  • Patent number: 7856128
    Abstract: A method of correcting distortion caused by fingerprint input sensors of heterogeneous fingerprint recognition systems. The method includes a first step of fabricating a measurement pattern for measuring resolutions of a fingerprint input sensor, a second step of measuring image resolutions of an image, acquired by the fingerprint input sensor, using the fabricated measurement pattern for predetermined locations and directions, a third step of designing control lines for compensating for the distortion caused by the fingerprint input sensor, based on the measured resolutions, a fourth step of obtaining average horizontal and vertical resolutions of the acquired image, a fifth step of modeling the control lines based on a ratio of the average horizontal resolution to the vertical average resolution, and a sixth step of compensating for the distortion of the acquired image based on results of the modeling.

  • Publication number: 20100015362
    Abstract: An apparatus for electroless plating includes a plating bath containing an aqueous metal salt solution, and a magnetic field generator for generating a magnetic field. An object to be plated is immersed in the solution. The magnetic field generated by the magnetic field generator increases the level at which the metal ions are attracted to a surface of the object. Therefore, a layer of plating of good quality may be formed at a rapid rate.

  • Publication number: 20090324946
    Abstract: Highly porous acicular mullite bodies are prepared. A green body containing mullite precursors and a porogen is formed using a wet method. The green body is heated to sequentially remove any binder, the porogen and calcine it. The calcined body is mullitized. The process formed a calcined body that has excellent strength and can be handled easily. The mullitized body has very high porosity, small pores and has excellent fracture strength.

  • Patent number: 7576437
    Abstract: Example embodiments may be directed to a printed circuit board having an insulating substrate, pads disposed on the surface of the insulating substrate, a solder resist, and a solder moving portion. Leads of a semiconductor package may be mounted on the insulating substrate. The pads to which the leads of the semiconductor package are connected may be disposed on the surface of the insulating substrate. The solder resist layer may cover the insulating substrate, but may also contain openings exposing at least a portion of the pads to which the leads of the semiconductor package are connected. During the process by which each semiconductor lead is connected to a pad, the solder moving portion on the pad may allow an adhesion solder coating each of the leads of the semiconductor package to move towards a shoulder portion of the semiconductor package leads.
