Claim Text:
1. An overheat sensor system comprising: a controller comprising a processor and a tangible, non-transitory memory; a sensor bus in logical communication with the controller; and a first sensor in logical communication with the controller via the sensor bus and configured to receive first infrared radiation from a first location under observation; a second sensor comprising an acoustical sensor in logical communication with the controller via the sensor bus and configured to detect flying debris capable of impeding the operation of the first sensor; and avionics comprising an aircraft data bus whereby avionics input data indicating a mode of flight is provided to the controller, wherein the controller is configured to take a first action in response to the mode of flight and a first indication that the first infrared radiation from the first location exceeds a first threshold corresponding to the mode of flight, and wherein the first sensor comprises a temperature-sensing element configured to detect infrared radiation with a wavelength between 700 nm and 1 mm and a fire-sensing element configured to detect infrared radiation with a wavelength less than that of the temperature-sensing element, whereby each is configured to detect the first infrared radiation from the first location.
