  • Patent number: 10228110
    Abstract: An handheld illuminating device with orb-shaped lens for enhancing forward and lateral visibility including a flashlight having at least one light source that emits light rays through an orb-shaped lens. The orb-shaped lens is semi-spherical and adapted to disperse the light rays through a substantially 270° arc of uniform light for illuminating more than one area around the user, diffusing the light rays to soften the illumination from the light source, and eliminates shadows that are inherent in flat or curvilinear lenses. A reflector reflects light rays from the light source to the orb-shaped lens. A power supply powers the light source. A switch regulates power and intensity of the light source. A transparent cover protects the orb-shaped lens from physical damage.

  • Patent number: 10072822
    Abstract: Disclosed are examples of optical/electrical devices including a variable TIR lens assembly having a transducer, an optical lens and an electrowetting cell coupled to an exterior wall of the lens. The electrowetting cell contains two immiscible liquids having different optical and electrical properties. One liquid has a high index of refraction, and the other liquid has a low index of refraction. At least one liquid is electrically conductive. A signal causes the high index of refraction and the low index of refraction liquids to assume various positions within the electrowetting cell along the exterior wall. The properties of the optical lens, e.g. its total internal reflectivity, change depending upon the position of the respective liquids along the exterior wall. The light characteristics of the assembly change to produce a light beam over a range of light beam outputs or a field of view over a range of fields of view.
