  • Patent number: 7435010
    Abstract: Disclosed is a method of forming an optical monitoring or transmitting light guide and a resulting apparatus that begins by bonding a bundle of optical fibers together using an epoxy and polishing the distal end of the bundle of optical fibers to create an optical aperture. The ratio of fiber size to binder particulate size of the epoxy used in the bonding process is sufficient to maintain the integrity of the bundle of optical fibers during the polishing of the distal end. The method positions the bundle of optical fibers into a protective sheath and a connector. The coefficient of thermal expansion of the epoxy used in the bonding process matches that of the connector. Once assembled, the invention positions the connector through the opening in the surface of a device, such that the distal end of the bundle of optical fibers is either recessed in, substantially flush with, or extends from the surface of the device through which the connector extends, depending on field-of-view requirements.

  • Patent number: 6737785
    Abstract: An electric machine includes a stator with a plurality of circumferentially-spaced stator segment assemblies. A rotor rotates relative to the stator and defines an airgap between an outer diameter of the rotor and the inner diameter of the stator. Each stator segment assembly includes a stator segment core, an endcap that is attached to the stator segment core, and winding wire that is wound around the endcap and the stator segment core. The endcap provides first and second axial mating surfaces. The endcaps provide first and second circumferential surfaces on opposite axial ends thereof. First and second annular seals engage the first and second circumferential surfaces to provide circumferential seals at opposite axial ends of the stator. The annular seals, the axial seals and the circumferential seals prevent the entry of debris into the airgap.

  • Patent number: 6263034
    Abstract: A fully digital filter jitter reduction circuit for attenuating jitter transfer in a digital communication system or subsystem includes a digital filter which attenuates jitter transfer within a bandwidth of the filter. A single synthesized clock, from which all other required clocks are created by precessing or phase shifting with respect to the synthesized clock, is utilized to create a reduced jitter output clock. Under the control of the digital filter, the reduced jitter output clock operates an output data latch such that the output data latch performs the function of an elastic buffer. Several stages of the digital filter jitter reduction circuit can be implemented in cascade to further reduce jitter. Since jitter attenuation is a function of the input jitter amplitude, the digital filter is nonlinear in nature.

  • Patent number: H716
    Abstract: In a system using a touch panel type of overlay on a cathode ray tube screen wherein multiple areas for user selection are presented on the tube screen, erroneous touch selection of displayed areas on the tube because of parallax-induced offset is avoided by assigning a guard band around each display area. The width of the band is designed to correlate to the amount of parallax error associated with the combined tube and overlay touch screen environment.
