Systems and methods for monitoring the quality of water or leaks within a household plumbing system via machine learning are provided. Appliances can be connected to a plumbing system, wherein each appliance includes one or more sensors configured to output sensor data regarding a property of the water being utilized by that appliance. A processor is programmed to receive the sensor data and establish boundaries of normal operation. Then, when additional sensor data is received, the processor uses machine learning to classify that sensor data as being either within normal operation, or outside the bounds of normal operation. If the sensor data indicates the water property is outside the bounds, an output signal can be generated to inform the user.

System for sensing water quality or leaks using appliance data and machine learning

Systems and methods are disclosed for detecting a crack in an automotive windshield and alerting a user of the same. This can allow the user to repair the crack before the user might otherwise detect the crack by his/her own visual inspection. The windshield can be provided with emitters configured to emit signals (e.g., sound, light, etc.) and corresponding detectors configured to detect the emitted signals. Signal profiles or signatures can be stored that represent normal measurements when there is no crack. Upon detecting a signal signature that deviates from the stored normal signal signatures, the system can notify the user of a potential crack in the windshield. The system can also determine the location of the crack based upon which of the detectors detect a change in the detected signal.
