Abstract: A voice-controlled electronic device that includes a device housing having a longitudinal axis bisecting opposing top and bottom surfaces and a side surface extending between the top and bottom surfaces. The device can further include one or more microphones disposed within the device housing and distributed radially around the longitudinal axis; a processor configured to execute computer instructions stored in a computer-readable memory for interacting with a user and processing voice commands received by the one or more microphones and first transducer and second transducers configured to generate sound waves within different frequency ranges.

Abstract: Tubular structures, for example pipes, are coated at least in an interior thereof with a nickel containing coating via at least one distribution manifold with ports which are received in the interior of the tubular structure. An electroless nickel coating solution may be pumped or supplied via gravity feed to the distribution manifold. The tubular structure may concurrently be immersed in electroless nickel coating solution in a tank. A second distribution manifold may deliver electroless nickel coating solution to the interior of the tubular structure in an opposite direction from the first. The two distribution manifolds may be used as part of a support structure to lift or move the tubular structure. Additional tanks may hold other solutions, for instance cleaning solutions, etching solutions and rinses.
