SYSTEM AND METHOD FOR TESTING SEAT PRESSURE SENSOR
First Claim
1. A system comprising a computing device having a processor and a memory, the memory storing instructions, the instructions comprising programming to:
- receive a measurement of a pre-installation pressure offset of a bladder of a pressure sensing assembly measured before installation of the pressure sensing assembly into a seat;
receive a weighted measurement from the pressure sensing assembly in the seat when a loading device applies weight to the seat and an empty seat measurement from the pressure sensing assembly in the seat when the loading device does not apply weight to the seat;
determine a threshold value by subtracting the empty seat measurement from the weighted measurement;
determine a seat pressure offset value by subtracting the pre-installation pressure offset from the threshold value; and
compare the seat pressure offset value to a selected range.

Abstract
A system for testing a pressure sensor of a seat includes a loading device and a processor. The loading device removably applies weight to the seat. The processor receives a measurement of a pre-installation pressure offset of a bladder of the pressure sensor measured before installation of the pressure sensing assembly into the seat. The processor is programmed to receive a weighted measurement from the pressure sensor in the seat when the loading device applies weight to the seat and an empty seat measurement from the pressure sensor in the seat when the loading device does not apply weight to the seat. The processor determines a threshold value by subtracting the empty seat measurement from the weighted measurement. The processor determines a seat pressure offset value by subtracting the pre-installation pressure offset value from the threshold value. The processor compares the seat pressure offset value to a selected range.

8. A method of testing a pressure sensing assembly of a plurality of seats, the method comprising:
-
measuring a pre-installation pressure offset of a bladder of each pressure sensing assembly before installation of the pressure sensing assembly into the respective seat; applying weight to each seat; measuring a weighted measurement with each pressure sensing assembly in the respective seat when the loading device applies weight to the respective seat; measuring an empty seat measurement with each pressure sensing assembly in the respective seat when the loading device does not apply weight to the respective seat; determining a seat pressure offset value by subtracting the pre-installation pressure offset and the empty seat measurement from the weighted measurement for each seat; comparing the seat pressure offset value of each seat to a selected range; and modifying each seat having the seat pressure offset value outside of the selected range. - View Dependent Claims (9, 10, 11, 12, 13, 14)
