Abstract
Abstract A sports impact sensing target reports a sensed impact to a remote location without interference with the operation of like impact sensing targets that are proximately located. The sports impact target reports each sensed impact with a selected modulated signal that can be selected readily to distinguish it from the report signals produced by other proximate impact sensing targets.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
Sports target apparatus for operation without signal interference with other proximately located such apparatus, said apparatus comprising a) a first piezo film impact transducer having a surface exposed for impact by a sports implement and producing an impact responsive electrical signal in response to impact, b) an impact reporting transmitter connected to respond to an impact responsive signal from said impact transducer for broadcasting a selected modulated carrier signal, said transmitter including first selection means for broadcasting only one of a first set of different modulated carrier signals, c) an impact reporting receiver arranged for receiving the selected modulated carrier signal and for producing in response thereto an impact responsive output signal, said impact reporting receiver including second selection means for receiving only one of said first set of different modulated carrier signals, and d) an output unit for responding to the import responsive output signal from said receiver to produce a selected perceptible report of impact on the transducer, so that first and second proximately located target apparatus can each operate with different modulated carrier signals and thereby avoid signal interference with one another.
Claim 2
Dependent Claim
185 words
Sports target apparatus for operation without signal interference with other proximately located such apparatus, said apparatus comprising a) a first piezo film impact transducer having a surface exposed for impact by a sports implement and producing an impact responsive electrical signal in response to impact, b) an impact reporting transmitter connected to respond to an impact responsive signal from said impact transducer for broadcasting a selected modulated carrier signal, said transmitter including first selection means for broadcasting only one of a first set of different modulated carrier signals, c) an impact reporting receiver arranged for receiving the selected modulated carrier signal and for producing in response thereto an impact responsive output signal, said impact reporting receiver including second selection means for receiving only one of said first set of different modulated carrier signals, and d) an output unit for responding to the import responsive output signal from said receiver to produce a selected perceptible report of impact on the transducer, so that first and second proximately located target apparatus can each operate with different modulated carrier signals and thereby avoid signal interference with one another.
Claim 3
Dependent Claim
107 words
Sports target apparatus according to claim 1 further a) at least a second impact transducer input disposed at a different location from said first impact transducer; for exposure to differently located impacts, b) at least a second transmitter, connected to respond to an impact responsive signal from only said second transducer, c) at least a second receiver arranged to receive the modulated carrier signal of only the said second transmitter, and d) in which said output unit responds to each said receiver and produces a report in response to said first receiver at least in part different from the report produced in response to said second receiver.
Claim 4
Dependent Claim
42 words
Sports target apparatus according to claim 1 in which said transmitter includes means for broadcasting each modulated carrier signal in said first set thereof with a carrier frequency different from the carrier frequency of other said signals in said first set thereof.
Claim 5
Dependent Claim
29 words
Sports target apparatus according to claim 1 in which each of said first selection means and of said second selection means includes a set of manually operable selection switches.
