There is provided a headset having a head band, at least one fork for receiving an earpiece and a receiving portion between an end of the head band and one of the forks. The fork is arranged pivotably about a pivot axis. The fork has a first end having a support element. The receiving portion has a slider having at least two receiving positions. The support element engages into one of the at least two receiving positions of the slider and thus limits the maximum deflection of the fork about the pivot axis.

The invention relates to the use of special isocyanate-terminated polyurethane prepolymers in adhesive formulations. Said adhesive formulations can be used in applications in which it is important to prevent or minimize migration of adhesive components when the adhesive layer is in direct or indirect contact with substrates that are sensitive thereto.

An approach is provided for automatic geo-location and social group indexing thereby search geo-locations. A geo-location search learning platform receives a query specifying words, and retrieves context information of a user based upon a criterion. The geo-location search learning platform then assigns to the user a social group identifier identifying a social group based on the context information, retrieves one or more social group indexes based upon the social group identifier, retrieves one or more geo-location indexes based upon the one or more social group indexes, and generates a search result using, in response to the query, the one or more geo-location indexes and the words.
摘要:
An approach is provided for automatic geo-location search learning. A geo-location search learning platform receives a query specifying words, and initiates a point-of-interest search on the query, an address search on the query, and a partial search on some of the words. The geo-location search learning platform then combines results of the point-of-interest search, the address search, and the partial search, determines context information for a user; and sorts the combined results based on the context information thereby recommending the researched results to the user in a priority list as sorted.
摘要:
A safety device for a motor vehicle including a front-end structure, a front bulkhead, which separates the front-end structure from an interior, and a brake apparatus fixed to the front bulkhead and including a brake cylinder, the brake cylinder includes a device for pivoting the brake apparatus, which device, in the event of a vehicle crash, interacts with structural elements disposed in the front-end structure. The safety of a driver present in the motor vehicle may be increased. The device for pivoting the brake apparatus includes a fastening portion and a slide portion with a slide plane.
