A floor module for a power generation system may comprise: a housing including a flexible top plate; a plurality of generator assemblies disposed within the housing, each generator in the plurality of generator assemblies comprising: a moveable portion disposed adjacent to the flexible top plate, the moveable portion including a shaft extending away from the flexible top late; and a piezoelectric transducer aligned with the shaft, the piezoelectric transducer configured to compress in response to the moveable portion translating toward the piezoelectric transducer from a force on the flexible top plate.

A system for illuminating at least a portion of an object within an enclosed space includes an object configured to be moved within the enclosed space, and a beacon coupled to the object. The beacon is configured to emit a light tracking signal. A light sensor is configured to detect the light tracking signal emitted from the beacon. A lighting control unit in communication with the light sensor is configured to determine a position of the object within the enclosed space based on the light tracking signal as detected by the light sensor. A lighting assembly is in communication with the lighting control unit. The lighting control unit is configured to operate the lighting assembly to emit the illuminating light onto the at least a portion of the object based on the light tracking signal as detected by the light sensor. The system may also be configured to guide a passenger to a seat, and provide way-finding illumination.

A super first-class cabin includes a monitor disposed in the ceiling structure, a controller to render images on the monitor, and cameras to capture real-time streaming environmental images and renders them on the monitor. At the passenger's request, or when the passenger reclines, the controller may render a selection of mood affective images, for example to promote sleep if desired. Such mood affective images may be organized into a schedule associated with phases of flight to gently wake the passenger and prepare them for the end of the flight. The monitor may be employed to reduce the effects of flight-base time-disassociation by varying a daylight color scheme over the course of long flights, simulating a day/night routine to align the time of day at the origin of the flight with the time of day at the destination.

An in-flight risk management system includes an eye sensor, a seat sensor, and one or more in-flight risk management computers that perform operations including: obtaining history information for a flight crew member, obtaining flight information associated with a flight on which the flight crew member will be present, determining, based on the history information and the flight information, a predicted fatigue profile for the flight crew member, determining, based on the predicted fatigue profile for the crew member, one or more fatigue indicator profiles for the flight crew member, obtaining, from at least one of the eye sensor or seat sensor, one or more measured fatigue indicator values associated with the flight crew member, generating, based on the one or more measured fatigue indicator values, one or more updated fatigue indicator profiles, and generating, based on the one or more updated fatigue indicator profiles, an updated predicted fatigue profile.

An overhead bin in an aircraft includes a liner disposed on an underside of a cabin ceiling and a receptacle that protrudes through an opening in the liner. A bin has a top side with at least one attachment point that includes: a stud mechanically coupled to the top side and a screw disposed within the stud. The stud includes a rounded flange configured to insert into the receptacle for removably securing the bin beneath the liner. An installation method for an overhead bin in an aircraft includes raising the overhead bin to engage the stud with the receptacle, sliding the overhead bin outboard for inserting the stud into the receptacle, and turning a screw within the stud for tightening the stud within the receptacle for securing the overhead bin beneath the ceiling.

An aircraft workstation is disclosed that includes a table that is movable between a stowed position and a deployed position. In one implementation the workstation is incorporated by an aircraft within an exit row. Access to the workstation may be controlled by a latch that locks the table it is stowed position. The workstation may also include a power switch, one or more power sockets, and wire management. The table may incorporate one or more accessories, such as a cupholder, a mouse extender, a table extender, and a stand.

A method and apparatus include attaching a lighted cup holder to a seating arrangement. The lighted cup holder includes a cup holder body and a light-producing light source, with the cup holder body being attached to the seating arrangement and having a cup receptacle therein, the light-producing source being disposed within the cup receptacle for illuminating the receptacle. A light-sensitive element operatively connected to the light source selectively controls production of light by the light source in such a manner that illumination of the cup holder is provided only under conditions where visibility is reduced to the point that it becomes difficult to locate the cup holder. The light-sensitive element is mounted on a master lighted cup holder and controls illumination of the master lighted cup holder and one or more slave lighted cup holders operatively connected to the master lighted cup holder.

A balloon system including a balloon, a payload, and a safety module. A safety module, preferably including a tether and a parachute, and optionally including a cover and/or a drogue. A method of balloon system operation, preferably including operating the balloon system in flight and descending under a parachute.
