Matside wrestling scoreboard

Claim 2

Claim 4

A wrestling scoreboard according to claim 2 further comprising a period timer which includes both a timing device for visually displaying the time of a wrestling match period and a means for starting and stopping the timing device and for stopping the advantage time digital clock in synchronism with stopping the period timer timing device during a period whenever said digital clock is running at the time the timing device is stopped.

Claim 5

A wrestling scoreboard according to claim 3 further comprising match reset means for resetting the advantage time digital clock to prepare the advantage timer for the beginning of a new match.

Claim 6

A wrestling scoreboard according to claim 2 wherein the digital clock comprises: an increment-decrement counter for producing an output set of binary-coded decimal signals representative of time, which counter is responsive to a timing pulse to update the counter output in response to an indication from said sixth means of one of the wrestlers earning advantage time and in accordance with an indication from the fourth means that a said wrestler has or has not accrued a net advantage time to increment and decrement the clock output count.

Claim 7

A wrestling scoreboard according to claim 5 wherein the increment-decremeNt counter comprises: a unit seconds counter stage, tens seconds counter stage and a unit minutes counter stage, each of which counter stages has a set of data outputs for providing a digital representation of the count of the stage and each of which counter stages has a count up input, a count down input, a carry output and a borrow output, which unit minutes stage count up and count down inputs are coupled to the tens seconds count stage carry and borrow outputs respectively and which tens seconds count stage count up and count down inputs are respectively coupled to the unit seconds stage counter carry and borrow outputs; and, means for providing count signals to either the unit seconds stage counter count up or count down inputs according to said fourth means.

Claim 8

A wrestling scoreboard according to claim 2 wherein: the first means comprises an operator actuable switch and a set-reset register for each wrestler, a said switch when actuated producing an output signal which is stored in a said register and which is representative that the wrestler corresponding thereto is earning advantage time, which registers have their set inputs cross coupled to the reset input of the other register so that only one of the registers is in a set state at any given time; the second means comprises a clock decode circuit for decoding the digital clock to provide an indication that a wrestler is earning or has accrued a net advantage time for a clock decode not-equal-to-zero and to provide an indication that neither wrestler has accrued a net advantage time for a clock decode equal to zero; the third means comprises a net advantage time register which in response to an indication from the first means of a clock decode equal-to-zero, either, resides in a set state for an output from the first means representative that one of the first means registers is in a set state, or resides in a reset state for a first means output representative that the other first means register is in a set state; the fourth means comprises a pair of dual input coincidence gates and an OR gate, each of which coincidence gates has one input coupled to an output of the net advantage time register and its other input coupled to the set output of one of the first means registers, and both of which coincidence gates have their outputs connected to the OR gate inputs, whereby, both, when neither wrestler is earning advantage time and when one wrestler both is earning but has not accrued a net advantage time, the coincidence gates and the OR gate each reside in a first state, but when one of the wrestlers, both, is earning and has accrued a net advantage time, one of the coincidence gates resides in a second state and causes the OR gate to reside in a second state; the fifth means comprises a pair of dual input coincidence gates each of which has one input which is coupled to the clock decode means and which input is in an active state when the clock decode is not equal to zero, one of which coincidence gates has its other input connected to the reset output of the net advantage time register, and the other of which coincidence gates has its other input connected to the set output of the net advantage time register whereby when the clock decode is not equal to zero one or the other of the coincidence gates is in an active state in accordance with the state of the net advantage time register to activate the indicator associated with the active coincidence gate; and the sixth means comprises an OR gate connected to like outputs of the first means registers to provide an output indicative that a wrestler is earning advantage time when the states of said like outputs are not the same and for providing an indication that neither of the wrestlers is earning advantage time when the state of said like outputs are the same.

Claim 9

A wrestling scoreboard according to claim 7 wherein the clock control means comprises: means adapted to receive a wavetrain of timing pulses and, iN response to an indication from the sixth means of a wrestler earning advantage time, selectively passes said timing pulses on either an increment or a decrement output lead in accordance with an indication from the fourth means that the wrestler earning advantage time has or has not accrued a net advantage time; and wherein the digital clock comprises: an increment-decrement counter for producing an output set of binary-coded-decimal signals representative of advantage time in response to count signals, which counter has a count up input and a count down input coupled to receive timing pulses from the clock control increment and decrement output leads respectively as count signals.

Claim 10

A wrestling scoreboard according to claim 8 wherein the digital clock comprises: a unit seconds counter stage, a tens seconds counter stage and a unit minutes counter stage, each of which counter stages has a set of data outputs for providing a digital representation of the count of the stage and each of which counter stages has a count up input, a count down input, a carry output and a borrow output, which unit minutes stage count up and count down inputs are coupled to the tens seconds count stage carry and borrow outputs respectively and which tens seconds count stage count up and count down inputs are respectively coupled to the unit seconds stage counter carry and borrow outputs; and, wherein the clock control means comprises: an input gate, which input gate is a coincidence gate having one input coupled to receive a wavetrain of timing pulses and having another input coupled to said sixth means whereby said input gate passes timing pulses on its output in response to an indication from the sixth means of a wrestler earning advantage time; and a pair of output gates the respective outputs of which are the clock control increment and decrement output leads, which output gates are each dual input coincidence gates, which output gates each have one input coupled to the output of said input gate and the other of its inputs coupled to the fourth means, and which other inputs are respectively active in response to an indication from the fourth means that a wrestler has and to an indication that neither wrestler has accrued a net advantage time.

Claim 11

A wrestling scoreboard according to claim 9 further comprising: a digital match score display, a digital match display, and a digital team score display, each of which displays include a counter stage for each digit of the display; and, wherein the match reset means includes means for clearing each advantage time register, each advantage time clock counter stage, and each period timer timing device counter stage, and includes means for clearing each match score display.

Claim 12

A wrestling scoreboard according to claim 10 further comprising a pre-set circuit for presetting the advantage time clock to a predetermined count.

Claim 13

A wrestling scoreboard according to claim 11 wherein the pre-set circuit comprises means for coupling a count up signal to the unit minutes counter stage and a clear signal to the unit and tens seconds stages.
