  • Patent number: 7619809
    Abstract: A mirror assembly including an active lens and a reflective surface. The mirror assembly may change its refractive index when a voltage is applied to the active lens, thereby changing the field of view in the lens. Exemplary applications include a blind spot system in a motor vehicle, in which, upon sensing another vehicle in a driver's blind spot, the mirror assembly changes the driver's field of view to include the blind spot. Additional applications include a magnifying mirror for shaving or applying cosmetics.

  • Publication number: 20090279050
    Abstract: A lens is presented in which the lens includes a substrate and an electrode layer. The electrode layer is positioned upon the substrate. The electrode layer has radially alternating rings of electrodes and resistive material. When voltage is applied across two adjacent electrodes the profile of the electric field therebetween is linear. When voltage is applied to the rings of electrodes, the optical phase profile of the lens closely approximates the optical phase of ideal spherical aberration correction.

  • Publication number: 20090272817
    Abstract: Methods and apparatus for reducing the intensity of hurricanes are described herein. A method may include positioning a fleet of submersibles in an area of ocean through which at least a portion of a hurricane's central core will pass within a predetermined amount of time. The submersibles are maneuvered to a depth greater than a depth of a thermocline in this area of ocean. The submersibles maintain their station and depth for a finite amount of time, during which they may release a gas to form bubble plumes which rise toward the ocean's surface. The bubble plumes entrain and upwell cold sub-thermocline water toward the surface of the ocean to cool the surface of the ocean. The cooled ocean surface reduces the intensity of the hurricane whose portion of central core passes through the cooled area.

  • Publication number: 20090250094
    Abstract: Systems and techniques for light ray concentration. In one aspect, a solar concentration assembly includes an array of light focusing elements and an array of photovoltaic devices positioned beneath the array of light focusing elements. The arrays of light focusing elements and photovoltaic devices are spaced from one another and configured to concentrate solar rays incident on the light focusing elements to the photovoltaic elements, such that solar ray communication is maintained as an angle of the assembly relative to the sun is altered by movement of the sun during a day and wherein the angle is an oblique angle for the majority of the day.

  • Patent number: 7588332
    Abstract: A lens system and optical devices that provide enhanced vision correction are disclosed. The lens system includes an electro-active layer that provides correction of at least one higher order aberration. The higher order correction changes dynamically based on a user of the lens system's needs, such as a change by the user's gaze distance, pupil size, or changes in tear film following blinking, among others. Optical devices are also described that use these and other lens systems to provide correction of higher order aberrations. An optical guide is also described that guides the user's line of sight to see through a lens region having a correction for a higher order aberration.

  • Patent number: 7533993
    Abstract: An electro-active phoropter and a method of using the electro-active phoropter to measure a patient's vision prescription is disclosed. The electro-active phoropter includes a series of individually addressable electro-active lenses. The lenses have either a positive or negative optical power when an electrical potential is applied across the lens and a neutral optical power when no electrical potential is applied across the lens. Each lens provides an optical power that is part of a net optical power of the series of lenses when a patient views through the phoropter. The optical power of the phoropter can be incrementally adjusted by changing the distribution of the electrical potential across the different lenses of the series to provide increasing or decreasing optical power until a patient achieves a desired level of clarity and a vision prescription has been determined.

  • Publication number: 20090015785
    Abstract: A lens system is presented having a lens having an electro-active element, a sensor for sensing a change in ambient light, a controller in operative communication with the sensor, and a plurality of electrode rings electrically connected to the controller. The electrode rings may be concentric. The controller applies a voltage to the plurality of electrode rings when the sensor senses a change in ambient light. The application of voltage causes a change in the refractive index of the electro-active element for correcting a spherical aberration of the eye due to the sensed change in ambient light.
