Application ID: 13084796

Base Claim:
1. A hazard detection system, the system comprising: a plurality of sensors configured to measure attributes associated with a hazard and generate sensor readings; and a detection device configured to determine whether the hazard exists or not based on a fuzzy analysis of the sensor readings, wherein: the sensor readings include temperature readings: and the fuzzy analysis comprises: determining a temperature rise rate from the temperature readings; classifying the temperature rise rate by assigning a classification value in the range 0 to 1; categorizing the temperature rise rate and the temperature readings into respective fuzzy set categories; and combining the respective fuzzy set categories into an output that indicates whether the hazardous condition exists or not.

Claim 6:
6. The system of claim 1 , wherein: the detection device comprises a classifier module configured to assign classification values to the sensor readings using a neural network, wherein the classification values lie in a range of 0 to 1.
