Abstract: Methods and systems for acoustically treating material are described. Acoustic energy is emitted into a waveguide having a wall with a shape that tapers away from the acoustic source. The wall may have a substantially conical or parabolic shape. When emitted therein, the waveguide causes convergence of the acoustic energy so as to form an acoustic focal zone at a vessel. In some embodiments, a substantial portion of the acoustic focal zone is located outside of the internal volume defined by the waveguide.

Abstract: Methods and systems for treating material with focused acoustic energy and/or ultraviolet radiation are described. Sample material may be provided to a single batch vessel or may flow in a continuous or intermittent fashion into/out of a processing chamber within which the material is exposed to focused acoustic energy and/or ultraviolet radiation. Exposure to focused acoustics in a flow through environment may enhance the effects of the radiation on the sample material. Further, in flow-through or single batch arrangements, sample material may be retained exterior to or within a processing chamber by one or more retaining members (e.g., filter, valve, etc.) until a characteristic of the sample material reaches one or more particular criteria (e.g., physical, chemical, biological). Once the criteria of the sample material is attained (e.g., via further treatment), the material is then permitted to flow past the retaining member(s) and through the inlet or outlet of the chamber.

The one or more intermediate modes activate interference management processes and the wireless device transmits data and receives data simultaneously. In some embodiments, transmission interference may be based on an SINR measurement.

Abstract: Methods and systems for acoustically treating material using an acoustic energy system having a movable outer surface that contacts a sample holder. The outer surface may be cylindrical and rotate about a central axis, e.g., so that a sample holder may be driven to move by the outer surface. Acoustic energy may be emitted from within the outer surface to a treatment area outside of, and near, the outer surface. Thus, a sample holder in contact with the outer surface may have a sample exposed to acoustic energy while rotation of the outer surface may move the sample holder relative to treatment area. One or more additional rollers or other components may bias the sample holder into contact with the outer surface, to e.g., so the sample holder is squeezed between the outer surface and a roller or other biasing component.
