A fuel injection system having a high-pressure fuel pump and a fuel injection valve for each engine cylinder. Embodiments of the invention further provide a MRI imaging suite and a method for distension of a body part to be imaged. An allocator allocates the quantization error correction component calculated by the subtracter to a plurality of the pixels around the target pixel. The temperature-induced wavelength drift of a transmission spectrometer can be due to the frame upon which the transmission grating is mounted. Practical embodiments of the POR circuit include a control circuit that reduces static andor dynamic current leakage associated with the operation of the POR circuit.
