The invention refers to a mounting system for attachment of a bumper covering at a motor vehicle body which includes a mounting strip, a guide profile and a locking slider which in mounted condition provides connection between the mounting strip and the guide profile, wherein at least the guide profile is configured as a separate component. In one embodiment a D scale multiresolution sampler, filter bank router, filter bank sampler controller, phase shifter, and consolidator constitute a maximal arrangement for a D scale FIRIIR filter design. Periodically, the monitor analyzes the histogram data to determine heart rate dependent acute ischemia detection thresholds. The light-shielding layers are formed by weaving light-shielding layer wrap threads and the weft threads, and the light-shielding layers are sequentially and repeatedly connected to front layer-connecting parts and rear layer-connecting parts. A saw blade, attached to a front end of the plunger, causes an orbital motion according to a phase difference between two eccentric shaft portions regardless of attached direction of the saw blade. More specifically, it provides an – compound represented by the following formula, a pharmacologically acceptable salt thereof or a hydrate thereof: In the formula, R1, R2, R3 and R4 are the same as or different from each other.
