In order to increase the capacity of a deployed passive optical network without replacing optical network terminators, a PON is provided that is partitioned into multiple channels. The six-axis positioner has a gantry and a wrist. The chemical modifications andor ligand additions provide additional characteristics to the compositions without interfering substantially with their biological function. The sleeve compresses and lengthens in a forward direction ultimately enveloping the plunger distal tip. Each of the plurality of couplings is connected to an associated one of the plurality of connectors. The device includes an activity monitor configured to infer a user touch to the shell in response to a detected activity of the portable electronic device.
