Abstract: A combination flux loop and B-dot probe comprising a single mineral insulated cable having an outer sheath of, e.g., stainless steel or the like, and three (3) conductors positioned within the sheath and embedded in a mineral insulator such as, e.g., MgO. One of the conductors forms a flux loop having a single loop and second and third conductors forming a B-dot probe comprises a single wire having a double loop. The combination probe is configured to prevent twisting of the conductors along a curved bend as the combined probe is fashioned into a curved shape. To prevent twisting, the conductors may be formed as ribbon wires having a generally flat, rectangular shaped cross-section and/or the sheath may have a generally oval or rectangular shaped cross-section.

Abstract: A method and apparatus for undertaking control measurements of a measurement object such as a motor vehicle frame or unit installed thereon, in which a directional beam or beams are used which extend only parallel to one coordinate axis and in which only one light source is used which emits directional beams toward one or two sides; only one parallel guidance coordinated thereto is provided which is securely connected at least indirectly with the vehicle, extending preferably perpendicularly to the vehicle longitudinal axis underneath the vehicle floor; the position of the control points perpendicular to the direction of the parallel guidance will be determined by direct mechanical measurements of the distance between the corresponding plumbing rulers, on the one hand, and the parallel guidance or a fixed point at the beam source, on the other.
