Abstract: A firewall sealing assembly is provided for use between a firewall and a penetrating member. The assembly comprises a primary seal, a secondary seal, and a plurality of retaining rings. The primary seal is configured to provide a primary seal between the firewall and the penetrating member. The secondary seal is configured to provide a secondary seal between the firewall and the penetrating member. The secondary seal is positioned spaced apart from the primary seal to define a seal cavity there between.

Abstract: A method and apparatus for communicating information between a remote location and a user. Information from the remote location or the user is received by the inventive apparatus and processed by configurable circuitry to a form that can be received and used by the intended recipient. The reconfigurable circuitry can be changed manually by a human user or remotely through the receipt of appropriate signals. Accordingly, the apparatus can be reconfigured to be able to receive information that is transmitted in different forms from those forms that are receivable before reconfiguration.

Abstract: Information can be communicated to or from an electronic device in accordance with a plurality of protocols to provide a plurality of services for the user. The apparatus can operate with any conventional modulation (analog or digital) and in accordance with at least one of the plurality of protocols. If the user is a person, the services can include providing audio or tone signals. If the user is a device, the services can include providing audio, tone, or data signals. The electronic device is a receiver, a transmitter, or transceiver.
