The invention relates to a machine for milling traffic areas. The machine has a vertically adjustable chassis which carries a steerable traveling mechanism and a drive unit for moving the machine and for driving a milling mechanism coupled to the drive unit. A laser scanner is attached to at least on one side of the chassis. With the laser scanner, the height relative to the surface of a traffic area to be milled can be measured and the chassis can be set vertically in accordance with the measur...

A radiant heater is provided, which is subdivided into three concentric areas and which can be mounted under a glass ceramic cooking area. It has a rod controller and the two innermost heating areas are jointly protected against excess temperatures by means of the rod controller. The outermost heating area has a low surface power of 2.5 W/cm.sup.2, for example, and consequently does not have to be monitored by the rod regulator with regards to the danger of an excess temperature for a glass cera...

According to the procedure for the definition of the topology of a cellular radiotelephony network consisting of several clusters to be defined, of stations for the administration of respective cells with shared borders, the stations of each cluster, each linked to a controller, connected to other controllers intended to administer the mobility of terminals, the motion of terminals is modeled using a motion algorithm that distinctly corresponds to the law of random motion for particles of ideal ...

An activation device for supplying an electrical signal to a lamp in response to an outside force comprising a hollow tube, a ball placed within the hollow tube, the ball of a diameter less than the diameter of said hollow tube, a piezo device including a piezo bender coupled to an end of the hollow tube, wherein the outside force produces movement of the ball such that the ball traverses the tube to strike the piezo bender thereby producing an electrical signal; and means for using said electri...

An organizer for a vehicle cargo area has a telescoping cross member that is connected to a pair of end supports and can be adjusted to continuously variable lengths for fitting into different sized cargo areas. An optional accessory holder can be attached to the organizer and hold safety items such as battery jumper cables, flares, and/or first aid kits. Reflectors are provided on the organizer to improve its visibility, especially when used to warn approaching motorists of a disabled vehicle. ...

A rest area is provided in the crown of an aircraft, above the ceiling of the main passenger cabin. The rest area includes a longitudinally extending aisle having a floor lowered into the overhead bin structure of the passenger cabin, and raised beds accessible from the aisle. The beds can extend longitudinally at opposite sides of the aisle, or transversely of the aircraft with end access from the aisle. The rest area can incorporate a lounge consisting of a couch, recliners, and/or storage uni...

A method for monitoring large surface areas. A thermal camera and an electromagnetic radar are rotated about a vertical axis to scan the area. The area is divided into sector-like surface elements. Monitoring criteria are established for each of the surface elements. Movements in the surface area being monitored are detected by the radar. The thermal camera is used to detect objects different, in temperature, from their surroundings. Detected objects are located in a surface element and identifi...

A drive sprocket for use with a belt module having a lower surface, and a pocket formed in the lower surface having a drive surface and a recessed surface includes a base having an outer periphery rotatable about an axis, and a plurality of teeth extending radially from the outer periphery. Relief areas formed between the teeth collect particles falling from the belt. At least one tooth includes a drive surface for engaging the module drive surface, and a top. Tooth sides extend from the top and...

A gas burner for cooking areas includes a lower part and an upper part. The upper part has gas repulsion ducts with gas outlet openings for gas flames. The upper part is rotatably mounted on the lower part by a compressed-air bearing configured to apply a compressed-air cushion to pneumatically lift the upper part off the lower part for allowing contactless turning of the upper part in relation to the lower part about an axis of rotation. The gas repulsion ducts are formed to drive the upper par...

A manufactured multi-layered silicon wafer with a buried insulating layer and buried areas with different parameters is formed by bonding together a first wafer and a second wafer. Before the bonding, areas with modified layer parameters, which will be buried by bonding with the second wafer, are created on the surface of the first wafer, which also has an insulating intermediate layer. A further insulating layer is then applied, and the surface of the first wafer is bonded to the surface of the...
