  • Patent number: 10352596
    Abstract: An icemaker is mounted remotely from a freezer compartment. The icemaker includes an ice mold. A thermoelectric device is provided and includes a warm side and an opposite cold side. A flow pathway is connected in communication between the cold side of the thermoelectric device and the icemaker. In one aspect, a fan is operatively positioned to move air from the fresh food compartment across the warm side of the thermoelectric device and a pump moves fluid from the cold side of the thermoelectric device to the icemaker. Cold air, such as from a refrigerator compartment, may be used to dissipate heat from the warm side of the thermoelectric device for providing cold fluid to and for cooling the ice mold of the icemaker.

  • Patent number: 8705924
    Abstract: Various embodiments described include optical fiber designs and fabrication processes for ultra high numerical aperture optical fibers (UHNAF) having a numerical aperture (NA) of about 1. Various embodiments of UHNAF may have an NA greater than about 0.7, greater than about 0.8, greater than about 0.9, or greater than about 0.95. Embodiments of UHNAF may have a small core diameter and may have low transmission loss. Embodiments of UHNAF having a sufficiently small core diameter provide single mode operation. Some embodiments have a low V number, for example, less than 2.4 and large dispersion. Some embodiments of UHNAF have extremely large negative dispersion, for example, less than about ?300 ps/nm/km in some embodiments. Systems and apparatus using UHNAF are also disclosed.

  • Publication number: 20130294736
    Abstract: Various embodiments include photonic bandgap fibers (PBGF). Some PBGF embodiments have a hollow core (HC) and may have a square lattice (SQL). In various embodiments, SQL PBGF can have a cladding region including 2-10 layers of air-holes. In various embodiments, an HC SQL PBGF can be configured to provide a relative wavelength transmission window ??/?c larger than about 0.35 and a minimum transmission loss in a range from about 70 dB/km to about 0.1 dB/km. In some embodiments, the HC SQL PBGF can be a polarization maintaining fiber. Methods of fabricating PBGF are also disclosed along with some examples of fabricated fibers. Various applications of PBGF are also described.
