Abstract: A transmitter arranged in a tire includes a transmitting section, which has a terminal, and a pressure switch. The pressure switch includes a hollow box and a passage that causes an interior of the box and an interior of the tire to communicate with each other. The box includes a conductive deforming portion, which is separate from the terminal when the difference between the pressure in the box and the pressure in the tire is less than a predetermined value and is elastically deformed to contact the terminal when the pressure in the box is higher than the pressure in the tire at least by the predetermined value. The transmitting section transmits a warning signal that causes a tire pressure warning device to issue a warning in response to contact between the deforming portion and the terminal.

Abstract: A method and system for assessing the condition of a pipeline in a pipeline system is disclosed. The method includes generating a pressure wave in the fluid being carried along the pipeline system at a pressure wave generating location along the pipeline system and detecting pressure wave interaction signals at two closely spaced measurement locations along the pipeline. The method then includes determining a system response function for the pipeline based on the detected pressure wave interaction signals for each measurement location and characterising the pipeline based on the system response function.

Abstract: Apparatus and associated methods relate to generating redundant measurement of pseudo differential pressure using two absolute-pressure sensors, each exposed to a different environment. Each of the two absolute-pressure sensors has complementary first and second output nodes. The first output node has a positive relation with and/or response to increasing pressure, while the second output node has a negative relation with and/or response to increasing pressure. A first difference measurement signal is calculated based on a difference between the positive relation output signals of the first and second absolute-pressure sensors. A second difference measurement signal is calculated based on a difference between the negative relation output signals of the first and second absolute-pressure sensors. Both the first and second difference measurement signals are indicative of a pressure difference between the first and second environments. Such redundant measurement of differential pressure can advantageously provide continuous pressure-difference measurement in spite of various component failures.

Abstract: A method for operating a common-rail system of a motor vehicle that includes a common-rail-pressure sensor configuration having at least two signal paths, and that can be operated at a maximally permissible common-rail pressure and at a minimally permissible common-rail pressure. Sensor signals are read out in each case in response to a pressure measurement in a common rail of the common-rail system via the at least two signal paths, and a signal deviation value is ascertained that characterizes a deviation between the pressure values that are each determined on the basis of the sensor signals. The method includes reducing the maximally permissible common-rail pressure by a correction value to a maximally permissible emergency common-rail pressure and/or increasing the minimally permissible common-rail pressure by a correction value to a minimally permissible emergency common-rail pressure in response to the signal deviation value exceeding a predefined value.
