Patent attributes
An obstacle detection system includes a light emitter that emits a light signal and a light detector configured to receive a portion of the light signal reflected back from an object. The system includes a processor operatively coupled to the light emitter and the light detector to determine a presence of an obstacle based on the portion of the light signal received by the light detector. The system includes a heater operatively coupled to a power source and at least one sensor configured to determine an ambient temperature and an ambient relative humidity. The processor is operatively coupled to the power source, the heater, and the at least one sensor. The processor is configured to calculate a dew point of the environment from the ambient relative humidity and the ambient temperature and to activate the heater in response to the ambient temperature being less than the dew point.
