摘要： A remotely interrogatable pressure transition indicator (100) having a pressure sensitive element (110) interacting with a remotely interrogatable mechanical switch (120). The pressure sensitive element (110) is a hermetically sealed, gas impermeable, flexible walled sachet (110) containing a quantity of gas, operable for transitioning between inflated and deflated conditions induced by a change in external gaseous pressure experienced by the sachet (110). The sachet (110) interacts with the mechanical switch (120) to producing a first interrogatable value when the sachet (110) is inflated and a second interrogatable value when the sachet (110) is deflated.

摘要： A method for detecting an error in a bridge sensor which is adapted for measuring a physical parameter. The method comprises biasing a first contact pair of the bridge sensor at least two times in a first direction and at least one time in a second direction opposite to the first direction; while biasing the first contact pair, measuring an output signal on a different contact pair of the bridge sensor, thus obtaining at least three output measurements which are representative for the physical parameter and which are separated by time intervals; combining the output measurements to obtain an output value which is indicative for an error in the bridge sensor, wherein the output measurements which are combined are only those output measurements which are measured when biasing the first contact pair.

摘要： A semiconductor device 3 for sensing a physical quantity adjusts the output characteristic of a pressure sensor, for example, based on trimming data stored in an EPROM 34. A comparator 311 compares an input voltage given to a terminal 43 and a predetermined reference voltage, and delivers a write control signal for EPROM 34. When the comparator 311 delivers a Low signal for the EPROM 34, a first gate circuit 312 provided between the terminal 43 and a temperature sensor 32 connects the terminal 43 and the temperature sensor 32. A second gate circuit 313 provided between the terminal 43 and a pull-down resistor 314 disconnects the terminal 43 and the pull-down resistor 314. The operational voltage of the temperature sensor 32 is lower than the reference voltage, and the terminal 43 is used as an output terminal for the temperature sensor 32.
