Abstract: A removable communication device is described herein. The removable communication device is configured to communicatively couple to a variety of receiving devices via a physical and/or electrical connection. When coupled the removable communication device can control the variety of receiving devices at least in part by using a touchscreen user interface located on the removable communication device.

Abstract: The technology described in this document can be embodied in a method that includes receiving a first signal representative of audio captured using a microphone in communication with an analog communication module. The method also includes determining that a first feedback signal from the analog communication module includes a sidetone associated with the audio captured by the microphone, and responsive to determining that the first feedback signal includes the sidetone, generating, by one or more processing devices, at least one control signal that affects operations of a digital communication module.

Abstract: A method of customizing the fit of a portion of an in-ear audio device within a portion of an ear includes determining a degree of sealing between the in-ear audio device and the portion of the ear and applying a voltage to at least a portion of an ear tip coupled to the in-ear audio device to selectively expand or contract the portion of the ear tip based on the determination until the degree of sealing between the in-ear audio device and the portion of the ear achieves a desired degree of sealing.

Abstract: A recognition system includes a camera, at least one speaker, a microphone, and a processor in communication with the camera, the speaker, and the microphone. The processor is configured to recognize faces or devices and to receive a selection of at least one face or device to be monitored. The processor is also configured to direct the camera and/or the microphone toward the selected face or device and provide audio from the selected face or device to the speaker.
