Abstract:
1. A leak detection method for an air bed having a first chamber and a second chamber, the method comprising: adjusting the first and second chambers to an initial pressure level; sensing a first pressure value of the first chamber and a first pressure value of the second chamber after a first time interval; sensing a second pressure value of the first chamber and a second pressure value of the second chamber after a second time interval; determining a pressure change of the first chamber; determining a pressure change of the second chamber; comparing the pressure change of the first chamber with the pressure change of the second chamber to determine if there is a leak in the first chamber or the second chamber; and displaying a leak detection indicator based upon the pressure changes of the first and second chambers; wherein a leak detection indicator signifying that both the first chamber and the second chamber are leaking is displayed when the pressure changes of the first and second chambers both exceed a maximum acceptable pressure change value.
