Abstract: Systems and techniques are provided for linking subjects in an area of real space with user accounts. The user accounts are linked with client applications executable on mobile computing devices. A plurality of cameras are disposed above the area. The cameras in the plurality of cameras produce respective sequences of images in corresponding fields of view in the real space. A processing system is coupled to the plurality of cameras. The processing system includes logic to determine locations of subjects represented in the images. The processing system further includes logic to match the identified subjects with user accounts by identifying locations of the mobile computing devices executing client applications in the area of real space and matching locations of the mobile computing devices with locations of the subjects.

Abstract: Methods and apparatus for playing an instant win gaming ticket. An instant win gaming ticket has multiple instant win games which can be played by the player. The amount won per game is dependent on the results of at least one previous game on the same ticket. The player plays the games on a single ticket and the amount the player wins for each game depends on whether previously played games on the same ticket were won or lost.

Abstract: A photographic flash lamp having a closed, at least partially transparent capsule. A combustible material within an enclosed region of the capsule generates a flash upon ignition. Ignition is provided by a frictionally ignited composition within the enclosed region and an ignitor to frictionally engage with the composition. A frictional ignitor assembly extends between an interior and exterior of the enclosed region and carries one of the composition or ignitor. Movement of an exterior end of the ignitor assembly causes the frictional ignitor and frictionally ignited composition to frictionally engage one another resulting in flash generation. Particularly with a sliding piston arrangement for engaging the ignitor and frictionally ignited composition, ignition can be accomplished with very low cost components such as a spring while at the same time, combustion gases are trapped within the closed envelope.
