A system and method for determining an amount and direction of a golfer’s head movement as the golfer executes a golf swing. A composition containing, as an active ingredient, a rare saccharide which is introduced into physiological-activity sensitive cells and has an effect of modifying the function of the cells. If an impact on the vehicle creates an acceleration force above a predetermined level, the inertia device moves to break the transmission path, preventing the latch from being unlatched. The example system also includes a receiver configured to receive radar signals returned in response to said transmitted radar signal pulses, and a processor configured to extrapolate said received signals to said full bandwidth, to thereby create high resolution SAR images. When the non-delayed signal reaches its peak and turns downward, the delayed input signal is still rising and crosses over the first pulse, creating a change of state at the comparator output to a high or active state.
