The communication channels include CMDA channels, WCDMA, GSM channels, GPRS channels, and EDGE channels.

The vertical channels include two nested channels wherein the two vertical channels face each other.

At first the heating channels resp. collecting channels are bored.

The exhaust channels are placed in communication with the arc channels.

The channel surfaces that define the membrane channels are membrane-channel surfaces.

In some embodiments, the compounds are more selective for certain potassium channels (e.g., Kv1.3 channels) than other potassium channels (e.g., Kv1.5 channels).

Channel capping elements at least partially close the air channels.

The reaction channels and the heat-exchange channels are arranged such that individual reaction channels are in thermal communication with individual heat-exchange channels.

If the first m channels are occupied, the next channels are scanned.

Preferably the channels of the device are capillary channels.

A substantial portion of the channels are interconnected to other channels.

In respect of the KATP channels the potassium channel blocker may blocks channels with SUR2B subunits e.g. channels with SUR2B and Kir6.1 subunits.

The measurable channels, designated probe channels, may be channels for use in a digital system.

The channel forming laminate layers define a network of fluid flow channels.

The vent channels are configured for the fluid to flow through the vent channels.
