Abstract: A method and a device for adjusting a seat are provided. The method includes the acts of detecting a pressure exerted by a user on the seat via a pneumatic sensor and/or a hydraulic sensor, and adjusting the seat based on the pressure exerted by the user. The device includes a pneumatic or hydraulic lifting element, a pneumatic or hydraulic pressure sensor connected to the lifting element, and a control unit connected to the pressure sensor. The pressure sensor detects a pressure exerted by a user on the seat, and the control unit controls the first lifting element to adjust the seat based on the pressure exerted by the user.

Abstract: A seat includes a bearing structure and a number of cushions. The cushions cover the entire area of the seat surface and the backrest of the seat. Each cushion is formed of a textile spacer structure held in a fluid-tight casing. The casing has a connection for a hose line. Before a user sits on the seat, the hose line is open to the outside air. Due to the force applied by the seat user, the cushion and spacer structure are compressed, whereby simultaneously air is displaced out of the cushion. The cushions thus experience a contouring according to the body shape of the seat user. After the user sits down, the contouring can be fixed by blocking device the hose line, and thus separating the reduced air volume in the inside of the cushion from the outside air. In this way, the contouring of the seat cushions is maintained when the seat user leaves the seat.

Abstract: A supporting shell for a seat is provided by carrying out in-seat measurements with a plurality of test subjects, wherein the test subjects sit down on a measuring mat placed on a neutral seat frame. The measuring mat has a readily displaceable filling and adapts to the contour of the body of the respective test subject. After the test subject has sat down on the measuring mat and before the test subject leaves the same, the filling inside the measuring mat is fixed in place by applying a negative pressure. The geometric data of the surface contour of the measuring mat are determined and stored for each test subject. The measured surface contours are then superimposed onto one another. This produces an average surface contour which can subsequently be further altered slightly for adaptation to large seat users, and therefore a modified surface contour is created as a basis for the production of the supporting shell of the seat.

Abstract: An ordering scheme is described, for example an ordering and payment scheme for mobile communication devices. The ordering scheme enables an Internet shop or another service provider to issue binding offers to a mobile communication device or the like and to receive an acceptance of the offer from the mobile device. The acceptance is encrypted using a private key of mobile device and the offer may be encrypted using a private key of the service provider. The service provider liaises with a payment broker and a charging system for controlling the transfer of funds from the user to the service provider. An identity management system may be provided to control access to the modules of the ordering scheme.

Abstract: A method and a device for recognizing visual obstructions in image sensor systems are provided. A signal is produced, based on the analysis of the recorded image from the image sensor, which indicates the presence and, optionally, the type, of the visual obstruction on a windshield, for example.

Abstract: The method for the transmission of media data from a multicast service by a first apparatus to a plurality of second apparatuses is suitable for preventing reception of the media data by an unauthorized second apparatus using a security process. A first apparatus is provided which can be used to provide the media data protected by a security process. A third apparatus is provided which can be used to perform the security process with the first apparatus, performance of the security process between the first apparatus and the third apparatus and, on the basis of this, interchange of at least security data between the first apparatus and the third apparatus in order to provide the media data. A second apparatus is selected which can be used to perform at least one reception process for receiving the media data. A first data transmission link is selected which can be used to couple the first apparatus and the second apparatus at least for the purpose of transmitting the media data.

Abstract: A seat having a backrest and a seat cushion includes rows of adjusting elements, respectively, which adjusting elements are arranged above one another, on both sides of the longitudinal center plane of the seat. By alternately applying the adjusting elements mutually arranged in a vertically staggered manner in the two halves of the seat, a rotational movement can be actively applied to a seat user's back and possibly pelvis, which rotational movement corresponds to the rotational movement of the back, and possibly of the pelvis, when walking.

Abstract: The invention relates to a method for online correction of non-linearities in the imaging system during the data acquisition in industrial computer tomography (CT). The above provides a method for the provision of corrected projection data as an improved CT reconstruction, whereby measuring beams (q) are emitted from a radiation source (Q) which pass through the sample (10,11), the intensity of which is recorded by a detector (31).

Abstract: A method and a device for the detection of obstruction in image sensor systems made up of at least two image sensors, which record essentially the same scene. If at least one image feature of the respective images differs unacceptably between the respective images, a signal is generated indicating the obstruction.

Abstract: A method and a processing unit for adjusting the characteristic curve of the exposure sensitivity of at least one pixel of at least one image sensor in a motor vehicle are described. The optimal characteristic curve of the exposure sensitivity is determined from the histogram of the gray values of at least one image as a function of image signals from at least one image sensor. The freely definable characteristic curve of the image sensor having linear segments is chosen so that it agrees at least approximately with the optimal characteristic curve. Along with the size and/or the position of the characteristic curve of the exposure sensitivity, alternatively or in addition the shape of the characteristic curve is adjusted.

Abstract: A method and a device for adjusting at least one parameter of an image sensor of a stereo camera in a motor vehicle. The stereo camera has two image sensors which record essentially the same scene. If an error occurs in one of the image sensors, at least one parameter of this image sensor is adjusted as a function of at least one measured value of the error-free image sensor of the image sensor system. In the preferred exemplary embodiment, the parameter is at least one lighting parameter of the image sensor. In the event of an error of an image sensor of the stereo camera, the at least one lighting parameter is adjusted as a function of at least one measured value of the second image sensor, the measured value being a measure of the lighting of at least one part of the image of the second image sensor.
