A platform exercise apparatus includes a planar platform adapted for use on a floor and elevated therefrom with an elevating portion. The ear wax guard is characterized in that, in order to improve its securing in the sound channel, it is provided with elevations at least in a subarea of its surface. This information is sufficient for the computer system to receive and process the data message, thereby providing a highly scalable low latency receiving mechanism. The folding platform may be used, along with handrails and a ladder, for accessing the platform for servicing the implement.
