A device and method for enriching andor depleting substances in a liquid is disclosed. A maximumminimum extraction circuit outputs, as a maximum current, a current having a maximum current value among currents supplied thereto from lamp drive circuits and outputs, as a minimum current, a current having a minimum current value. Such sweat-diverting devices may comprise a first leg and a second leg that are joined at a base of the device to form a channel therebetween, where at least a portion of the base is more rigid than the first and second legs such that an acute angle between the first and second legs is maintained when the sweat-diverting device is applied on a wearer’s forehead. Because the scaled physical capacity is greater than the NVM’s actual physical capacity, the file system allocates a logical space to the NVM that is substantially greater than the NVM’s capacity. A second or activation arm of the terminal clip extends from an opposite end of the barrel segment and crosses over the first arm so that compression of the arms toward one-another causes the loop segment to enlarge for receipt of the ground stud. The machine further comprises at least one built-in packaging station for packaging groups of the articles in bag-like packets.
