  • Patent number: 11158926
    Abstract: The invention provides an antenna structure comprising a plurality of wire segments formed in a loop. Connecting units are provided between the wire segments, each of which is switchable between a conductive state and a reactive state. With the connecting units in the conductive state a loop antenna is formed with a first (longer) signal range and with the connecting units in the reactive state an antenna structure is formed with a second (shorter) signal range. Said reactive state is adapted to introduce a phase delay between the adjacent wire segments. This enables the same antenna to be used for long range signal communication and short range communication, for example for system configuration or commissioning. The antenna structure may be used with luminaires of a lighting system.

  • Patent number: 11158540
    Abstract: Light-absorbing masks and methods of dicing semiconductor wafers are described. In an example, a method of dicing a semiconductor wafer including a plurality of integrated circuits involves forming a mask above the semiconductor wafer. The mask includes a water-soluble matrix based on a solid component and water, and a light-absorber species throughout the water-soluble matrix. The mask and a portion of the semiconductor wafer are patterned with a laser scribing process to provide a patterned mask with gaps and corresponding trenches in the semiconductor wafer in regions between the integrated circuits. The semiconductor wafer is plasma etched through the gaps in the patterned mask to extend the trenches and to singulate the integrated circuits. The patterned mask protects the integrated circuits during the plasma etching.

  • Patent number: 11159598
    Abstract: The present invention relates to systems and methods for network labeling in order to enhance real time data transfers. A network for a real time data transfer is identified and predictive models for network performance are compared against to determine if the network is suitable for the data transfer. If the network is predicted to be unsuitable for transmission an alternate means for connection may be suggested. The alternate suggestion may include delaying the data transfer until the network is expected to be in better conditions, connecting to another access point in the network, or switching to another network entirely. During the data transfer, the quality of the network is monitored in order to update the predictive models for the network's quality.
