20110057775 | BIOMETRIC AUTHENTICATION DEVICE - Disclosed herein is a biometric authentication device. The biometric authentication device includes a main body for forming a hand grip surface and constituting an entire framework of the biometric authentication device. At least one light source is disposed on one side of the main body and configured to radiate light. A reflection unit is included in the main body and attached to a side opposite that of the light source, the reflection unit allowing the radiated light to be incident on a hand and re-reflecting light that is incident on and reflected from the hand. An imaging device is disposed on the side of the main body, which is identical to the side on which the light source is disposed, and is configured to acquire biometric information of the hand by forming images of re-reflected light. An authentication/verification unit performs personal authentication using the biometric information. | 03-10-2011 |
20110063077 | VEIN AUTHENTICATION APPARATUS USING TOTAL INTERNAL REFLECTION - Disclosed herein is a vein authentication apparatus. The vein authentication apparatus includes a protective panel provided with a finger-resting surface, a light entry hole and a light exit hole and configured to totally reflect light, a light source located adjacent to the light entry hole of the protective panel and configured to emit the near infrared rays, an imaging element located adjacent to the light exit hole of the protective panel and configured to acquire a vein pattern, a light entry-side diffraction element located in the light entry hole of the protective panel and configured to guide the light toward the fingertip, a light exit-side diffraction element located in the light exit hole of the protective panel and configured to guide the light toward the imaging element, and an authentication unit configured to perform vein authentication using the vein pattern. | 03-17-2011 |
20130169427 | TIRE PRESSURE MONITORING SYSTEM - Disclosed herein is a tire pressure monitoring system, including an electrical device unit including a pressure sensor for detecting an air pressure of a tire; a housing that is accommodated in the electrical device unit and into which the air pressure of the tire is introduced; a valve antenna having one end that is inserted into the housing and the other end into which the air pressure of the tire is introduced; a conduction member having one end that is electrically connected to the electrical device unit and the other end that is electrically connected to the valve antenna; and a coupling member fixing and coupling the housing and the valve antenna to each other, wherein the valve antenna transmits a pressure signal about the air pressure of the tire, which is detected by the pressure sensor, to a receiver of a vehicle. | 07-04-2013 |
