Abstract: The invention proposes a drill bit (1) leaving at least one main cutting edge (3, 3?) and at least one center cutting edge (15, 15?), wherein the drill bit (1) comprises a longitudinal axis (13), and wherein the at least one main cutting edge (3, 3?) and the at least one center cutting edge (15, 15?) are each assigned a rake face (7, 7?, 11, 11?). The drill bit (1) is characterized in that the rake face (11, 11?) assigned to the at least one center cutting edge (15, 15?) has at least two part faces (19, 19?; 21, 21?) which—as seen as perpendicular to the longitudinal axis (13) of the drill bit (1)—form an obtuse angle with one another, so that the at least one center cutting edge (15, 15?) comprises at least two part cutting edges (23, 23?; 25, 25?).

Abstract: In an optical angle-measuring device for ascertaining the relative movement between at least one scanning grating and a graduated disk having at least one measuring graduation, the scanning grating is in the form of a linear scanning grating, and the graduated disk includes a first and a second combined radial-circular grating as measuring graduation, and has a mirror. An incident beam of rays is initially split at the scanning grating into two partial beams of rays that then propagate in the direction of the first combined radial-circular grating and are diffracted there, then propagate in the direction of the mirror and are reflected there in the direction of the second combined radial-circular grating, subsequently propagate in the direction of the second combined radial-circular grating and are diffracted there, and then propagate in the direction of the scanning grating, where a superposition of the partial beams of rays results.

Abstract: A cooling device (1) is provided for an electric machine arrangement (M) that has two electric machines (m1, m2). The cooling device (1) has cooling ducts that run helically around the electric machine arrangement (M). Two openings (7, 9) are arranged at one end (11) of the cooling device (1) and permit an entry and exit of a stream of cooling medium. As a result, the cooling device (1) is particular effective with respect to temperature distribution.

Abstract: The present invention relates to an optical position-measuring device for generating a plurality of phase-shifted scanning signals regarding the relative position of a fiber optic scanning head and a reflection measuring standard movable relative thereto in at least one measuring direction. In the fiber optic scanning head, a scanning reticle is disposed before the measuring standard end of an optical fiber. The scanning signals are coded in a wavelength-dependent manner. To this end, a beam incident on the scanning reticle is split into at least two sub-beams which strike the reflection measuring standard and are subsequently recombined to interfere with each other so as to generate the phase-shifted scanning signals. The sub-beams travel different optical path lengths between splitting and recombination.

Abstract: An interferometric distance measurement device that includes a light source that emits a beam of light and a scanning unit. The scanning unit includes a scanning plate having a splitter that splits the beam of light into a measurement beam and a reference beam, wherein the reference beam is propagated solely within the scanning plate before reaching interferential superposition with the measurement beam at a unification site. A reflector is provided, wherein the reflector is embodied such that the measurement beam striking the reflector undergoes retroreflection in a direction regardless of any possible relative tilting of the scanning unit and of the reflector downstream of the unification site. A detector arrangement is provided in which a distance signal relating to a distance between the scanning plate and the reflector is detectable from interference between the measurement beam and the reference beam.

Abstract: A motor vehicle has at least one adjustable air-guiding device on the underbody. The air-guiding device has a cross-sectionally U-shaped duct and is adjustable between a closed position and an open position. The motor vehicle also has a radiator device with a radiator and a radiator shutter with adjustable flaps for controlling the air flow through the radiator. A control device actuates the air-guiding device depending on the position of the radiator shutter so that, irrespective of the position of the flaps of the radiator shutter, an at least approximately identical pitching moment is obtained at the motor vehicle and at the same time the aerodynamic drag is reduced.

Abstract: A double buttress folding top has rear-side tensioning bows with two rearwardly directed U-shaped sections that are connected to each other via a central bow section. The tensioning bows tension the folding top cloth in the region of the buttresses. The folding top cloth is fastened to the tensioning bow. The tensioning bow bears from below against a folding top compartment cover and against edges of lateral body cutouts. The folding top compartment cover therefore has two lateral cutouts which, in the open position of the folding top, are closed by lateral flaps. The tensioning bow is of U-shaped design and, above a rear window, has a bow web to which the rear window is coupled in a hinged or pivotable manner.

Abstract: An ultrasound system for the generation of low-frequency high-power ultrasound includes a resonator for transmitting the ultrasound to a medium. To safely handle the ultrasound system, the ultrasound system has a light source illuminating a workspace of the ultrasound system.

Abstract: A motor vehicle has a cowl (1) with an upper frame part (2) and a closable vehicle roof opening (27) in the region of the upper frame part (2). The cowl (1) has a draft deflector cassette (6) for movably mounting a draft deflector. An interior lining (10) and a frame seal (9) are connected to a side of the upper frame part (2) that faces an interior of the vehicle and a decorative seal (17) interacts with the interior lining (10). The draft deflector cassette (6) is arranged between the frame seal (9) and the decorative seal (17). The draft deflector cassette can be placed, with simple installation, in a visually attractive manner in the region of the upper frame part (2) of the cowl frame.

Abstract: An independent wheel suspension system for a motor vehicle includes an upper strut plane and a lower strut plane. Each of the upper strut plane and lower strut planes includes one longitudinal strut and one transverse strut. Each of the struts has a wheel side end for connection of a wheel holder and a body side end for connection of a body. The wheel-side ends of the longitudinal struts and the wheel-side ends of the transverse struts of the two strut planes are articulatedly connected either directly or indirectly to the wheel holder. The body-side ends of first struts of the two strut planes are articulatedly connected directly to the body. The body-side ends of second struts of the two strut planes are articulatedly connected indirectly to the body via a common coupling element.

Abstract: Systems and methods for customizing behavior of a computing system based on details of interactions with the computing system by a user, such as a direction, intensity, or magnitude of a particular input from a user input device.

Abstract: A method and apparatus to monitor and document movement of bodies along or through selected regions is described for the directional counting of such bodies. The reduction of the consideration to selected regions avoids excessive calculation and allows the use of an inexpensive image acquisition and processor. Methods for the determining the direction of movement are described. A record is created for counting events for recording or downloading to a server for further manipulation.
