  • Patent number: 11052802
    Abstract: A device (219) includes a housing (301) and a link (320) displaceably arranged in the housing (301) and having an input port (323) configured to receive an input force (269) oriented along a first axis (91), a first output port (321) configured to provide a first output force (261) based on the input force (259, 269), and a second output port (322) configured to provide a second output force (262) based on the input force (259, 269). The link (320) is configured to move the first output port (321) from a start position (291) to a stop position along the first axis (91) by a first distance in response to receiving the input force (269) and to move the second output port (322) from the start position (291) to the stop position (294) along the first axis (91) by a second distance (422) in response to receiving the input force (259, 269). The first distance is smaller than the second distance.

  • Patent number: 10052975
    Abstract: A seat cushion length adjusting device comprises a support, an adjusting member displaceably mounted to the support and configured for attachment to at least a portion of a seat cushion, and an actuator. The actuator is coupled to the support and the adjusting member. The actuator is configured to displace the adjusting member relative to the support. The actuator comprises a power drive, a speed reduction gearing, and a motion conversion mechanism for converting a rotational motion of an output of the speed reduction gearing into a linear displacement between the adjusting member and the support.

  • Publication number: 20120191303
    Abstract: A method for controlling a restraint device for occupants of a vehicle is provided. An environment of the vehicle is captured and a restraint device is triggered depending on object data and vehicle data determined in the environment. An impact probability is determined in stages based on determined object data and/or vehicle data. Depending on the determined strength of impact probability of a respective stage, a restraint device is pre-triggered or triggered, or triggering of restraint device is suppressed and determined triggering information is processed further in a next stage.

  • Publication number: 20060018518
    Abstract: The invention relates to a method for determining a three-dimensional position of passengers of a motor vehicle. The inventive method consists in observing the passengers of the vehicle with the aid of at least two cameras (1, 2, 1?, 2?) which are disposed in such a way that they can operate in non-stereo mode, extracting the appropriate characteristics of the passengers from video data, initialising tracking by means of a head model, verifying said extracted characteristics by pattern recognition and in tracking said verified characteristics by means of said head model. The inventive device based on a store controller which is used for carrying out said method is also disclosed.

  • Patent number: 6577945
    Abstract: A novel method and a suitable device for the cylinder-specific determination of spark failures on a reciprocating engine through a classifying unit based on measurement data that contain information about the number of crankshaft revolutions. For this process, the measurement data are subjected to a pre-processing procedure in the classifying unit and classified through a classification process, wherein within the framework of the pre-processing procedure the data are subjected to a principal axis transformation (HAT). Due to the utilization of this resource-saving method for detecting spark failures on reciprocating engines in accordance with the invention, the processing requirements for once cycle are less than 5 Kflops, despite a measurement vector v length of 240. Due to the fact that the invented device requires only a single measurement data recorder, e.g.

  • Publication number: 20030098909
    Abstract: The invention concerns a device for the optical monitoring of the internal space of a vehicle, wherein the vehicle internal space is monitored by at least one panorama camera (2; 4), of which images are supplied in curvilinear coordinates, wherein the images obtained from the panorama camera (2; 4) are transformed to cylindrical or planar coordinates (6) and wherein the transformed images are subjected to an electronic image evaluation (8). The invention makes it possible with one single camera to carry out various monitoring functions both in the internal spaces as well as the external space of the vehicle.
