Abstract: Method and apparatus for enabling ultrasonic inspection of a changing, insufficiently defined or unknown shape (e.g., a variable radius or a noncircular radius caused by the use of soft tooling) at a rate that meets production requirements. The apparatus comprises a linear ultrasonic array (i.e., sensor) incorporated in a toppler, which in turn is slidably supported by an oscillating sensor mechanism carried by a traveling trailer vehicle. As a result of this arrangement, the sensor can undergo a back-and-forth sweeping motion coupled with motion along the spar radius. The sensor is further able to displace radially relative to a sweep pivot axis and rotate (hereinafter “topple”) about a topple pivot axis. In this manner, the orientation of the sensor can adjust to the contour of the inspected surface as the sensor scans.

Abstract: System and method for enabling ultrasonic inspection of a variable and irregular shape. The system comprises one or more ultrasonic pulser/receivers, one or more ultrasonic transducer arrays, a shoe or jig to hold and position the array(s), data acquisition software to drive the array(s), and data analysis software to select a respective best return signal for each pixel to be displayed. This system starts with information about the general orientation of the array relative to the part and a general predicted part shape. More specific orientation of the transmitted ultrasound beams relative to the part surface is done electronically by phasing the elements in the array(s) to cover the expected (i.e., predicted) surface as well as the full range of part surface variability.

Abstract: A first unit configured to generate and transmit a code of positive and negative DC pulses through a first rail of a railway. A second unit spaced from the first unit and configured to sense the code, which includes a leading code word, having a positive or negative timing pulse followed after a first data interval by a positive or negative data pulse, followed by a modifying code word. The modifying code word consists of a second positive or negative timing pulse followed after a second data interval by a second positive or negative data pulse. The second timing pulse starts after one code cycle from the start of the leading code word timing pulse. The second timing pulse and the second data pulse duplicate the timing pulse and the data pulse of the same polarity, but invert the timing pulse and the data pulse of opposite polarities.

Abstract: A static mixer created using an additive process is disclosed. The static mixer is enabled to homogenously blend two fluids flowing in a pipe. The static mixer exhibits zero contact angle in relation to the two fluids being mixed within the pipe. The static mixer exhibits a first contact angle with the first fluid and a second contact angle with the second fluid. The first contact angle is either between 0 and 30 or greater than 85. The second contact angle is either between 0 and 30, or greater than 85.

Abstract: A system includes a determination module and a communication module. The determination module is configured to be located onboard a first vehicle that travels along a first route including a crossing corresponding to an intersection of the first route with a second route. The determination module is configured to be communicatively coupled with a remote crossing module that is configured to impede travel of a second vehicle through the crossing, and to identify an upcoming stop at a station within a range of a track detection system associated with the remote crossing module. The communication module is configured to communicatively couple the determination module to the remote crossing module, and to transmit an inhibit request message to the remote crossing module. The inhibit request message is configured to prevent the remote crossing module from activating a warning when the first vehicle is stopped at the station.

Abstract: A power distribution system among a set of units (e.g., server blocks) may comprise, for each unit, a utility line and a unit generator, and a reserve generator providing failover transient performance and redundancy improvement to the power for the unit generators. The reserve generator may connect to the units via a reserve bus, and the unit generators may selectively connect to a wraparound bus connected to the reserve bus. When the failover load exceeds the available failover transient capability of one generator, one or more unit generators may (automatically or by operator selection) be connected with the wraparound bus to apply available transient capability to satisfy the excess failover load with minimal increase in power distribution resources and complexity.
