Abstract: Disclosed herein is a TPMS transmission module having a power saving function, the TPMS transmission module including: a micom outputting a switch turn-off control signal when a vehicle having the TPMS transmission module mounted therein is stopped; a switch supplying a power when the switch is turned on and blocking the supply of the power when it is turned off; an energy generator generating and outputting an electric power when a tire rotates; and a switch controller turning on the switch when the electric power of a predetermined voltage or more is generated in the energy generator and turning off the switch when a switch turn off control signal is output from the micom.

Abstract: Disclosed herein are an apparatus and a method for automatically recognizing a position of a wheel of a vehicle. The apparatus includes a rotation sensor unit sensing a variation in rotation of the wheel of the vehicle; a pressure sensor unit sensing a rate of variation in pressure of the wheel of the vehicle; and a sensor control unit judging the position of the wheel of the vehicle by the variation in rotation and the rate of variation in pressure obtained from the rotation sensor unit and the pressure sensor unit. The sensor control unit judges the position of the wheel of the vehicle by dw/dt×dp/dt, in which dw/dt is the variation in rotation and dp/dt is the rate of variation in pressure. The wheel is judged as a front wheel when a value of dw/dt×dp/dt has a negative (?) sign and the wheel is judged as a rear wheel when the value of dw/dt×dp/dt has a positive (+) sign.

Abstract: Disclosed herein is a biometric authentication device. The biometric authentication device according to the present invention is configured such that it blocks visible light using an authentication button, the inside of which is opened or closed by a finger so as to realize the small size and slim shape of a biometric authentication device, and blocks infrared light or allows infrared light to pass while a driving unit moves vertically or horizontally by the operation of the authentication button. Accordingly, in the biometric authentication device, a camera module captures a normal image in normal mode, and captures an infrared pattern reflected from a finger in a vein authentication mode to perform biometric authentication.

Abstract: Disclosed herein are a tire autolocation system and method using an angular sensor. The present invention includes an air pressure detector and a body control module, wherein the air pressure detector includes an air pressure detecting module detecting air pressure of a tire and angular velocity sensors symmetrically mounted at left and right sides and detecting angular velocity of the tire and the body control module includes a receiver and reads the left/right tires with (+) and (?) angular signals transmitted from the angular velocity sensors through the receiver.

Abstract: Disclosed herein is a touch screen device 100a, including: a touch screen 110, and actuators 120a, 120b, and 120c that drive the touch screen 110 in two dimensions including an up and down direction or in three dimensions. The touch screen device 100a can be driven in an up and down direction vertical to the touch screen, thereby making it possible to transfer a realistic touch sense such as a click sense, a dialing sense, and a surface texture sense to a user.
