Abstract: Systems including a right true wireless earbud, a left true wireless earbud, and eyeglasses are disclosed. Eyeglasses may include a left temple having a feature configured to selectively couple with the left true wireless earbud, and a right temple having a feature configured to selectively couple with the right true wireless earbud. For some eyeglasses, a left accessory arm may be coupled to the left temple, the left accessory arm configured to couple with a left true wireless earbud, and a right accessory arm may be coupled to the right temple, the right accessory arm configured to couple with a right true wireless earbud. For additional eyeglasses, a left storage compartment may be located in the left temple sized and configured to couple with a left true wireless earbud, and a right storage compartment located in the right temple sized and configured to couple with a right true wireless earbud.

Abstract: Devices, methods, systems, and computer-readable media for a tunable diffraction grating are described herein. One or more embodiments include a tunable diffraction grating having an electromagnetic array and a ferrofluid positioned proximate to the electromagnetic array and positioned to receive and reflect a beam of radiation.

Abstract: A wireless earbud system includes a first earbud assembly and a second earbud assembly. Each of the first earbud assembly and the second earbud assembly include a housing, an audio driver disposed within the housing, and a wireless receiving unit operatively coupled to the audio driver. The wireless receiving unit is configured to receive a wireless data signal and drive the audio driver based on audio data transmitted in the wireless data signal. The wireless earbud system may also include a tether with a first end and a second end. The first end of the tether is configured to removably couple to the first earbud assembly by a first detachable connector, and the second end of the tether is configured to removably couple to the second earbud assembly by a second detachable connector. Methods also relate to the wireless earbud system.
