A solar cell assembly including a plurality of solar cells is formed on a common substrate, and a DC/DC converter which converts the output from the solar cell is connected to each solar cell to constitute a solar power generation apparatus. The output from the solar power generation apparatus is converted into an AC power by an inverter and supplied to a load or commercial AC power system. Since the arrangement is simplified, the manufacturing cost can be reduced, and the influence of partial shade or a variation in characteristic decreases.

A method for fabricating a silicon oxide/silicon nitride/silicon oxide stacked layer structure is described. A bottom oxide layer is formed over a substrate.

A system monitors and characterizes internal elasticity of a blood vessel to detect abnormality. A catheter system for heart performance characterization and abnormality detection, comprises an ultrasound device for emitting ultrasound wave signals within patient anatomy and acquiring corresponding ultrasound echo signals. A signal processor processes the ultrasound echo signals to, determine a signal indicating displacement of a tissue wall over at least one heart cycle and identify a displacement value in the displacement signal. The displacement value indicates a tissue wall displacement occurring at a point within a heart cycle. A comparator compares the tissue wall displacement value with a threshold value to provide a comparison indicator. A patient monitor, in response to the comparison indicator indicating the tissue wall displacement value exceeds the threshold value, generates an alert message associated with the threshold.

The present invention enables permanent biometric authentication without the risk of forgery or the like. The present invention enables living-tissue discrimination as well as biometric authentication. The roughness distribution pattern of deep-layer tissue of the skin covered with epidermal tissue is detected, thereby extracting a unique pattern of the living tissue. Then, biometric authentication is performed based upon the detected pattern. The roughness distribution pattern of the deep-layer tissue of the skin is optically detected using difference in optical properties between the epidermal tissue and the deep-layer tissue of the skin. In this case, long-wavelength light, e.g., near-infrared light is used as illumination light cast onto the skin tissue. A fork structure of a subcutaneous blood vessel is used as the portion which is to be detected, for example. The portion which is to be detected is determined based upon the structure of the fork structure. In this case, the living-tissue discrimination may be made using the subcutaneous blood vessel.
