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 device for monitoring an elevator area utilizes a three-dimensional semiconductor sensor for detecting three-dimensional image information. The sensor includes a light source that is mounted so that the elevator area to be monitored is disposed in the illuminated area of the light source, a sensor group that is mounted in such a manner that it receives reflected light, and a processing chip for converting the electrical signals into image information. In addition, the device includes a processing device that is connected with the semiconductor sensor in order to make available three-dimensional image information. The processing device processes the image information in order to obtain state information representing the state of the elevator area to be monitored.

The present invention includes an improved tubular skylight system (10) having a clear acrylic outer dome (20), an aluminum flashing (40), an aluminum light tube (60), an aluminum ceiling plaster ring (80), and a prismatic diffuser (100). The outer dome (20) includes an aluminum ring (24) around the base (22) of the dome (20) which contains a circular channel (32) and holes (34). The aluminum ring (24) allows the outer acrylic dome (20) to be attached directly to the flashing (40) thereby substantially decreasing the risk of crack formation in the acrylic dome (20). Moreover, the surface of the acrylic dome (20) is imprinted to refract, a substantially increased amount of the natural light down into the light tube (60). The lower end (64) of the light tube (60) extends to the inside of the ceiling and sits on the plaster ring (80). The upper end (62) of the light tube (60) is reciprocally received in the flashing (40), but the outer dome (20) attaches directly to the flashing (40).

A scissor lift includes an energy storage device that stores energy as the payload is lowered, and provides further lift to the payload as the payload is raised. This allows the scissors to achieve a support angle of up to 180° between the two arms (down to 0° between the screw drive and the lowest arm of the scissors), making the inventive scissor lifts considerably more compact than prior art lifts. The energy storage device is preferably a helical wire spring, but can alternatively be any suitable spring, piston, or even an elastomeric mass. Side to side movement of the scissors arms can be restricted using a thrust bearing with hardened washers at the inter-arm pivot, and / or a guided connector that transmits motive force to the scissors.

The invention relates to an elevator system with at least one shaft, in which at least two cars can be made to travel along a common traveling path, and also with a shaft information system for determining the positions and speeds of the cars, which is connected to an electrical safety device. In order to develop the elevator system in such a way that a high handling capacity can be achieved with constructionally simple means, while reliably preventing car collisions, it is proposed according to the invention that an emergency stop of at least one car is triggerable independently of the control units by means of the safety device if the distance between a first car and a second car or an end of the traveling path goes below a preselectable critical distance, and that the safety gear of at least one car is triggerable if the distance which this car assumes from the neighboring car or an end of the traveling path goes below a preselected minimum distance, the control units of at least all the cars of one traveling path being connected to one another and altogether forming a group control device.
