Disclosed herein are a method of attaching a die using a self-assembling monolayer and a package substrate including a die attached thereto using a self-assembling monolayer. A first self-assembling monolayer formed on a die and a second self-assembling monolayer formed on a substrate are provided with the same hydrophilic or hydrophobic functional group, so that the die is attached to the substrate using an attractive force acting between the first and second self-assembling monolayers. An accuracy of alignment between the die and the substrate can be improved by the simple solution.

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.

A haptic feedback device includes a touch panel and an actuator. The touch panel is provided as a haptic device requiring a vibration. The actuator provides a driving force in a direction opposite to touch pressure provided to a touch surface of the touch panel when the touch pressure is less than a maximum critical touch pressure, and stops providing the driving force when the touch pressure is equal to or greater than the maximum critical touch pressure, so that the position of the touch panel changes according to the touch pressure.
