C01B031/00

US Classification:

423445B, 977DIG 1

Abstract:

A solid phase or form of carbon is based on fullerenes with thirty six carbon atoms (C). The Cstructure with Dsymmetry is one of the two most energetically favorable, and is conducive to forming a periodic system. The lowest energy crystal is a highly bonded network of hexagonal planes of Csubunits with AB stacking. The Csolid is not a purely van der Waals solid, but has covalent-like bonding, leading to a solid with enhanced structural rigidity. The solid Cmaterial is made by synthesizing and selecting out Cfullerenes in relatively large quantities. A Crich fullerene soot is produced in a helium environment arc discharge chamber by operating at an optimum helium pressure (400 torr). The Cis separated from the soot by a two step process. The soot is first treated with a first solvent, e. g. toluene, to remove the higher order fullerenes but leave the C.

International Classification:

H03H 9/24

US Classification:

333186, 333197, 977752

Abstract:

A tunable nanoscale resonator has potential applications in precise mass, force, position, and frequency measurement. One embodiment of this device consists of a specially prepared multiwalled carbon nanotube (MWNT) suspended between a metal electrode and a mobile, piezoelectrically controlled contact. By harnessing a unique telescoping ability of MWNTs, one may controllably slide an inner nanotube core from its outer nanotube casing, effectively changing its length and thereby changing the tuning of its resonance frequency. Resonant energy transfer may be used with a nanoresonator to detect molecules at a specific target oscillation frequency, without the use of a chemical label, to provide label-free chemical species detection.

Abstract:

An embodiment of a nanomechanical frequency detector includes a support structure and a plurality of elongated nanostructures coupled to the support structure. Each of the elongated nanostructures has a particular resonant frequency. The plurality of elongated nanostructures has a range of resonant frequencies. An embodiment of a method of identifying an object includes introducing the object to the nanomechanical resonance detector. A resonant response by at least one of the elongated nanostructures of the nanomechanical resonance detector indicates a vibrational mode of the object. An embodiment of a method of identifying a molecular species of the present invention includes introducing the molecular species to the nanomechanical resonance detector. A resonant response by at least one of the elongated nanostructures of the nanomechanical resonance detector indicates a vibrational mode of the molecular species.

International Classification:

G06F 928

US Classification:

708200

Abstract:

A processor particularly useful in multimedia applications such as image processing is based on a stream programming model and has a tiered storage architecture to minimize global bandwidth requirements. The processor has a stream register file through which the processor's functional units transfer streams to execute processor operations. Load and store instructions transfer streams between the stream register file and a stream memory; send and receive instructions transfer streams between stream register files of different processors; and operate instructions pass streams between the stream register file and computational kernels. Each of the computational kernels is capable of performing compound vector operations. A compound vector operation performs a sequence of arithmetic operations on data read from the stream register file, i. e. , a global storage resource, and generates a result that is written back to the stream register file.

Abstract:

Systems and methods are disclosed for secure messaging and content sharing. In one implementation, a processor receives a content item in a first format, the content item being associated with an intended recipient, converts the content item into a second format, provides the content item, as converted into the second format, to a device associated with the intended recipient, receives, from the device associated with the intended recipient, one or more inputs in relation to a segment of the content item, processes the one or more inputs to determine that an authentication action is being performed with respect to the segment of the content item, and based on a determination that the authentication action is being performed with respect to the segment of the content item, provides an instruction to present the segment of the content item at the device associated with the intended recipient.

Abstract:

A system that has electrically or electro-pneumatically actuated aerodynamic structures. An electric or electro-pneumatic actuator is employed, which receives signals from an existing anti-lock braking system (ABS) controller to determine when actuation occurs. Other systems are also provided that feature electric or electro-pneumatic actuation, including underbody skirts and scoops, as well as inflatable tractor-trailer gap sealing devices, adjustable tractor-trailer gap sealing flaps and inflatable trailer upper streamlining devices. Electronic control units (ECUs) for aerodynamic system control interfacing with alternate sensors for calculating speed are also provided. Satellite navigation, platooning awareness and managed pressure reserve capability can be employed with the aerodynamics ECU.

Abstract:

Systems and methods are disclosed for secure messaging and content sharing. In one implementation, a processor receives a message associated with a recipient, provides, to the recipient, a notification pertaining to the message, and, based on a determination of a performance of one or more authentication actions with respect to the message, provides the recipient with access to the message. In another implementation, a processor receives a message including one or more content segments, receives inputs in relation to at least one of the content segments, processes the inputs to determine that an authentication action is being performed with respect to the one of the one or more content segments, and based on a determination that the authentication action is being performed with respect to the one of the one or more content segments, presents the at least one of the one or more content segments.
