Information derived from ECG signals and EEG signals may be employed in combination to reliably predict the onset, or to indicate the presence of, hypoglycemia in a human patient. The liquid crystal alignment solution includes a first polyimide-polyamide acid and a second polyimide-polyamide acid. The UE may also receive a data transmission associated with the PDCCH on a physical downlink shared channel on a second CC. A color signal replacement unit is configured to replace a signal of a pixel corresponding to the detection level with a predetermined color signal when the detection level satisfies a predetermined condition. There is also provided a sensor system front-end and a relaxation oscillator.
