The OLB is composed of an acrylic material that has been infused with an ultraviolet (UV) absorbing compound rendering it amenable to customized spatial modification (CSM) of its refractive index via the use of pulsed laser radiation (PLR). The CSM of refractive index eliminates the need for remote laboratory fabrication of a customized intraocular lens (IOL) for the patient. The OLB is retained within a secured lens container (SLC) providing for precise physical orientation of the OLB haptics and OLB lens structure with respect to the application of PLR to the OLB. The SLC contains a lens filler material (LFM) covering the OLB and is hermetically sealed after the OLB has been positioned within the SLC interior and prior to sterilization of the SLC+OLB combination.

  • Patent number: 10423274
    Abstract: Methods, device, and computer program product for mitigating pathogen transmission via a touch surface of a touch input device. Mitigation is accomplished through selective touch surface sterilization and through touchscreen user interface reorganization. The touch surface includes a pixel array for illuminating selected portions of the touch surface with ultraviolet light of a sterilization wavelength based upon the received touch inputs. The selective illumination may occur while receiving a touch input or after an accumulation of touch inputs have been received. The user interface may also be reorganized based on received touch inputs in order to locate user interface icons to lesser touched locations of the touch surface.

  • 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.

  • Patent number: 10245341
    Abstract: Disinfection methods and apparatuses are provided which generate pulses of germicidal light at a frequency greater than 20 Hz and project the pulses of light to surfaces at least 1.0 meter from the disinfection apparatus. The pulses of light comprise a pulse duration and an energy flux sufficient to generate a power flux between approximately 200 W/m2 and approximately 5000 W/m2 of ultraviolet light in the wavelength range between 200 nm and 320 nm at the surfaces. Other disinfection methods and apparatuses are provided which generate pulses of light comprising germicidal light and visible light from a germicidal light source and generate pulses of light from a visible light source that is distinct from the germicidal light source. The projections of visible light from the light sources produce a continuous stream of visible light or a collective stream of visible light pulsed at a frequency greater than 60 Hz.
