A holding device for medical instruments, having a bracket on which at least one medical instrument can be affixed, at least one joint to position the bracket and a weight-relieving system to compensate the bracket load. The holding device is of compact and light structure and for cleaning purposes is completely autoclavable together with the bracket. The weight-relieving system is configured as a resetting element that is coupled with the bracket and is made of a material that essentially includes a plateau stress.

A method and apparatus are disclosed for cooling damping fluid in a vehicle suspension damper unit. A damping unit includes a piston mounted in a fluid cylinder. A bypass fluid circuit having an integrated cooling assembly disposed therein is fluidly coupled to the fluid cylinder at axial locations that, at least at one point in the piston stroke, are located on opposite sides of the piston. The cooling assembly may include a cylinder having cooling fins thermally coupled to an exterior surface of the cylinder and made of a thermally conductive material. The bypass channel may include a check valve that permits fluid flow in only one direction through the bypass channel. The check valve may be remotely operated, either manually or automatically by an electronic controller. A vehicle suspension system may implement one or more damper units throughout the vehicle, controlled separately or collectively, automatically or manually.

A dampening bearing support member having a plurality of bearings disposed between an object and a base with rheological fluid disposed around the bearings and structure to retain the rheological fluid in such position, with the rheological fluid being under the control of the user at times when it is desired to stiffen the rheological fluid and limit or prevent movement of the bearings and the object in relation to the base.

By providing an elongated profile which incorporates a plurality of indentations formed therein, a load bearing / cushioning / supporting element is realized. By employing this construction, the element accommodates large strain under force, and shows good resiliency and repeated recovery. The element can be produced from a continuous extrusion process with immediate manipulation to re-shape the extrusion profile, or secondary thermal forming process which follows the extrusion process, or blow molding process, or injection molding process.

Apparatus and method are provided for decreasing frictional effects in stacks of Belleville springs and limiting deflection of the springs. In one embodiment, carriers for springs overlap and minimize the effects of lateral forces that are developed as springs in a stack are loaded. Carriers may be used on mandrel guides, in cylindrical guides or without a guide. In other embodiments, maximum load and defection of springs may be provided by the spring carriers.

A damping brace having an axial force member for providing bearing forces against tensile or compressive forces, a constraining member for constraining the axial force member, and a stiffening part for supplementing the stiffness of the axial force member. An adhesion preventive coating is provided for preventing adhesion between the constraining member and the stiffening part. A length of the stiffening part extending along the axial direction and the gap between the stiffening part and the constraining member are defined in such a way as to prevent an end of the axial force member from rotating in the axial direction beyond a specific angle when the compressive force is applied to the force member.

The invention discloses a six-degree-of-freedom micro vibration abatement platform. The six-degree-of-freedom micro vibration abatement platform comprises a foundation platform, a load platform, six sets of totally identical single-degree-of-freedom active / passive composite vibration insulating devices, and a controller; and the upper and lower two ends of each set of single-degree-of-freedom active / passive composite vibration insulating devices are respectively connected with the foundation platform and the load platform. A control method comprises logic shaft signal calculation, logic shaft control signal calculation, physical shaft real-time control signal calculation and transfer steps. The six-degree-of-freedom micro vibration abatement platform is simple in structure and adjustable in rigidity, can inhibit and isolate six-degree-of-freedom micro vibration in translation and rotation directions of axles X, Y and Z, can be suitable for different places, can effectively attenuate micro vibration on different frequency bands, provides reliable guarantee to precise machining and measuring equipment under micro vibration environments, solves the problems of complex structure and complex control mode in a traditional active / passive composite vibration insulating mechanism, and realizes multi-degree-of-freedom vibration inhibition.

A collision energy-absorbing device includes a body member connected between the frame assembly of a motor vehicle and a bumper beam. The body member collapses as the bumper beam and the frame assembly are moved relatively toward one another during a vehicle collision. The body member has a first telescoping portion and a second telescoping portion that are connected by a connecting portion. The telescoping portions have different cross-sectional dimensions to enable the telescoping portions to move one within the other into collapsing telescoping relation as the body member collapses with the connecting portion being deformed and received between the telescoping portions. One or more protrusions extending from one of the telescoping portions interfere with relative movement of the other of the telescoping portions to retard movement of the telescoping portions into telescoping relation.
