Abstract: In a system for making walls, at least two pairs of connector plates are provided, each including receptacle for receiving an end of a structural member. At least one spacer plate is located between and rotatably coupled to successively positioned connector plates. To form a wall, a pair of connector plates is coupled via the retaining means, one to each of a pair of generally opposing ends defined by structural members. The connector plates are rotatably movable relative to the spacer plates thereby allowing the structural members to be oriented relative to one another so as to form a surface having desired contours.

Abstract: In an apparatus for making foundation walls having angled or arcuate contours first and second connecting members are provided. Each connecting member defines at least one joining portion, the connecting members being attachable to a foundation form. When foundation forms are positioned adjacent to one another the joining portions defined by each of the connecting members interlock with one another. An elongating coupling member defining an exterior shape complementary to a shape defined by passages extending through the joining portions is positioned in these passages to rotatably and releasably join the first and second connecting members and thereby the foundation forms together.

Abstract: The present invention is directed toward a system and method for administering incentive offers. A system for administering incentive offers includes a centralized repository for storing offer information, a maintenance engine for updating and maintaining the offer information in the repository, and a retrieval engine for finding and retrieving offers. The system cooperates with an offer presentation engine for configuring and presenting offers based on offeree traits and the environment in which the offer is to be presented. An exemplary system formulates tests to determine effects of changes in content or context, tracks events related to presentation and acceptance of offers, evaluates impact of offer changes on offer effectiveness, and predicts optimum offer content and context based on results of such tests.
