  • Patent number: 9753185
    Abstract: A metamaterial control device is provided for controlling electromagnetic radiation. The device uses a light-guide film (LGF), with the LGF being capable of receiving light emission along an edge. The device includes a substrate disposed on a non-edges surface of the LGF, electromagnetic cellular structures that are controllable, and an optically sensitive component within some or all cells. The substrate is composed of metamaterial and having an interface that corresponds to an extractor on the non-edge surface for scattering light therefrom. Alternatively, the substrate can constitute the LGF itself. The cell structure is disposed around the extractor. The optically sensitive component is disposed to cover the extractor. The component changes in response to receiving the light from the extractor and changes in response to intensity of the light.

  • Patent number: 8784704
    Abstract: A material is provided for switching dielectric constant between distinct first and second values responsive to electromagnetic radiation having a specified energy. The material includes a medium transparent to the radiation and a plurality of particulates. Each particulate has a dipole that assumes one of distinct first and second parameters that correspond to the first and second values. The particulates are suspended within the medium. The parameters are either dipole span or charge strength. The dipole of each particulate sets to the first parameter by default and sets to the second parameter in response to the radiation. The particulates can be composed from undoped semi-insulating gallium arsenide. The medium can be polymethylmethacrylate, for example.

  • Patent number: 8399817
    Abstract: A micro designator dart engages a target to allow for designation and tracking of the target by transmitting a radio-frequency identification code. The housing of the micro designator dart is configured to enclose its components and deform upon impact with a target to allow a target-engaging member to physically attach the micro designator dart to the target. Also upon impact with the target, an impact-sensitive triggering mechanism in the micro designator dart activates a power source, causing a transmitter to send a predetermined coded infrared signal to the seeker unit of a precision guided munitions system. The micro designator dart may also include a self-destruct device.

  • Patent number: 8311373
    Abstract: A detector is provided for sampling and identifying a material, such as a medium in which the detector is disposed. The detector includes an annular photonic crystal fiber, first and second electrodes, an electrical power supply, an illumination source and an analyzer. The fiber has opposite longitudinal ends, surrounds a center core tube and includes fused capillary tubes. The electrodes are disposed between the fiber's longitudinal ends. The electrical power supply connects between the electrodes. The illumination source emits light into the core tube from one of the opposite ends. The analyzer for compares an emission pattern from light transverse to the fiber against an established pattern, and indicates match in response to correspondence between the patterns. The annular structure has a two-dimensional optical photonic band-gap. The analyzer monitors the emission pattern by optical frequency domain reflectometry or optical time domain reflectometry.

  • Patent number: 7947287
    Abstract: This invention is related to the Molecular Pharmacology field and especially to the development of peptides useful for treating epithelial tumors and mainly those associated to oncogenic types of HPVs. The main objective of this invention is to identify peptides whose structure permits to block the Casein Kinase II (CKII) phosphorylation domain by direct interaction with such a site. In the present invention it is shown eleven cyclic peptides with different aminoacid sequences which inhibit the CKII phosphorylation in vitro, exhibit cytotoxicity on HPV-16 transformed cells (CaSki) and also increase the sensitivity of these cells to the cytostatic effect of interferon (IFN). Furthermore, the invention relates to the use of these peptides conjugated or fused to other peptides and chemical compounds which penetrates into cells as well as with the use of both peptide and chemical mimetic molecules.

  • Patent number: 7864394
    Abstract: A dynamically variable lens is made from actively tunable electromagnetic metamaterial cells. The lens operates on electromagnetic radiation including: radio frequency waves, microwaves, teraherz waves, near infrared waves, infrared waves and visible waves. The focal length of the lens is changed at a selected frequency. In the alternative, the frequency of radiation operated on is changed as a function of time. A third alternative provides precise control of the index of refraction of the lens. The index of refraction is varied progressively across the lens from one edge to the opposite edge causing the radiation to be directed at an angle.

  • Publication number: 20100151566
    Abstract: The present invention deals with recombinant polypeptide molecules related to antibodies, that specifically recognize the human Vascular Endothelial Growth Factor A (VEGF-A), and interfere with its in vitro stimulatory effects and pro-angiogenic activity in vivo. These recombinant polypeptide molecules affect proliferation of human endothelial cells in vitro, subcutaneous angiogenesis in mice induced by Matrigel pellets that contain VEGF-A and the growth of human tumors transplanted in nude athymic mice. Several of these moleculas prevent choroideal neovascularization in a non human primate experimental model.
