The present invention relates to a method for sensing information about the position and/or movements of the body of a living being or a part of the body inside the body, in particular for use in a motor vehicle. The method includes the steps: Send (18) an electromagnetic signal (15) that includes, according to the invention, frequencies in the radar range, to a predetermined area of the body of a living being, Receive (20) an electromagnetic signal (22) reflected from the area of the body, Evaluate (30) the captured receive signal (22) with regard for the difference in delay time and/or frequency relative to the transmit signal (15) to determine the information. With the method according to the present invention, the breathing and heart rate and the position of the body of a driver of a motor vehicle can be monitored in contactless fashion during the drive.

The invention relates to an apparatus for making a thin hot strip (1) by roll casting in a continuous process, comprising a casting machine (2) in which first a thin slab (3) is cast, at least one rolling train (4, 5) downstream of the casting machine (2) and in which the thin slab (3) is rolled using the primary heat of the casting process, and a plurality of finish-rolling stands (7) that, relative to a travel direction (F) of the strip (1), are arranged in a downstream region (6) and that can roll the strip (1) with work rolls (8) to a final thickness. To improve the manufacture of a thin hot strip in the continuous process, the invention provides that the work rolls (8) of the finish-rolling stands (7) have a low-wear roll surface. Furthermore, the invention relates to a method of making a thin hot strip (1) by roll casting in a continuous process.
