Abstract: In selected embodiments a recommendation generator builds a network of interrelationships between venues, reviewers and users based on their attributes and reviewer and user reviews of the venues. Each interrelationship or link may be positive or negative and may accumulate with other links (or anti-links) to provide nodal links the strength of which are based on commonality of attributes among the linked nodes and/or common preferences that one node, such as a reviewer, expresses for other nodes, such as venues. The links may be first order (based on a direct relationship between, for instance, a reviewer and a venue) or higher order (based on, for instance, the fact that two venue are both liked by a given reviewer). The recommendation engine in certain embodiments determines recommended venues based on user attributes and venue preferences by aggregating the link matrices and determining the venues which are most strongly coupled to the user.

Abstract: A liquid crystal cell (40) for an electron beam-addressed liquid crystal light valve has a rigid glass substrate (16) and target substrate (44) formed of thin flexible material. The cell (40) is constructed so that the spacing between the flexible substrate (44) and the rigid substrate (16) is precisely maintained. A fixture (72) is employed for attaching the target substrate (44) to the rim (102) of the light valve body (14) prior to assembly of the cell (40).
