  • Patent number: 11847890
    Abstract: An electronic gaming machine includes a display device, a memory device, and a processor. The processor displays a matrix of symbol positions formed by a plurality of reels. The processor also displays a bingo card. The processor determines an outcome that includes a first plurality of symbols to display in the matrix of symbol positions and evaluates the outcome to determine a win amount. The processor populates the matrix of bingo positions with the first prize symbol to a bingo position of the matrix of bingo positions corresponding to a position of the prize symbol in the matrix of symbol positions. The processor evaluates the matrix of bingo positions to determine whether a predefined winning pattern is formed and, in response, determines an award value based at least in part on numerical values of prize symbols forming the predefined winning pattern in the matrix of bingo positions.

  • Patent number: 11849382
    Abstract: Multiple communication paths are established for communications between a User Equipment (UE) and a wireless communication network, before switching between those paths is initiated. Signaling that includes an explicit indication that the UE is to switch between the multiple communication paths is transmitted to and received by at least the UE for which the multiple communication paths were established. Responsive to the explicit indication, communications are switched between the communication paths. At least one of the communication paths includes a relay path between the UE and the wireless communication network through another UE. Establishment of the multiple paths in advance of the switching may be useful in enabling fast switching with low latency and/or no traffic loss.

  • Publication number: 20230377767
    Abstract: Disclosed is a transparent conductive oxide thin film. The metal oxide is a transparent conductive material of (In2O3)x(MO)y(ReO)z formed by doping a small amount of a rare earth oxide ReO into an indium-containing metal oxide MO—In2O3 as a photon-generated carrier conversion center. According to the present application, in an indium-based metal oxide, a rare earth oxide material is introduced, such that the carrier concentration is controlled, and the mobility is improved; rare earth ions in the rare earth oxide have the lower electronegativity, and an ionic bond Ln-O formed by the rare earth ions and oxygen ions has the higher bond breaking energy, such that the oxygen vacancy concentration in the In2O3 thin film may be effectively controlled. The rare earth ions have the ionic radius equivalent to that of indium ions, defect scattering caused by structure mismatch may be reduced, the high mobility characteristics thereof may be kept better.
