The method includes the steps of: providing a fingerprint sensor having a number of detecting elements beneath a top surface of the fingerprint sensor, the detecting element is used to detect changes of capacitance over a portion of a finger; forming a metal mesh layer over the top surface of the fingerprint sensor, wherein metal lines of the metal mesh layer are formed periodically and each of them is located between two adjacent detecting elements; forming a passivation layer on the metal mesh layer to shape a concave-convex top surface; and filling concave portions of the passivation layer with a Diamond-Like Carbon (DLC) material. A convex portion of the passivation layer is substantially above the metal line of the metal mesh layer.

Abstract: The present invention is to provide an IP camera having repeater functions, which includes an image-capturing module for capturing images, an image processor for processing the images, a central processor including a network communication module for activating the repeater functions and mediating communication between a root wireless access point (WAP) and an external device, and an antenna electrically connected to the network communication module in order for the IP camera to make wireless connection to the root WAP, upload the images to the Internet and serve as a repeater between the two WAPs, and a memory configured for storing operating software, a plurality of service set identifiers (IDs) and an authentication key. Due to the repeater functions of the IP camera, the external device can identify the IP camera by the IDs and then connect to the Internet, even if the external device is outside coverage of a wireless LAN.

Abstract: A silicon wafer having colored top side is disclosed in the present invention. The silicon wafer includes: a wafer; a first semi-conductor layer, formed on at least a portion of a top side of the wafer, having periodical structures to form a grating pattern, and a second semi-conductor layer, formed on the first semi-conductor layer with a bottom side substantially fully contacted with the periodical structures. The first semi-conductor layer and the second semi-conductor layer form a photonic crystal layer and work to reflect a predetermined wavelength range of incident visible light beams. The present invention provides a silicon wafer which can reflect specified color(s) from the surface facing external light beams. Therefore, dies from cutting the silicon wafer with functions to interact with external environment rather than packaged can have advantages to show some specified logo or trademark.

Abstract: A multi-function identification system is described in the present invention. The system includes an appliance and a number of keys. Under a registration process, the system allows multiple appliances to be controlled by a single key or an appliance can be controlled by different keys. The system can also allow users to set specified actions to be conducted after identification processes are completed. That satisfies requirements of a multi-function identification. Meanwhile, the key is a plug-and play and on-the-go product. It is desired that the key is a host used for other purpose.

Abstract: A printed circuit board having an electronic component embedded and a method making the same are disclosed. The printed circuit board has four electrically conductive layers and three core layers formed interleavedly. By properly removing a portion of the printed circuit board, the electronic component can be exposed. It has advantages that the exposed electronic component can be a CCD, CMOS or module. When the devices mentioned are embedded in the printed circuit board, one part of them can be exposed from the printed circuit board for normal functions. The overall thickness of the printed circuit board assembly can be minimized to meet the trend of compact design of electronic products.

Abstract: A portable device having fingerprint recognition function includes an image sensing unit, a microprocessor, a signal transmitting unit, a carrying member, a cleaning unit, and a housing. It is characterized that the cleaning unit removes residual fingerprint from the image sensing unit while the carrying member moves in and out of the housing. The portable device of the present invention is free from fingerprint residue and can reduce security risks.

Abstract: A portable fingerprint device is disclosed. The device includes an image sensing unit for capturing fingerprint images of a finger; a microprocessor, linked to the image sensing unit, for recording the fingerprint images of the finger, identifying the fingerprint images of the finger from a fingerprint database, receiving a command signal and transmitting a response signal; and a communication unit, connected to the microprocessor, for exchanging the command signal and the response signal between the microprocessor and a command device separated from the portable fingerprint device. The portable fingerprint device not only can identify fingerprints, but also can detect a sequence of finger motion, or “signature”, and use such information as part of the identification/authentication process.

Abstract: A method for building a connection channel between network terminals through a dynamic domain name server (DDNS) is applied to a network system including a DDNS, the Internet, and at least one private network including more than one network address translation (NAT) router and at least one network terminal linked to the Internet through the NAT routers sequentially. The network terminal detects usable linking information of related equipments between the network terminal and the DDNS, and writes the linking information into a web page under a domain name registered with the DDNS by the network terminal, or into the DDNS. Another network terminal on the Internet wanting to link to the network terminal can input the domain name and read the linking information either from the web page or by using a utility program to search the DDNS, thereby building a connection channel with the network terminal.

Abstract: A social contact service system for internet connected digital photos enables internet connected digital photo frames to be a social contact group. Via the social contact service system, any one of grouping internet connected internet connected digital photo frames would upload updated digital information to notify the members of the social contact group, and download another updated digital information from other members of the social contact group. Furthermore, with the desktop utility of a computer, other portal service system and an internet connected digital photo frame with control management, the digital contents in the social contact service system may be integrated and managed.

Abstract: An operation system of an internet connected digital photo frame includes local and remote storage units to store digital images, content settings relevant to homepages and connecting lists of groups, respectively. With control tools, a user may manage and edit the digital images and the customized content settings of homepages. Thus, such an internet connected digital photo frame is used as a social interface among the user and groups on internet.
