Patent number: 9573700Abstract: Embodiments of the present invention provide a core of individual components having properties such that a system assembled from the components absorbs the kinetic energy of a moving vehicle. The components may be interlocking components. The components may be manufactured of ceramic or polymeric composite or other materials that are strong enough to absorb the vehicle's energy and help stop the vehicle safely by the system's ability to crush or deform upon impact, and not so strong that it causes the vehicle to crumple against the barrier. In one particular embodiment, the components may be modified packing elements that are traditionally used in gas to liquid columns.Type: GrantFiled: July 31, 2014Date of Patent: February 21, 2017Assignee: Engineered Arresting Systems CorporationInventors: Michael T.

Patent number: 9574636Abstract: An electronic semi active control engine mount having a variable air chamber includes a variable air chamber diaphragm that absorbs the exciting force of fluid due to an external force by elastically deforming. An air chamber supports the variable air chamber diaphragm with the atmospheric pressure.

Patent number: 9567192Abstract: An oscillation damper for vibration drivers for suspension from a load-bearing means displays a damping body connected on its opposite end faces to pressure bodies which are variable in their spacing, having a rigid support element which is assigned to the load-bearing means and a rigid support element which is assigned to the vibration driver. The two support elements are connected in an articulated manner by way of flexible ties to each pressure body. The longitudinal axes of the ties form in each case an acute angle with the vertical that decreases as tensile force increases, on account of which high tensile forces can be introduced onto the damping body. Simultaneously with the churning operation of the damping body a pendulum movement of the laterally disposed pressure bodies about the articulations of the ties takes place, on account of which vertical oscillation is largely eliminated.Type: GrantFiled: December 12, 2014Date of Patent: February 14, 2017Assignee: TUNKERS MASCHINENBAU GMBHInventor: Josef-Gerhard Tuenkers
