  • Patent number: 9920775
    Abstract: The present invention is a distributed piston elastomeric accumulator which stores energy when its elastomeric member stretches from its original length in response to the flow of a pressurized fluid. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid as its elastomeric member returns to its original length and moves the piston to its initial position. At least one part of the novelty of the invention is that the accumulator is not subject to radial strain gradients and the accumulator allows for precise pressure and linear position measurements. Accordingly, the invention allows for optimization of the energy strain storage capacity of a given elastomer.

  • Publication number: 20170238700
    Abstract: Collapsible fabric pods may include a plurality of posts attached to a base and a fabric bin array attached to the plurality of posts, wherein the plurality of posts are displaceable between an upright position and collapsed position. When the plurality of posts are in the upright position, the plurality of posts support the fabric bin array above the base, and when the plurality of posts are in the collapsed position, the plurality of posts are decoupled or displaced and the fabric bin array is in a compressed position on top of the base.

  • Publication number: 20170237314
    Abstract: An electric motor assembly includes a rotor, a stator, and a gear assembly. The gear assembly includes a drive gear, a ring gear, and an intermediate gear disposed between and engaging each of the drive gear and the ring gear. The gear assembly further includes a carrier supporting the intermediate gear and being fixed relative to the stator so as to be stationary relative thereto. The ring gear is rotatable relative to the carrier and the stator.
