Patent ID: 7369038

Claim:
A computer monitoring system for notifying a referee when a player or associated sports ball has passed beyond a predetermined boundary line defined on a playing surface, said computer monitoring system comprising: a processor: a plurality of sensors electrically coupled to said processor, said sensors being selectively positioned beneath the playing surface and registered directly below the predetermined boundary line, said sensors being connected in parallel to said processor such that each said sensor is independently activated during game playing conditions, each said sensor generating an analog output signal when a predetermined weight limit is detected thereon during game play; an analog-to-digital converter electrically coupled to said processor and said sensors, said converter receiving and converting said analog output signals to digital output signals; a memory including programmable software instruction that cause said computer monitoring system to perform a series of operations including the steps of: a. determining an originating location of said digital output signals, b. determining a sequential order of said digital output signals, c. calculating a time span between consecutive digital output signals, and d. determining whether said time span is greater than a predetermined threshold interval; wherein said processor generates and transmits audible and visual notification signals for each said consecutive digital output signals when said time span is greater than said threshold interval, a later one of said consecutive digital output signals being ignored by said processor when said time span is less than said threshold interval.
