Abstract: Example implementations described herein are directed to implementation of the atomic write feature in the storage system setting. Example implementations may utilize flash memory to facilitate or to form atomic write commands to improve flash memory performance and endurance. Several protocols involving the cache unit of the storage system may include managing a status of the storage system so that data corresponding to an atomic write command are stored in a cache unit, with old data maintained in the storage system until the write data corresponding to an atomic write command is properly received.

Abstract: A biological information detection apparatus includes: a camera; a frame image analysis unit that detects a region including pixels having a predetermined skin color, as a skin color region, from a frame image taken using the camera, and detects a signal corresponding to a light wavelength from an image signal of each pixel included in the skin color region, as skin color wavelength data; a skin color wavelength difference detection unit that calculates an average value of differences of the skin color wavelength data from predetermined reference wavelength data for the pixels included in the skin color region, and acquires the average value as average wavelength difference data; a pulse wave signal detection unit that detects a signal obtained by smoothing the average wavelength difference data detected in time series, as a pulse wave signal.
