Abstract: Embodiments provide a method for determining an alternating magnetic field (AMF) transmitter design that produces a magnetic field that achieves a more uniform surface current or heating of an implant. Embodiments may utilize the method to be applicable to different geometries of implants and AMF transmitters. Embodiments produce a non-uniform magnetic field that in turn produces a more uniform current density/distribution on the implant surface. This leads to uniform heating and consistent biofilm reduction, while minimizing damage to adjacent tissues. Also, the differences in electrical properties such as conductivity, permittivity, and permeability of the implant components can be factored into the design process to achieve a uniform current density/distribution across components. An ultimate benefit derived from embodiments described herein is consistent biofilm reduction, inactivation, eradication, destruction, and/or removal and improved safety arising from heat conduction into surrounding tissues.

Abstract: A central vacuum power unit includes separate components that can be disassembled and nested together for compact shipment and storage. In the disassembled and nested assembly, the motor module is nested within the dust bucket, and the dust bucket is nested within the body module. For vacuuming operation, the dust bucket is attached below the body module and the motor module is stacked and attached above the body module. A filter is disposed inside the body module and filters debris from air entering the power unit. Debris is collected in the dust bucket, and filtered air is exhausted from a port in the motor module. Latches on the body module are used to attach the dust bucket underneath the body module in operation, and to secure the nested assembly for packaging and shipping.
