A level sensor for detecting a level of content in a tank, the level sensor (400a, 400b) comprising a flexible cable (102) at an end of which is attached a float sensor (104), the float sensor configured to be suspended from the cable in the tank, in use, and to change its orientation as it contacts content in the tank, and wherein the float sensor is activated to generate a level sense indication according to its orientation.

A system for localizing and object is disclosed herein. The system includes a radio transmitter (310) disposed in a first location, a radio receiver (312) disposed in a second location, a processor operatively coupled to the radio transmitter (310) and to the radio receiver (312), and a memory (512) operatively coupled to the processor. The memory (512) includes instructions stored thereon that, when executed by the processor, cause the processor to send a first command to the radio transmitter (310) to transmit a continuous radio wave, send a second command to the radio receiver (312) to receive a reflected radio wave, receive from the radio receiver (312) a signal indicating the reflected radio wave is within a spatial region of interest, and determining a three-dimensional location of the object within the spatial region of interest based on the reflected radio wave.

Disclosed are methods (100; 300) for quantifying the cleanability of a surface (202; 402) of an article (204; 404), for instance an aircraft interior component. In embodiments, a solution containing an artificial "dirt" is introduced to a surface under test to simulate a sullied condition. The sullied surface is subjected to at least one cleaning process. Obtained reference and post-cleaning light measurements are compared to determine a measurement difference corresponding to a cleanability of the surface and/or effectiveness of the at least one cleaning process. In embodiments, the measurement difference is assigned a cleanability score for at least one of determining a passing or failing cleanability, modifying the cleaning process, indicating the need for a second or subsequent cleaning, modifying the barrier coating formulation, redesigning the article, etc. The disclosed methods provide solutions for objective verification measures of surface cleanability used to facilitate new article designs, materials, barrier coatings, cleaning processes, cleaners, etc.

A passenger cabin layout including a closet and a closet positionable in a cabin such as an aircraft passenger cabin. The closet includes a first compartment (116) for accommodating a wheelchair (118), such as an occupied wheelchair, in an unfolded condition, wherein the first compartment is enterable from an aisle in the cabin, such as a branch aisle extending from a door of the aircraft. The closet further includes a second compartment (130) for storing items. In some embodiments, the first compartment is further enterable from a second branch aisle forward of at least one passenger seat, such as a seat row facing the closet. The first compartment is configured to accommodate a personal wheelchair and in some embodiments includes a floor pallet (126) for securing the wheelchair in place in atop the pallet.

The present invention relates to a retainer assembly (10) for retaining a container (52, 54) within a compartment of an aircraft galley. The assembly includes a housing (12) comprising an opening (11), a frame (16) defining a retainer slot (17) located within the housing and arranged to be fixed relative to the housing, a retainer (18) configured to be located in the retainer slot (17), wherein the retainer (18) and retainer slot (17) are arranged to allow linear motion of the retainer within the retainer slot in a first direction away from and towards the opening and restrict movement of the retainer in all other directions; and a rotatable shaft (14) extending through at least a first wall of the housing (12) and the frame (16) in a second direction perpendicular to the first direction. The rotatable shaft (14) and the retainer (18) are arranged so that the rotation of the rotatable shaft causes a linear motion of the retainer within the retainer slot between a stowed position and deployed position. The invention further extends to an aircraft galley (50) compartment incorporating the retainer assembly (10), and a method of retaining a container (52, 54) within an aircraft compartment (50).
