The waveform of the photoplethysmographic image (PPGi) signals may be significantly affected by the light spectra and intensity. The purpose of this study is to evaluate the performance of PPGi aveform acquisition in the red, green and blue channels using a commercial camera in different light conditions. The fitted curve of PPGi amplitudes in the RGB channels with different light intensity for 470 nm, 490 nm, 505 nm, 590 nm, 600 nm, 610 nm, 625 nm, 660 nm wavelengths and white light. X-axes represent averaging DC output form pixels and y-axes represent averaging AC output form pixels. These representative data are from one male, age 30 years old.

This study evaluated an experimental procedure for providing data on the complex permittivity of different cell lines in the 2-50 GHz range at room temperature, for the purpose of future dosimetric studies. The complex permittivity measurements were performed on cells suspended in culture medium using an open-ended coaxial probe. The results demonstrate the method to be a viable technique for distinguishing between different cancerous and non-cancerous cell types. Other possible clinical applications include optimizing exposure frequency for hyperthermia treatment.

Panel B shows 12 minutes of bipolar EEG from Fp2-F4 (1-70 Hz, 200 S/s). Panel A is the corresponding spectrogram. Panel E shows 30 seconds of EEG from Panel B at the onset of the generalized seizure (dashed line). Panels C, D, and F are the corresponding tEEG signals from Fp2’ (1-100 Hz, 200 S/s). Note the high gamma-band burst HFOs just prior to the partial seizure (highlighted by ellipse in panel C).
