The system includes a window which acts as a microphone using a piezoelectric transducer that captures resonance on an outside surface of the vehicle window when pressure waves (e.g., voice commands or taps) impact it. To recognize this sound, a transducer controller amplifies vibrations from the window tap or spoken commands. The system may include a low-power mode that listens for input while the vehicle is off. In a second, high-power mode, the system may detect a tapping event, which may prompt a transition to a wake-up state. The system may associate a number and timing of taps with unique user keys, similar to key selections of numbers on a keypad. The system may also recognize verbal PIN code input using the piezoelectric transducer microphone."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for windows as a microphone keypad entry","description":"Disclosed is a system that uses a window as a microphone as a replacement for keyless entry to a vehicle.
