  • Publication number: 20180052455
    Abstract: A communication system includes a first communication device disposed onboard a displaced vehicle. The first communication device communicates with a second communication device onboard a lead vehicle of a vehicle system for the lead vehicle to remotely control operation of the vehicle system. The first communication device receives a reconfiguration signal from the second communication device. A remote control (RC) communication device is disposed onboard the first displaced vehicle. The RC communication device wirelessly receives a control signal from an operator control unit (OCU) for the OCU to remotely control the first displaced vehicle. A communication controller reconfigure the RC communication device to repeat the control signal from the OCU responsive to the first communication device of the first displaced vehicle receiving the reconfiguration signal from the second communication device of the lead vehicle or another reconfiguration signal from an off-board or on-board location.

  • Publication number: 20180051582
    Abstract: A brush seal has bristles with a free end sealing against a radially inward surface of a stationary component. The bristles are angled axially 15 degrees to 70 degrees, and circumferentially at an angle that is less than the axial angle. A retaining plate extends radially outward from the rotating component, and supports the bristles from centrifugal loading in an operative state of a turbomachine. A bristle shield extends radially outward along a length of the bristles, such that the bristle shield is configured to shield the bristles from flow during an operative state of the turbomachine. The bristles are located between the retaining plate and the bristle shield. A circumferential groove has a downstream side and an upstream side, and a side plate is attached to the upstream side. The fixed end of the bristles is attached to the upstream side of the groove by the side plate.

  • Patent number: 9895130
    Abstract: Systems, methods, and computer program products that enable calculating the water equivalent diameter of an exposed subject by defining a patient object using anterior/posterior (AP) and lateral (LAT) scout images are provided. Pixels corresponding to air in the LAT and AP scout image are determined. Pixels outside the of the air area belong to either to the patient or the table. The table for both the LAT and AP scout images is identified. The remaining pixels in the LAT AP scout images are from the patient. For each segmented object (patient or table) the boundaries of the segmented object are identified and the attenuations within the segmented boundaries are computed. The final shape and attenuation values of the patient is stored and the size-specific dose estimate (SSDE) is calculated. The water equivalent diameter value is normalized by using the technical acquisition parameters provided by the acquisition device.
