Self-cleaning substrate

A self-cleaning substrate system, comprising:

• a substrate;
• a plurality of ultrasound emitters coupled to the substrate, wherein the ultrasound emitters are arranged in an array along the substrate;
• a circuit configured to determine a characteristic of the substrate;
• a power source;
• and
• a controller operatively coupled to the plurality of ultrasound emitters mechanisms, the circuit, and the power source;
• wherein the circuit provides a feedback signal indicative of the detected characteristic to the controller;
• wherein the controller is coupled to each of the plurality of ultrasound emitters and is configured to individually activate and deactivate the ultrasound emitters based on the feedback signal to selectively clean a localized area of the substrate.

A self-cleaning substrate system, comprising:

• a substrate;
• a frame surrounding a periphery of the substrate;
• an ultrasound emitter coupled to the frame, wherein the ultrasound emitter is configured to emit ultrasonic waves into the substrate;
• a circuit configured to determine a characteristic of the substrate;
• a power source;
• and
• a controller operatively coupled to the ultrasound emitter, the circuit, and the power source;
• wherein the circuit provides a feedback signal indicative of the detected characteristic to the controller;
• wherein the controller is configured to activate and deactivate the ultrasound emitter based on the feedback signal to selectively clean an area of the substrate.
