning system that contains a highly interactive environment rich with educational information. The new and improved learning system contains an interactive educational software program with a companion hands-on educational activities kit. The learning system includes software which guides the user through activities, instructions, and educational material. The program's virtual expert explains material. The program also consists of several virtual machines that the user interacts with. One virtual machine holds readily accessible entertaining and scientific facts; another holds a readily accessible glossary of scientific terms. There is also a virtual machine that functions as a laboratory journal for user input of desired observations and measurements. At the completion of the project, the software compiles the user's information into an accessible final report for reading and printing. The kit is a seed growing kit with which the user experiences plant germination, anatomy, photosynthesis, and other relating educational concepts firsthand. With the help of the virtual expert, the user steps through a sequence of activities timed with plant growth. The activities generally last one to two weeks. The software delivers the necessary instructions and information for the user to successfully grow the seeds in the kit, access related facts, and input and compile observations and measurements during the learning process. The present invention has the potential for abundant educational information available from the software, the kit provides for thorough hands-on interaction with the subject, and the user is fully in control of the learning process as no supervision is necessary.
