Abstract: A method and system for license authentication over a network. An on-line vendor receives a digital certificate that includes a public key associated with a consumer, and a digital signature of the consumer. A license packet is generated that includes a unique serial number. A record that includes the digital certificate is stored in a memory. The license packet is optionally encrypted with the public key associated with the consumer, and the license packet is forwarded to the consumer. When a post-sale service is required, the consumer generates a request that includes the digital signature of the consumer, and the request is forwarded to the vendor. The vendor accesses the memory to authenticate that the request was sent by the consumer, and if so, the service request is fulfilled.

Abstract: A method in a system comprises accessing a content stream and parsing the content stream into phrases. One or more tokens are determined, at least partially based on the extracted phrases. One or more profiles are associated with the tokens. One or more semantic records are instantiated from the profiles. The semantic record is compared with other semantic records.

Abstract: A child resistant dispensing closure having a cap and a spout mounted thereon for rotation about a substantially horizontal axis. The upper surface of the spout is provided with a plurality of ribs, each of which has a distinct energy plane. Only one rib, usually, the rearmost, allows sufficient purchase to produce the force vector necessary to initiate rotation of the spout when a manual force is applied thereto. The cap includes a cylindrical skirt with a frusto-conical section extending upwardly therefrom. A protective flange extends upwardly about the perimeter of the upper end of the frusto-conical section to deter unauthorized access to the spout. The upper wall of said cap is canted at an acute angle to a horizontal plane passing through the cylindrical skirt of the cap, so that the spout is further recessed within the protective flange.
