  • Patent number: 11692064
    Abstract: A conjugated azopolymer and methods for making same. The azopolymer includes a plurality of monomer units containing isoindigo with R1 and R2 substituent groups, wherein R1 can be one or more C1 to 30 hydrocarbons; and R2 can be H or F. The azopolymer can have a number average molecular weight (Mn) of 4 to 20 kDa; a weight average molecular weight (Mw) of 12 to 50 kDa; and a poly dispersity index (PDI) of 2 to 3. The polymer can further have selected maximal wavelengths (?max) of 481 to 709 nm and electrochemical reduction events of ?0.4 to ?1.0 V against an Ag/AgCl reference electrode.
    Type: Grant

  • Patent number: 7925601
    Abstract: Techniques enable the reduction of bandwidth requirements for peer-to-peer gaming architectures. In some embodiments, these techniques allow differentiation among players to decide which players should receive continuous updates and which should receive periodic updates. For those gaming systems receiving periodic updates, guided artificial intelligence is employed to simulate activity of a game object based on guidance provided by the periodic updates. Conversely, for those gaming systems receiving continuous updates, the continuous updates may be employed to update the activity of the game object rather than simulating the activity.
