| 20110096960 | METHOD AND APPARATUS FOR EYE-SCAN AUTHENTICATION USING A LIQUID LENS - A method and apparatus for providing eye-scan authentication using an adaptive liquid lens are disclosed. For example, in one embodiment, the method receives a request for eye-scan authentication from a mobile endpoint device of a user, wherein the request comprises a first retinal image of the user captured using an adaptive liquid lens of the mobile endpoint device. The method obtains a second retinal image of the user, wherein the second retinal image is a stored retinal image of the user. The method authenticates the first retinal image against the second retinal image. In another embodiment, the method captures a first retinal image of a user via a mobile endpoint device of the user, wherein the mobile endpoint device comprises an adaptive liquid lens. The method then sends a request for eye-scan authentication from the mobile endpoint device over a network, wherein the request comprises the first retinal image. | 04-28-2011 |
| 20110098033 | METHOD AND APPARATUS FOR DYNAMICALLY PROCESSING AN ELECTROMAGNETIC BEAM - A method and apparatus for processing a terahertz frequency electromagnetic beam are disclosed. For example, the method receives the terahertz frequency electromagnetic beam via a metamaterial having a plurality of addressable magnetic elements, where a resonant frequency of each of the plurality of addressable magnetic elements is capable of being programmably changed via an adjustment, and activates selectively a subset of the plurality of addressable magnetic elements to manipulate the terahertz frequency electromagnetic beam. | 04-28-2011 |
| 20110293268 | METHOD AND APPARATUS FOR PROVIDING COMMUNICATION USING A TERAHERTZ LINK - A method and apparatus for establishing a terahertz link using a multi-element lens array that comprises a liquid lens are disclosed. For example, the method receives detected terahertz signals from one or more detectors, where a liquid lens is deployed with each of the one or more detectors. The method determines, for each of the detected signals, if the detected signal is out of focus, and applies a corrective voltage to each liquid lens that corresponds to a detected terahertz signal that is out of focus, wherein the corrective voltage adjusts a focus of the detected signal. The method measures a signal-to-noise ratio of the detected signals, and establishing a terahertz link via at least one of the detected terahertz signals with a highest signal-to-noise ratio. | 12-01-2011 |

| 20090068241 | DEPOSITION OF METALS ONTO NANOTUBE TRANSPARENT CONDUCTORS - This invention is directed to compositions and methods of incorporating metal particles into carbon nanotube films, sheets, and networks. Metal salts that are soluble in water, alcohol, polar organic solvents, and mixtures thereof are used to deposit metal particles onto carbon nanotube films, sheets, and networks. Metal salts increase conductance of nanotube films by spontaneously depositing gold on the nanotube. The concentration and time of exposure to metal salt solution allows the tuning of conductivity and transparency for a transparent carbon nanotube network. Metal salts added to nanotube ink add functional properties of the metal to nanotube conductors. | 03-12-2009 |
| 20100028634 | METAL OXIDE COATINGS FOR ELECTRICALLY CONDUCTIVE CARBON NANOTUBE FILMS - This invention are directed to methods and compositions preferably comprising non-silicate metal oxides as a treatment for transparent electrically conductive carbon nanotube coatings that prevents resistance changes during exposure to environmental conditions; both chemical effects (for example, water, heat, light, or other compounds) and physical effects (for example, abrasion, scratch, adhesion). The protective properties instilled by these coatings occur preferably through the careful selection of the appropriate metal oxide depending on the application. | 02-04-2010 |
| 20100136224 | STABLE NANOTUBE COATINGS - The present invention relates to purified transparent carbon nanotube (CNT) conductive layers or coatings that comprise at least one additional material to form a composite. Adding a material to the CNT layer or coating improves conductivity, transparency, and/or the performance of a device comprising a transparent conductive CNT layers or coating This composite may be used in photovoltaic devices, OLEDs, LCD displays, or touch screens. | 06-03-2010 |

| 20090073921 | Data forwarding in hybrid mesh networks - A system and method are disclosed for forwarding data in hybrid wireless mesh networks. The method includes configuring a number of mesh network nodes as Potential Relay Nodes (PRNs) in an overlay network associated with a hybrid wireless mesh network, streaming data packets from a source node to a destination node using a native data forwarding algorithm of the hybrid wireless mesh network, dynamically identifying Relay Nodes (RNs) among PRNs in the overlay network, creating secondary paths for sending data packets towards selected RNs in the overlay network, and relaying data packets from RNs to the destination node using the overlay network. | 03-19-2009 |
| 20110033044 | Secure Open-Air Communication System Utilizing Multi-Channel Decoyed Transmission - A secure, open-air communication system utilizes a plurality of “decoy” data signals to hide one or more true data signals. The true data signal(s) are channel hopped with the plurality of decoy data signals to form a multi-channel “scrambled” output signal that is thereafter transmitted in an open-air communication system. The greater the number of decoy signals, the greater the security provided to the open-air system. Further security may be provided by encrypting both the true and decoy signals prior to scrambling and/or by utilizing a spatially diverse set of transmitters and receivers. Without the knowledge of the channel assignment(s) for the true signal(s), an eavesdropper may be able to intercept (and, with time, perhaps descramble) the open-air transmitted signals, will not be able to distinguish the true data from the decoys without also knowing the channel assignment(s). | 02-10-2011 |
| 20110148647 | Manhole Security Device and Methods Thereof - A security device for detecting the position of a manhole cover includes a pinger device, such as an acoustic pinger, that transmits a signal in the direction of the expected position of the manhole cover. The device takes energy samples to determine if the signal has been reflected back by the manhole cover. If the device determines the signal has not been reflected, it determines that the manhole cover has been moved from the expected position. In response, the device captures an image of an area around the expected position of the manhole cover. In addition, the device can notify a remote security station via a network that the manhole cover has been moved. | 06-23-2011 |
