摘要:
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.

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.

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.
摘要:
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.

摘要:
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.
