Abstract
Described herein is the sensor assembly and method for rapidly obtaining accurate readings of a variable. The sensor assembly comprises a plurality of sensors which are connected to a microcontroller that processes the signals of the individual transducers to the microcontroller. The microcontroller contains software that maximizes the refresh rate and/or minimizes the time it takes to process the outputs of each of the transducers. The microcontroller that is coupled to the sensor assembly selectively measures the outputs of each transducer so as to speed up the refresh rate of the sensor.

7. A pressure sensor assembly, comprising:
-
a plurality of pressure sensors, each capable of detecting a reference pulse and a pulse responsive to pressure; and a microcontroller for measuring the two pulses detected by each of the plurality of pressure sensors, such that the reference pulse of a particular sensor is used to compensate for the environmental effects on the pressure pulse detected by that same sensor to determine the pressure on a particular sensor;
wherein the microcontroller determines which pulses of which sensors are measured. - View Dependent Claims (8)

9. A method for detecting the pressure in an automatic transmission having a plurality of clutches and an ECU, comprising the steps of:
-
coupling each of the clutches to a sensor located within a pressure assembly comprising a plurality of sensors; detecting the pressure of each clutch as needed by detecting the pressure on the corresponding sensor a selected number of times and thereafter using the reference output detected by that sensor to compensate for the environmental effects on that sensor so that the true pressure may be obtained. - View Dependent Claims (10, 11, 12)
