  • the total treatment duration should conform to other ground turn-around time constraints for the aircraft.
  • the device can be composed for instance, of three or more modules:
  • Cart - being the chassis, wheels, motors.
  • Base - which removably attaches to the Cart and is a covered frame. Attached are lamps with reflective housings and a telescoping mechanism. Electronics components fit within the Base (e.g. controllers/processors, ballasts). Battery pack(s) mount to the front and rear of the Base.
  • Wing Assembly which fits into the Base with a telescoping mechanism that allows vertical translation as described below.
  • the three modules fit together and electrical connections are done via plug type connectors or wirelessly for signal transfer.
  • the Figures demonstrate the feature of the Wing Assembly that telescopes vertically into and out of the Base. This may be accomplished by a variety of known means including a track linear actuator, or a variety of gears, pulleys, chains, belts, etc.
  • FIG. 22 there is a detailed view showing a Trolley with arms transversely extended and vertical support arms which are extended vertically from the trolley and having horizontally extended fixed UVC elements which project UVC light from a higher level above the trolley body trolley outwardly and transversely towards the area above the height of the trolley body.
  • the extended arms can be seen in the undulating type relationship, wherein the support perimeters around the lights are a hinged support with the lights extending between the perimeter supports.

  • the device may feature "modes of operation", controlled via pre-programmed microprocessors, as indicated in the following table:
  • UVC sources may be fluorescent lamps, Light Emitting Diodes (LED), pulsed Xenon and other technologies known to produce ultraviolet light in the germicidal range.

  • Xenon pulsed Xenon
  • the trolley has an estimated weight of approximately 75 pounds.
  • a motor assist for pushing the trolley may be incorporated to ease in its mobility on and off the aircraft.

  • the arms extend substantially laterally and substantially perpendicular to the aisle at variable distance from the trolley.
  • the two arms extend laterally independently to accommodate asymmetric seating configurations.
  • the arms function independently of each other to optimally treat aircraft that may have different numbers of seats on each side of the aisle.
  • UVC light is potentially damaging to human skin and eyes
  • Sensors that monitor motion and heat or visual pattern recognition can be incorporated to detect human presence within a potentially dangerous radius of the device. Audible and visible alarms alert the human to the potential danger.

  • cameras can be included to remotely monitor the trolley's progress. UVC does not penetrate clothing, plastics or glass and very simple personal protective gear covering all skin and a simple visor would allow a worker to be safely adjacent to the trolley.
  • Programming may involve varying levels of automation. For example, one may program for the cabin of a 777 aircraft and the controller determines the direction, speed, number of rows, the desired extension of the arms and height of the UVC sources for the overhead bins. Less sophisticated programming may have variable row numbers, seats per row, speed of trolley travel, depending upon level of contamination etc.

  • the extensible arms have the ability to disinfect surfaces that are not travelled over, but are remote from the travelled surface. Those surfaces, like seats, seat backs and tray tables cannot be travelled over and could not be sanitized are sanitized by the disclosed device which has those extensible arms.
  • An alternative embodiment could have the arms going up and down between seatbacks as the device travels in the aisle to get the arms closer to the sitting surface.
  • An alternative embodiment could have the arms going up and down between seatbacks as the device travels in the aisle to get the arms closer to the seat surfaces.
  • An alternative embodiment is a permanent installation onboard an aircraft with a storage compartment.
  • the device would be stowed in a closed compartment and rather than wheels, for example a ceiling mounted rail system allows the device to travel fore and aft in the passenger compartment.
  • An advantage to this system is that the aircraft can be sanitized regardless of whether the airport has functioning devices.
  • a further advantage is apparent in case of an on-board inflight release of a pathogen, whether accidental/unintentional or bioterrorism. By activating an onboard device, with passengers shielded, an aircraft can be "sanitized" inflight prior to landing. This would avoid release of potential pathogens at the destination and neutralize the threat prior to human inoculation.

Abstract

La présente invention concerne l'assainissement de surfaces dans un emplacement lié à un aéronef. Plusieurs rangées de sièges sont présentes. Un dispositif d'assainissement comprend un corps mobile conçu pour se déplacer le long de l'allée de l'aéronef. Un bras s'étend à partir du dispositif d'assainissement latéralement depuis le corps mobile à travers les sièges, et une source de rayonnement UV montée sur le dispositif d'assainissement est dirigée à travers les sièges, exposant les surfaces de la zone passager au rayonnement UV. Il peut y avoir une unité commandée manuellement, poussée vers le bas de l'allée à la main, les ailes déployées et rangées à la main. Il peut y avoir un bouchon dans une version avec de longs cordons d'extension qu'un humain peut empêcher de s'emmêler. L'opérateur peut être protégé par un équipement de protection cutané et oculaire et il peut exister une commande à distance par un opérateur se tenant debout à proximité.
