An autonomous transport system is disclosed, formed by four main subsystems: a channel subsystem; a vehicle subsystem; a wheel guide subsystem and central control station subsystem. The system is designed for the transportation of people or goods, to be used in tall buildings and in small and large scale urban environments. It comprises unitary vehicles that may move in different directions: horizontal, steeply sloped and also vertical tracks, thanks to novel traction wheel assemblies that roll on carefully designed wheel tracks. The system's cabin maintains the horizontal level / position regardless of the changes of track direction or slanting thanks to pendulum based automatic level control and may rotate up to 180° under normal conditions and even a full 360° turn respect to the wheel assembly in space restricted positions. The cabin is mounted on a cantilever, thereby displacing its center of gravity respect of the wheel guides. Thus, a lever action is established, which presses the wheels against the wheel tracks and therefore enough frictional resistance is obtained so as to avoid wheel slippage on the wheel tracks. The vehicles are moved by non-polluting, electric drives that move and stop them with high energy savings. The vehicle runways are designed taking in account safety features against fire hazards. Several vehicles may be used at the same time and on the same track and may run individually or in groups, conforming a train. The system allows for vehicles to be parked in bypassed positions or else they may be disengaged from the convoy to be used individually.

A folding table and support frame assembly is disclosed. The table comprises two planar portions connected by a hinging member. One of the planar portions is coupled to a support frame such that the folded table can be moved into a stowed position within the support frame assembly. The planar portions comprise a proximal portion or inner member and a distal portion or outer member. The proximal portion and distal portion are connected to one another by the hinging member or middle member. The hinging member enables the rotation of the distal portion into a folded relationship upon the proximal portion. When the two planar portions are folded, they provide a smaller table surface in a half-open or partially extended position. When the two planar portions are opened along the hinging member, the planar portions and the hinging member provide a larger contiguous table in the fully extended position.

An IC chip and a minute antenna for conducting transmission with a weak radio wave are mounted on a male connector. An auxiliary antenna for amplifying the weak radio wave emitted by the minute antenna and transmitting the amplified radio wave is mounted on a female connector. If the male connector is fitted into the female connector normally, then the distance between the minute antenna and the auxiliary antenna becomes 1.0 mm or less, and consequently the weak radio wave transmitted by the minute antenna is amplified by the auxiliary antenna and transmitted to the outside. Unless fitting is conducted normally, then the distance between the minute antenna and the auxiliary antenna becomes longer than 1.0 mm, and consequently the weak radio wave emitted the minute antenna is not amplified and transmitted. By receiving the information stored on the IC chip, the fitting state of the connectors can be checked.

An apparatus for allowing an individual to simply assemble a transparent cylindrical conduit sectioned track system which guides a self propelled toy vehicle through this track system. A self propelled toy vehicle designed to run securely through transparent cylindrical conduit track prohibiting the toy vehicle from falling off of the track, an easy to assemble the transparent cylindrical sections, and an interlocking structure to ensure the fitting of the track sections are secure enough to remain intact for normal use. A portable means for an individual to carry said self-propelled toy vehicle and the various shaped transparent cylindrical track sections.

A self-propelled vehicle (20) for movement within a tubular member (22) includes propulsion mechanisms (28) distributed about a core element (24). Each of the propulsion mechanisms (28) includes a drive belt (28). A first pulley (34), a second pulley (36), and a mid-roller assembly (38) are encompassed by and engage the drive belt (28). The mid-roller assembly (38) is spring-loaded for providing an outwardly-directed force (40) to an underlying portion (42) of the drive belt (28) to press the drive belt (28) against an inner wall (44) of the tubular member (22). A motor arrangement (46), in communication with the propulsion mechanisms (28), actuates one of the first and second pulleys (34, 36) to rotate the drive belt (28) in contact with the inner wall (44) of the tubular member (22) thereby moving the vehicle (20) within the tubular member (22).
