    摘要: Electromagnetic radiation detecting and sensing systems using carbon nanotube fabrics and methods of making the same are provided. In certain embodiments of the invention, an electromagnetic radiation detector includes a substrate, a nanotube fabric disposed on the substrate, the nanotube fabric comprising a non-woven network of nanotubes, and first and second conductive terminals, each in electrical communication with the nanotube fabric, the first and second conductive terminals disposed in space relation to one another. Nanotube fabrics may be tuned to be sensitive to a predetermined range of electromagnetic radiation such that exposure to the electromagnetic radiation induces a change in impedance between the first and second conductive terminals. The detectors include microbolometers, themistors and resistive thermal sensors, each constructed with nanotube fabric. Nanotube fabric detector arrays may be formed for broad-range electromagnetic radiation detecting. Methods for making nanotube fabric detectors, arrays, microbolometers, thermistors and resistive thermal sensors are each described.

    摘要: Multiple stage ranging circuitry for a measuring circuit includes a first ranging circuit that selectively amplifies an input signal by respective amounts according to the magnitude of the input signal thereto, and a second ranging circuit coupled to the output of the first ranging circuit selectively amplifies the output signal from the first ranging circuit by a respective amount according to the magnitude of that output signal to provide a measured output. The multiple stage ranging circuitry increases dynamic range and provides for high speed measurements over that dynamic range.A method of ranging for high speed signal measurements over a wide dynamic range includes directing an input signal to a first ranging stage that responds at one speed to set ranging over a relatively wide variation in input signal magnitudes, and directing the output signal from the first ranging stage to a second ranging stage responsive at a second speed faster than the one speed to set ranging over a relatively narrower range of signal magnitudes to provide for signal measurement.

    摘要: A higher capacity nanoporous silicon thin film structure with alternating layers of silicon nanoparticles and carbon nanotube nonaligned will result in an anode for lithium ion batteries. This nanocomposite structure will increase the specific capacity to 3500 mAh/g-1 versus 350 mAh/g-1 for state of the art lithium batteries. Charge/discharge cycles of 5000 with a maximum of 15% loss are also achievable. This is due to the silicon nanocomposites capability to accommodate the mechanical expansion of the lithiated silicon species. Reliability defects such as copper cracking and delamination will be minimized using a barrier/adhesion metal layer. This will also reduce copper dendrite formation. Particle cracking and lithium plating will also be reduced by using the silicon based nanocomposite. The silicon nanocomposite can be fabricated using off the shelf deposition techniques minimizing transition to high rate production and recurring manufacturing product costs.

    摘要: An miniature integrating sphere has a spherical volume with walls of a material for reflecting light, a light inlet and a light outlet. The light inlet is offset from a diameter axis of the spherical volume and the light inlet and light outlet are offset at non-perpendicular and non-parallel relation to each other. The light inlet is molded or milled to a shape conforming to the shape of the cone of light provided by a fiber optic device as an input to the integrating sphere. A number of miniature integrating spheres may be used respectively in plural channels of an optical measurement instrument.

    摘要: A range selection circuit (13), including a logarithmic amplifier (23) and output circuitry (25) associated therewith, is configured to directly drive linear ranging circuitry for measurement circuitry (12) in an optical power meter (10) to measure signals that vary over a wide range of, for example, from about −7 dB to about −45 dB. This allows the optical power meter to change ranges as fast as one (1) times the hardware settling time. The range selection circuitry is in parallel with the measurement circuitry, which allows ranging to happen in real time.
