Abstract: Embodiments disclosed herein include playback devices with multiple radios, antennas, filters, and switching circuits employed to enable switching of radios between multiple wireless networks. The switching is based on parameters of the wireless networks and on capabilities of other satellite playback devices communicating over the wireless networks. In some embodiments, the wireless networks are WIFI networks operating over one or more of a 2.4 GHz WIFI band, a lower frequency region of a 5 GHz WIFI band, a higher frequency region of the 5 GHz WIFI band, and a 6 GHz WIFI band. In some embodiments, the radios are switched between wireless networks in response to a change of frequency of a WIFI Access Point and/or a lost connection to a satellite playback device.

Abstract: A coating system for coating a strip, for example a steel strip, with a material present in the gas phase includes a coating chamber, a device for vapor deposition of the material, and a strip positioning assembly for correcting the strip transport. The strip positioning assembly has a first guide roller and a second guide roller pivoting about a pivot point, which can be effected with an adjustment unit. A method for coating a strip is also provided.

Abstract: Embodiments disclosed herein include playback devices with multiple antennas and a switching control circuit. The switching control circuit provides capabilities to enable selective switching between communication ports of a wireless radio and all possible combinations of available antennas to provide improved opportunity for achieving signal diversity. In some embodiments, the wireless radio is configured to generate a first control signal at a first rate for control of the switching circuit to select one or more antennas from a subset of the available antennas for coupling to at least one of the communication ports. In some embodiments, a processor is configured to generate a second control signal at a second rate for control of the switching circuit to select the subset of the antennas.

Abstract: A coating device includes a vacuum chamber, a crucible, at least one spray head for preparing the coating material, and an injector tube, wherein the injector tube is designed to conduct the prepared coating material to the crucible and is connected to the crucible, wherein the at least one spray head can be moved between an operating position, in which the spray head supplies the injector tube with the prepared coating material, and a removal position, and wherein at least one removal chamberis provided which is designed to be accessible from outside the vacuum chamber and which can be sealed off from the vacuum chamber and in which the at least one spray headin its removal position is separated from the vacuum chamber in a gas-tight manner.

Abstract: A method and a device for coating may involve continuously supplying a precursor, in some cases at a constant precursor level, to a plurality of coating modules. As a result, a continuous coating operation is ensured. Moreover, one such method for supplying a precursor to a plurality of coating modules of a coating device may be employed where, for example, the coating modules have a pick-off device and a supply line, the supply line which may be configured as a riser at least in some regions. Precursor may be supplied by the supply line to the pick-off device of the coating module.

Abstract: A process may be employed to produce a composite material having at least one metallic substrate and at least one polymer layer. The process may comprise applying an adhesion promoter layer across a surface of the metallic substrate and/or the polymer layer by means of plasma coating by a plasma coating system. The adhesion promoter layer may be created by driving the plasma coating system during the plasma coating such that a specific profile of the adhesion promoter layer across the surface of the metallic substrate and/or the polymer layer is established at least in some regions. The process may also involve bonding the polymer layer to the surface of the metallic substrate having the adhesion promoter layer and/or bonding the metallic substrate to the surface of the polymer layer having the adhesion promoter layer to produce the composite material.
