Abstract: Aspects of the present invention provide an electro-active lens and method for manufacturing the same that encapsulates liquid crystal using solid transparent optical material using an improved liquid crystal seal feature. The seal feature greatly reduces the visibility of the liquid crystal seal feature in an assembled electro-active lens. The seal feature is also structurally robust such that the electro-active lens can be processed to fit a spectacle frame without disturbing containment of the liquid crystal and without disrupting electrical connectivity to the lens used to alter the refractive index of the liquid crystal, thereby ensuring fabrication of a commercially viable electro-active lens.

Abstract: The current application is directed to methods and systems for designing and configuring web-site testing and analysis. In certain implementations, a testing service collects customer page-access and conversion information on behalf of a web site. The testing service is straightforwardly accessed and configured, through a web-site-based graphical user interface, and is virtually incorporated into the web site.

Abstract: Embodiments of the present invention are directed to methods and systems for testing web sites and web servers. In discussed embodiments of the present invention, a third-party testing service collects page-access and conversion information on behalf of a web site. The third-party testing service is straightforwardly configured through a user interface and is engaged for real-time, live statistics collection by means of simple modifications of HTML files served or provided to users by a web site.

Abstract: Aspects of the present invention provide multi-focal electro-active lenses having one or more multi-focal electro-active inserts. The electro-active inserts can provide multiple optical power regions each capable of providing a desired optical power. An electro-active power region of the insert is capable of providing a variable optical power upon application of an electrical signal such as a time-varying voltage waveform. Electro-active inserts can be fabricated from any type of material and can be inserted into any type of bulk lens material. The electro-active inserts can be thin and flexible and can function independently of other optical components of the overall electro-active lens. Consequently, the electro-active inserts can be fabricated according to a uniform design using uniform materials, independent of the supplementing portions of the final lens. Index matching layers of the present invention can be used to reduce reflection losses between bulk lens material and electro-active insert interfaces.

Abstract: A bearing assembly particularly suitable for the rotor arrangement of an electrical motor or generator includes a bearing located in a housing. The bearing has an inner race, an outer race, and a plurality of ball bearings between the inner and outer races. A portion of the housing is made up of a deformable flexible wall which permits the housing to conform to the shape of the outer race member, rather than forcing the outer race to conform to the shape of the housing, as was experienced hitherto.

Abstract: A rotor assembly for an electronic machine such as a motor includes a rotor on a shaft having a bearing at each end portion, the bearings being arranged to rotatably support the rotor and shaft. The assembly further includes a balancing member, from which material may be removed for balancing the rotor assembly. The balancing member is located in a predetermined position and orientation with respect to the rotor. The balancing member includes an encoder disk, arranged to permit positioning of the rotor with respect to a stator. The provision of a balancing member having an integral encoder disk facilitates the manufacture of the rotor assembly. As the balancing member is located in a predetermined position, the encoder automatically assumes a predetermined position and hence the position of the rotor can be determined with certainty.

Abstract: A metal-semiconductor field-effect transistor is formed by providing a blanket layer of the same conductivity type as the semiconductor body, with field oxide subsequently being grown, and with a region of opposite conductivity type being formed to extend partially under the field oxide, the initial blanket layer acting as the field implant region of the field-effect transistor.

Abstract: A process for forming the field dielectric regions in semiconductor structures without encroaching upon device areas includes the steps of forming an insulating layer on a surface of a semiconductor substrate, forming regions of selected material on the surface of said insulating layer, converting said regions of selected material to insulating material, and removing the insulating layer from the surface of the semiconductor substrate except where the insulating material overlies the insulating layer. Active and/or passive electronic devices may then be formed in the exposed regions of said semiconductor substrate using well known semiconductor processing technology. The combined insulating layer and insulating material will prevent field inversion from occuring in all of those regions of the semiconductor substrate on which the insulating layer and the insulating material are disposed.
