Xyloband
Xylobands are wristbands that contain light-emitting diodes and radio frequency receivers, they were launched by RB Concepts Ltd, a company set up by entrepreneur Clive Banks with inventor Jason Regler. The lights inside the wristband can be controlled by a software program, which sends signals to the wristband, instructing it to light up or blink, for example. The RGB version has a white strap and can emit any colour on the visible spectrum. The single colour version is available in green, blue, yellow, red, pink, and white. The first use of Xylobands on a large scale was on  Coldplay's 2012 Mylo Xyloto tour. A Xyloband was given to each member of the audience, and as the concert played, the flashing of the wristbands was synchronized to the music. The inventor of the wristbands, Jason Regler, stated that he had the idea for the product while at a Coldplay concert, during the song "Fix You". Technology. The wristbands themselves are constructed of a thick fabric with LEDs inside the fabric. A radio receiver is located within a plastic case on the band, and it receives wireless signals from a controller. These signals are sent either by a handheld  TV remote styled controller, which has a range of 250 meters, or a controller which is hosted on a laptop computer linked to a radio transmitter, which can remotely control the wristbands from up to 300 meters away. The operator of the controller or laptop software may program all wristbands or only those of certain colors to flash on and off at specific intervals and specific moments. The wristbands are not intended to be lit outside of the concert venue, although there exist anecdotes of Xylobands "coming back to life" at seemingly random times. Uses. The wristbands were given to  each audience member at Coldplay's 2012 Mylo Xyloto tour.

It is uncertain whether or not Xylobands will be used by other organizations, such as sports teams. Regler and Coldplay currently have an agreement which governs the design trademark on the wristbands, the patent, and the intellectual property rights to the Xylobands. Regler also  stated that the band would not want the Xyloband experience diluted, and that it remained to be seen if they would be marketed to other organizations. Yet, Xylobands' website beckons prospective customers to "put your brand on a Xyloband!"
