Abstract: A method for observation and/or operation of a sport and/or rehabilitation device uses open-loop and/or closed-loop control of the device. A smartphone, navigation device, digital picture frames or a tablet PC is used as the Human Machine Interface (HMI). The HMI and the sport and/or rehabilitation device connect to one another via a communication connection. The HMI and the sport and/or rehabilitation device identify each other mutually. The sport and/or rehabilitation device checks the HMI for its suitability for observation and/or operation. In the event of the HMI being suitable for observation and/or operation of the sport and/or rehabilitation device, an application is started at the HMI for observation and/or operation of the sport and/or rehabilitation device. In the event of the HMI not being suitable for observation and/or operation of the sport and/or rehabilitation device, a signal is output.

Abstract: A lighting unit includes a transparent carrier panel provided with electrically conductive structures, in particular a structured ITO layer on one side. Surface mount LEDs having terminals on both sides of a light emitting side are mounted on the carrier panel in such a way that the terminals are in contact with the conductive structures. The light emitting side faces the carrier panel.
