Patent number: 9120018Abstract: Systems and methods are provided to implement a technique for generating interactive events in a simulation, such as creating encounters in an online computer game. In one implementation, encounters are created based on the players and the environment and allow for interaction that is different for different players. Players can select encounters for interaction and choose how to handle the encounter. Encounters may have one or more objectives for participating players to resolve. The objectives for the same encounter may be different for different characters depending on the characteristics of the player characters. If multiple player characters interact with the same encounter, they may each be presented with different objectives, some or all of which may be competing. In addition, the objectives for an encounter may change depending on how other objectives are resolved.Type: GrantFiled: July 22, 2009Date of Patent: September 1, 2015Assignee: Daybreak Game Company LLCInventors: Shawn Lord, Andre Arsenault

Patent number: 8848280Abstract: A photonic crystal device including a photonic crystal material and an activation surface. The photonic crystal material exhibits a first reflectance spectrum in an unactivated state, and, in response to mechanical stimulation, exhibits a second reflectance spectrum in an activated state. Application of a force at an activation portion of the activation surface offset from a material-supporting portion of the activation surface causes a deformation of the photonic crystal material sufficient to bring the photonic crystal material to the activated state.Type: GrantFiled: December 14, 2011Date of Patent: September 30, 2014Assignee: Opalux IncorporatedInventor: Andre Arsenault
