Abstract: The present invention relates to a system and a process for providing improved operational safety for aircraft. The system/process of the instant invention utilizes real-time, two-way transmission of voice and/or text and flight-critical data between an aircraft and a ground-based computer workstation, where transmitted information monitored and acted upon as necessary by a qualified flight safety person, e.g., a appropriately trained individual (including but not limited to a safety pilot or other person trained in safety procedures). This safety person can perform a number of functions that would enhance flight safety, such as reducing the workload of the primary pilot(s), assisting in the performance of routine checklists, monitoring communications with air traffic control, and advising the pilot in the aircraft on how to handle any in-flight situations that may arise.

Abstract: A smoker's booth for isolating, containing, venting, and filtering tobacco smoke. The booth has a walled enclosure with a modular room divider system using hollow walls, filtration, and blower devices to remove tobacco smoke from workplace air.

Abstract: A smoker's booth for isolating, containing, venting, and filtering tobacco smoke. The booth has a walled enclosure with a smoker's access aperture. The presence of a smoker is detected, thereby activating the venting, filtering, and lighting mechanisms. The booth can be wall mounted or freestanding.
