  • Patent number: 11241833
    Abstract: A device and method for printing 3D articles including electronic and functional elements including 3D printer and a plasma jet printer based on a dielectric barrier atmospheric pressure plasma jet system in which both printing and in-situ treatment and post-deposition treatment can be carried out to tailor the materials characteristics. Plasma jet printer comprising of electrodes in the nozzle/print head for applying electric field and generating atmospheric plasma that could be used for non-gravity based highly directional printing in any direction. Integration of dielectric barrier plasma printer and plasma treatment jets with the 3D printer increases the capability of embedding high performance electronics in a 3D printed structure aiding in additive manufacturing of functional devices. Ability to use a range of materials for print head assembly including micro machined silicon increases the resolution of the plasma jet printer to sub-micron level.

  • Patent number: 11244775
    Abstract: An all-printed physically unclonable function based on a single-walled carbon nanotube network. The network may be a mixture of semiconducting and metallic nanotubes randomly tangled with each other through the printing process. The unique distribution of carbon nanotubes in a network can be used for authentication, and this feature can be a secret key for a high level hardware security. The carbon nanotube network does not require any advanced purification process, alignment of nanotubes, high-resolution lithography and patterning. Rather, the intrinsic randomness of carbon nanotubes is leveraged to provide the unclonable aspect.

  • Patent number: 10691771
    Abstract: Systems and methods for allowing analog Ising machines to be able to run Integer Linear Programming (“ILP”) problems, i.e. a compilation method for setting the state of the physical memory units, flexible to be adapted to each specific device. The method describes how variables and numeric parameters which specify the problem can be hard-coded (embedded and physically represented) in the hardware circuitry of the device in a deterministic way, with a pre-determined bound on the number of required physical spins to be used in the Ising device.

  • Patent number: 8557576
    Abstract: The present disclosure provides ex vivo-derived mineralized three-dimensional bone constructs. The bone constructs are obtained by culturing osteoblasts and osteoclast precursors under randomized gravity vector conditions. Preferably, the randomized gravity vector conditions are obtained using a low shear stress rotating bioreactor, such as a High Aspect Ratio Vessel (HARV) culture system. The bone constructs of the disclosure have utility in physiological studies of bone formation and bone function, in drug discovery, and in orthopedics.

  • Publication number: 20130114775
    Abstract: A process for producing isotopes by continuously flowing a liquid stream, carrying capsules of target nuclei (NP-237) in solution, through a nuclear reactor (a TRIGA style nuclear reactor). Upon removal from the core of the nuclear reactor and after allowing for the decay of Np-238 to Pu-238, the capsules are emptied and the mixture of elements and isotopes are chemically separated using solvent extraction or ion exchange.

  • Patent number: 8260770
    Abstract: Method and systems for editing data from a query result include requesting a query result using a unique collection identifier for a collection of individual files and a unique identifier for a configuration file that specifies a data structure for the query result. A query result is generated that contains a plurality of fields as specified by the configuration file, by combining each of the individual files associated with a unique identifier for a collection of individual files. The query result data is displayed with a plurality of labels as specified in the configuration file. Edits can be performed by querying a collection of individual files using the configuration file, editing a portion of the query result, and transmitting only the edited information for storage back into a data repository.

  • Publication number: 20090077532
    Abstract: Systems and methods for providing generic post-generation annotation inference for verification of auto-generated code by automatically inferring safety annotations used to prove software safety. The inferred logical annotations are obtained by taking into account code patterns and safety requirements. The locations for inserting the annotations in the auto-generated code are obtained by using the code patterns to produce a flow graph of the result sensitive variables and the paths to all their corresponding definitions. The verification is customized to reduce unwarranted warnings by imposing no inherent restriction on the precision. A detailed report of verification of the auto-generated code is generated to permit independent verification and validation by a third party. The method operates independently from a model used to generate the code or internal templates of the code generator. The system may use untrusted components for inferring annotations and annotating the code.

  • Patent number: 6743632
    Abstract: Centrifugal analyzer and method for staining biological or non-biological samples in microgravity, wherein the method utilizes an increase in weight of a fluid sample as a function of g-load, to overcome cohesive and frictional forces from preventing its movement in a preselected direction. Apparatus is characterized by plural specimen reservoirs and channels in a slide, each channel being of differing cross-section, wherein respective samples are selectively dispensed, from the reservoirs in response to an imposed g-factor, precedent to sample staining. Within the method, one thus employs microscope slides which define channels, each being of a differing cross-section dimension relative to others. In combination therewith, centrifugal slide mounting apparatus controllably imposes g-vectors of differing magnitudes within a defined structure of the centrifuge such as a chip array.

  • Patent number: 6043893
    Abstract: Manually portable reflectance spectrometer and method of detection of absorption and reflection of light, wherein the visible and invisible (infrared) light is derived from LEDs. A phototransistor or photodiode measures the light reflected by the surface being measured, and a digital converter ADC translates the phototransistor's output into a digital format display. Three or more LEDs blue, aqua, green, yellow, orange, crimson, red and infrared provide a range of readings across the visible and infrared spectrum.

  • Patent number: 5113507
    Abstract: A computer memory includes K hard memory locations, hereinafter HMLs, each HML having M counters. A reference address element stores a reference address sequence of N bits. A data register stores data as a sequence of M integers. The memory has a processor system for determining a subset of HMLs to access for each reference address during read and write operations. For each HML, the processor system receives a subset of the reference address bits equal in number to q. The subset of reference address bits is chosen by selecting, for each HML, q integers between 1 and N as selected coordinates, hereinafter SCs, each SC corresponding to a bit position within the reference address, and for each SC for each HML, assigning a 0 or 1 as an assigned value for that SC. The processor system then stores the SCs and the assigned values and, for each of the SCs for each of the HMLs, compares the assigned value for the SC with the value of the corresponding bit in the reference address bits.

  • Patent number: 4690749
    Abstract: A method for eliminating or controlling electroosmosis and other zeta potential related phenomena in electrophoresis comprising conducting electrophoresis employing electrophoretic surfaces coated with covalently bound hydrophilic, neutral polymers is described. An electrophoretic chamber for eliminating or controlling electroosmosis and other zeta potential related phenomena in electrophoresis comprising electrophoretic surfaces coated with covalently bound hydrophilic, neutral polymers, is also disclosed as well as particles exhibiting controlled electrophoretic mobility. The method and electrophoretic chamber not only eliminate electroosmosis, but allow for specific control of electroosmosis. The coated electrophoretic surface is stable relative to prior art coatings and over a broad range of pH. The point of optical focus for accurate mobility measurements is increased from a narrow stationary level to the entire chamber, facilitating accurate measurements by mechanical means.
