  • Patent number: 10484256
    Abstract: A method for determining that a defect applies to a network device that includes receiving, at a monitoring module, network device information from the network device. The network device information includes state information for the network device and does not include hardware and software version information. The method includes storing, in a network device database, the network device information from the network device and receiving, at the monitoring module, defect information about a defect. The defect information includes network device criteria specifying what state information is required for a network device to be affected by the defect. The method includes storing the defect information in a defect database, determining that the defect applies to the network device based on analyzing the network device information and the defect information from their respective databases, and, based on the determination, informing a defect alert recipient that the defect applies to the network device.

  • Publication number: 20190160101
    Abstract: Non-coding RNA, such as miRNA, expression data derived from a cell population is used to infer the propensity of that cell population for a cellular functional effect for a pre-determined purpose, which effect is temporally, procedurally or interventionally separated from the cell population from which the expression data is derived. Thereby, the cellular functional effect of a cell population can be predicted in order to improve decisions and selections to be made relating to the use of cells, e.g. from cells deriving from different donors or batches, for use in bioprocess application or cell therapeutics, in order to enhance productivity, efficiency and/or efficacy.

  • Publication number: 20190150766
    Abstract: A modular light panel is described that comprises a transparent base substrate, upon a first surface of which is mounted an array of light sources, and a transparent protecting layer arranged to encapsulate the light sources upon the first surface. The refractive index of these layers is such that they form a composite structure for guiding light produced by the light sources within the composite structure. The modular light panel also comprise a wireless communication module and or environment sensor units located on the first surface to measure one or more physical properties of a volume illuminated by the light sources. The modular light panel exhibits increased levels of light output, are easier to manufacture than known devices while offering increased functionality. In addition, they remove the need for separate dedicated environment sensor units to be employed in a room while providing a means for thermally mapping the room.

  • Patent number: 9086516
    Abstract: A light-guide apparatus comprising a light-guide plate for guiding light rays and a plurality of light extraction features is described. The light extraction features comprise a transparent material applied to the light-guide plate so as to form an uneven surface. The transparent material may comprise a textured ink applied to the surface of the light-guide plate via a printing process. The incorporation of an uneven surface provides micro-lens like elements on the surface of the extraction feature which have a higher aspect ratio and so lend themselves to the refraction of the light out of the light-guide plate. In this way a device is produced wherein the size, height, location and surface profile of the extraction features can be carefully controlled. As a result the described light-guide apparatus provides for a highly efficient and relatively uniform light output.

  • Patent number: 9077345
    Abstract: A capacitive sensing apparatus is described that incorporates a light guide having a light scattering means for illumination of the apparatus. The apparatus has a capacitive sensor mounted on a substrate that provides a capacitive sensing area for generating an electric field that emanates from the apparatus. A light source is arranged in optical communication with the light scattering means via the light guide. This arrangement acts to mitigate the effects of interference between the capacitive sensor and the light source. When an opaque substrate is employed an air gap is located between the substrate and the light guide so as to provide a substantially uniform illumination across the light guide. Appropriate selection of the refractive indices of the light guide, ng, and a transparent substrate, ns, provides the same desired uniform illumination in alternative embodiments. The capacitive sensing apparatus finds particular application within a touch sensitive display.

  • Patent number: 9010983
    Abstract: A light guide device for illumination, lighting and display purposes that exhibits an output light having a predetermined, and preferably uniform, angular luminance profile is described. The device comprises a light guide (13) suitable for guiding light coupled thereto and a plurality of extraction features (10, 11) located on one or more surfaces of the light guide. The plurality of extraction features comprises an interleaved pattern of first (11) and second extraction features the arrangement of which provides a means for defining the predetermined angular and spatial luminance profiles for the output light. The device allows for a uniform angular luminance profile to be produced that is maintained even when the light guide is curved or bent.

  • Publication number: 20150043243
    Abstract: A lighting panel that provide an alternative means for producing a “spot light” like illumination from an LED is described. The lighting panel comprising a transparent substrate upon a first surface of which are mounted a plurality of transparent prism structures and upon a second surface of which is mounted a light emitting diode (LED). A transparent guide layer is arranged so as to encapsulate the light emitting diode upon the second surface such that the transparent base substrate and the transparent guide light form a composite structure for guiding light emitted from the LED. The transparent prism structures are configured to extract a first and a second light output from the lighting panel, the first and second light outputs having output angles and beam widths determined by the structure of the plurality of transparent prism structures. The lighting panels exhibit high optical efficiencies and long operating lifetimes.
