Abstract: A system includes a seat pan assembly. The seat pan assembly may include a fixed link having a fore end and an aft end. The seat pan assembly may further include an aft driver link having an aft driver link fore end and an aft driver link aft end, wherein the aft driver link fore end is pivotably coupled to the aft end of the fixed link. The seat pan assembly may further include a fore driven link having a fore driven link fore end and a fore driven link aft end, wherein the fore driven link aft end is pivotably coupled to the fore end of the fixed link.

Abstract: A polyarylborane comprising a substituted polyhedral borane comprising at least 3 exohedrally bonded aryl groups, wherein the substituted polyhedral borane is homo- or hetero-, and each exohedrally bonded aryl group is independently homo- or hetero-, substituted or unsubstituted, and monocyclic or polycyclic. Also, molecules and materials comprising the polyarylborane, and methods for making the polyarylboranes.

Abstract: An access control device controller and method of operation are provided which provide in a first aspect of the invention, a novel way in which to set controller network addresses providing a visually perceivable digital readout to assist installers in setting the correct address, in a second aspect of the invention, automatic configuration of end of line termination resistors, line biasing resistors and earth ground connection to the network medium shield, in a third aspect of the invention, automatic configuration of a controller/host computer data communications link, in a fourth aspect of the invention, a novel method and apparatus for monitoring ambient RF noise levels, and in a fifth aspect of the invention, a novel method of detecting environmental conditions likely to lead to a system failure.
