Abstract: A method and system for information retrieval are provided whereby at least one search criterion is received from a user; a query is created based on the at least one search criterion; the query is executed to generate results, each of the results corresponding to a respective data entity which satisfies the at least one search criterion; the results are arranged into an order, the order being determined at least in part by a characteristic of the data entity corresponding to each result and a previous act by a user with respect to the data entity corresponding to each result; and the results are displayed to the user.

Abstract: A foldable wheelchair includes a frame having a seat bottom and a seat back movable relative to the seat bottom, wherein the seat back can be moved between a folded position such that the seat back extends generally parallel to a plane defined by the seat bottom and one or more unfolded positions to provide back support to a user. The foldable wheelchair can have a leg support movable relative to the seat bottom and can be moved between an unfolded position to support a user's legs and a folded position such that the leg support extends generally parallel to said plane defined by the seat bottom. In the folded position, the seat back, seat bottom and leg support define generally parallel planes.
