Abstract: The instant disclosure is generally directed to low viscosity, low volatility lubricating compositions. The lubricating composition of the instant disclosure includes an oil of lubricating viscosity that contains a lubricating base oil and a hydrocarbon oil. The hydrocarbon oil makes up least 20 wt % of the oil of lubricating viscosity and has a kinematic viscosity of less than 3.7 c St at 100° C. and a NOACK volatility (measured by ASTM D5800) of less than 25 wt %. The lubricant composition further includes a polyalkenyl succinimide dispersant, and, optionally, other formulation additives. The lubricating compositions have been shown to increase fuel economy in internal combustion engines.

Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.

Abstract: Systems and methods provide for an automated system for analyzing damage and processing claims associated with an insured item, such as a vehicle. An enhanced claims processing server may analyze damage associated with the insured item using photos/video transmitted to the server from a user device (e.g., a mobile device). The mobile device may receive feedback from the server regarding the acceptability of submitted photos/video, and if the server determines that any of the submitted photos/video is unacceptable, the mobile device may capture audio descriptions regarding the insured item. To aid in damage analysis, the server may also interface with various internal and external databases storing reference images of undamaged items and cost estimate information for repairing previously analyzed damages to similar items.

Abstract: One example embodiment is an armored vehicle door quick-release mechanism includes a handle, a slide lock latch, and an actuator mechanism. The handle is coupled to the slide lock latch. The movement of the handle in a first direction causes the slide lock latch to move in a first direction to a first position so that the slide lock latch is adapted to attach the vehicle door to the actuator mechanism adapted to open and close the vehicle door. A movement of the handle in a second direction causes that slide lock latch to move in a second direction to a second position to detach the vehicle door from the actuator mechanism.

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.
