  • Publication number: 20150310471
    Abstract: A method and system for generating and processing socially gamified offers. It comprised a software application for specifying the offer parameters such as discount, expiration date, gamification type, posting the offers to a network, and monitoring the gamification outcomes to unlock the offer. It further comprises a server and a software application for redistributing the offers and managing the gamified interactions. It further comprises of a gamification engine that allows the offers to be activated based on different types of interactions by the network users. The gamification can require reaching a threshold of social endorsements for the offer to activate. Various types of gamification algorithms are used to create different types of engagements with the network participants.

  • Patent number: 7183497
    Abstract: A multilayer wiring board (11) is provided which includes a core substrate (12) including a plurality of through-holes (15). The through-holes (15) include through-hole conductors (17) on the inner walls of corresponding penetration holes (16) of a diameter of 200 ?m or less. Interlayer insulating layers (31, 32) are disposed on opposite sides of the principal planes (13, 14) of the core substrate (12). Wiring layers (23, 24) are disposed on the surface of interlayer insulating layers (31, 32). The through-holes (15) are filled with a hardened filling material (18). Lid conductors (21, 22) close the openings of the through-holes (15). The value of linear expansion of the hardened filling material (18) is 1.2% or less in the temperature region from room temperature to the solder reflow temperature. The board has excellent connection reliability and exhibits little or no cracking or delamination in the lid conductor closing the openings of the through-holes and in the surrounding conductor area.
