The invention provides a system and method of providing protection against the effects of protons of solar origin, so as to make it possible for a start sensor to be reconfigured. A seat bottom has an arm extending therefrom which is pivotally engaged to the seatback at a location offset from the seatback pivot with the stanchions. A support portion of the plate is provided distal of the bone pegs and supports comminuted bone fragments. Subsequently, a layer of dielectric material is formed within the hole, over and radially inwardly of the conductive material. According to the apparatus mentioned above, there is no difficulty in movement of the subject to be inspected when the conveying table rotates continuously in a prescribed direction during its operation for inspection and during its operation for verification of accuracy of the apparatus as well.
