    摘要: A miniature pressure scanning system may comprise: a plurality of miniature pressure sensors including a plurality of sensor outputs, each of the miniature pressure sensors including at least one sensor output for providing an analog output signal and each at least one sensor output having an associated output impedance; a plurality of buffers, each buffer of said plurality of buffers being electrically coupled to one sensor output of the plurality of sensor outputs, and each said buffer being operative to reduce a settling time constant associated with multiplexer voltage spikes and reduce the associated output impedance of the one sensor output coupled to it; and at least one multiplexer electrically coupled to the plurality of sensor outputs, said at least one multiplexer being operative to be switched between each of the plurality of sensor outputs.

    摘要: A data collection system includes a plurality of sensor modules each provided with a sensor unit, and a data collecting device. The data collecting device (200) is provided with: a clock output unit (201) which outputs a clock signal; an enable signal output unit (202) which outputs to a prescribed sensor module (100) an enable signal at intervals equal to or greater than the number of clock signals corresponding to the number of sensor modules (100); a counter (203) which counts the number of clock signals; and a sensor signal input unit (205) into which data output by the sensor modules (100) is input via a bus line, and which records said data in association with the count value. Using the clock signal as a trigger, each sensor module (100) functions as a shift register feeding the enable signal to the subsequent stage sensor module (100), and each sensor module (100) outputs output data from the sensor unit (110) in said sensor module (100) to the sensor signal input unit (205) only when the enable signal has been fed to said sensor module (100).
