Abstract: A wheel assembly to be coupled to a hub of a vehicle may include an inner rim to be coupled to the hub of the vehicle, and an outer rim surrounding the inner rim. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension permitting relative movement between the inner rim and the outer rim. An inboard flange may extend radially outward from an inboard side of the inner rim to define an inboard mechanical stop with the outer rim. An outboard flange may be spaced from the inboard flange and extend radially outward from an outboard side of the inner rim to define an outboard mechanical stop with the outer rim.

Abstract: A single-use sensor interface for coupling a single-use container to a re-usable sensing instrument is provided. The single-use sensor interface includes a polymeric flange couplable to a wall of the single-use container. The polymeric flange has a sidewall and an interface portion configured to receive a deflectable polymeric diaphragm. A deflectable polymeric diaphragm is coupled to the interface portion of the polymeric flange. An instrument coupling portion is sealingly coupled to the polymeric flange. The instrument coupling portion is configured to couple to the re-usable sensing instrument. Another single-use sensor interface for coupling a single-use container to a re-usable sensing instrument includes a polymeric hose adapter and at least one instrument attachment portion. The polymeric hose adapter portion has at least one hose barb configured to retain a hose slid thereover. The hose adapter portion has at least one interface portion that is configured to receive a deflectable polymeric diaphragm.

Abstract: A crawler device 2 includes a crawler unit 5. The crawler unit 5 includes a first support 10 extending along a first rotational axis L1, a pair of crawler structures 20A, 20B mounted on the first support 10 and a pair of ground contacting structures 30A, 30B mounted on the first support 10. The pair of ground contacting structures 30A, 30B are arranged outside of the pair of crawler structures 20A, 20B in a direction in which the pair of crawler structures 20A, 20B are opposed to each other. The crawler unit 5 is supported by second supports 41, 42 such that the crawler unit 5 is rotatable about the first rotational axis L1. An outer periphery of the crawler unit 5 having a circular cylindrical configuration includes first zones Z1 occupied by the pair of crawler structures 20A, 20B and second zones Z2 occupied by the pair of ground contacting structures 30A, 30B alternately arranged in a circumferential direction.

Abstract: A spherical wheel intended to move a vehicle and a vehicle implementing the wheel are provided, the wheel having its rotation motorized by a shaft able to rotate about an axis. The wheel (10) comprises two shells of which the surface follows the spherical surface of the wheel and each of which is bounded by a plane. The shells are each articulated by means of a pivot connection with respect to the shaft, an axis of each of the pivot connections being perpendicular to the plane of the relevant shell. The planes bounding the two shells are secant.

Abstract: Embodiments described herein provide for one or more of: (1) airflow enhancement around a rim using cusps that create virtual surfaces of air with the bike in motion, which also encourage favorable air attachment around the rim; (2) wake reduction by streamlining the airfoil around the rim using trip edges at various points of rim surface transition, which cause a laminar flow to go turbulent for enhancing the streamline effect; (3) a double rim surface, which provides an air slot between the two rim surfaces at a distance that enhances flow attachment and adds energy of air flow around the rim by moving air between areas of high and low pressure; and (4) a tubeless tire rim kit capable of converting conventional rims into tubeless ones and also promoting the sealing of the tire to the rim with minimal air pressure necessary to create the seal.

Abstract: An interlocking, compressible spoke wheel system having a ring of paired spokes. The locking of left and right spokes into pairs provides improved tire displacement under loads. The left and right half wheels formed by sets of left spokes and right spokes. enable a novel mounting system for the wheel rim or tire to attach to the spoke system.

Abstract: A boot with studs built into the sole and heel sections to afford the wearer maximum traction in snow, sleet and ice thereby preventing slippage and possible injury to the wearer during execution of required duties.

Abstract: The present invention relates to a process and device for the automatic regulation of the internal pressure in a pneumatic tire characterized in that the air is forced into the pneumatic chamber of a tire by the centrifugal force generated by the revolution of the wheel, and the pressure inside said pneumatic chamber can thereby be automatically changed in dependence on the speed of rotation of the wheel.
