Application: Silent detection of open or short connections to a piezoelectric device (Patent ID: US20230326441A1)
The patent filed by Microchip Technology Inc. describes an apparatus that includes a test circuit and a control circuit to determine whether to operate in a silent test mode or a normal mode. In the normal mode, the driver circuit drives a piezoelectric horn to output sound, while in the silent test mode, the horn generates a silent piezoelectric response for evaluation. The control circuit can detect issues like short circuits or open terminals in the piezoelectric horn based on received signals.
The apparatus also includes various claims detailing the operation of the control circuit in the silent test mode, such as driving the horn with a ramped voltage, using a current limited source, and measuring responses from different terminals. The method outlined in the patent involves determining the operating mode, driving the horn accordingly, and evaluating its performance based on received signals. Overall, the patent focuses on a method and apparatus for effectively testing the functionality of a piezoelectric horn without generating audible noise during the evaluation process.
