The present invention relates to the method of increasing the bioavailability of Angiotensin II Receptor Blockers by preparing a composition of an ARB with at least one solubility enhancing agent. A probe card in a testing apparatus includes probes for Kelvin contact, the probes for Kelvin contact including a coil probe and a POGO pin probe disposed inside the coil probe, and a probe for two-terminal measurement. A bi-directional modifier is stored in distinct tables and comprises arbitrary text strings defined by user input. A gate electrode layer is formed to oppose to the sidewall of n cathode region with insulating film interposed. Further, at least two wireless gateway devices are each respectively operated by the end users, and the wireless gateway devices are configured to provide wireless access to the communication network within a transmission range and to communicate with the at one least information processor.
