  • Patent number: 10486068
    Abstract: A system and method for providing dynamically variable maps in a video game is disclosed. A map is provided that defines a playable space available to one or more game players in a video game. Gameplay is monitored in real-time for the detection of a trigger event. Upon detection of a trigger event, a map management engine dynamically modifies a configuration of the map to improve the gameplay experience based on the type of trigger event. Dynamic modification of a map may comprise altering one or more of the map boundary, and/or the location, position, size, number, state, etc. of one or more static map objects or dynamic map objects. As a result of the dynamic modification of the map, the map may transform from its initial (or first or beginning) configuration to a modified (or new or second) configuration.

  • Publication number: 20190334048
    Abstract: Increasing the power conversion efficiency of silicon (Si) photovoltaics is a key enabler for continued reductions in the cost of solar electricity. Disclosed herein is a multi-junction photovoltaic cell that does not utilize a conventional interconnection layer and instead places a wide bandgap oxide conductor, for example, a metal oxide such as TiO2, between a top light absorption layer having a relatively large bandgap and a bottom light absorption layer having a relatively small bandgap. The advantageous omission of a conventional interconnection layer between the two subcells is enabled by low contact resistivity between the top and bottom light absorbing layers provided by the wide bandgap oxide conductor. The absence of the conventional interconnect between the subcells significantly reduces both optical losses and processing steps. The disclosed photovoltaic cell may thus enable low-cost, high-efficiency multi-junction devices through less complex manufacturing processes and lower material costs.

  • Patent number: 10409984
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing a plurality of stored fingerprints, wherein each of the stored fingerprints is associated with a respective software environment and a respective mobile device; receiving from a first mobile device a first fingerprint of a first software environment in the first mobile device; determining whether the stored fingerprints include less than a threshold amount of fingerprints identical to the first fingerprint; based on a determination that the stored fingerprints include less than the threshold amount of fingerprints identical to the first fingerprint, determining that the first software environment is a compromised software environment; and performing a corrective measure.

  • Patent number: 10376792
    Abstract: A system and method is provided that recommends group compositions in multiplayer video games. The system may suggest a composition of a group of players using a matchmaking process. For example, one or more players may wish to form or join a group of players for a given game, but not know what would be an appropriate mix of player styles, player roles, skill levels, and/or other player characteristics that would make an optimal group, given the player's own characteristics. The system may identify optimal groups based on matchmaking related information such as, without limitation, game profile, player profile, prior match scores, prior quality scores, and/or other information. Optimal groups may be those that have performed successfully (e.g., accomplished the most wins, objectives, etc.), are associated with the highest player enjoyment (e.g., based on match and/or quality scores), and/or otherwise are deemed to be desirable.

  • Patent number: 10344387
    Abstract: The solar fuels generator includes an ionically conductive separator between a gaseous first phase and a second phase. A photoanode uses one or more components of the first phase to generate cations during operation of the solar fuels generator. A cation conduit is positioned provides a pathway along which the cations travel from the photoanode to the separator. The separator conducts the cations. A second solid cation conduit conducts the cations from the separator to a photocathode.

  • Patent number: 10322351
    Abstract: A matchmaking system and method is provided that facilitates optimization of player matches for multiplayer video games. The system may provide a generalized framework for matchmaking using historical player data and analytics. The framework may facilitate automatic determinations of an optimal mix of players and styles to produce the most satisfying user experiences. The system may dynamically update analytical processes based on statistical or otherwise observed data related to gameplay at any given time. In this manner, the system may continually tune the matchmaking process based on observations of player behavior, gameplay quality, and/or other information.

  • Patent number: 10315113
    Abstract: A system and method is provided that simulates gameplay of non-player characters (NPCs) distributed across networked end user devices. The system may identify end user devices that are connected to the system through a network and are available to participate in a simulation in which each participating end user device is provided with one or more NPCs to be executed. An end user device may be available to participate when it has sufficient computing capacity, such as when in an idle or standby state. As such, the system may leverage spare computing capacity of networked end user devices to execute NPCs at networked end user devices during a simulation. In this manner, the behavior of an NPC may be tested using real-world conditions that may affect gameplay, such as a network connection quality, user-to-user game engine coordination and data exchanges, and/or other real-world conditions associated with networked end user devices.

  • Patent number: 10286314
    Abstract: A system and method is provided for continuous gameplay in a multiplayer video game through an unbounded gameplay session. Players may join, exit, and later rejoin a given unbounded gameplay session at any time. A given unbounded gameplay session may therefore continue indefinitely so long as at least one player wishes to continue to gameplay. To facilitate an unbounded gameplay session, the system may score players using time-based or other parameters in a manner that is fair to players who have been playing in the unbounded gameplay session longer than other players.

  • Patent number: 10286326
    Abstract: A soft reservation system and method is provided facilitates an unrequested reservation of a gameplay session in multiplayer video games. A soft reservation may include a match between two or more players for one or more subsequent gameplay sessions that are reserved for the players. The system may, for instance, anticipate an interest by players in a gameplay session and make a soft reservation for the players, who may not have explicitly requested the reservation, to play in the gameplay session. A soft reservation may be made for a player based on a match score, a game profile, a player profile, and/or other information.

  • Patent number: 9976220
    Abstract: A photoanode includes a passivation layer on a light absorber. The passivation layer is more resistant to corrosion than the light absorber. The photoanode includes a surface modifying layer that is location on the passivation layer such that the passivation layer is between the light absorber and the surface modifying layer. The surface modifying layer reduces a resistance of the passivation layer to conduction of holes out of the passivation layer.
