The invention relates to an indicating instrument, in particular for a motor vehicle, having a housing with a front frame holding a cover pane, and an elastic spacing element arranged between the cover pane and front frame, and to a method for connecting the cover pane to the front frame. In order to ensure a reliable connection between the cover pane and front frame which is without play, the invention proposes the spacing element be placed in an axial cutout which is arranged in the region of the circumference of the front frame and faces the cover pane, and in which the cover pane can engage. The method consists in that in a first step the spacing element is inserted into the axial cutout in the front frame, and in a second step the cover pane is pressed into the axial cutout against the spacing element.

A plug socket (1) has a plug housing (2) with a baseplate (3). The baseplate (3) has a respective contact surface (9,10) on two opposite sides in order to seat it on a printed circuit board. A contact spring (6) has two support regions (7,8) which are curved in the shape of an arc in opposite directions and which together form the shape of an S lying on its side. The contact spring (6) permits conductor track contact both in the case of surface mounting and plug-in mounting for the plug socket (1).

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.

According to an embodiment of the present invention, a method 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.

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

The invention is illumination gear that has a strap pad slidably mounted on a strap. A battery-operated lamp is mounted on the strap pad. The strap pad with lamp may be adjusted anywhere along the strap, so as to adjust the position of the lamp to a desired height. The illumination gear may be constructed as a harness, as a vest, or as a set of suspenders. Anchor straps may be provided on the vest or the harness, to secure the straps to belt loops on a trouser waistband or to another garment, to prevent the illumination gear from riding up or shifting position.

An example method for generating acoustic waves is disclosed. The example method includes activating at least one driver, transmitting force from the at least one driver to at least one moment arm, and transferring force from the at least one moment arm to at least one plate, thereby causing the at least one plate to vibrate and generate acoustic waves.

A liquid crystal display having a liquid crystal cell (1) has electrical heating formed by an electrically conductive heating layer (3) on a substrate (2). On opposite sides, a clamp (4) forming a busbar in each case reaches over the substrate (2) and bears on the heating layer (3) by a limb (5). For connection to the heating current source, a spring element (7) is arranged between a limb (6) of the clamp (4) and a printed circuit board (8).
