Abstract: A system for determining a health status of a positive temperature coefficient resistor (PTCR) heater assembly includes a PTCR heater assembly and a health monitoring system. An input voltage is provided to the PTCR heater assembly to provide heating. The health monitoring system includes a first sensor configured to sense the input voltage at the PTCR heater assembly and a second sensor configured to sense a current through the PTCR heater assembly. The health monitoring system is configured to determine a baseline characteristic and an observed characteristic each relating to an inrush peak of the PTCR heater assembly and based on the input voltage and the current. The health monitoring system compares the observed characteristic to the baseline characteristic to assess a health status of the PTCR heater assembly and outputs the health status for PTCR heater assembly diagnostics and/or prognostics.

Abstract: An angle of attack sensor includes a housing and a faceplate. A vane assembly extends through a central opening of the faceplate and includes a vane. The vane comprises a root, a tip, a leading edge, a trailing edge, a first lateral face, and a second lateral face. The first lateral face and the second lateral face are symmetric about a chord of the vane and each have a forward section with an outer surface profile that is nonlinear and geometrically convex from the leading edge to a transition point at a tangent to the widest point of the geometrically convex outer surface profile and each have an aft section with an outer surface profile that extends out to form a diverging wedge shape from the transition point to the trailing edge.

Abstract: An angle of attack sensor includes a housing having an open end and a closed end, a faceplate positioned on the open end of the housing, the faceplate comprising a periphery at an outer edge of the faceplate, a central opening, and an exterior surface extending from the periphery to the central opening, and a vane assembly extending through the central opening of the faceplate. The exterior surface of the faceplate has a sloped profile from the periphery to the central opening.

Abstract: Described are assemblies that include elements of a tray table, such as for an aircraft or other passenger craft. A tray table body can be movable between a stowed configuration and a deployed configuration. A set of arms may support the table body relative to a seat back in the stowed configuration and in the deployed configuration. In response to movement of the seat back (such as in a crash scenario), the arms may permit release of a constraint of the tray table body that would otherwise inhibit the tray table body from moving with the seat back.

Abstract: Track fitting assembly having a base frame (12) comprising a pivot shaft (44) arranged so that the pivot shaft substantially aligns with an upper surface of a track when the base frame is coupled to the track and at least one pivotable insert (14) pivotally coupled to the pivot shaft.

Abstract: Described herein are personal electronics device mounting assemblies including a passenger seat and a case assembly comprising a case configured to receive a personal electronic device and a male structure pivotally coupled to the case. The personal electronic device mounting assemblies may also include a mounting assembly comprising a female slot structure and a support bracket structure, the female slot structure may be configured to releasably receive the male structure and the support bracket structure may be configured to attach to the passenger seat. The mounting assembly may be configured to provide support to the case when the male structure is in an extended position and the female slot structure has received the male structure.

Abstract: Described herein are integrated keyboard tray assemblies including a tray table comprising a top surface of substantially planar construction and a body, wherein the top surface may be disposed above the body when the tray table is in an open position. The integrated keyboard tray assemblies also including a passenger seat, wherein a rear portion of the passenger seat may share a pivotal connection with at least the body of the food tray, and a sensor adjacent the tray table and configured to detect a user interaction at the top surface of the tray table when the tray table is in the open position.

Abstract: A safety belt (104) is secured to a seat structure (102) using movable anchor points (114, 116, 406). In an embodiment, a y-belt (104) is attached to left and right pivotable anchor plates (110). The anchor plates (110) pivot when a load is applied to the safety belt (104), thus allowing the anchor points to self-align to maintain an equal amount of tension across the lower and higher portion of the seat belt. In a different embodiment, a 2-point safety belt (708) is attached to slidable anchors (406) that move within channels (404) in response to load applied to the safety belt, allowing the anchor points to self-align to maintain proper tension and positioning of the safety belt (708).

Abstract: The present invention generally relates to passenger aircraft seats. Some examples provide systems for integrating a child seat into a certified aircraft seat. Some examples include a passenger seat backrest having an integrated child seat. An integrated child seat base may be moved between a stowed position and a deployed position. When in the stowed position, the integrated child seat base may fit within a recessed surface of the seat backrest and the seat may then accommodate an adult passenger. When in a deployed position, the integrated child seat may then accommodate a child passenger. The integrated seat may include a harness system that extends through the seat backrest and couples with an internal support structure of seat backrest. In some embodiments the mounting points of the harness system may be reinforced with stiff brackets attached to the internal support structure.
