Structure of the front of a vehicle body
InactiveUS6540275B1Pedestrian/occupant safety arrangementRailway wheel guards/bumpersEnergy absorptionEngineering
The invention provides a structure of a front part of a vehicle body that is simple and free from the risk of maloperation. In the event of a collision between the vehicle and a pedestrian, a projecting part sweeps the pedestrian by parts of his or her legs lower than the knees in the event of a collision between the vehicle and the pedestrian, causing the pedestrian to be thrown over toward the vehicle, and after an energy-absorbing member has absorbed impact energy exerted on the legs, the pedestrian is caused to drop onto the top of a hood and protected from secondary damage. In one specific example, a structure of a front part of a vehicle body in which a bumper (9) is provided at a lower front position of a hood (1) of the vehicle comprises a lateral supporting member (7) provided in the front part of the vehicle body and extending in the direction of vehicle width, an energy-absorbing member (8) provided ahead of the lateral supporting member (7), and a projecting part (12) provided at a lower part of the bumper 9 in such a manner that a forward end of the projecting part (12) juts out more frontward than the lateral supporting member (7).

Method and apparatus for an adaptive impact absorbing helmet system
A method and apparatus for construction of a protective head covering (helmet) to be worn by individuals engaged in activity that may, without the apparatus, cause concussive brain injury. The helmet, which is comparable in weight and envelope to conventional helmets, can be constructed from commercially available materials. The design features a dual shell concept where outer shell deflection under load triggers the primary attenuation mechanism. A second more rigid inner shell defines a space where one or more compartmentalized sealed elastomer energy absorbing cells are located. These cells contain either a gas or liquid agent designed to adaptively convert potentially injurious normal impact force energy to energy that is channeled between the shells and therefore harmless to the wearer. A portion of this converted energy will be stored and then utilized to automatically re-set the apparatus for the next impact event.

Intraocular implant devices
A deformable intracapsular implant device for shaping an enucleated lens capsule sac for use in cataract procedures and refractive lensectomy procedures. In one embodiment, the intraocular implant devices rely on thin film shape memory alloys and combine with the post-phaco capsular sac to provide a biomimetic complex that can mimic the energy-absorbing and energy-releasing characteristics of a young accommodative lens capsule. In another embodiment, the capsular shaping body is combined with an adaptive optic. The peripheral capsular shaping body carries at least one fluid-filled interior chamber that communicates with a space in a adaptive optic portion that has a deformable lens surface. The flexing of the peripheral shaping body in response to zonular tensioning and de-tensioning provides an inventive adaptive optics mechanism wherein fluid media flows between the respective chambers “adapts” the optic to increase and decrease the power thereof. In one embodiment, the capsular shaping body carries a posterior negative power adaptive optic that can be altered in power during accommodation to cooperate with an independent drop-in exchangeable intraocular lens.

A bumper construction for a vehicle includes a swept tubular bumper beam having a pair of spaced-apart brackets and a pair of towers configured to attach to the brackets and support the bumper beam on a vehicle. The towers each include a platform configured for attachment to one of the brackets, and further include an elongated portion configured for connection to the vehicle. A swivel connection connects the tower to the bumper beam. The connection includes a protruding section on one of the bracket and the tower, and a socket receiving the protruding section on the other of the bracket and the tower. The protruding section and the socket are configured to draw the tower toward an impacting force during a catastrophic impact, such that the tower is more likely to crush with a high-energy absorbing, accordion-like collapse (as opposed to a low-energy absorbing parallelogram-like collapse).

Catheters having selectively insertable or selectively activatable and releasable stiffening mechanisms are provided. In general, the catheter is inserted, navigated and withdrawn from a subject in a relaxed, flexible condition and stiffening mechanisms are deployed to prevent the catheter from shifting during placement or operation of an accessory device or tool through the catheter. Stiffening members(s) may be inserted into and removed from one or more longitudinal channel(s) provided in proximity to the catheter wall and generally coaxial with the primary catheter lumen to change the stiffness properties of the catheter. The properties, configuration and size of the stiffening members and channels may be varied to vary the stiffness properties of the catheter and stiffening members may be constructed from materials having shape change properties or materials that change conformation or stiffness with application of heat, current or electrical field. Stiffening mechanisms may also employ energy absorbing and viscoelastic polymer materials having variable stiffness properties depending on ambient conditions.

Wave energy conversion device for desalination, ETC
InactiveUS7023104B2Improve efficiencyEasy to operateWind motor controlGeneral water supply conservationWater qualityEngineering
An impulse-type “wave motor” employs a seabed-mounted or supported structure mounting a wave energy absorbing panel on a hinged lever arm for reciprocation motion to obtain optimal absorption of wave energy from wave motion in the sea. For deepwater wavelengths of L, the panel is optimally positioned in a region within L / 2 depth from the sea surface. The panel motion is coupled by a connecting rod to a fluid pump which generates a high-pressure fluid output that may be used to drive a reverse osmosis desalination unit or to produce other useful work. Seawater or brackish water may be desalinated through reverse osmosis membranes to produce water quality for consumption, agricultural, or other uses. The submerged operating environment of the device in a region of one-half the design wavelength provides the maximum available energy flux and forced oscillations. The pump may be of the positive-displacement piston type, plunger type, or multi-staging driver type, or a variable volume pump.

The method comprises positioning a biomaterial at the site of the section and bonding the biomaterial to the site or to the tissue surrounding the site. The bonding is effected by contacting the biomaterial and the site, or tissue surrounding the site, at the point at which said bonding is to be effected, with an energy absorbing agent. The agent is then exposed to an amount of energy absorbable by the agent sufficient to bond the biomaterial to the site or to the tissue surrounding the site.
