Abstract: A system may include at least two coil circuit branches, a driver, and a controller. Each of the at least two coil circuit branches may include a coil and a switch. The at least two coil circuit branches may be connected in parallel. The driver may be connected to the at least two coil circuit branches that are connected in parallel. The driver may be configured to drive the coils in the at least two coil circuit branches. The controller may be configured to independently control the switch in each of the at least two coil circuit branches to independently control whether the driver is electrically connected to drive the coil in the corresponding coil circuit branch. Some system embodiments include a dedicated driver for each of the coil circuit branches, and a controller configured to independently control the drivers to independently control whether individual coils are driven.

Abstract: The present invention is a face mask suitable for application to a skin surface of a person's face, the face mask comprising a plurality of facial mask segments of resilient polymeric foam, each segment conformable to at least a portion of the surface of the person's face and including a first surface, a second surface and a shaped peripheral margin, an adhesive attachment, suitable for use on the first surface of each segment and suitable for attaching the segment to the person's skin; and a decoration, suitable for application on the second surface of each segment, for decorating the face mask; wherein the plurality of facial mask segments cover substantially all of the surface of the skin of the person's face.
