In an embodiment, an energy-absorbing device can comprise: a polymer reinforcement structure, wherein the polymer reinforcement structure comprises a polymer matrix and chopped fibers; and a shell comprising 2 walls extending from a back and forming a shell channel, wherein the shell comprises continuous fibers and a resin matrix; wherein the polymer reinforcement structure is located in the shell channel.

A military vehicle including an engine coupled to the chassis for providing mechanical power to the military vehicle, a motor/generator coupled to the engine, and an energy storage system including a battery electrically coupled to the motor/generator. The military vehicle is operable in a silent mobility mode with the engine inactive and the energy storage system providing power to the motor/generator to operate the military vehicle. The motor/generator and the battery are sized such that electrical power generation through engine drive of the motor/generator is greater than the power depletion through operation of the military vehicle in the silent mobility mode. The motor/generator can charge the energy storage system while the military vehicle is driving or stationary.

A cleaning device for a surface, such as a windshield of a vehicle, has a housing that holds a spray bar, rotatable brush and a wiper blade. An engagement mechanism moves spray bar, the brush, and the wiper blade out from a disengaged position within the housing to an engaged position outside the housing so that they can be used to clean, brush, and dry the surface. After the spray bar, brush, and wiper blade are used to, respectively, clean, brush, and dry the surface, the engagement mechanism then moves the spray bar, the brush, and the wiper blade to a disengaged position within the housing.

Disclosed are a chassis of an automated guided vehicle and an automated guided vehicle. The chassis includes a front frame (1) and a rear frame (2) that are engaged with each other in a hinged joint manner, so as to allow a relative folding between the rear frame (2) and the front frame (1). The relative folding enables the driving wheels and the driven wheels to touch the ground on a sunken road at the same time to prevent that only the driven wheels (10) touch the ground while the driving wheels (9) slip, and increases the approach angle of the chassis on a convex road to prevent the front end of the chassis from touching any obstacle, which improve the safety of the vehicle. Moreover, the damping device (3) restricts the folding angle of the front frame (1) and the rear frame (2) to prevent that the relative folding angle of the front frame (1) and the rear frame (2) is too large to realize the transport function, and damps the folding angle for reducing vibration.

A military vehicle includes a chassis, a front end accessory drive (FEAD), and circuitry. The chassis includes an engine and an integrated motor generator (IMG). The FEAD includes multiple accessories and an electric motor-generator. The circuitry is configured to operate the military vehicle according to different modes. The circuitry is configured to receive a user input indicating a selected mode of the modes, and operate the chassis and the FEAD of the military vehicle according to the selected mode. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and the tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.

Aspects of the present disclosure relate to an extendable conductor assembly. A conductor of the extendable conductor assembly may be extended (e.g., into a thermal target, such as a preexisting or a newly created feature of a planetary body) and used to thermally couple a rover, vehicle, fixed installation, or other hardware with the thermal target. Thus, the temperature of the hardware may be managed via heat transfer to/from the thermal target. For instance, heat may be transferred from the thermal target to maintain the temperature of the hardware under cold conditions, while excess heat may be transferred to the thermal target under hot conditions. As an example, a rover may form a borehole in the lunar surface, in which a conductor may be extended to facilitate heat transfer between the rover and the Moon accordingly.
