Abstract: A punching needle for a handpiece used to separate a follicle of an extraction target hair from a skin tissue of a patient while the punching needle is rotated is provided. The punching needle includes a slit formed at one side of a front end portion thereof, the slit extends rearward from the front end portion of the punching needle in a longitudinal direction of the punching needle, and the punching needle is mounted in and used in the handpiece to allow a part of the slit or the entire slit to be exposed in front of the handpiece. The punching needle enables an inside of the punching needle to be directly and visually checked through the slit and enables the extraction target hair to be inserted into the punching needle from a side of the punching needle through the slit formed in the punching needle.

Abstract: According to one embodiment of the present disclosure, a punching needle for a handpiece used to extract follicle from patient's skin is provided. According to one embodiment of the present disclosure, an accommodation space, into which follicle of extraction target hair may be inserted, may be formed in the inside of a front portion of the punching needle, and a punching portion of contacting with the patient's skin and punching the patient's skin may be provided in the front end portion of the punching needle. According to one embodiment of the present disclosure, the punching portion may comprise a first punching portion and a second punching portion which have different-shaped cutting edges, and a first cutting edge provided in the first punching portion may be formed in a shape that is sharper than that of a second cutting edge provided in the second punching portion.

Abstract: Disclosed herein is an attitude correction apparatus for an Inertial Navigation System (INS) using a camera-type solar sensor. The present invention relates to a system for correcting errors occurring in an inertial navigation system, in which inertial sensors, such as gyroscopes and accelerometers are combined with each other to calculate the attitude, velocity and position of an airplane, and to an apparatus for utilizing a sun-line of sight vector, generated by a camera-type solar sensor, that uses images of the moving sun, and the output value of the inertial navigation system, thus correcting the attitude of an airplane and the errors of sensors. The attitude correction apparatus of the present invention includes a camera-type solar sensor for detecting the sun, a signal processing unit for receiving and synchronizing information, and a data collection processing unit for performing post-processing on information, thus correcting an error.
