    Abstract: A system for in situ repair of a metal pipe has a pipe repair head, an actuation assembly, an electrical power supply, and a controller. The pipe repair head can have an arm extending along a radiation direction of the pipe and a Joule heating element coupled to a distal end portion of the arm. The actuation assembly can move the pipe repair head along the axial and/or circumferential directions of the metal pipe. The controller controls the actuation assembly to position the pipe repair head with respect to a surface portion of the inner circumferential wall. The controller can then control the electrical power supply to apply a current pulse to the Joule heating element so as to generate a temperature of at least 1000° C. proximal to the surface portion, thereby sintering a metal powder in a slurry on the surface portion to form a metal repair layer.

    Abstract: There is a fixation device for promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, comprising a bone plate portion including an outer surface, an inner surface and at least one fixation aperture extending from the outer surface to the inner surface and a bone wedge portion extending from the plate portion at a first end and a free opposite end, the bone wedge portion comprising a porous architecture configured to promote bone ingrowth, the wedge portion defining first and second engagement surfaces for engaging the first bone segment and a second bone segment, respectively. There is also a method of manufacturing a fixation device for promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, a method of promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, and a fixation kit.

    Abstract: An electrodischarge apparatus has a nozzle that includes a discharge chamber that has an inlet for receiving a liquid and an outlet. The apparatus has a first electrode extending into the discharge chamber that is electrically connected to one or more high-voltage capacitors. A second electrode is proximate to the first electrode to define a gap between the first and second electrodes. A switch causes the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes from the nozzle ahead of the plasma bubble.

    Abstract: A mechanical means for deploying one of two or more feed sources within a test range is presented. The feed source selected for testing is properly positioned for use within the range by rotating one of two or more arms to an upright and locked position. An arm may further include a rotatable antenna wheel with two or more feed sources thereon whereby a selected feed source is rotated into position via the antenna wheel. The antenna wheel includes a center body, feed sources attached to the center body and aligned along a rotational plane, and a shroud disposed about the center body and feed sources. The antenna wheel may include a cooling system for managing heat generated by the feed sources and electronics therefore. In preferred embodiments, the feed source changer is mounted within the range so that a selected feed source communicates an emitted beam onto a reflector which is redirected as a reflected beam toward a device under test. Concealment panel(s) may be positioned adjacent to the feed source changer to minimize electromagnetic reflections therefrom.
