Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
302 words
Means for transmitting auxiliary display information on a standard video or audio radio frequency communication system having a transmitter radiating a radio frequency carrier which is detectable by a standard television or radio receiver for presenting the standard video or audio information and further including an auxiliary information display device connected to said standard television or audio receiver and including a pair of counters for displaying scores thereon; a first tone generator at said transmitter producing an output at a first frequency, a first keying means connected to said first tone generator and said first tone generator connected to said transmitteR so as to modulate said radio frequency carrier with said first frequency when said first keying means is energized; a second tone generator at said transmitter producing an output at a second frequency, a second keying means connected to said second tone generator and said second tone generator connected to said transmitter to modulate said radio frequency carrier with said second frequency when said second keying means is energized; a third tone generator at said transmitter producing an output at a third frequency, a third keying means connected to said third tone generator and said third tone generator connected to said transmitter so as to modulate said radio frequency carrier with said third frequency when said third keying means is energized; said auxiliary information display including first, second and third detectors tuned respectively to said first, second and third frequencies; the output of said first detector connected to the first one of said pair of counters to drive it, the output of said second detector connected to the second one of said pair of counters to drive it, and reset means for resetting said pair of counters to zero and the output of said third detector connected to said reset means.

Claim 3
Dependent Claim
42 words
Means for transmitting auxiliary information according to claim 1 wherein said first and second counters each include ratchet wheels for driving said counters, ratchet relays receiving the outputs of said first and second detectors and having ratchets engageable with said ratchet wheels.
Claim 4
Dependent Claim
46 words
Means for transmitting auxiliary information according to claim 2 wherein each of said counters is spring-biased to a zero position and reset relays are connected to each of said ratchets to move them out of engagement with said ratchet wheels so that they return to zero.
