Abstract: An adjustable leakage inductance transformer includes a magnetic core, a primary side coil and a secondary side coil. The magnetic core includes a magnetic core column structure, which has a central column, a first outer column and a second outer column. The primary side coil is wound on the first outer column and the second outer column by a first primary side coil loop number and a second primary side coil loop number, respectively. The secondary side coil is wound on the first outer column and the second outer column by a first secondary side coil loop number and a second secondary side coil loop number, respectively, the first primary side coil loop number is not equal to the first secondary side coil loop number, and the second primary side coil loop number is not equal to the second secondary side coil loop number.

Abstract: A method of manufacturing a three-dimensional article includes: (1) Loading a metal platen into a build chamber, the metal platen defines an upper surface; (2) Performing concurrent processes including operating a movement mechanism to vertically translate the platen, operating a laser system to impinge a radiation beam upon the upper surface of the platen, and receiving a signal from an acoustic sensor that is positioned within the build chamber; (3) Analyzing the signal including determining a height of optimal laser convergence for the platen; and (4) Based upon the analysis, adjusting the laser convergence height to a build plane height.

Abstract: Methods and systems for enforcing host standards in a reservation system. In one embodiment, a reservation system provides two methods of communication between a potential guest and a host, hard communications and soft communications. The reservation system associates both types of communication with threads, each thread associated with the host and an associated reservation. The reservation system determines suspension metrics for each host based on the communications of the threads they are associated with. When the suspension metrics associated with a host satisfy one or more suspension criteria, the reservation system issues a suspension to the host.

Abstract: A pneumatic tire assembly is provided and includes an annular tire, an annular inflatable inner tube, and an annular solid insulation tube. The annular inflatable inner tube is positioned within the annular tire. The annular solid insulation tube is positioned between the annular tire and the annular inflatable inner tube and includes an outer surface in contact with an inner surface of the annular tire and an inner surface in contact with an outer surface of the annular inflatable inner tube.
