Abstract: To address post-booking and other issues, an application may be run on a user device, such as a mobile device, to provide improved, real-time travel organization and messaging. Some embodiments may also be configured to create, maintain, update, and delete a trip container to which trip content can be automatically or manually associated. In some instances, a user may be required to pay a fee to download the application and/or be required to pay a periodic subscription fee to facilitate ongoing functionality of the application. In addition to or instead of downloading the application, hardware (e.g., circuitry), firmware and/or other particular machine components can be configured to implement some or all aspects of the application.

Abstract: A system for sealing a building air duct in response to a chemical or biological attack to prevent the building HVAC system from delivering the chemical or biological agent throughout the building. The system can include an inflatable bladder for disposition within an air duct, a source of gas for expanding the bladder, an initiator for initiating the gas expansion, and a detector for detecting the agent. One bladder is formed of a resilient material suitable for extending into duct corners. Another bladder is larger than the duct to be sealed and is formed of a non-resilient material capable of inflating and bunching into duct corners. One source of gas is a gas canister while another source of gas is a chemical composition capable of reacting and forming the gas. One bladder includes a foaming agent which can expand and solidify within the bladder. One initiator utilizes an electronic signal to initiate the gas expansion. Another initiator includes use of an RF signal to initiate the gas expansion.
