Abstract: Disclosed is a method for mobile-key service, in which user authentication is performed through NFC between an SE and a door lock. Herein, a mobile phone periodically checks a call service areas of a mobile radio communication network, and the mobile phone enables the NFC function based on a result of the call service area checking operation, and if the mobile phone approaches the door lock, the mobile-key is transmitted to the door lock through the NFC function, and thus the user authentication can be performed.

Abstract: An apparatus for measuring ganglion cells may include: a light generation unit configured to irradiate a first light signal polarized in a first direction and a second light signal polarized in a second direction perpendicular to the first direction to a subject; a reflected light processing unit configured to generate an amplification signal corresponding to an image of the subject using a first reflection signal, which is the first light signal reflected from the subject, and a second reflection signal, which is the second light signal reflected from the subject; and an image processing unit configured to measure ganglion cells in the subject using the amplification signal. The apparatus may be used to count the number of normal ganglion cells in the retina by measuring a phase difference of two lights polarized in different directions. The apparatus may also be used to monitor the progress of glaucoma.

Abstract: Disclosed is a method of interactive display that includes providing a touch-based display screen capable of stereoscopic displaying of object images that further includes displaying a plurality of object images on the display screen, wherein at least a first of the object images is selectable and displayed so as to appear to be located at least partially in a zero-plane of the display screen, wherein at least a second of the object images is displayed so as to appear to be located at least one of inwardly and outwardly of the zero-plane, receiving a first input at a location of the display screen substantially corresponding to the first of the object images, and identifying the first input as corresponding to the first of the object images that is selectable and taking at least one further action upon the identification.

Abstract: An optical module for irradiation of laser beams includes a mirror mount, a rotation shaft coupled to a center of the mirror mount, a vibration member coupled to one end of the mirror mount and the vibration member vibrating the end of the mirror mount in front-and-rear directions, a mirror fixed to the mirror mount and the mirror irradiating laser beams by performing reciprocal rotational motion with the mirror mount with respect to the rotation shaft, and a weight arranged on at least one of a first side and a second side of the mirror mount. The weight is interposed between the rotation shaft and the at least one of the first side and the second side to compensate concentricity of the mirror.
