Methods and apparatus for regulating the function of a suspension system are disclosed herein. Suspension characteristics often contribute to the efficiency of a suspended system. Depending on the desired operating parameters of the suspended system, it may be desirable to alter the functional characteristics of the suspension from time to time in order to maintain or increase efficiency. The suspension hereof may be selectively locked into a substantially rigid configuration, and the damping fluid may be phase separated and/or cooled to increase damping rate during use (or offset rate degradation). The suspension hereof may generate power usable to achieve any or all of the foregoing or to be stored for use elsewhere in the suspended system or beyond.

A method for coupling a number of utilities between a first system and a second system is provided. A first interface that couples the number of utilities between the first system and the second system is created between the first system and a utilities unit. The first interface is activated. A second interface between the second system and the utilities unit is deactivated, while the first interface remains activated.

Provided is a damper with which the energy efficiency for attenuating input vibration corresponding to the unsprung resonance frequency and the sprung resonance frequency can be improved. Also provided is a method for manufacturing this damper. In this damper the electrical resonance frequency, as specified by the inductance of an electromagnetic motor and the capacitance of a capacitor, is set within 20% of the unsprung resonance frequency, thereby enabling the input vibration corresponding to the sprung resonance frequency as well as the input vibration corresponding to the unsprung resonance frequency to be reduced.

An apparatus for accessing an interior of a fuselage assembly. A tower having a number of platform levels may be driven into a selected tower position within an assembly area. The interior of the fuselage assembly may be accessed using the number of platform levels.

A regenerative shock absorber that includes a housing and a piston that moves at least partially through the housing when the shock is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor, in turn, drives an electric generator that produced electric energy. The electric energy may be provided to a vehicle, among other things. The regenerative shock absorber may also provide ride performance that comparable to or exceeds that of conventional shock absorbers.

A device that converts linear motion into electricity using the exiting movement of a system or equipment such as electric vehicles, motorcycle, or similar equipment. This device can replace the shock absorber of an existing electric vehicle generating electricity that can be used to charge the batteries extending the range of the vehicle. The device is simple an efficient and it comprises of a screw, a plurality of gears used to amplify rotation, a rotor that has magnets, and a stator that allows the coils to produce electricity.

A self-adjusting suspension system according to the present disclosure may be incorporated into an electric vehicle design by way of an integrated air supply system. The integrated air supply system measures and adjusts amounts of pressurized air within pneumatic components of the electric vehicle to provide a predetermined desired amount of suspension. The integrated air supply system also may be used to provide air to pneumatic tires of the vehicle, without the need for an external pump.

A damper assembly to harvest energy from road deflections including a housing with a first shell, a second shell affixed to the first shell and to a vehicle body, a generator assembly with a first generator nested in the first shell, and a second generator nested in the second shell, a ball screw crossing the housing and with a first terminal portion that protrudes from the first shell and affixed to a wheel assembly of the vehicle, a second terminal portion that protrudes from the second shell, and a central portion extending between the first terminal portion and the second terminal portion, wherein the central portion actuates the first generator to provide a first electrical current when the wheel assembly is displaced in a first direction and the second generator to provide a second electrical current when the wheel assembly is displaced in a second direction.

A method and apparatus for accessing an interior of a fuselage assembly. A tower having a number of platform levels may be driven into a selected tower position within an assembly area. The interior of the fuselage assembly may be accessed using the number of platform levels.

A method and apparatus for building a fuselage assembly for an aircraft. A number of fixtures may be drive across a floor to an assembly area to form an assembly fixture. The fuselage assembly may be built on the assembly fixture.
