摘要： A detachable, articulated rotating eddy current inspection tool includes a body member (100) having a connector (110) at one end for mechanically and electrically attaching the body member to a rotating drive member (20) while at the other end, an eddy current probe (130) is supported for radial movement with respect to the axis of rotation of the body member. A motor (140) located within the body moves a mechanically variable mechanism (120) on which the probe is mounted. An encoder (150) housed within said body member senses the location of said eddy current probe with respect to the axis of rotation of said body member. A rotary transformer (50) is used to transfer probe position control signals and to receive information from the eddy current probe and the encoder.

摘要： The present invention is a brake control system (10) for preventing the skidding of a wheel on a surface. The phase relationship between the brake pressure (16) applied to the brakes and the torque (18) created from the braking applied is determined. This relationship allows the present brake control system (10) to maintain the wheels from skidding on a surface by maintaining a positive slope of such brake pressure (16) and torque (18) phase relationship. A second embodiment provides a backup system wherein the percentage of slip (120) is determined and compared to an input percentage slip (112). The second embodiment system overrides the torque command system (126) when the torque command system (126) fails.

摘要： A detachable, articulated rotating eddy current inspection tool (10) includes a body member (30) having a connector at one end for mechanically and electrically attaching the body member (100) to a rotating drive member while at the other end an eddy current probe (130) is supported for radial movement with respect to the axis of rotation of the body member. A motor (140) located within the body moves a slide on which the probe is mounted while at the same time a counterbalancing slide is moved radially in the opposite direction to maintain said tool in dynamic balance. An encoder (150) housed within said body member senses the location of said eddy current probe with respect to the axis of rotation of said body member. A rotary transformer (50) is used to transfer signals which control the position of the probe (130) and to receive information from the eddy current probe (130) and the encoder (150). The encoder output signals are modulated by the eddy curent probe exciter signal to enable probe position information to be sent through a rotary transformer (50).
