An engine mount apparatus may include a mount housing which has an internal space; a partition device which partitions the internal space into an upper space and a lower space; a nozzle plate which is provided in the upper space and allows a fluid to selectively pass through the nozzle plate; an upper diaphragm which is fastened to an upper surface of the nozzle plate and defines an upper liquid chamber; a core which penetrates the partition device, and has an upper portion disposed in the upper space, and a lower portion disposed in the lower space; a lower diaphragm which extends from the upper portion of the core to a lower surface of the nozzle plate, and defines a lower liquid chamber; and a rubber member which is provided in the upper space, and connects the upper portion of the core and the partition device.

The invention relates to an article (1) having a main body composed of a polymeric material having elastic properties, in particular an air spring bellows (1), a metal-rubber element or a vibration damper. In order to improve its fire-retardant and/or flame-retardant properties, the article has been provided partially or completely with a flock (9).

Vibration isolator systems have continuous frameworks wherein the frameworks are formed for specific applications. The continuous frameworks have linkages and voids formed and located such that frequency, direction and magnitude of vibrations are accounted for. The linkages and voids configuration provides elasticity and compliance such that a wide selection of materials is available for effective use. The continuous framework can be configured to include active elements such as a control circuit. The active elements may further include electric and magnetic field generators. Further, elastic and insulating materials can be easily added to the framework.

Thermally conductive shock absorbers for electronic devices are disclosed. An electronic device includes a housing and a hardware component positioned inside the housing. A thermally conductive shock absorber is located between an inner surface of the housing and the hardware component. The thermally conductive shock absorber including an impact absorbing material and a thermal conductive material being in contact with at least a portion of the impact absorbing material.
