Abstract:
An optical antenna assembly including multiple optical antenna elements, each of the optical antenna elements are arranged in a regular pattern and carried by a supporting body. The regular pattern of the plurality of optical antenna elements is nonuniform. Certain ones of the optical antenna elements are configured to respond to the one or more waves of light.
Abstract:
Various embodiments of methods and systems for designing and constructing displays from multiple light emitting elements are disclosed. Display elements having different light emitting and self-organizing characteristics may be used during display assembly.
Abstract:
A scanned beam display is operable to compensate for variations in apparent pixel brightness arising from variations in beam scanning velocity and/or pixel dwell times. A compensation circuit modifies pixel values according to their scanning velocity and/or dwell time.
Abstract:
Various embodiments of methods and systems for improving and enhancing vision are disclosed. Adjustable lenses or optical systems may be used to provide adaptive vision modification. In some embodiments, vision modification may be responsive to the current state of the user's visual system. Certain embodiments provide correction of the subject's near and far vision. Other embodiments provide enhancement of vision beyond the physiological ranges of focal length or magnification.
Abstract:
One embodiment of the subject matter of the present application, a method for identifying features of a model of an interior configuration of one or more three-dimensional objects within a three-dimensional interior space, includes including at least one respective identifier in an interior space item, the interior space item including an interior space cavity, the interior space cavity forming at least a part of a model of the three-dimensional interior space, and in one or more object items, the one or more object items forming at least a part of models of the one or more three-dimensional objects. Other embodiments are also disclosed.
Abstract:
A method for producing a model of an interior configuration of one or more three-dimensional objects within a three-dimensional interior space, including accepting interior space data representing at least a portion of the three-dimensional interior space; providing the interior space data to one or more rapid prototyping apparatuses to create an interior space item including a cavity, the cavity at least partially constituting a model of the three-dimensional interior space; accepting object data representing at least the one or more three-dimensional objects; and providing the object data to the one or more rapid prototyping apparatuses to create one or more object items, the one or more object items at least partially constituting models of the one or more three-dimensional objects. Other methods for producing such a model and an article are also disclosed.
Abstract:
A method and a system for determining a volume of a substance in a container where the method includes generating an excitation signal that creates an acoustic signal in the container, receiving the acoustic signal, and determining a volume of a substance in the container based at least in part on a signature of the acoustic signal.
Abstract:
A beam multiplier includes a beam-multiplying layer and an adjacent optical layer. The beam-multiplying layer is operable to generate output beamlets of light from an input beam of light, and the optical layer has an adjustable index of refraction. By switching the index of refraction of the optical layer between first and second values, one can switch the beam multiplier to a first state (e.g., “on”) where it generates the output beamlets of light, and can switch the beam multiplier to a second state (e.g., “off”) where it passes the input beam of light but does not generate the output beamlets. And by using the beam multiplier as an exit-pupil expander, one can switch the exit-pupil expander to a first state where it generates multiple exit-pupil images, and to a second state where it generates only a single exit-pupil image.
