  • Patent number: 11931248
    Abstract: An IOL system includes a capsular ring having a concave exterior surface extending around its circumference that is configured, upon insertion into a capsular bag of a patient's eye, to engage an equatorial region of the capsular bag. The concave exterior surface extends between an anterior surface and a posterior surface of the capsular ring. A first one or more flaps are arranged on the anterior surface such that at least a portion of each of the first one or more flaps, upon insertion into the capsular bag of a patient's eye, engages an anterior portion of the capsular bag. Similarly, a second one or more flaps are arranged on the posterior surface such that at least a portion of each of the second one or more flaps, upon insertion into a capsular bag of a patient's eye, engages a posterior portion of the capsular bag.

  • Publication number: 20200308025
    Abstract: A UVC disinfection system is described where incoming fluid, such as water, is directed onto a transparent window in a vertical disinfection chamber. The incoming water is directed downward by a channel at an acute angle (e.g., 10-20 degrees) with respect to a central axis of the disinfection chamber and impinges on the window at an angle almost perpendicular to the window surface. One or more UVC LEDs are optically coupled to the window. The water impinging on the window becomes agitated due to the severe redirection and interaction with water already in the chamber. This randomizes (mixes) the water in the area where there is the highest UVC power. The UVC LEDs direct light along the central axis of the cylindrical chamber for maximum exposure of the water to the UVC light. Disinfection efficiency is therefore increased.

  • Patent number: 10490597
    Abstract: Embodiments of the invention include a first semiconductor layer grown over a growth substrate and a plurality of pixels grown on the first semiconductor layer, each pixel including an active layer disposed between an n-type region and a p-type region. Trenches isolate individual pixels and form at least one sidewall for each pixel. A first metal layer in direct contact with the p-type region is disposed on a top surface of each pixel. A second metal layer in direct contact with the n-type region is disposed on a bottom surface of a trench adjacent to each pixel. An insulating layer electrically isolating the first and second metal layers is disposed on the sidewall of each pixel and is substantially conformal to the sidewall.

  • Patent number: 10363327
    Abstract: A variety of applications for UV LEDs that are integrated into a system are described, where the UV light is used for disinfection of air or surfaces, or used to detect the scattering light by particles, or used for skin treatment. In one embodiment, a ceiling luminaire includes a sensor for detecting the presence of people in the room. The luminaire contains a first set of LEDs for generating white light, for illumination, and a second set of LEDs for generating UV light for disinfecting the room. When the sensor detects that no people are in the room, the system automatically controls the UV LEDs to turn on to disinfect the room. The white light LEDs may be independently controlled with a dimmer.
