Systems, methods, and apparatus for detecting shifts in redundant sensor signals
First Claim
1. A method for detecting and indicating a shift in redundant sensor signals, comprising:
- receiving a sensor channel closeness signal for two or more redundant sensors;
receiving a spike confidence signal for at least one of the two or more redundant sensors;
receiving a spike duration signal for the at least one of the two or more redundant sensors;
determining a shift confidence based at least in part on the received sensor channel closeness signal, the received spike confidence signal, and the received spike duration signal; and
outputting the shift confidence, wherein the outputting of the shift confidence comprises logical multiplication of an inverted spike confidence signal and a channel closeness attribute, wherein the channel closeness attribute comprises a channel closeness signal delayed for a predetermined time defined by the spike duration signal, and wherein an output of the logical multiplication sets a latch, and wherein the latch is reset by the channel closeness signal being true, and wherein an output of the latch is inverted and interpreted as the shift confidence.
