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.
Claims20
A method for a device, the method comprising:
- receiving, via a wireless power receiver, wireless power from one or more external transmitter devices;
- and
- based on the received wireless power, modulating operation of the device, wherein modulating operation of the device comprises transitioning the device from an active state into a low-power state according to a schedule, and wherein the schedule includes staggered periods of low-power states for a plurality of devices, such that at any given time at least one device of the plurality of devices is in an active state.
A device comprising:
- a wireless power receiver;
- one or more processors;
- and
- data storage having instructions stored thereon that, when executed by the one or more processors, cause the device to perform operations comprising:
- receiving, via the wireless power receiver, wireless power from one or more external transmitter devices;
- and
- based on the received wireless power, modulating operation of the device, wherein modulating operation of the device comprises transitioning the device from an active state into a low-power state according to a schedule, and wherein the schedule includes staggered periods of low-power states for a plurality of devices, such that at any given time at least one device of the plurality of devices is in an active state.
One or more tangible, non-transitory computer-readable media storing instructions that, when executed by one or more processors of a device, cause the device to perform operations comprising:
- receiving, via a wireless power receiver, wireless power from one or more external transmitter devices;
- and
- based on the received wireless power, modulating operation of the device, wherein modulating operation of the device comprises transitioning the device from an active state into a low-power state according to a schedule, and wherein the schedule includes staggered periods of low-power states for a plurality of devices, such that at any given time at least one device of the plurality of devices is in an active state.
