Abstract: Structures for a thermo-optic phase shifter and methods of forming such structures. The structure comprises a waveguide structure including a waveguide core. The structure further comprises a silicide layer, a first dielectric layer arranged in a lateral direction between the silicide layer and the waveguide core, and a second dielectric layer positioned over the waveguide core, the silicide layer, and the first dielectric layer. The first dielectric layer comprises a first material having a first thermal conductivity, and the second dielectric layer comprises a second material having a second thermal conductivity that is less than the first thermal conductivity.

Abstract: An avian distractor device includes a clamp having a pair of jaws attached to a hinge and biased via a plurality of springs into a closed position, and a locking member disposed in communication with the pair of jaws to rigidly hold a conductor of different sizes under a force generated by the plurality of springs. A spherical diverter is provided and is rotatably attached to the hinge and the clamp. A reflective surface encircles a central portion of the spherical diverter to enhance visibility of the device to wildlife. A plurality of dimples are formed on an external surface of the spherical diverter to reduce a drag force on the device.

Abstract: An attachment clip for an overland distribution line cover includes an eye receiving an electrical line, an opening for insertion of the electrical line, an intermediate section connecting the opening with the eye, and a snap-fit member fixing the attachment clip to the overland distribution line cover.

Abstract: Methods and apparatus are provided for monitoring crimping of metal end fittings onto electrically insulating core rods. The force and/or pressure applied to the metal end fittings by crimping jaws are monitored during crimping. The distance travelled by the crimping jaws is also measured during crimping. A change is detected in the relationship between the force and/or pressure and the distance travelled by the crimping jaws, such as by detecting a non-increasing force and/or pressure with an increasing distance. The methods and apparatus of the present invention may provide for detection and/or prediction of cracks in the electrically insulating core rods to improve the crimping process.
