Abstract: The present application discloses a system and method for monitoring and reporting the status of a direct current (DC) subsystem including a battery bank and battery charger. The system and method are configured to perform tests on distinct modules within the DC subsystem and store test data. The test data are analyzed to determine the status of each module. An aggregator determines the DC subsystem status based on the module statuses and displays an indication of the determined aggregate status.

Abstract: A mobile power supply housed within a wheeled trailer which can be towed to various locations, particularly remote locations, for providing electrical power as needed for operating equipment or for charging of batteries or other electrical supply devices at such remote locations. The apparatus includes a unique trailer design including venting means for preventing the accumulation of hydrogen normally associated with high power battery operation, particularly charging thereof and therewith, by monitoring hydrogen at all times within the trailer interior and selectively passively and actively venting the interior environment when hydrogen levels are high or whenever necessary. A unique roof design is included for gathering hydrogen near the upper portion of the interior roof construction adjacent to a venting outlet to facilitate expelling thereof.

Abstract: Enclosure for holding an electrical device with dual access panels for safely limiting access to the device while allowing maintenance thereof. The housing defines an access opening with a limited accessing construction thereover. Interior and exterior panels are included each movable to be closed and opened. The interior panel is preferably transparent to facilitate viewing therethrough. The exterior panel is preferably metal and is hinged to the housing for movement between closed and opened positions. Individual accessing apertures can be defined in the interior and exterior panels to allow localized access by servicing personnel. Specific positioning of the access opening in the interior and/or exterior panels provides access to limited areas of the electrical device within the housing and prevents access to other areas for safety. The interior panel can have indicia imprinted thereon to facilitate servicing.

Abstract: A stationary building structure having a sidewall opening with a shuttle section movable through the opening to an extended position or movable over the opening for closing thereof. The shuttle section includes a frame which defines a shuttle floor surface thereabove. A shuttle tail extends from the shuttle frame into the stationary building structure for supporting the shuttle section at all times whether in the extended position, the retracted position or moving therebetween. An outer shuttle wall extends upwardly from the frame for closing the sidewall opening of the stationary building when the shuttle is retracted. A sealing means is defined on the outer wall for engaging the building around the sidewall opening for selectively sealing thereof when in the retracted position. A drive mechanism is mounted to the stationary building structure and is operatively secured to the shuttle section for urging movement thereof between the respective positions.
