An error log request is generated by a component of a communication sub-system. The error log request is analyse and compared to entries in one of a plurality of records in a message look-up table. If there is a match between the fields of the error log request and selected entries of a record in the look-up table, a user message request is generated which facilitates the display of a pre-existing...

To prevent gear shift shock in a vehicle power train associated with a turbocharged engine (10) and an automatic transmission (12), an air charging efficiency for engine cylinders is reduced during the gear shifting transient period, e.g., when shifting from first gear range to a higher second gear range. Therefore, when engine output is reduced by means of retardation of ignition timing at the ti...

The equipment includes a component for placing the paper pile on the transport pa...

A device for modifying the thread run at a spooler winding position where a thread runs from a take-off spool to a wind-on spool is located above the take-off spool. The device (10) has a guiding surface (17) in the form of a truncated cone where the contour of greater dia. faces the take-off spool and the cone is incised with a truncated pyramid surface (P) such that its edges (18) penetrate the ...

The method uses a sensor (17), mounted on the conveyor side near the middle of the feeder, for detecting the level of the surface of the auxiliary stack (11). The sensor is connected to the control for extending the supports for the auxiliary stack. A scanner activates or stops the extending movement independently of the sensor's signal. The scanner has modules for detecting the end position of th...

Nonwoven sheet materials, and pressure sensitive adhesive tapes formed from nonwoven sheet materials are provided. The nonwoven sheet materials comprise a randomly interlaced fibrous web of tensilized nonfracturable staple fibers and binder fibers, wherein the fibrous web is pattern embossed, and is interbonded by a chemical bonding agent, physical entanglement, or a combination thereof, and furth...

The method and device is directed to determine the strength based upon monitoring the variations in the intensify of a narrow beam of light transmitted through the sheet as the sheet moves perpendicularly through the beam. Use is made of a sensor (10) consisting of two halves. The source half (12), disposed on one side of the sheet of paper (16), directs a beam of light through the sheet (16) whos...

A thermoplastic polyester series foamed material having a thickness of at least 3 mm and an apparent density of from 0.05 to 0.7 g/cm<3> is diclosed, wherein the crystallinity of the resin in the surface portion within 0.5 mm from the surface of the foamed material is not more than 30% and at least 1% lower than the crystallinity of the resin in the central portion of the foamed material.

A metal detector mounted on the vehicle (V) has one or more aerials (2) located, for example, under the bumpers, and is able to signal the presence of any metals mixed with the paint used for forming the horizontal road markings (1). It is thus possible to control the path which the vehicle follows without the need to use cables embedded in the road surface or megnetisable paints.

A method and apparatus for path planning are presented. Path planning involves propagating cost waves in a configuration space representation of a task space. A space variant metric and budding are used for cost wave propagation. The disclosed method and apparatus are readily adaptable to robots with n degrees of freedom.

The fault testing device (1) has a housing (6) enclosing a test head (5), positioned above the glass or transparent plastics item (2) to be checked and incorporating a light source with a lamp (10) and a number of photosensors (15) for detecting reflected light. An optical lens (7) across the open bottom end of the test head (5) has a central bore (8) for passage of a light conductor (9) coupled t...
