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: A wave guide structure for key module of mobile device and the forming method thereof is provided. A wave guide structure for key module of mobile device comprises, a substrate equipped with a menu key and a back key; a light shielding frame equipping a internal hollow formed surrounding and covering every side of a light emitting member protruding on a side of a substrate in an area equipped with a menu key and a back key and having a greater thickness than the protruding size of the light emitting member; a white sheet equipped through a internal hollow of the light shielding frame; a wave guide sheet laminated on the white sheet; and a tape member attaching to a back of the light shielding frame is provided.

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.
