An engine mount device includes a housing, a carrier within a cavity in the housing, and a flexure flexibly connecting the carrier to the housing, with a pin disposed in a hole in the carrier to support an engine. A method of providing isolation in the engine mount device includes transmitting a force from the pin into the carrier; mechanically isolating the carrier from the housing via the flexure; and providing, via the flexure, a higher stiffness in one or more radial directions of the hole compared to a stiffness provided in an axial direction of the hole.

A device for an extensible and compressible friction-based damper which selectively resists stroking in a first direction while freely sliding in the opposite direction. Resistance is proportional to an adjustable and pre-settable value, which provides and adjustable static-hold capability. Sliding resistance being substantially independent of the relative position, velocity, acceleration or jerk (d3x/dt3) imposed upon it. Dampers according to the present disclosure can eliminate resonance amplification when combined with other conventional suspension components. The damper may be used in applications such as isolation mounts. Also disclosed is a method for a high-performance isolation mount to protect a Payload (persons or equipment) from mechanical shock and vibration, incorporating one or more dampers according to the present disclosure together with one or more elastic elements. A device made according to the present disclosure is dubbed a Smooth Transient Excursion Non-Resonant (STEN-R) Damper.

An earthquake force limiter and energy dissipater for racks or buildings. The device allowing stable yielding action of a flexure plate to enable control structures or standard structural frames to form a stable cycling high displacement elasto-plastic mechanism in resistive response to a seismic ground motion input. The stable flexural yielding of the plates limits the magnitude of forces developed within the control structure of which the plates are part of; or within a standard structural frame found in racking structures or general building structures, which the plate is typically directly supportive of. The design reduces prying action or tensile or compressive membrane forces developing in a plate of the device; so that the plate can maintain a stable constant resistive force while yielding to high transverse displacements.
