An apparatus for use in the treatment of substrates with a solid particulate material, said apparatus comprising: (a) a housing having mounted therein a rotatably mounted drum (8) having an inner surface and an end wall; and (b) access means for introducing said substrates into said drum, wherein said drum comprises storage means (2) for storage of said solid particulate material and a plurality of flow paths to facilitate flow of said solid particulate material between said storage means and the interior of said drum (8), characterised in that: said drum (8) comprises a dispensing flow path (5) to facilitate flow of said solid particulate material from said storage means (2) to the interior of said drum (8), and a collecting flow path (6) to facilitate flow of said particulate material from the interior of said drum (8) to said storage means (2), wherein said dispensing flow path (5) and said collecting flow path (6) are different flow paths.

A sensor device is provided. The sensor device includes an energy harvester configured to generate electric energy, a monitoring circuit, a sensor, a communication circuit, and at least one processor configured to obtain information indicating a magnitude of the generated electric energy via the monitoring circuit, obtain a sensing value via the sensor, and transmit the sensing value and the information indicating the magnitude of the generated electric energy via the communication circuit to the other electronic device.

An induction dryer appliance includes a cabinet. A drum is positioned within the cabinet. The drum is rotatable about an axis within the cabinet. The induction dryer appliance also includes an induction heating element and a support assembly. The support assembly is positioned within the cabinet adjacent the drum. The support assembly includes a plate. The induction heating element is positioned on the plate. A bearing is mounted to the plate. The bearing contacts the drum as the drum rotates about the axis such that the bearing spaces the plate from the drum along a radial direction that is perpendicular to the axis.
