A system includes a safety helmet and an earpiece, wherein the earpiece is configured to determine when a user of the earpiece is wearing the safety helmet. The earpiece may include a touch surface and at least one sensor associated with the touch surface and wherein the earpiece is configured to ignore input at the touch surface when the user of the earpiece is wearing the safety helmet. A method includes sensing by an earpiece that a user is wearing a helmet and deactivating sensors associated with a touch input area on the ear piece when the user is wearing the helmet. A method includes charging an earpiece using a battery of a helmet while a user is wearing the earpiece and the helmet. A method includes communicating data from one or more sensors of a helmet or one or more sensors of a motorcycle to an earpiece and providing audio output indicating of the data to a user through a speaker of the earpiece.

Wearable electronic device includes a neck loop worn on a neck with two electromechanical units; two in-ear earphones; two earphone cords. Each unit has an earphone cord winding mechanism including (i) a spool for winding the earphone cord; (ii) a double drive mechanism including an electric motor, a reducer, and a spiral spring; (iii) an engagement mechanism for engagement between the drive mechanism and the spool; and (iv) a lock mechanism. One unit has a motor control key for the electric motor and the lock mechanism. One end of the cords is connected to one of the earphones and the other end to one of the spools. The units are mechanically connected to each other to prevent twisting, and to the neck loop so that one of the units is on the left side of the chest, and the other electromechanical unit is on the right side of the chest.

This document describes techniques and devices for detecting twist input with an interactive cord. An interactive cord may be constructed with one or more conductive yarns wrapped around a cable in a first direction (e.g., clockwise), and one or more conductive yarns wrapped around the cable in a second direction that is opposite the first direction (e.g., counter-clockwise). A controller measures one or more capacitance values associated with the conductive yarns. In response to detecting a change in the one or more capacitance values, the controller determines that the change in the capacitance values corresponds to twist input caused by the user twisting the interactive cord. Then, the controller initiates one or more functions based on the twist input, such as by controlling audio to a headset by increasing or decreasing the volume, scrolling through menu items, and so forth.

A user device that can be touched by a user includes a heat source that can generate heat; a case body covering the heat source; and a polymer-containing heat storage body attached to the case body.
