Liquid stream analysis and feedback system with acoustic filtering method
摘要：
A facility for the purpose of entertainment, education, or monitoring wherein there is provided an acoustic sensor (24) mounted on the outside of a toilet bowl (30) and a simple, inexpensive target (22) mounted to the inside of the toilet (28) thereby keeping the sensitive acoustic sensor and other electronics in a dryer and cleaner location. The sound of a urine stream contacting the target (22) propagates through the toilet (26) and is detected by the acoustic sensor (24). An analysis and feedback unit (32) monitors the sound of the urine stream contacting the target (22) and provides a message to the user indicating their success in hitting the target (22) with the urine stream.
