Patent ID: 11933678
Assignee: JOHNSON CONTROLS TYCO IP HOLDINGS LLP
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 8:
9. A device in a building control system, the device comprising:
a first temperature sensor configured to generate a first temperature measurement that is indicative of a measured ambient temperature near the device, wherein heat generated by electronic components of the device affects the measured ambient temperature causing the first temperature measurement to be inaccurate relative to an actual ambient temperature value;
a relay configured to control an amount of electrical energy powering the device;
a display configured to provide a user interface to a user of the device; and
a processing circuit comprising a second temperature sensor configured to generate a second temperature measurement that is indicative of a temperature of the processing circuit, the processing circuit configured to:
obtain the first temperature measurement from the first temperature sensor;
obtain the second temperature measurement from the second temperature sensor;
determine a brightness level associated with the display;
determine a state of the relay;
provide the first temperature measurement, the second temperature measurement, the brightness level, and the state of the relay as input to a neural network; and

determine the actual ambient temperature value associated with the measured ambient temperature near the device based on an output of the neural network.
