A water treatment cartridge, or insert, for use in connection with a water treatment device such as a gravity-fed water pitcher or the like includes a support structure and water treatment material arranged in combination with the support structure. The housing further has a monolithically formed flange portion extending orthogonally therefrom. In this embodiment the metal foil is encapsulated by the adhesive layers. According to one embodiment, at least one sublithographic gap is a slit or line that traverses the width of the gate conductor structure. The lifters lift the jumper higher, support the jumper in the jump while the jumper attempts to intercept a ball, and safely lower the jumper. This effectively merges the N IGP instances at each node so that the multi-ring network appears as a virtual single-ring network with a single IGP instance allowing each of the receivers access to any source connected to the network.
