Abstract: An image sensor includes a pixel array in which pixels having photoelectric conversion elements are arranged in a matrix, color filters corresponding to the pixels and configured to selectively transmit light of at least two different wavelength bands, and microlenses on the color filters. At least some of the microlenses may have different shapes depending on respective wavelength bands that respective corresponding color filters at least partially overlapping with the at least some microlenses are configured to selectively transmit, such that the at least some microlenses are configured to compensate for chromatic aberration between the lights passing through the respective corresponding color filters.

Abstract: This invention relates to a hair braider and its auxiliary device, which are portable and braids three bunches of hair into a strand. The hair braider has a substantially figure ‘8’-configured cam track allowing three carriers to move along the cam track for a ‘8’ track motion. Three carriers combined detachably with three grabbing members accommodating three bunches of hair therein travels along the cam track as a couple of rotors rotate in opposite direction. While three hair grabbing member held on the holders of the carriers conduct the figure ‘8’ motion, three bunches of hair in three hair grabbing members are braided into one strand.

Abstract: The present invention provides an apparatus and method which contains a particular date preset by a user and several groups of particular information, each group relating to a pre-specified date difference between the preset date and current date, and automatically displays a group of information corresponding to current date difference. The apparatus according to the present invention comprises a nonvolatile memory for storing information corresponding to date differences, a timing unit for tracking current time and date, a control unit for calculating the date difference between the preset date and current date and reading out information depending upon the date difference from the memory, a ROM storing an execution program, a font ROM storing display fonts, a LCD control unit, a LCD panel, an audio signal generation unit, and a beeper.

Abstract: The present invention provides an apparatus and method for detecting sounds from a human body and displaying the detected sound information. The apparatus comprises a stethoscope for collecting sounds, a piezoelectric device for converting the collected sounds into an electric signal, a speaker for converting the electric signal into audible sound, an A/D converter for digitizing the electric signal, a memory for storing the digitized sound data, a microprocessor for issuing the switch control signal, extracting features of the stored data, analyzing the extracted feature values statistically, storing the analyzed statistical figures in the memory, and reading out the statistical figures from the memory, and an LCD panel for displaying the LCD signals.
