Abstract: An offer including an offered benefit is provided for transmission to each of a plurality of first users who meet criteria for being part of a group of first users. Each user of the first users is provided the offer and has an opportunity to accept the offer. When accepted, the first user who accepted the offer receives the offered benefit and releases information to the offeror.

Abstract: A fabrication arrangement using plural LSI chips to make a bit stream detection system requiring a programmable logic array which is too large to fit on a single LSI chip. Due to the small number of input/output pins available on any LSI chip, the fabrication arrangement divides among the chips an input shift register, the array, and array input latches. Each LSI chip also has time-multiplexed array outputs and time-multiplexed feedback inputs that minimize the pins and enable interconnection among the array section outputs on the chips so that they combine into the single large array required by the detection system. These LSI chips can be identically fabricated.
