Abstract: Gateway devices, systems, and methods for facilitating control system upgrades including hosting a web application via a gateway device that permits configuration of the gateway device via a web browser. A redundant gateway system can be implemented such that both a primary gateway device and a secondary gateway device are used in conjunction. The web application can provide significant advantages in terms of ease of configurability and integration of legacy input/output (I/O) systems to facilitate control system upgrades in a variety of applications.

Abstract: A method and apparatus for overcoming the cost and time penalties associated with replacing recessed lighting fixtures with flush mount lighting fixtures by using a flush mount trim, which in effect, is a flush mount lighting fixture from which the electrical wiring, lamp, socket and mounting hardware has been removed. The flush mount trim, using a pair of expansion springs, is coupled to the recessed lighting fixture. One or more socket extenders are added to the existing socket in the recessed lighting fixture depending upon the length of the bulb to be used in connection with the flush mount trim.
