A diplex Doppler type radar system which can detect a preceding vehicle even when the range rate of a preceding vehicle relative to a vehicle having the radar system is small. The ceramic tibial component is provided in the form of a ceramic monoblock adapted for fixation relative to the patient’s tibial bone, or alternately in the form of a ceramic bearing insert component carried by a tibial baseplate member which is adapted in turn for fixation relative to tibial bone. The segmented polymers are functionalized and are useful for conjugation to various moieties such as pharmacologically active substances. Estimated battery OCV is related to estimated battery SOC by a nonlinear mapping. A probability estimation table from a QM arithmetic coder allows the R-D slope to be derived using a lookup table operation. The apparatus includes means for recognizing a disc or chip in the microfludic system, performs an operation and detection by automatically loading a DB according to a recognized type, and perform quantization of a test.
