Abstract: Embodiments include an optical system comprising a plurality of powered optical elements, arranged within a same optical path, configured to simultaneously pass and focus therethrough mid-wave infrared (MWIR) and long-wave infrared (LWIR) spectral bands to a focal plane array (FPA) and provide simultaneous correction of monochromatic and chromatic aberrations over the MWIR and LWIR spectral bands with a low f-theta distortion. The plurality of powered optical elements comprises a first set of powered lenses having a passive athermalized response over fluctuating temperatures in a variable temperature environment; and a second set of powered lenses to operate in a constant cryogenically cooled environment. A method and a situational-awareness device are also disclosed.

Abstract: A system for making high voltage measurements to measure a voltage of a battery pack and detect of an isolation fault. The system includes a first resistive divider comprising at least a first resistive element and a second resistive element. The system also includes a second resistive divider comprising the second resistive element and a third resistive element. The system also includes a plurality of switches comprising a first switch and a second switch coupled between the second resistive element and the battery pack. The system further includes a controller configured to control the plurality of switches to operate in first mode to measure the voltage of the battery pack based on a voltage produced by the first resistive divider, and to control the plurality of switches to operate in at least a second mode to detect an isolation fault based on a voltage produced by the second resistive divider.

Abstract: An improved storage unit of the type having an interior surface, an exterior surface, a floor, a pair of side walls, a front wall, a rear wall, and a roof. The roof is translucent, attaches without any puncturing thereto, and has overhanging eaves and bows with centers that are bowed thereat. A ventilation system allows the storage unit to benefit from storing in a climate controlled warehouse and provides airflow when the storage unit is stored outside. The rear wall has a roll-up door. The pair of side walls, the front wall, and the rear wall are attached from the exterior surface and the interior surface is smooth and non-abrasive. The floor is plastic undercoated plywood. Towing brackets front and rear provide a safe, strong, and secure method to attach a winch system of a transport system for maneuvering the storage unit on and off the transport system and to maneuver the storage unit with forklifts or pallet jacks in a yard or warehouse.

Abstract: A stacking pocket for disposing at a corner of a roof of a shipping container and for holding a caster wheel of an above-stacked shipping container. The pocket includes flat bars, a plate, and a wheel. The plate is triangular-shaped to substantially conform to the corner of the roof of the shipping container, attaches to the corner of the roof of the shipping container, and has a periphery. The flat bars are disposed in a truncated triangular configuration forming an open apex about the periphery of the plate, are attached to the plate, and hold the caster wheel of the above-stacked shipping container therebetween. The wheel is horizontally rotatably attached to the plate and is disposed at the open apex of the flat bars.
