A modular electronic damping control system is described and includes a damping component located at a vehicle suspension location. The modular electronic damping control system also includes a control system configured to control the damping component, and determine the type of damping component present. Also, the control system is configured to automatically tune a vehicle's suspension based on the type of damping component present, and automatically monitor the damping component and determine when a change has been made to the damping component so that the control system can then automatically re-tune the vehicle's suspension based on the change to the damping component.

Described in certain example embodiments herein is an electrical controller for a damper body assembly that stores a damping policy and instructions implementing a control method based on the policy. In certain embodiments, the controller receives a sensor output and transmits a signal to alter the contribution to a damping coefficient of the damper from each fluid mass as a function of the sensor output, policy, and control method. Described in several exemplary embodiments herein, are methods of using the electrical controller. Also described in several exemplary embodiments herein are damper body assemblies that can be controlled by the electrical controller, an actuation assembly, and methods of using the same.

A device for damping vibrations in a structure including a first (or inner) element rotatably mounted around a rotational axis and a second (or outer) element rotatably mounted around said rotational axis. A radius (R1) of a circle portion delimitating the first element with respect to the rotational axis, being smaller than a radius (r2) of a circle portion delimitating the second element with respect to the rotational axis.

An electronic modal base valve is disclosed. The electronic modal base valve includes a motive component, a controller communicatively coupled with the motive component, and a control valve coupled with the motive component. The controller is configured to control an operation of the motive component, wherein a movement of the motive component is configured to cause the control valve to adjust a flow rate for a flow path through the electronic modal base valve.

Disclosed is a damping force variable valve assembly capable of improving linearity of a damping force through pressure control by being provided as a poppet type built in a shock absorber and by improving the responsiveness so that a check valve responds and opens quickly by a minimum load.

An adjustable shock assembly is disclosed herein. The adjustable shock assembly includes a damper body having a main chamber with a working fluid therein. An adjustable active valve assembly comprising: a first parallel flow pathway comprising an active valve; and a second parallel flow pathway comprising a firm mode blowoff stack and a firm mode adjuster to adjust a blowoff pressure of the firm mode blowoff stack. A main piston coupled with a piston shaft, and a fluid pathway fluidly coupling the main chamber with the adjustable active valve assembly which is fluidly coupled with a reservoir

A damping force variable shock absorber of the present disclosure is disclosed. The damping force variable shock absorber includes a cylinder having an inner tube and an outer tube filled with a fluid, a housing coupled to a lower end of a piston rod located inside of the inner tube and forming a connection passage therein, a magnet member provided inside the housing, a plunger moving by magnetic force of the magnet member, a first piston valve coupled to the outside of the housing to divide a compression chamber from a rebound chamber, and a second piston valve provided in the housing, wherein the connection passage is provided such that at least a part of the fluid flowing toward the first piston valve is bypassed to the second piston valve side by the opening and closing of the plunger.

Apparatus and methods to reduce unwanted motion in precision instruments are described. An active vibration-isolation system may include a feedback loop that senses motion of an intermediate mass. In noisy environments, where the feedback loop would otherwise fail or provide inadequate isolation, feedforward control can be implemented to sense floor vibrations and reduce motion of the intermediate mass that would otherwise be induced by the floor vibrations. The feedforward control can reduce motion of the intermediate mass to a level that allows the feedback loop to operate satisfactorily.

A vibration damping apparatus configured to damp a vibration of a target member includes a mass body, a base disposed on the target member, a support member disposed on the base and configured to support the mass body, a housing disposed on the base so as to surround the support member, an elastic member disposed so as to form a space in the housing and configured to apply a force to the support member, and a control unit configured to control a pressure of a fluid in the space by supplying the fluid to the space based on a vibration state of the target member.

The present invention relates to a movement-dependent stabilisation support system (100) for stabilising a moving body (200), which comprises a plurality of sensors (110), a plurality of actuators (120) and a control unit (130). The plurality of sensors (110) continuously detects movement parameters of the body (200), on which basis the control unit (130) determines whether there is an instability of the body (200). If it is determined that there is an instability, the control unit (130) selects a stabilisation strategy, according to which the actuators (120) are controlled. When controlled, the actuators (120) attached to the body (200) stiffen and limit the freedom of movement of the body (200), such that a movement in the direction of the imminent unstable state is prevented or suppressed. In this way, the body (200) is supported in its stabilisation and an imminent fall is prevented.
