摘要:
The invention relates to a radio transmission/radio reception device and to a method for communication within a, in particular wireless, motor vehicle communication system interacting in ad-hoc fashion which are configured such that the radio transmission/radio reception device emits a piece of information about the scope of envisaged reports, at least one further radio transmission/radio reception device receives the information, and the further radio transmission/radio reception device takes the received information as a basis for stipulating a frequency for the emission of chronologically successive reports.

A mechanism is provided for reorganizing a source index tree of a database table resulting in a target index tree of the database table is provided. A backup process reads source leaf pages of the source index tree in a logical order defined by a sequence of index keys. The logical order can be different from a physical order of the source leaf pages defined by a sequence of respective storage locations. The backup process constructs target leaf pages of the target index tree maintaining the logical order. A restore process constructs target non-leaf pages of the target index tree based on the distribution of the index keys among the constructed leaf pages and stores the target leaf and non-leaf pages.
摘要:
A method and system for preventing redundant indexes in a database management system (DBMS). A received create-index command specifies a new index to be created for retrieving data from a table created by the DBMS and a redundancy check to be performed for the new index in conjunction with an action parameter in the create-index command. If the action parameter includes a REPORT value, each redundant index is stored and/or displayed and the new index is created. If the action parameter includes a PREVENT value and an existing index is redundant in view of the new index and the new index is not redundant in view of the existing index, the existing index is deleted and the new index is created. If the action parameter includes a PREVENT value and the new index is redundant in view of an existing index, the new index is not created.

Apparatus for releasably coupling a drawer to a rail, which can be pulled out in a longitudinal direction, of a drawer pull-out guide, having a holding part which interacts with a mating holding part in the coupled state in order to establish the releasable connection, wherein at least that region of the holding part which comes into contact with the mating holding part is made flexible, preferably by attaching a flexible piece of material, so that any longitudinal play of the drawer which may occur in relation to the rail can be compensated.

The invention relates to a pull-out guide for drawers comprising a first and at least one second rail, at least one carriage with load-transmitting roller bodies being arranged between said two rails. The carriage can be coupled to the second rail, particularly when deviating from the differential course between the two rails, characterized in that a rolling or sliding body is mounted in a freely movable manner on or in the carriage, through which the carriage can be coupled to a coupling part on the second rail, and that a recess is provided in the first rail into which the rolling or sliding body can be moved during opening of the drawer, wherein the coupling part can de decoupled from the rolling or sliding body and passes along the carriage.

A method for generating acoustic waves, the method having the steps of: extending a tine from a support structure so that a proximal end of the tine is attached to the support structure and a distal end of the tine is uninhibited; positioning an oscillator so as to be supported by the support structure and to mechanically communicate with the tine; and oscillating the tine with the oscillator.

A motion control device (1) for guide rails of drawers comprising a carcass rail (2), a drawer rail (4) and a central rail (3) arranged between those two rails (2, 4) at both sides of the drawer, wherein the load of the drawer is transmitted by rollers (6, 6′, 15, 15′) which are preferably arranged in carriages, characterised in that the motion control device (1) has a releasable coupling device (9) between at least one roller (6, 6′) and the carcass rail (2).

A combination instrument (1) has a front frame (2) having a cover (7) which has a plurality of recesses (4, 5) for indicating instruments or other displays. The cover (7) is covered with a decorative element which is formed as a molding (3) and around which a section (8), which is designed as an undercut, of the front frame (2) grips. To this end, the front frame (2) is produced in an injection molding process, the molding (3) being placed into the injection mold. The connection of the molding (3) to the front frame (2) can take place such that it is invisible to someone looking at it, thereby enabling an attractive, visual appearance and simultaneously reliable way of fixing it to be achieved.

A support construction is provided for fixing at least one furniture drive for a movable furniture part in a furniture body. The support construction includes two lateral holding portions and a transverse bearer extending between the holding portions. The holding portions have fixing means for preferably releasably fixing the holding portions to a respective pull-out-guide assembly.
