Shock protection for disk drive embedded in an enclosure
ActiveUS7471509B1Reduce amplitudeExtended durationDigital data processing detailsUndesired vibrations/sounds insulation/absorptionComputer caseHard disc drive
A shock absorbing device for protecting a hard disk drive housing found primarily in portable electronic devices. The shock absorbers include protuberances that emanate from the body of the shock absorber and that extend through apertures provided in the enclosure. Thus, the physical shock is taken up by the body of the shock absorber as well as the protuberances, which increase the compression height of the shock absorber and increase the shock damping characteristics of the shock absorber. This permits decreasing the size of the enclosure, which is often desirable to consumers.

Shock dampening biocompatible valve
A biocompatible valve (200) includes a valve mechanism (250, 230a, 230b), which is mounted and is longitudinally displaceable within a valve mount (210) affixed to a recipient patient. A valve annulus (250) defines an orifice (240) in which a closing mechanism (230a, 230b) is received. Upon a transition from an open position to a closed position of the closing mechanism (230a, 230b), hydraulic shock is introduced into the fluid passing through the valve. The present invention provides a dampening mechanism (280) to mitigate the shock and to dissipate its energy. Various embodiments allow for high order frequency response through relationships between dampening mechanism components.

Guardrail safety system for dissipating energy to decelerate the impacting vehicle
ActiveUS20090272956A1Dissipate impact energyPrevents vehicle instabilityPasturing equipmentRoadway safety arrangementsExtremity PartMechanical engineering
In accordance with a particular embodiment of the present invention, an end treatment of a guardrail safety system includes a terminal portion of a guardrail beam that has a downstream end and an upstream end. The terminal portion of the guardrail beam slopes from a first vertical height appropriate for redirecting an errant vehicle to a second vertical height proximate the surface of the ground at an upstream end of the terminal portion of the guardrail beam. A flattening portion forms a channel through which the terminal portion of the guardrail beam is disposed. A vertical dimension of the channel is greater at a downstream end of the flattening portion than at an upstream end of the flattening portion. An impact plate is connected to the flattening portion for engaging an impacting vehicle at an end of said guardrail beam. During an end-on impact, the impact plate and the flattening portion are advanced longitudinally along the guardrail in a downstream direction by the vehicle. The advancement of the impact plate and flattening portion dissipate energy to decelerate the impacting vehicle. As downstream portions of the guardrail beam are forced into the flattening portion, the guardrail is flattened vertically.

Shock-limiting interface, compact (SLIC)
InactiveUS20070034768A1Dissipate impact energyDisplacement minimizationVehicle seatsStands/trestlesEngineeringUsability
A passive / reactive device protests a Payload from injury or damage due to the shock caused by impact or explosion. When the vehicle or structure mounting the Payload receives a shock pulse, the invention limits the acceleration transmitted from the vehicle or structure to the Payload to an acceptably low, user-adjustable level which is substantially constant or is some other user-adjustable force-displacement function. The invention is capable of doing so even when the peak magnitude of the imposed shock is on the order of thousands of G's, with a rise time to peak on the order of microseconds. The invention can be embodied to operate passively, without any external source of power, sensor system, or CPU, although they can be added to improve certain usability features. The invention also absorbs or dissipates the shock energy in substantially the minimum distance possible without exceeding the user-defined acceleration limit on the Payload. The invention can also react when a shock-producing impact is imminent by repositioning the Payload away from the impact site. The Payload can be a person or persons, or shock-vulnerable equipment. The shock can be created in a number of ways, including an explosion, an impact or collision, the slamming on high-performance boats and some off-road vehicles, earthquake, or even intentional shocks on an amusement thrill ride. The ability of the invention to protect against shock is limited only by its ability to absorb or dissipate the energy of the shock pulse on the Payload. The device can be implemented to protect against shock from any arbitrary direction. The name Shock-Limiting Interface, Compact (SLIC) is coined for this invention.

The terminal support post couples to an upstream end of the terminal portion of the guardrail beam by a resistive, tensile coupling that maintains tension in the terminal portion of the guardrail beam. The resistive, tensile coupling is maintained between the terminal support post and the guardrail beam during an end-on or re-directive impact by a vehicle. However, the resistive, tensile coupling between the terminal support post and the guardrail beam is released during a reverse-direction impact.
