Abstract: Systems, methods, and non-transitory computer-readable storage media for performing a role swapping operation between a pair of non-tethered wireless ear buds after detecting a triggering event. Further, state information can be coordinated between devices, including in connection with performing a role swap between buds in a pair of wireless, untethered ear buds, where one wireless ear bud is in a primary role and is responsible for a connection with a companion device, and another wireless ear bud in the pair is in a secondary role.

Abstract: A method and apparatus is disclosed for laying a drawthread into a machine knitted fabric. Before it is laid the drawthread is carried from between one side and another of the yarns which are being knitted to form the fabric by a component which passes between yarn guides of the machine. The component may be permanently located between the yarn guides or may pass between the yarn guides and out again between two stitch forming cycles of the machine. On both sides the drawthread is positioned by the said component clear of the area where stitches are formed so that it is not knitted into the fabric.
