In some embodiments, the present systems include, consist of, or consist essentially of a roadarm having a first end, a second end, and an opening near the first end; where the second end is configured for attachment to a passive spring (e.g., an air spring, a coil spring, a compressible fluid spring, or a leaf spring), and the opening is configured for interchangeable use with any of: (a) a passive suspension system damping element, (b) a semi-active suspension system damping element, and (c) an active suspension system actuator. Other systems are included, such as those with common control systems for the active and semi-active suspension systems. Methods relating to such systems.

Suspension-related systems and methods

The method and apparatus of the present invention provide constant force suspension and near constant force Suspension and associated control algorithms, all of which may be utilized in vehicle suspension systems. By using the apparatus of the present invention, a vehicle may be isolated from the motion of a wheel as it follows rough terrain, thereby improving ride quality.

Constant force suspension, near constant force suspension, and

An electromagnetic projectile launcher or railgun capable of withstanding hundreds or thousands of shots. The railgun features a current management system having guard plates which act to reduce peak rail current densities while also maximizing projectile velocity. Guard plates can be used in either square or round bore designs and can be powered by either a single or separate power supply from that of the rails.
