Abstract: A vertical wind turbine with a plurality of vertical blades, which are each fastened to a respective vertical blade axis, such that they are pivotable around a respective blade rotation axis (C7) independently of one another, and are supported rotatable on a common circular path (K) around a vertical rotor rotation axis (C2), and a method for operating the vertical wind turbine, wherein pitch angles (?) of vertical blades of the vertical wind turbine, which are driven around a respective vertical blade axis, are predetermined. The pitch angle (?), at least in a partial load mode of the vertical wind turbine (1), is controlled such that the blades (7) rotate with an essentially constant tip speed ratio (?).

Abstract: Products such as instant lottery tickets, pull-tabs, coupons, and gift cards including multi-purpose indicators that function with multiple different systems to enable activation, validation, purchase, use, and/or redemption by such multiple different systems.

Abstract: Some example embodiments of the present invention address growing demand by lottery customers for expanded gaming options and new gaming concepts.

Abstract: Embodiments of the present invention provide a method and system for authentication. In one embodiment, a first identifier associated with an item to be authenticated may be received. A first decryption key associated with the item may also be received. The first identifier may be decrypted using the first decryption key to generate a second identifier. The contents of an authentication database may be searched to find a match for the second identifier. If a match for the second identifier is found in the authentication database, the item may be confirmed as authentic. In embodiments of the present invention, the item may be a lottery ticket, a document, a receipt, a ticket, a credit card, etc.

Abstract: Embodiments of the present invention provide a platform-independent execution environment for executing embedded instructions. In one example, the instructions may be embedded in an active barcode format. In this embodiment a barcode encoded with an instruction may be read. A machine executable instruction may be generated based on the read barcode using a virtual machine. The machine executable instruction may be executed using the virtual machine.
