A device, system and method for capturing in-vivo images allows for size or distance estimations for objects within the images. In pulse oximetry, the signals measured at different wavelengths represent the mixture signals, while the plethysmographic signal, motion artifact, respiratory artifact and instrumental noise represent the source components. The cooling fluid floods the stator, rotor, andor bearings to cool the components. Since this system does not depend on an optically precise entry surface, it may be useful in fiber optic and solar power applications. The oriented films generally include a propylene based polymer and an additive selected from fluoropolymers, fluoroelastomers and combinations thereof, wherein the additive is present in an amount of from about 50 ppm to about 20,000 ppm. The passivation layer and the underlying layers are etched through the photoresist pattern to form a semiconductor pattern and contact windows.
