Abstract: A method and apparatus for hands free inductive charging of batteries for an electric vehicle is characterized by the use of a transformer having a primary coil connected with a charging station and a secondary coil connected with a vehicle. More particularly, the when the vehicle is parked adjacent to the charging station, the primary coil is displaced via a self alignment mechanism to position the primary coil adjacent to the secondary coil to maximize the inductive transfer of charging current to the secondary coil. The self alignment mechanism preferably utilizes feedback signals from the secondary coil to automatically displace the primary coil in three directions to position the primary coil for maximum efficiency of the transformer.

Abstract: This invention pertains to a device and method for making same. The device includes a substrate supporting optical waveguide, an overlay waveguide and a mode coupler for coupling between the substrate-supported and overlay waveguides. One embodiment includes a high-confinement overlay waveguide capable of low-loss bends with small bend radii, down to tens of microns, which represents two orders of magnitude improvement over prior art. One embodiment includes a feedback path enabled by the high-confinement waveguide, capable of implementing tunable ring resonator filters with free spectral ranges over 100 GHz and modulators with compact and interferometrically stable feedback paths. Another embodiment includes a periodically poled lithium niobate section capable of integrating wavelength conversion within a compact feedback path. Another embodiment includes an amplifier section, which may be incorporated in the feedback path.

Abstract: The reproducibility of preforms made by solution doping is significantly improved by adding an internal heat source, such as N2O, as a processing gas during the soot deposition process. The addition of the internal heat source gas results in forming a surface soot layer which exhibits a relatively uniform and consistent morphology. The improvement in the soot surface morphology results in improving the uniformity of the amount of solution dopant retained in the soot layer from preform to preform.

Abstract: The specification describes methods for the manufacture of very large optical fiber preforms wherein the core material is produced by MCVD. Previous limitations on preform size inherent in having the MCVD starting tube as part of the preform process are eliminated by removing the MCVD starting tube material from the collapsed MCVD rod by etching or mechanical grinding. Doped overcladding tubes are used to provide the outer segments of the refractive index profile thus making most effective use of the MCVD produced glass and allowing the production of significantly larger MCVD preforms than previously possible.

Abstract: Early stage detection of engine liquid cooling problems is provided with temperature, pressure and other sensors and associated logic circuits configured for detecting alarm conditions including below normal static coolant pressure coupled with an elevated coolant temperature, above normal static coolant pressure, below normal coolant pump pressure condition, coolant voids due to coolant loss or boiling, and external steam or liquid leakage from the cooling system. A gauge displays the difference between coolant pump output pressure and static coolant pressure.
