  • Ultra low cost position and status monitoring using fiber optic delay lines
    Patent number: 6803998
    Abstract: Embodiments of the invention provide an improved method and apparatus for sensing position and/or status of an object. For one embodiment, a method generally includes illuminating the object with an optical pulse source and supplying a first optical pulse to a photo-detector, causing a resonant circuit formed by the photo-detector and an inductor to generate a resonant signal. The method also includes supplying at least a second optical pulse to the photo-detector causing a change in the resonant signal, wherein the second optical pulse is reflected from the object, monitoring the change in the resonant signal, and determining a position of the object based on the monitored change in the resonant signal. A velocity, direction of travel and/or acceleration of the object may also be determined from successive position measurements.

  • Gas knife cooling system
    Patent number: 5577658
    Abstract: A gas knife cooling system for reflow soldering cools soldered articles by impinging a gas flow directly on the articles and as a result uses less cooling gas. A heater is associated with the cooling system to remove flux deposits. The cooling system is installed in the cooling section of a reflow soldering apparatus and comprises at least one gas knife to direct a gas stream at soldered products passing through the cooling section on a conveyor. A heater is associated with the gas knife which is activated for predetermined cleaning cycles to heat the gas knife to a temperature above flux vaporization temperature of flux deposits from the soldered products.
