Abstract

Claims (21)

1. An aircraft sanitization system comprising:

an armrest comprising:

a pocket and a top lid,

wherein the pocket is configured to store a tray, and wherein the pocket further comprises:

at least one flat and fixed tongue located between inner walls of the pocket; and

a second set of UV LEDs attached to each face of the at least one tongue and configured to sanitize the at least one of the plurality of portions of the tray;

and wherein the top lid is configured to cover the pocket;

a retractable mechanism enclosed in the pocket, wherein a first end of the retractable mechanism is removably attached to the tray and a second end of retractable mechanism is fixed within the pocket, and wherein the retractable mechanism is configured to:

extract the tray from the pocket in an open state, wherein, in the open state the tray is at least partially outside the pocket; and

retract the tray into the pocket in a closed state, wherein, in the closed state the tray is completely inside the pocket;

a first set of Ultraviolet (UV) Light Emitting Diodes (LEDs) affixed on each inner wall of the pocket, wherein the first set of UV LEDs is configured to sanitize each surface of tray, when the tray is in the closed state;

at least one sensor configured to generate a deactivation signal in response to a predefined criterion; and

a controller communicatively coupled to the at least one sensor, wherein the controller is further configured to deactivate the first set of UV LEDs in response to the deactivation signal generated by the at least one sensor.

2. The aircraft sanitization system of claim 1 , wherein a first end of the top lid is hinged to the armrest to enable rotation of the top lid about a pivot axis and a second end of the top lid cooperates with the armrest to enable the closed state and the open state.

3. The aircraft sanitization system of claim 2 , further comprises:

at least one switch located on the armrest, wherein each of the at least one switch is configured to be:

enclosed and activated by the top lid in the closed state; and

disclosed and deactivated by the top lid in the open state;

a locking mechanism, wherein the locking mechanism is configured to cooperate with the second end of the top lid to enable the closed state and the open state, wherein the locking mechanism engages with the top lid in the closed state and disengages with the top lid in the open state; and

a controller communicatively coupled to each of the at least one switch and the locking mechanism, wherein the controller is configured to activate the first set of UV LEDs, when each of the at least one switch is activated and the locking mechanism engages the top lid in the closed state.

4. The aircraft sanitization system of claim 1 , wherein the tray comprises a plurality of portions hinged to each other, wherein at least one of the plurality of portions is foldable around an associated pivot axis over the remaining plurality of portions.
