  • Loudspeaker with assembly and performance improvements
    Publication number: 20050111689
    Abstract: A loudspeaker that incorporates features for improvements in performance, and quality while reducing component and manufacturing costs. One embodiment details a plastic frame with integrally molded spider. Another embodiment details a spider molded with individual legs that provides better control of the restorative force characteristic. The spider may also incorporate more than one plane of lateral stiffness to improve the loudspeakers tendency for voice coil rocking. An additional embodiment details a frame with generic mounting edge that mates with a secondary mounting flange that includes product specific requirements. The frame and mounting flange are separated by an outer section of the diaphragm suspension annulus that serves as vibration isolation. An additional outer section of the annulus can serve as a gasket to the mounting structure.

  • Method and apparatus for detecting leaks in packaging
    Patent number: 6050133
    Abstract: A method and apparatus are directed to non-destructive testing for a leak in a sealed package having an interior chamber formed of a gas-permeable portion and a non-gas-permeable portion. A temporary barrier having an aperture is formed to the gas-permeable portion to temporarily seal the gas-permeable portion of the sealed package except at the aperture. A tracer gas is applied through the aperture at the gas-permeable portion, whereby the tracer gas enters into the interior chamber. The concentration of tracer gas is measured at the exterior of the sealed package, thereby testing for a leak in the sealed package.
