  • Patent number: 8008930
    Abstract: A test structure for polymer characterization over a wide frequency range, temperature range and under an applied DC electric field is disclosed. A high resistivity silicon substrate is topped by an adhesion layer. A polymer thin-film is deposited on a patterned metal1 layer which is deposited on top of the adhesion layer. A top metal2 layer is deposited on the polymer thin-film and patterned to form a CPW transmission line. A single bias voltage is applied to the center conductor of the CPW transmission line on metal2 and influences dielectric properties of the polymer. The dielectric permittivity and the loss-tangent of the polymer can be derived as functions of electric field and temperature by measuring the swept frequency scattering parameters and matching the experimental frequency response to the modeled frequency response. The electrical conductance properties of the polymer can be accurately characterized using the test structure over a wide temperature range.

    Abstract: An inductor structure comprising a substrate and a planar conductor structure on a surface of the substrate, and methods for fabricating an inductor structure. The planar conductor structure may comprise a vertical stack of three or more multilayer films. Each multilayer film may comprise a first layer of a first metal, defining a first vertical thickness, and a second layer of a second metal, defining a second vertical thickness. The metals and thicknesses are chosen such that the inductor exhibits a negative electrical self-inductance when an electrical signal is transmitted from a first contact point to a second contact point.

  • Patent number: 7922975
    Abstract: A resonant sensor for detecting a specific environmental analyte is presented. The resonant sensor comprises a top conductive layer of two ground conductors and a center signal line, a bottom conductive layer of two ground lines shunted together by a shunt line and a sensing layer positioned between the top conductive layer and the bottom conductive layer. A capacitor is created by the overlap of the center signal line of the top conductive layer and the shunt line of the bottom conductive layer. Electrical properties of the sensing layer change in response to binding the specific environmental analyte with the sensing layer. The sensing layer can be an electro-optic polymer. Nanoparticles or carbon nanotubes can be dispersed within the sensing layer to bind with the specific environmental analyte. An integrated antenna can be incorporated into to sensor to receive radio frequencies for wireless, passive sensing.

  • Patent number: 7904202
    Abstract: A method and system to provide improved accuracies in multi jointed robots through kinematic robot model parameters determination are disclosed. The present invention calibrates multi-jointed robots by using the chain rule for differentiation in the Jacobian derivation for variations in calculated poses of reference points of a reference object as a function of variations in robot model parameters. The present invention also uses two such reference objects and the known distance therebetween to establish a length scale, thus avoiding the need to know one link length of the robot. In addition, the present invention makes use of iterative methods to find the optimum solution for improved accuracy of the resultant model parameters. Furthermore, the present invention provides for determination of the end joint parameters of the robot, including parameters defining the tool attachment mechanism frame, which allows for interchange of tools without subsequent calibration.

  • Publication number: 20110024717
    Abstract: A method and system for the preferential growth of semiconducting vertically-aligned single-walled carbon nanotubes (VA-SWNTs) is provided. The method combines the use of plasma-enhanced chemical vapor deposition at low pressure with rapid heating. The method provides a high yield of up to approximately 96% semiconducting SWNTs in the VA-SWNT array. The as-synthesized semiconducting SWNTs can be used directly for fabricating field effect transistor (FET) devices without the need for any post-synthesis purification or separation.

  • Patent number: 7833331
    Abstract: Corrosion-inhibiting pigments based on cobalt are described that contain a trivalent or tetravalent cobalt/valence stabilizer complex. An inorganic or organic material is used to stabilize the trivalent or tetravalent cobalt ion to form a compound that is sparingly soluble in water. Specific stabilizers are chosen to control the release rate of trivalent or tetravalent cobalt during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Cobalt/valence stabilizer combinations are chosen based on the well-founded principles of cobalt coordination chemistry. Many cobalt-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium systems.

  • Patent number: 7789958
    Abstract: Corrosion-inhibiting pigments based on manganese are described that contain a trivalent or tetravalent manganese/valence stabilizer complex. An inorganic or organic material is used to stabilize the trivalent or tetravalent manganese ion to form a compound that is sparingly soluble, exhibits low solubility, or is insoluble in water, depending upon the intended usage. Specific stabilizers are chosen to control the release rate of trivalent or tetravalent manganese during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Manganese/valence stabilizer combinations are chosen based on the well-founded principles of manganese coordination chemistry. Many manganese-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium or tetravalent lead systems.
