20120118608 | CONDUCTIVE CONTACT TERMINAL FOR SURFACE MOUNTING ON SUBSTRATE - The present invention provides a conductive contact terminal for surface mounting on a substrate. In the conductive contact terminal, an elastic core imparts elasticity to the contact terminal. A metal layer covers the outer portion of the elastic core. A conductive adhesive layer is interposed between the elastic core and the metal layer to bond the elastic core and the metal layer to each other. The conductive contact terminal has a low electrical resistance, does not exhibit a deformation in the material even in a high-temperature reflow soldering process, and does not lose conductivity even though a metal layer, which imparts electrical conductivity to the conductive contact terminal, is broken. | 05-17-2012 |
20110267795 | ELECTRONIC PASSPORT CASE FOR PREVENTING LEAKAGE OF INFORMATION AND IMPROVING RECOGNITION RATE - The present invention relates to an electronic passport case for preventing a leakage of information and improving a recognition rate. More particularly, the present invention relates to an electronic passport case that prevents a leakage of information by shielding electromagnetic waves which reach an electronic chip and improves a recognition rate of the electronic chip incorporated in the electronic passport in order to prevent personal information of an electronic passport owner stored in the electronic chip incorporated in the electronic passport from being leaked arbitrarily unintentionally. The present invention provides an electronic passport case for preventing a leakage of information and improving a recognition rate, including an electromagnetic wave shielding layer formed to cover an electronic passport and preventing an electronic wave from reaching an electronic chip incorporated in the electronic passport. According to the present invention, it is possible to prevent biological information and personal information of an electronic passport owner recorded in an electronic chip of an electronic passport from being arbitrarily leaked and misused, and to perform communication between the electronic chip and a recognizer stably. | 11-03-2011 |
