Abstract: A system for use in maintaining a machine including a cavity is provided. The system includes a pilot apparatus including an insertion end and a steering end opposite the insertion end. The insertion end is positionable within the machine such that the pilot apparatus defines a path through the machine. The system also includes a steering interface configured to steer the insertion end relative to the machine. The system further includes a service apparatus for use in maintaining the machine. The service apparatus is configured to move along the path defined by the pilot apparatus.

Abstract: A structure adaptable moving device includes a flexible ring and one or more driving mechanism. The flexible ring may be adaptable to the changing or non-changing geometries of an environment. Further, the driving mechanism may be configured to the flexible ring and capable of moving the flexible ring in the environment with the changing geometries.

Abstract: Omnidirectional moving device and system are provided. The device includes a chassis member, at least a pair of treading members and a wheel arrangement. Each of the treading members can move in same or opposite directions. Each of the treading members, when moving in same direction, may enable the wheel arrangement to move in the same direction as thereof so as to enable the device to be moved in a second direction (D2); and when adapted to be moved in opposite directions, enables the wheel arrangement to swings at a position thereof to enable the device to be moved in a third direction (D3).

Abstract: The invention relates to a vehicle wheel, comprising a rigid rim and a flexible tire without an air charge, between which resilient spokes, offset at an angle with respect to the radial direction, are situated. The spokes are divided into three or more groups, which are separated axially from one another with an alternating oppositely directed angular offset.

Abstract: A multi-standard connection hub includes a housing (110) having a first surface (111), a second surface (112) spaced apart from the first surface, and a sidewall (113) extending between the first surface and the second surface. The multi-standard connection hub further includes a first connection port (120) at the first surface and a second connection (210) port at the sidewall. The first connection port operates according to a first standard and the second connection port operates according to a second standard.
