US Patent 10282957 Overheat detection systems and methods

A system for detecting an overheat condition in a confined space includes a sensing device and one or more processors. The sensing device is attached to a wall of the confined space. The sensing device includes a laser range sensor, a thermal imaging sensor, and a wireless communication circuit. The laser range sensor measures a distance from the sensing device to a target object within the confined space. The thermal imaging sensor measures thermal radiation emitted from the target object. The wireless communication circuit remotely communicates distance data representing the distance measured by the laser range sensor and radiation data representing the thermal radiation measured by the thermal imaging sensor. The one or more processors are configured to determine a temperature of the target object based on the distance data and the radiation data.
