An apparatus for measuring hydrogen content and partial hydrogen pressure in gas streams and a method of modeling the sensor based on the characteristics of the sensor. Each of the static base plate and the dynamic moving plate defines six spherical ball sockets. The deposited connector terminals do not require a special lever for adjusting contact pressure. When, however, it is determined that the golfer’s swing technique is fine, then collecting data related to how the golfer’s swing launches a golf ball. Duplicate suspects undergo further processing.
