Abstract: A stretchable belt (1) provided for medical purposes for use on the body of a patient has at least one sensor (8) for detecting at least one parameter of the patient's body. An adaptation to different body sizes and motions of the patient is provided without separate length adjusting members being necessary or without the need to stock different belt sizes. Furthermore, the belt is able to be manufactured at a low cost and makes possible simple and reliable handling, even for patients. The belt material (1) has at least one material area (2) with a lower spring rate in the longitudinal extension than at least one material area (3) with a higher spring rate of the belt (1).

Abstract: In an exhaust gas turbocharger for an internal combustion engine, with a turbine wheel arranged in the exhaust gas stream of the engine and including a heat-resistant light metal alloy, with a compressor wheel arranged in the intake air stream of the engine, with a shaft including steel, the compressor wheel being seated on the shaft and the turbine wheel being connected to the shaft by welding, and with a mounting for the shaft, a hub adapted to the shaft diameter is formed on the turbine wheel, the connection point between the hub of the turbine wheel and the shaft being arranged in the vicinity of the mounting.

Abstract: A device (1) and a corresponding method are provided for determining and/or monitoring the respiration rate based on measurement with more than one sensor (5, 7, 9, 13, 15). The device may be part of a monitor for determining and/or monitoring the respiration rate. The second and/or additional sensors are different form the first sensor and have a different manor of operation from the first sensor.
