摘要:
A navigation assistance system for a vehicle enables possible routes from the starting point to a destination to be ascertained with the aid of route network data, a preferred route being specified, and at least one driving recommendation that guides at least one user along the specified route being output, such that no driving recommendations are output that are superfluous for and therefore irritating and/or disturbing to the operator of the vehicle. The number of times or the frequency with which the vehicle has already previously passed at least one location point or junction point of the preferred route is ascertained, and the at least one driving recommendation for this point of the preferred route is suppressed if the ascertained number of times or frequency reaches at least one threshold value.

A self-supporting and self-adhesive molded article is described having a glass transition temperature of less than 10° C. and containing a binder and an aliphatic or cyoaliphatic nonionic surfactant. The binder may contain at least one addition polymer or addition copolymer. The article is redetachable from the material surfaces to which it may be adhered. Thus, the article may be attached, detached and reattached to a wall or cabinet surface and may have paper or other light weight, decorative material attached, detached and reattached to it. The detachment and reattachment process maybe repeated numerous times, particularly with intervening cleaning of the surface of the self-supporting and self-adhesive molded article.

The invention concerns a polyacrylamide-containing composition which is characterized in that it has a molecular weight of between 2,000 and 8,000 g/mol, determined by means of gel permeation chromatography (GPC), and as a 15% aqueous solution still has a Brookfield viscosity of between 100 and 500 mPas at 25° C. The invention further concerns the use of this polyacrylamide-containing composition for the flat bonding of water absorbent and hard surfaces and for equipping plastic surfaces with non-slip protection.

The proposed process for bonding together two substrates with an anhydrous or low-water-content partially crystalline adhesive which is solid at room temperature is characterized in that the adhesive is first activated by internal and/or external friction. The substrates are then joined together with the adhesive between them. When allowed to stand, the structure attains its final strength after a period of between a few seconds to a few days. The friction destroys the crystalline structure and causes the adhesive to become gluey, and re-crystallization gives it its final strength and eliminates the gluey quality. The adhesive is based preferably on polyester or polyurethane and used preferably in the form of a gum stick without impermeable packaging. It is especially suitable for bonding paper, since it does not cause corrugation.

A time base circuit feeds a frequency divider via a current amplifier. A current supply circuit is connected to supply the current amplifier and the frequency divider. The current supply may also be connected to supply the time base circuit; otherwise the time base circuit is responsive to electromagnetic radiation for supplying its own current.

A circuit arrangement CHL technique (current hogging logic) includes individual CHL arrangements each having an emitter, control collectors and an output collector and arranged within an epitaxial layer. The individual CHL arrangements are complementary with respect to one another, and arrangement of one conductivity type being directly integrated in the epitaxial layer and the arrangement which is complementary thereto being integrated in a basin in the epitaxial layer, the basin being doped opposite to the epitaxial layer.

A purchase hub system for an enterprise may enable a purchasing agent to cluster bids from different enterprise buyer systems in the enterprise. The purchase hub system may receive purchasing requests including multiple requirements from the different enterprise buyer systems and suggest potential groupings of the requirements based on, e.g., item categories assigned to the requirements. The purchasing agent may then create a bid opportunity, e.g., a bid invitation or auction, including the clustered bids.

A lateral bipolar transistor has a silicon film which is epitaxially deposited on an electrical insulating substrate. The silicon film is doped with impurities of a first conductivity type such that a portion of the film may be utilized as a base zone. Within the base zone an emitter zone and a collector zone are formed of the second conductivity type. A highly doped zone of the second conductivity type is produced by deep implantation at a position which is contiguous and below the base zone, below the emitter and collector zones, and at a boundary between the silicon film and the electrical insulating substrate. An insulating zone over the film and a conductive layer over the base zone are also provided. The conductive film over the base zone together with the highly doped zone below and contiguous with the base minimize surface recombination and increase device gain.

摘要:
An optoelectronic coupling element having a light-emitting semiconductor device serving as transmitter chip, and a light-receiving semiconductor device serving as a receiver chip, and are firmly connected together through an optic coupling medium (3). This compact coupling element is to have a defined degree of coupling largely independent of the housing and is to be suitable for simple conductor tape mounting. To this end, the coupling medium (3) is an insulating transparent intermediate layer, and the light-emitting semiconductor device (1), the coupling element (3) and the light-receiving semiconductor device (2) are directly laminated one on the other. This optoelectronic coupler is used in particular as an optocoupler for signal transmission.
