The present invention relates to imidazopyridine derivatives of the Formula I and, therapeutically acceptable salts thereof which inhibit exogenously or endogenously stimulated gastric acid secretion and thus can be used in the treatment of gastrointestinal inflammatory diseases. The system includes a lateral acceleration sensor for determining the lateral acceleration of the vehicle, a steering angle sensor for determining the steering angle of the vehicle and a speed sensor for determining the speed of the vehicle. The phase detecting unit detects the phase of the AC power supply on the basis of the AC signal from the signal processing unit when power is recovered from the power outage. 44 \u03bcm, and the width of a second Cu wiring and the diameter of a plug are about 0. The mobile radio equipment includes: a security-level selection unit that selects one from among a plurality of security levels; and an encryptiondecryption unit that encryptsdecrypts data tofrom the radio control system using confidentiality parameters that are notified from the radio control system and correspond to the security level chosen by the security-level selection unit. The method may be performed in vivo.
