Abstract: A method for operating a braking system for a vehicle. A braking request signal characterizing a braking request is generated by actuation of a positioning assemblage of an actuation circuit, and a target brake pressure required in an active circuit is ascertained based on the braking request signal. An actual brake pressure in the active circuit is established in accordance with the target brake pressure, using a pressure generation device, by moving a displacer piston of the pressure generation device using an electric motor of the pressure generation device. If the braking request signal is constant over a predetermined time period, a wheel brake actuated by the active circuit is hydraulically decoupled from the pressure generation device by closing an isolation valve that is disposed in a hydraulic path between the pressure generation device and the wheel brake, and the electric motor is shut off.

Abstract: Energy distribution structures provide architectural flexibility in various configurations, materials, and scalability, which enables a vast number of applications. An energy distribution structure or array thereof may include a three-dimensional outer component and a three-dimensional inner component within the outer component. The outer component absorbs and redirects initial energy from an applied energy event, and the inner component absorbs and redirects residual energy from the applied energy event. Such an applied energy event may be caused by a ballistic or non-ballistic impact, an instantaneous or prolonged impact such as atmospheric pressure or decompression, explosive overpressure (shockwave), low-velocity contact, and blunt force trauma. Energy distribution structures can increase the strength, resilience or survivability of such events, and reduce the injury or damage to target objects such as people, vehicles, structures, vessels and surfaces by shielding same from such events.
