Abstract: A method for increasing workable power output and run time duration of a battery backup system is disclosed. A plurality of battery groups is provided. A microprocessor electrically connects the power output of a first battery group and a second battery group to a UPS. The microprocessor monitors the output voltage of the first and second battery groups. When the monitored output voltage of the first and second battery group falls below a predetermined level, the microprocessor electrically disconnects from the UPS the first battery group and electrically connects to the UPS the power output of another of the plurality of battery groups. The first battery group is configured to be re-connectable to the UPS after a time period equal to or greater than necessary to permit the output voltage of the first battery group to recover to about its nominal voltage rating.

Abstract: An automatically re-configurable solar array apparatus is disclosed. The apparatus includes a solar array electrically connected to an inverter through a power switch controlled by a microprocessor. The solar array comprises a combination of solar panel strings wired in parallel. Each solar panel string comprises a plurality of solar panels wired in series. An output electrical parameter level of the combination of solar panel strings is capable of producing output power from the inverter. The output electrical parameter level of the combination of solar panel strings is equal to about a predetermined electrical parameter level under sunny conditions. The solar array is pre-wired to permit microprocessor-controlled switching to reconfigure the array into solar panel strings of varying lengths. The electrical parameter level is at least one of a voltage level, a current level, and a power level.

Abstract: A sprocket assembly for a vehicle includes a sprocket hub with an interchangeable sprocket ring. The sprocket hub includes a plurality of outwardly extending flanges and means for mounting the sprocket hub to the vehicle. The sprocket ring includes a plurality of outer spaced teeth extending outwardly from the sprocket ring for engaging a drive loop of the vehicle. The sprocket ring further includes a plurality of inwardly extending flanges, each inwardly extending flange is configured to interface with a corresponding outwardly extending flange of the sprocket hub. The sprocket ring is aligned and laterally secured to the sprocket hub by a plurality of removable fasteners. The sprocket ring is one of a plurality of interchangeable sprocket rings that can be mounted on the hub. Each sprocket ring can be configured differently to provide different levels of power transfer suitable for different track conditions.

Abstract: A fluid collection and drainage pan is provided for collecting fluids such as oil drained from engine components and the like placed in the pan. The drainage pan is mountable directly on top of the inlet end of a variety of standard capacity fluid storage drums or barrels and provides for the direct flow into the drum of fluid drained into the pan.
