Abstract: Some embodiments provide a lens including a lens body and an optical filter configured to attenuate visible light in certain spectral bands. At least some of the spectral bands can include spectral features that tend to substantially increase the colorfulness, clarity, and/or vividness of a scene. In certain embodiments, eyewear incorporates an optical filter that enhances chroma within one or more spectral bands. In some embodiments, a wearer of the eyewear can perceive the increase in chroma when viewing at least certain types of scenes.

Abstract: Embodiments comprise a lens for an eyewear. The lens comprises a portion of a conical surface configured to be located in the path of a wearer's field of vision. The portion of the conical surface has a first side edge and a second side edge. The portion of the conical surface extends arcuately from the first side edge to the second side edge. The portion of the conical surface has an upper edge and a lower edge. The portion of the conical surface extends from the upper edge to the lower edge. A rate of change of a lens normal from the upper edge to the lower edge is constant. The lens normal is measured along an axis that intersects the conical surface at a pupillary distance.

Abstract: Some embodiments provide a lens including a lens body and an optical filter configured to attenuate visible light in a plurality of spectral bands. Each of the plurality of spectral bands can include an absorptance peak with a spectral bandwidth, a maximum absorptance, and an integrated absorptance peak area within the spectral bandwidth. An attenuation factor obtained by dividing the integrated absorptance peak area within the spectral bandwidth by the spectral bandwidth of the absorptance peak can be greater than or equal to about 0.8 for the absorptance peak in each of the plurality of spectral bands.

Abstract: The present disclosure relates to a high transmittance eyewear. The high transmittance eyewear can include a lens with a chroma enhancement filter. The lens can have a front surface and a rear surface. The high transmittance eyewear can further include a transmittance enhancement layer disposed over the front surface of the lens. The high transmittance eyewear that includes the transmittance enhancement layer and the chroma enhancement filter can provide a high optical transparency (e.g., a high optical transmittance) for the wearer for an indoor or a driving use while maintaining a chroma enhancement capability provided by the chroma enhancement filter.

Abstract: Disclosed herein are system, method, and computer readable media embodiments for controlling the capture and sharing of an image and/or video of a subject by a third party device. In some embodiments, an electronically-enabled wearable device worn by a subject may detect an active, nearby camera-capable device. Identification information for a user associated with the camera-capable device may be requested and received from the camera-capable device. An authorization level may then be determined for the user based on the identification information. In some embodiments, a camera control signal and/or authorization metadata may be generated based on the authorization level of the user and sent to the camera-capable device, for transmission to the camera-capable device.

Abstract: Embodiments disclosed herein include eyewear that provides controlled variable light attenuation and color enhancement based on an input received from a user, a sensor and/or a signal from a control circuit. In some embodiments, the eyewear includes an optical filter system with two or more defined filter states that are adapted to improve color vision in different environments. The optical filter system can be incorporated into a lens having any desired curvature, including, for example, cylindrical, spherical or toroidal. The lens can include one or more functional components. Examples of functional components include color enhancement filters, chroma enhancement filters, a laser attenuation filter, electrochromic filters, photoelectrochromic filters, variable attenuation filters, anti-reflection coatings, interference stacks, hard coatings, flash mirrors, anti-static coatings, anti-fog coatings, other functional layers, or a combination of functional layers.

Abstract: Some embodiments provide a visor brim including a visor brim body and an optical filter configured to attenuate visible light in certain spectral bands. At least some of the spectral bands can include spectral features that tend to substantially increase the colorfulness, clarity, and/or vividness of a scene. In certain embodiments, headgear incorporates an optical filter that enhances chroma within one or more spectral bands. In some embodiments, a wearer of the headgear can perceive the increase in chroma when viewing at least certain types of scenes. In some embodiments, a wearer can combine chroma-enhancing headgear and chroma-enhancing eyewear to view complementary chroma enhancement.

Abstract: A fish model to replace the use of live fish in hydroelectric studies is provided. The fish model is cast from ballistic gel to include the density, dimensions, and weight distribution of a selected species of living fish. The fish model is formed by additively manufacturing a mold based on a three-dimensional scan of an actual fish. The mold is then used to mass produce fish models for force measurement testing at various blade speeds, thickness, and impact angles. Each fish model includes a surrogate skin and an internal sensor for strike force measurements. Optional additional sensors include strain gauges, temperature probes, pressure probes, and load sensors, for example.
