Abstract
A durable, rigid, low-cost device to sense an impact of a ball over a wide area and to provide response to a user that said impact has occurred. The sensing mechanism is a low-cost acoustic sensor, acoustically coupled to an essentially single sheet of plastic material. Sensor electronics filter the input and measure amplitude to determine if a valid hit has occurred. If so, the device reports an activate signal to the response electronics that in turn provide feedback to the user by playing a digitally recorded audio message, recorded specifically for the event. Variously, the activate signal may be transmitted to a remote device that contains the response electronics.
