摘要： A temperature probe in which mechanical oscillatory excitation that can lead to fracture of the connecting lines is prevented and the response time of the temperature probe to temperature changes is shortened. According to the invention, a resistance element is disposed in a flow window of the temperature probe which is formed by a protective bracket and which projects into a flow line. At least one of the connecting lines that is connected with the resistance element exhibits at least one bent point, which is held in at least one retaining opening formed in the protective bracket, whereby the connecting lines are stabilized. The temperature probe may be used for measuring the temperature of intake air in an intake pipe of a mixture-compressing, external-ignition internal combustion engine.

摘要： A method for measuring a propagation time difference includes: sending a transmitted ultrasound pulse, which is provided with a transmission reference instant and which includes an envelope and a carrier frequency, into a spatial region and receiving a received ultrasound pulse that corresponds to the transmitted ultrasound pulse transmitted. A coarse time difference is provided by comparing the transmission reference instant with an envelope of the received ultrasound pulse, for at least two cycles of transmission/reception in opposite directions of transmission. A fine time difference is provided by comparing the transmission reference instant with an instantaneous variation of the received ultrasound pulse, for the at least two cycles of transmission/reception in opposite directions of transmission.
