The present invention provides a solid golf ball which gives a superior shot feeling to the golfer and exhibits stabilized repulsion performance when it is hit at any head speed. A plurality of keys are located above the intersections and exert force on the conductors and FSR elements during key presses. The vehicle control system further includes a monitoring control device having a control circuit that is different from the by-wire control circuit and that monitors the by-wire system on the basis of monitoring information received from the by-wire system. An adjustment mechanism is also provided for releasably adjusting the distance between the magnets and the elongate strip. In this regard, a representative method includes: receiving information from multiple test systems regarding a first airflow parameter of a gas turbine engine component; and using the information to establish a desired performance parameter that is to be exhibited by a repaired component.
