Patent ID: 7731602

Claim:
Apparatus adapted to control the operation of an assistive energy golf club head during a swing; said apparatus including: sensor apparatus adapted to sense the travel of said golf club head relative to a golf ball; signal processing apparatus effective during said swing and prior to the impact of a face of said golf club head with said golf ball to generate a firing command under control of an approach parameter; velocity generating apparatus including said golf club head responsive to said generation of said firing command to apply assistive energy from said golf club face to said golf ball; said assistive energy is effective to apply incremental velocity to said golf ball; said apparatus further including an assistive energy source for applying said assistive energy; said signal processing apparatus is effective during said swing to determine a pretrigger time at which said firing command should be to applied to said assistive energy source; said signal processing apparatus is further effective at said determined pretrigger time to generate said firing command; said assistive energy source is responsive to the generation of said firing command to apply assistive energy to said velocity generating apparatus; said velocity generating apparatus is responsive to the receipt of said assistive energy to impart said incremental velocity to said golf ball upon impact of said golf ball with said golf club face; and said pretrigger time is a function of club head performance information; said club head performance information includes golf ball velocity as a function of a delta-t time, where said delta-t time is the time interval in advance of said time of impact to generate said firing command.
