  • Patent number: 12053267
    Abstract: A method and a device for non-contact determination of temporal color and/or intensity variations in objects in a scene. Monoscopic overview images of the scene are detected with first and second overview cameras from two different viewing directions, and calculated to form a stereoscopic overview map. A two-dimensional detail image is detected by a detail camera from a third viewing direction and is projected on the overview map. Measurement surfaces in the scene are selected based on criteria which are predetermined depending on parameters on which conclusions are to be drawn from the color variations and/or intensity variations. Light emitted by the measurement surfaces is detected in a spatially-resolved and wavelength-resolved manner in a continuously-captured series of measurement images in a predetermined spectral range. The measurement surfaces are analyzed in the measurement images with respect to temporal variation of the intensity and/or color of the light, and the results displayed.

    Abstract: An accessory kit is provided for interventional procedures using a magnetic resonance imaging scanner. The accessory kit includes a patient support and an electrical connection adapter. The patient support has a first end proximal and a second end distal to the scanner. The distal end is configured to create a space to accommodate a clinician, such as narrowing of the distal end or at least one cutout on a side of the distal end. The electrical connection adapter interfaces with the scanner and a scanner table. The accessory kit is configured so that when the proximal end is extended into the scanner bore, the distal end extends outside the bore. The narrowed width and/or cutout(s) of the exposed distal end and the extended gap between the scanner and scanner table create space on at least one side of the patient support that a clinician may use to access a patient.

  • Patent number: 11408366
    Abstract: Cylinder arrangement (1) and method for cooling the cylinder arrangement (1) addresses a solution with which the heat transfer from a combustion chamber (6) of an internal combustion engine located in a cylinder liner (2) of the cylinder arrangement (1) into a region (7) surrounding the cylinder liner (2), such as a cylinder block or crankcase, is controlled in a temperature-dependent manner. Arrangement solves said problem by providing a jacket (9), the expansion of which changes depending on temperature, arranged between the cylinder liner (2) and the region (7) surrounding the cylinder liner (2). The method uses the cylinder liner (2) with a jacket (9), expands depending on temperature and surrounds the cylinder liner (2); jacket (9) forms a gap (10) between jacket (9) and region (7) in a first temperature range; jacket (9) forms no gap (10) between jacket (9) and region (7) in a second temperature range.
