The cable can have an inner portion that transfers the data while an outer portion that surrounds the inner portion transfers the current.

Abstract: Various embodiments are described that relate to creating a user interface when a data structure is unknown. An application can be used to discover the content of that unknown data structure at runtime. Part of this discovery can include conversion of that data structure from a virtual machine class to a markup language. The discovered content can be used to build a user interface presented on a display. The user interface can be interactive such that information is entered into the user interface. That entered information can be retained in a database as can the discovered content. The entered information along with the content can be converted from the markup language to the virtual machine class back to an originator of the unknown data structure. This way, the originator receives a response in a format usable by the originator.

Abstract: A composition of matter including two optionally substituted phenol or optionally substituted aniline units separated by a furan spacer has been prepared. In particular, the chemical structure has a novolac bridge between the central furan ring and the two attached optionally substituted phenol and/or optionally substituted aniline units. These compounds can be modified to be used in various polymer resins. This new structure reduces toxicity relative to BPA/F, makes use of renewable chemicals, and produces certain beneficial polymer properties.

Abstract: In various embodiments, a graphical plotter can create a transformation circle. An identification component can identify a center point, a radius from the center point, and a circular outer point set extended from the center point by the radius. A creation component can create a plot based, at least in part, on the center point, the radius, and the circular outer point set. An output component can cause the plot to be outputted, where the circular outer point set is dependent on trigonometry of an angle set from an x-axis pertaining to the center point and the radius.

Abstract: An explosive reactive armor (ERA) enclosure for an ERA tile includes a bottom and a plurality of sidewalls extending from the bottom, where the plurality of sidewalls are continuous with each other and with the bottom so as to define an internal volume. The plurality of sidewalls are formed from a fiber-reinforced composite material having a plurality of plies of fiber sheet material. Additionally, a sidewall seam defined by abutting edges of the first ply is offset from a sidewall seam defined by abutting edges of the second ply. Methods of manufacturing ERA enclosures, including applying wrap layers and forming attachment structures for securing the fiber-reinforced composite ERA enclosure to an armor element, are also described. The composite enclosure is inexpensive and lightweight and improves the dynamic capabilities of armored vehicles using such ERA tiles.

Abstract: One example embodiment is a tow bar retention mechanism for a vehicle tow bar of a combat vehicle. The tow bar retention mechanism includes a tow bar retention arm, an elongated locking beam, a quick-release locking mechanism, and a quick-release safety mechanism. The quick-release locking mechanism locks the tow bar retention arm in a locked position placing the vehicle tow bar in a stowed position. The quick-release locking mechanism also unlocks the tow bar retention arm allowing the tow bar retention arm to move to an unlocked position allowing the vehicle tow bar to move to a tow position. The quick-release safety mechanism may be placed in a first position preventing the quick-release locking mechanism from moving from the locked position. The quick-release safety mechanism may also be placed in a second position allowing the quick-release locking mechanism to move from the locked position.
