The present invention relates to a process for the preparation of arsenic free water and an apparatus therefor. After an initial interaction between the probe and the sensing-recording device, the sensing-recording device samples one or more physiological parameters and stores time stamped readings in a first memory. The upper toe sole area is linked to the lower toe sole area by linkages that hold the upper toe sole area is held parallel to the lower toe sole area. The three-dimensional mesh is preferably molded into the tissue tack. In a non-light-emitting period, the scanning line driving circuit sets, during a period from a start of a reset period to an end of the non-light-emitting period, a fixed voltage corresponding to the potential of the negative power source line to the source electrode of the driving transistor.
