of ordinary skill in the art referring now to fig7 switches 404 410 are opened and switches 406 408 are closed while switches 412 418 are opened and switches 414 and 416 are closed as a result the charge values on the sampling capacitors are presented to the summers for the tip over determination as has been described above in another embodiment of the present invention a tip over sensor apparatus 800 as shown in fig8 includes an analog to digital converter adc 802 a positive summing junction sjp 804 and a negative summing junction sjn 806 the same programmable capacitors as described above in fig7 and their corresponding switches are used and function as has already been described it should be noted that the embodiment shown in fig8 depicts the sensor 302 as having differential x and z outputs such differential outputs are well known to those of ordinary skill in the art and the operations of the previously described embodiments although described as single ended signals for convenience could be easily modified for differential values as is well understood in one embodiment of the present invention the positive and negative summing junctions sjp sjn and the first and second summers 308 1 308 2 may be implemented using analog techniques with the summing junctions of opamps as known to one of ordinary skill in the art returning to the tip over sensor system 800 additional switches 810 824 are provided to couple the charges on the sampling capacitors to either of the positive or negative summing junctions 804 806 as will be described below referring to fig9 switches 404 404 1 410 410 1 412 412 1 418 and 418 1 are closed in order to acquire charge on the sampling capacitors subsequently those switches are.
