  • Patent number: 8820623
    Abstract: A position-measuring device includes a code, including a series of code elements arranged one behind the other in a measuring direction, in which at least two consecutive code elements respectively form a code word containing a position information item, and a scanning device having detector elements for reading the at least two code elements of the code that form a code word, and an evaluation device in which the code word having the current position information may be ascertained from the scanning signals of the detector elements. The scanning device and the code are arranged in a moveable manner relative to each other in the measuring direction. Between adjacent code elements, which have identical properties in the transition region, separating elements having complementary properties are inserted.

  • Patent number: 8822907
    Abstract: An optical position-measuring device includes a scanning bar extending in a first or second direction, and a scale extending in the other direction. The scale is offset by a scanning distance from the scanning bar in a third direction perpendicular to the first and second directions. The device has a light source whose light penetrates the scanning bar at an intersection point of the scanning bar and scale to fall on the scale and arrive back at the scanning bar. At a detector, the light is split by diffraction into different partial beams at optically effective structures of the scanning bar and scale and combined again. A periodic signal is obtained in the detector in response to: a shift between the scanning bar and scale in the first direction due to interference of combined partial beams, and a change in the scanning distance between the scanning bar and scale.

  • Patent number: 8818594
    Abstract: A method is provided for operating a hybrid vehicle (1) having an internal combustion engine (2), an electric machine (4) and having a regenerable filter device that absorbs fuel vapors from a fuel tank of the internal combustion engine. To improve the reproducible operation of a hybrid vehicle with an internal combustion engine and an electric machine, in a purely electric driving mode in which the hybrid vehicle (1) is driven only by the electric machine (4), the regenerable filter device is rinsed by switching on the internal combustion engine (2) with a scavenging strategy that is dependent on the velocity of the hybrid vehicle (1).
