In one embodiment of the present invention, the efficiency of an encoder can be maintained while reducing the complexity of a decoder. Instead of using the database, the query is sent to a query analysis tool that uses a list of columns of interest to resolve ambiguity in the query and then determine if the query potentially accesses the list of columns of interest. The connector assembly includes a cam lever assembly for allowing the user to apply a clamping force to the surgical saw blade with minimum actuation force. The deflecting surfaces are diagonally downwardly directed deflecting ramps by which the wheels are directed toward the safety passenger compartment and below the floor of the motor vehicle as the crumple zone collapses. For example, the high-yield fibers can be contained in the middle layer of a stratified fiber furnish.
