Abstract: The present invention relates to a total reflection type rain sensor using a mirror, which is attached to a glass of a vehicle to detect raindrops falling onto the glass of the vehicle and outputs a signal capable of controlling speed and cycle of a wiper of the vehicle according to the amount and falling frequency of raindrops detected.

Abstract: Disclosed is a method of manufacturing a fingerprint recognition home key having an offset structure of a decorative part. The method includes: (a) preparing an injection molded product having a shape of a home key and provided with a fingerprint recognition sensor, (b) applying a bonding material or an adhesive to an upper side of a film of the fingerprint recognition sensor, (c) bonding an external member to the upper side of the film of the fingerprint recognition sensor to which the bonding material or the adhesive is applied, and (d) assembling the decorative part to have a height difference from to the external member.

Abstract: Disclosed is a method of manufacturing a fingerprint recognition home key. In this method, an external member having a high dielectric constant is bonded to a film of a fingerprint recognition sensor, thereby increasing a fingerprint recognition rate, reducing manufacturing time, and providing a pleasant outer appearance. The method includes preparing an injection molded product having a shape of a home key and provided with a fingerprint recognition sensor, applying a bonding material or an adhesive to an upper side of a film of the fingerprint recognition sensor, and bonding an external member to the upper side of the film of the fingerprint recognition sensor to which the bonding material or the adhesive is applied.
