ABSTRACT:
An array of piezoelectric ceramic sensors affixed to a flexible plastic membrane forms a target surface and the signals produced by the sensors are processed to produce an output signal which indicates the location where a liquid stream strikes the target. The sensor array is used to detect the presence and location of a liquid stream from a pressurized nozzle used to play an interactive game. The stream presence and position signals are fed in real time to a (personal) computer which produces an output display indicating where the target was struck by the stream. The stream detection array may be used in a variety of applications.
