The inner vamp is disposed in the outer vamp with the air-exit ports of the inner vamp aligned with the air-exit ports of the outer vamp.

A skateboard and a variable-rate elastomeric steering control spring include a boardside unitary body formed of an exterior first elastomer having a first durometer on the Shore A scale, and an interior second elastomer coupled to the first elastomer and extending at least a length of the exterior first elastomer, the second elastomer having a second durometer on the Shore A scale and a through hole disposed to receive a kingpin of the skate truck; a roadside unitary body formed of an exterior third elastomer having a third durometer on the Shore A scale, and an interior fourth elastomer coupled to the third elastomer and extending at least a length of the exterior third elastomer, the interior fourth elastomer having a fourth durometer on the Shore A scale and a through hole disposed to receive the kingpin; and wherein the first, second, third and fourth elastomers comprise at least two durometers on the Shore A scale between 65A and 100A to enable the boardside unitary body and the roadside unitary body to form the variable-rate elastomeric steering control spring when disposed on the king pin of the skate truck.

The present invention provides a bidirectional energy-transfer system comprising: a thermally and/or electrically conductive concrete, disposed in a structural object; a location of energy supply or demand that is physically isolated from, but in thermodynamic and/or electromagnetic communication with, the thermally and/or electrically conductive concrete; and a means of transferring energy between the structural object and the location of energy supply or demand. The system can be a single node in a neural network. The thermally and/or electrically conductive concrete includes a conductive, shock-absorbing material, such as graphite. Preferred compositions are disclosed for the thermally and/or electrically conductive concrete. The bidirectional energy-transfer system may be present in a solar-energy collection system, a grade beam, an indoor radiant flooring system, a structural wall or ceiling, a bridge, a roadway, a driveway, a parking lot, a commercial aviation runway, a military runway, a grain silo, or pavers, for example.

A resilient platform assembly has a playing deck with horizontally disposed deck panels. Each deck panel has a pair of foot flanges on the bottom of the deck panels. Receiving shoes are attached to the deck panels and configured to receive the foot flanges of the deck panels. A transverse member, perpendicular to the horizontally disposed deck panels, includes a plurality of notches. Each notch is cut in the transverse member in a predetermined spacing pattern. The receiving shoes are installed in the notches and the deck panels are attached to the transverse member through the receiving shoes. Resilient mounts connect the transverse member to a support assembly and allow relative motion between the transverse member and the support assembly. The resilient mounts include a first spring capture assembly attached to the support assembly, a second spring capture assembly attached to the transverse members, and a plurality of springs disposed between the first spring capture assembly and the second spring capture assembly.

An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

A sit ski for an athlete includes a ski, a bucket disposed above the ski and configured to support the athlete, and a suspension disposed between the ski and the bucket. The suspension includes a support frame coupled to the ski, a first rotatable member rotatably coupled to the bucket and to the support frame, a second rotatable member rotatably coupled to the bucket and to the support frame, a shock coupled to the bucket and to the support frame, and a bump stop configured to contact the bucket.

A support assembly for use with snow sports boards includes a base configured to be attached to the snow sports board. A frame has a first portion extending downward and a second portion extending rearward from the first portion. A seat is mounted on the second portion of the frame. A shock absorber extends between the base and the first portion of the frame. During use, the support assembly is configured to support a rider sitting on the seat in a face-forward position with the rider's knees vertically below and forward of the rider's hips.

The present invention discloses an automatic telescopic pole, which comprises a first pole section having an upper end and a lower end; a second pole section telescopically disposed inside the first pole section; a handle disposed on the upper end of the first pole section; an elastic member disposed between the second pole section and the first pole section; a clasp-type telescopic locking device disposed between the second pole section and the first pole section; a driving rod having an upper end and a lower end, and disposed in the clasp-type telescopic locking device along a longitudinal direction of the first pole section; wherein, a button mechanism having a button is disposed on the handle; and, a lock catch is slideably disposed on the handle and in front of the button mechanism.

A support plate for a binding for a gliding board that includes the following: a chassis to be fixed on an upper surface of the gliding board; a damping plate intended to be at least partially interposed between a lower surface of the chassis and the upper surface of the gliding board. The support plate includes a wedge that is less compressible than the damping plate, movable between a hardness configuration, suitable for transmitting a vertical force from the chassis to the upper surface of a gliding board, and inhibiting, at least partially, the compression of the damping plate and between a flexibility configuration, suitable for the force to be retransmitted from the chassis to the upper surface of a gliding board, mainly via the damping plate.
