Abstract: The present invention relates to a system for content archiving and management with code readers. The system comprises a combination code comprising a number of code elements, said combination code having a plurality of combinations and capable of interacting with trigger conditions; a code reader for detecting said combination code and trigger conditions upon activation; a content database communicably linked to said code reader, wherein said content database is divided into a plurality of partitions based on different combinations of said combination code and an identity and a privilege order of a user; an output device communicably linked to said code reader and said content database; wherein said output device retrieves and outputs content stored in a corresponding partition of said content database upon said code reader detecting a combination of said combination code.

Abstract: The present application is directed to a horizontally-laid tangential rooftop wind power generator comprising: a generator mounted on a chassis and coupled to a tangential fan wheel or a plurality of tangential fan wheels, all housed in a cover with two long fan openings one at each of the two sides. Wind-directing panels extend outwardly from the two fan openings to form two shrouded duct openings.
