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 sensor system for mitigating a flame condition in a battery subject to an overcharge condition and being charged using a charging current is provided. A temperature sensor is configured to detect a temperature of at least one component of the battery, and a gas sensor is configured to detect an inflammable gas or vapor. A sensor control is configured to, when the temperature of the at least one component of the battery exceeds a pre-determined temperature threshold and when the gas sensor detects an inflammable gas or vapor, halt the charging current.

Abstract: An flight-safe indicator for a battery displays the flight-safety state of a battery to be transported by an aircraft. The indicator can be easily recognized by ground personnel anywhere regardless of the language they speak or read. The indicator comprises an icon indicating that the battery is safe for flight and would be easily recognized by personnel at an airport. The icon would be placed on the battery or on the battery packaging prior to loading on the aircraft. When the magnitude of power stored on the battery exceeds a safety threshold, the icon changes to an indication that the battery is not safe for transporting by aircraft and the operator may discharge the battery using a load until it reaches a safe level.

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.
