20100313680 | INPUT DEVICE - An input device that is capable of sensing how hard a user is pressing when contacted is disclosed. The input device includes a pressure sensing unit generating an electrical signal in accordance with pressure applied on one surface of the pressure sensing unit and a fixed resistance making a parallel electrical connection with the pressure sensing unit. Thus, not only can the input device receive a form of information that is changed proportionally in accordance with the pressure applied by the user, but the deviation in electrical characteristics that may occur during the manufacturing of different products can also be reduced. Also, by adjusting the resistance value of the fixed resistance, the sum of the resistance values by the parallel connection between the fixed resistance and the pressure sensitive resistance can be adjusted so that the electrical signal generated by the input device through pressing can be adjusted. | 12-16-2010 |

20080309574 | SYSTEM AND METHOD FOR PREVENTING COPYING OF ELECTRONIC COMPONENT DESIGNS - Techniques are provided to prevent undesired and/or unauthorized analysis and access to electronic components designs. A shield can be utilized to prevent invasive and/or non-invasive analysis methods such as the use of x-rays to determine the structural configuration and/or component makeup of an embedded antenna. In addition, a damageable material that can be utilized alone or in conjunction with the shield is also provided. When attempting to access the antenna and/or components included therein, any inappropriate force or exposure to certain elements, such as heat, will cause the material and the antenna and/or the components therein to be damaged or melted beyond a point of useful recognition for the entity. Furthermore, thin films can be utilized to construct one or more portions of the antenna to the same effect. In addition, the antenna and/or components can be configured for actively reconfiguring a resonant frequency of the antenna. | 12-18-2008 |
