20100283528 | NANOTUBE-ON-GATE FET STRUCTURES AND APPLICATIONS - Under one aspect, non-volatile transistor device includes a source and drain with a channel in between; a gate structure made of a semiconductive or conductive material disposed over an insulator over the channel; a control gate made of a semiconductive or conductive material; and an electromechanically-deflectable nanotube switching element in fixed contact with one of the gate structure and the control gate structure and is not in fixed contact with the other of the gate structure and the control gate structure. The device has a network of inherent capacitances, including an inherent capacitance of an undeflected nanotube switching element in relation to the gate structure. The network is such that the nanotube switching element is deflectable into contact with the other of the gate structure and the control gate structure in response to signals being applied to the control gate and one of the source region and drain region. | 11-11-2010 |

20100022045 | SENSOR PLATFORM USING A NON-HORIZONTALLY ORIENTED NANOTUBE ELEMENT - Sensor platforms and methods of making them are described. A platform having a non-horizontally oriented sensor element comprising one or more nanostructures such as nanotubes is described. Under certain embodiments, a sensor element has or is made to have an affinity for an analyte. Under certain embodiments, such a sensor element comprises one or more pristine nanotubes. Under certain embodiments, the sensor element comprises derivatized or functionalized nanotubes. Under certain embodiments, a sensor is made by providing a support structure; providing one or more nanotubes on the structure to provide material for a sensor element; and providing circuitry to electrically sense the sensor element's electrical characterization. Under certain embodiments, the sensor element comprises pre-derivatized or pre-functionalized nanotubes. Under other embodiments, sensor material is derivatized or functionalized after provision on the structure or after patterning. Under certain embodiments, a large-scale array of sensor platforms includes a plurality of sensor elements. | 01-28-2010 |
20100025659 | NON-VOLATILE ELECTROMECHANICAL FIELD EFFECT DEVICES AND CIRCUITS USING SAME AND METHODS OF FORMING SAME - Under one aspect, a field effect device includes a gate, a source, and a drain, with a conductive channel between the source and the drain; and a nanotube switch having a corresponding control terminal, said nanotube switch being positioned to control electrical conduction through said conductive channel. Under another aspect, a field effect device includes a gate having a corresponding gate terminal; a source having a corresponding source terminal; a drain having a corresponding drain terminal; a control terminal; and a nanotube switching element positioned between one of the gate, source, and drain and its corresponding terminal and switchable, in response to electrical stimuli at the control terminal and at least one of the gate, source, and drain terminals, between a first non-volatile state that enables current flow between the source and the drain and a second non-volatile state that disables current flow between the source and the drain. | 02-04-2010 |

20110297219 | METHOD AND MATERIALS FOR THE FABRICATION OF CURRENT COLLECTING STRUCTURES FOR PHOTOVOLTAIC DEVICES - A bus grid structure is affixed to a photovoltaic device utilizing a double-sided adhesive tape in which one of the adhesive layers is electrically conductive and the other is electrically resistive. The tape is affixed to a photovoltaic device via the electrically resistive adhesive. Grid wires are applied to a top electrode of the photovoltaic device, and portions of those grid wires are adhered to the electrically conductive adhesive. A bus bar is also adhered to the electrically conductive adhesive so as to contact the portions of the grid wire. The assembly is laminated so as to bond the grid wires to the photovoltaic device and to the bus bar. Further disclosed are devices fabricated according to this method as well as electrically conductive double adhesive tapes utilized in the process. | 12-08-2011 |

20100244818 | APPARATUS AND METHOD FOR TRANSDUCING AN IN VITRO OR MAMMALIAN SYSTEM WITH A LOW-FREQUENCY SIGNAL - Method and apparatus for generating and selecting low-frequency time-domain signals capable of transducing a mammalian system, to produce an agent-specific effect on the system, are disclosed. Low-frequency time-domain signals are generated in the presence of an injected magnetic stimulus, and the resulting signals are selected by a scoring algorithm, and optionally, by testing each signal identified by the scoring algorithm for its ability to produce an agent-specific response in a in vitro system containing components that are responsive to the agent. The selected signals are used to transduce the mammalian system by applying the signals to an electromagnetic transduction coil that holds the sample. | 09-30-2010 |

20080295954 | END EFFECTOR AND METHODS FOR CONSTRUCTING COMPOSITE MEMBERS - An end effector, and methods for constructing composite members, in which a compaction roller and redirect rollers translate synchronously along the compaction axis. Additionally, the end effector includes an advantageous arrangement of spools and rollers that directs tow to the redirect rollers at substantially a right angle. Movement of the compaction roller along the compaction axis induces little, if any, changes in tow tension. The substantially constant tow tension advantageously reduces rewinding of the tow supply spools, which can degrade the quality of the lay up and contribute to despooling problems. | 12-04-2008 |
20110240218 | HEATING METHOD FOR A COMPOSITE LAMINATOR - A method of fabricating a composite item may include dispensing a composite material comprising a reinforcement and a resin. The method may further include energizing an infrared heat source. The infrared heat source may tend to generate a wavelength of electromagnetic radiation that is preferentially absorbed by the reinforcement. The method may additionally include controlling power to the infrared heat source to cause the infrared heat source to emit a wavelength of electromagnetic radiation that is absorbed by the resin to a relatively greater extent than the wavelength of electromagnetic radiation that is absorbed by the reinforcement. | 10-06-2011 |
20110315325 | Backing Film Removal for Fiber Placement Machine - An apparatus and associated method for removing backing film from tape during a fiber placement process. A passive (non-powered) take-up roller is used to wind up the backing film that has been separated from the tape. | 12-29-2011 |
