Provided are a semiconductor package and a module printed circuit board (PCB) for mounting the same. Each of the semiconductor package and the module PCB includes a substrate, a first-type pad structure disposed in a first region of the substrate, and a second-type pad structure disposed in a second region of the package substrate. The first-type pad includes a first conductive pad disposed on the package substrate and a first insulating layer coated on the package substrate. The first insulating layer has a first opening by which a portion of a sidewall of the first conductive pad is exposed, and partially covers the first conductive pad. The second-type pad includes a second insulating layer coated on the package substrate to have a second opening and a second conductive pad disposed on the package substrate in the second opening to have an exposed sidewall. In this structure, the semiconductor package and the module PCB can have an excellent resistance to physical and thermal stresses to enhance structural reliability.
Abstract:
A system for protecting copyrights of digital content includes a digital content server for providing digital content containing an address of a digital content server, performing authentication of the digital content, and generating execution/non-execution information representing an authentication result for the digital content. A mobile terminal receives the execution/non-execution information from the digital content server and executes the digital content according to the execution/non-execution information. A method may include the steps of detecting an address of a digital content server contained in the digital content; accessing the digital content server using the detected address and transmitting identification (ID) information necessary for executing the digital content to the digital content server; performing authentication of the digital content in the digital content server using the ID information, and generating execution/non-execution information representing an authentication result for the digital content, and transmitting the execution/non-execution information to the mobile terminal.

An apparatus and method for controlling a sensor node are provided that may calculate an azimuth angle and a slope of the sensor node using a 2-axis magnetic sensor and a 3-axis acceleration sensor, and may detect a target approaching the sensor node. The apparatus may include a calculation unit to calculate an azimuth angle and a slope of a sensor node, based on a magnetic values measured by a 2-axis magnetic sensor and a acceleration values measured by a 3-axis acceleration sensor; a sensor control unit to filter the magnetic values and the vibration values and to amplify the filtered magnetic values and the filtered vibration values, when the azimuth angle and the slope are calculated; and a detection unit to detect a target based on the amplified magnetic values and the amplified vibration values.
Abstract:
A test socket may include a socket frame, a plate, a socket pin and a link. The socket frame may have a slot configured to accept an object. The plate may be free to move in the slot along an inserting direction of the object to support a lower surface of the object. The socket pin may be movably arranged in a direction substantially perpendicular to the inserting direction of the object. The socket pin may selectively make contact with a tab of the object. A link may be pivotally connected to the socket pin and the plate. Thus, the socket pin of the test socket may avoid dragging along the tab of the object during insertion, and accordingly, the tab of the object may avoid damage.
Abstract:
The present invention relates to a method and system for automatically verifying a computer vaccine database and, more particularly, to a method and system for automatically verifying a computer vaccine database, which is capable of automatically verifying and modifying a vaccine database mounted on a vaccine engine so that a normal program is not recognized as viruses or malicious codes by storing information about the normal program in the vaccine database in order to remove computer viruses or malicious codes. According to the present invention, a file set of the latest vaccine database can be rapidly collected and processed, and the problems of a vaccine database file provided by a vendor can be checked in advance. Accordingly, there are advantages in that a function of alarming error conditions and a process of reporting error in a vaccine database update process can be automated.
