摘要:
Techniques and assemblies for steering light rays are described. An electro-optic prism configured to provide controllable steering of solar rays includes a first electrode including multiple substantially parallel linear electrodes positioned on a first substrate and a reference electrode positioned on a second substrate. An electro-optic material is positioned between the first electrode and the reference electrode. In one implementation, a wavelength selective filter is in optical communication with the electro-optic prism. The wavelength selective filter is configured to substantially eliminate selected wavelengths from solar rays before the solar rays are received by the electro-optic prism. In another implementation, a chemical compound is configured in the assembly to convert ultra-violet photons included in the solar rays into visible photons.

An electro-active spectacle lens is disclosed. The spectacle lens comprises a first substrate having a first outer region and first inner region, a first electrode layer disposed adjacent to the first inner region, the first electrode layer including an outer electrode region having a first conductivity and an inner electrode region having a second conductivity, the first conductivity being greater than the second conductivity, a second substrate having a second outer region and second inner region, a second electrode layer disposed adjacent to the second inner region, the second electrode layer having a third conductivity, and an electro-active cell disposed between the first electrode layer and the second electrode layer, the electro-active cell containing an electro-active material. The first outer region and second outer region are configurable for fitting the spectacle lens within a lens frame without altering the electro-active cell.
摘要:
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.

A range finder device for use with a controller in an optical system is disclosed in accordance with one embodiment of the invention. The range finder device comprises a transmitter to produce a first beam of non-visible radiation for intersecting a perceived object, and a receiver to detect non-visible radiation reflected from that object. The controller determines a viewing distance of the perceived object based on signals received from the transmitter and receiver. A method of controlling an optical lens system comprises utilizing a range finder device to determine a viewing distance of an object perceived through an electro-active lens and adjusting a focal length of a portion of the lens based on the viewing distance. An optical lens system comprises an electro-active lens and a controller to adjust a focal length of at least a portion of the electro-active lens based on a signal from a range finder device.

An advanced floor mat is disclosed. In an embodiment of the present invention, the floor mat includes a cleanable portion. The floor mat may also include a water dissipation component, a water absorbing component, a cushioning component, customized graphics, a transparent cleanable portion, a tacky surface on the cleanable portion, an antibacterial composition, an antifungal composition, and a fragrance. The cleanable portion may be erodible and may include a plurality of cleanable reusable layers. If a tacky surface is included in the floor mat, an anti-slip feature may be associated with the tacky surface to help prevent slipping on a possibly wet tacky surface. Additionally, a sensor system may be included in the floor mat to assist a user in identifying when the floor mat may require cleaning.
摘要:
A device is disclosed for cleaning a surface. In one embodiment, the device includes a sheet having at least one tacky surface and a plurality of rollers in contact with said sheet, said plurality of rollers, in an operative embodiment, maintaining contact between said tacky surface and the surface to be cleaned.

Embodiments of the present invention relate to a multifocal lens having a diffractive optical power region and a progressive optical power region. Embodiments of the present invention provide for the proper alignment and positioning of each of these regions, the amount of optical power provided by each of the regions, the optical design of the progressive optical power region, and the size and shape of each of the regions. The combination of these design parameters allows for an optical design having less unwanted astigmatism and distortion as well as both a wider channel width and a shorter channel length compared to conventional PALs. Embodiments of the present invention may also provide a new, inventive far-intermediate distance zone and may further provide for increased vertical stability of vision within a zone of the lens.

A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.
