Abstract: Examples described herein relate to transitioning a playback session between portable playback devices such as “smart” headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).

Abstract: Disclosed herein are devices (e.g., audio playback devices) configured to transmit and/or receive wireless power. Wireless power can be transferred using mid-range or long-range techniques, such as electromagnetic radiation (e.g., lasers, microwaves) or electromagnetic coupling (e.g., inductive coupling, capacitive coupling). Device performance and/or power transmission may be modified dynamically based on wireless power levels, user behavior, the behavior of other devices, device grouping, or other parameters.

Abstract: The present disclosure provides methods for forming flow plate and frame assemblies that comprise an anode frame member, a flow plate, and cathode frame member with the flow plate retained between the anode and cathode frame members. The present disclosure also provides for flow plate and frame assemblies, fuel cell stacks containing a plurality of the flow plate and frame assemblies, and fuel cell systems containing the fuel cell stacks. A fluidly connected anode fluid pathway can be provided from an anode fluid inlet, through conduits int eh anode frame member, onto an anode surface of the flow plate, and into anode flow channels.

Abstract: Systems and methods for providing spatial audio are disclosed herein. In one example, the method includes receiving a first position of a first playback device relative to a user in a listening environment; receiving a second position of a second playback device relative to the user in the listening environment; transmitting, to a media content provider, location data corresponding to the first and second positions; receiving, from the media content provider, virtual media audio content associated with a virtual environment, the virtual media audio content comprising first and second audio signals generated based on the transmitted location data, wherein the generated first and second audio signals include one or more audio cues configured to enable the user to spatially perceive a location of a virtual object within the listening environment; and playing back the first audio signal via the first playback device in synchrony with playing back the second audio signal via the second playback device.

Abstract: Example techniques described herein involve a media playback system of one or more playback devices that are operable in a plurality of modes. Operating in a given mode may enhance a use case corresponding to the mode. For instance, the plurality of modes may include a foreground mode, which may enhance active listening to the playback device. The plurality of modes may also include a background mode, which may enhance passive listening to the playback device by facilitating other activities during passive listening. In some example implementations, the plurality of modes are non-contemporary; when operating in one mode, the playback device will not be operating in the other modes, and vice versa.
