20090231205 | CARBON NANOTUBE BASED VARIABLE FREQUENCY PATCH-ANTENNA - A carbon nano-tube based variable frequency patch antennas which utilizes a dense network of semiconducting carbon nanotubes as the antenna patch is provided. In preferred embodiments, the resonant frequency of the antenna can be tuned electrically by adjusting appropriate sections of its back-gate, thus altering the effective size of the patch antenna and radiation beam direction can be formed and stirred. In one embodiment, a patch antenna comprises a dense network or thick layer of semiconducting carbon nanotubes grown or deposited on an oxide layer to form a carbon nanotube patch and a partitioned backgate is positioned below the oxide layer with a ground-plane formed from a thin layer of metal. In other embodiments, a patch antenna includes an array of carbon nanotube patches and the ground-plane doubles as the backgate. | 09-17-2009 |

20100144296 | Carbon Nanotubes for Wireless Communication and Radio Transmission - Described herein are systems and methods in which a carbon nanotube (CNT) is used as a demodulator of amplitude-modulated (AM) signals. Due to the nonlinear current-voltage (I-V) characteristics of a CNT, the CNT induces rectification of an applied RF signal enabling the CNT to function as a demodulator of an amplitude-modulated (AM) RF signal. By properly biasing the CNT such that the operating point is centered on the maximum portion of the I-V curve, the demodulation effect of the CNT can be maximized. The present invention is useful for possible nanoscale wireless communications systems, e.g., nanoscale radios. | 06-10-2010 |

20130086113 | SECURE DATA ACCESSING SYSTEM AND METHOD - A system and method for accessing data located behind a security mechanism is provided. In the preferred embodiment, the system may use the common HTTP protocol and JDBC drivers. In more detail, a client may execute a Java applet that generates database proxy objects that are communicated to an application server using the HTTP protocol. The application server may use a servlet to process the objects and generate database requests using JDBC drivers so that the data is retrieved from the database for the client Java applet without the security problems. | 04-04-2013 |
