US12480747 - Circuitry to detect difference between lead line and target hits

Circuitry for use in connection with a conductive target may include an interface, a conductive target zone, a plurality of conductive lead lines electrically connecting the interface to the at least one conductive target zone, and at least one processor. The at least one processor may detect via the interface, a first electrical signal representing severance of a portion of the conductive target zone by a projectile hit within the at least one conductive target zone; detect via the interface a second electrical signal, different from the first electrical signal, wherein the second electrical signal represents severance of one of the plurality of lead lines by a projectile hit on the one of the plurality of lead lines; trigger an indicator of a target hit in response to the first electrical signal; and prevent triggering of the target hit indicator in response to the second electrical signal.

The patent describes circuitry designed to differentiate between hits on a conductive target and hits on lead lines connecting to the target, utilizing an interface and a processor. The processor detects distinct electrical signals for each type of hit, triggering an indicator for target hits while preventing false indicators from lead line severance.

Claim 1

1 . Circuitry for use in connection with a conductive target having an interface, at least one conductive target zone and a plurality of conductive lead lines electrically connecting the interface to the at least one conductive target zone, the circuitry comprising: at least one processor configured to: detect via the interface, a plurality of first electrical signals representing severance of portions of the at least one conductive target zone by projectile hits within the at least one conductive target zone; detect via the interface a plurality of second electrical signals, different from the first electrical signals, wherein the second electrical signals represent severance of the plurality of lead lines by projectile hits on one of the plurality of lead lines; trigger an indicator of a target hit in response to at least one of the first electrical signals; and prevent triggering of the target hit indicator in response to at least one of the second electrical signals. at least one processor configured to: detect via the interface, a plurality of first electrical signals representing severance of portions of the at least one conductive target zone by projectile hits within the at least one conductive target zone; detect via the interface a plurality of second electrical signals, different from the first electrical signals, wherein the second electrical signals represent severance of the plurality of lead lines by projectile hits on one of the plurality of lead lines; trigger an indicator of a target hit in response to at least one of the first electrical signals; and prevent triggering of the target hit indicator in response to at least one of the second electrical signals. detect via the interface, a plurality of first electrical signals representing severance of portions of the at least one conductive target zone by projectile hits within the at least one conductive target zone; detect via the interface a plurality of second electrical signals, different from the first electrical signals, wherein the second electrical signals represent severance of the plurality of lead lines by projectile hits on one of the plurality of lead lines; trigger an indicator of a target hit in response to at least one of the first electrical signals; and prevent triggering of the target hit indicator in response to at least one of the second electrical signals.
