Abstract: A ballistic protection system combines electrical storage and/or electrical generation features, including at least one layer of material which provides ballistic protection and at least one layer of material which is electrically active.

Abstract: A system and method for ensuring the readiness of a mission critical battery in a device, the system includes a rechargeable battery as the mission critical battery disposed within the device slaved to a primary charging battery through a charge controller both of which are disposed outside of the device. The charge controller is programmed to ensure that the primary charging battery delivers a charge to the mission critical battery to maintain the mission critical battery at a charge level for maximized long term storage. The storage charge level may be 50% of the full charge level of the mission critical battery. The charge controller will receive a mission signal when the device is to be mission ready. The charge controller will then transfer the appropriate amount of stored energy from the primary charging battery to the mission critical battery to achieve full charge.

Abstract: A system for power balance monitoring in an energy storage battery comprising a plurality of energy modules connected in a series-parallel configuration. The energy storage module comprises a plurality of cells. Each module is a three-terminal module. The three terminals comprise a positive output terminal and a negative output terminal for connecting the modules in a series string to a load and an energy sharing terminal for sharing energy between modules is other battery strings. A module power management sub-system comprising a current monitoring circuit is connected to each of the energy sharing terminals. Each module power management sub-system is in communication with a battery power management sub-system so that a weak module can be detected based on module current output. Advantageously, the module power management sub-system is not connected across the main power pathway of the module and so does not appreciably increase module impedance.

Abstract: An n-phase transformer includes a core structure having a polygonal top plate and a polygonal bottom plate and n winding posts disposed symmetrically between the top and bottom plate. The primary and secondary winding loops are integrated into printed circuit boards which are then stacked over the posts in laminate fashion between the top and bottom plate.
