A system and method are disclosed for improving a statistical message classifier. More specifically, the method includes the MS which receives status information of a first channel descriptor and transmission frame information which includes when the first channel descriptor is to be transmitted. The sensor generates a sensor signal in response to the windshield section imaged thereon. Eddy current thus does not increase at an inner rim of the stator, where magnetic flux intensely changes. Medicinal products containing the same which are useful as DPP-IV inhibitors.
