  • Fiber Optic Cylindrical Diffuser
    A fiber optic, cylindrical, light diffuser for medical use includes an unclad distal fiber end where the exposed core end has a conical shape. The core end is enclosed by a sleeve which contacts the clad portion of the fiber only and defines a closed chamber with the distal end of the fiber
  • Analysis of Undiffused and Diffused Light on Stainless Steel
    An analysis of why stainless steel appears to have a large number of imperfections under undiffused light but the same steel surface under diffused light does not reveals that diffused light has less variability in the intensity of the reflected light. This is shown through analysis of pictures
  • Operating Principles for Photoelectric Sensors
    These sensors use light sensitive elements to detect objects and are made up of an emitter (light source) and a receiver. Four types of photoelectric sensors are available. Direct Reflection (Diffused) - emitter and receiver are housed together and use the light reflected directly off the object
  • FOOD INSPECTION: Automated system inspects dates at high speed
    Because the surfaces of the dates vary in both topology and color, even and uniform white lighting is needed to illuminate them. Four MB-DL406 MetaBright diffuse dome lights 4 in. in diameter from Metaphase (Bensalem, PA, USA) are installed on each machine. Coupled to each light, a 1280 × 960-pixel
  • Vision Systems Design - Imaging the Tube
    Solyndra manufactures tubular solar modules. for rooftop installations. A copper indium. gallium selenide (CIGS) thin-film material. is applied to the inside of a glass tube so that. the module can collect light from virtually any. direction-direct, diffuse, or reflected. The key. components
  • Smart Computing Article - frequency hopping spread spectrum (FHSS) to FTP
    range in the electromagnetic spectrum, to transmit data. The drawback is that IR systems must be either line-of-sight or diffused because IR light cannot go through dense objects. A third technology employed in many wireless LANs is spread spectrum, a wideband (multiple-frequency) transmission system
  • Semiconductor: Dissolved Ozone Measurement in Semiconductor Ultrapure Water Systems
    product yields. Ozonation typically occurs prior to the UPW storage tank, in the distribution return piping, or may be diffused directly into the storage vessel itself. Levels are typically maintained in the range 5 to 50 ppb but then must be eliminated using ozone destructing UV light. Ozone
  • Fast molecular tracking maps nanoscale dynamics of plasma membrane lipids
    molecules through a spot of excitation light allows the sequential localization and thus spatio-temporal tracking of the molecule if its fluorescence is collected on at least three separate point detectors arranged in close proximity. We show two-dimensional trajectories of individual, small organic
  • MSilica Nanoparticles Treated by Cold Atmospheric-Pressure Plasmas Improve the Dielectric Performance of Organic-Inorganic Nanocomposites
    motion were. commensurate, rapid mixing was observed. The rectangular mixing chambers were. found to be more efficient than the circular chambers. This approach shows potential for. mixing low diffusivity biological samples, which is a very challenging problem in laminar. flows at small scales
