The system 300 may further include a database or remote memory 304. The database 304 may be located on a same aircraft as the system 300 or may be located remote from the aircraft. The controller 302 may communicate with the database 304 via any wired or wireless protocol. In that regard, the controller 302 may access data stored in the database 304. The database 304 may store identifiers associated with users of the system 300 and may store specific settings for various components of the ejection system 200 that are associated with each of the user identifiers. For example, a first user identifier may be associated with a first set of settings for the ejection system 200 and a second user identifier may be associated with a second set of settings for the ejection system 200. The controller 302 may access the specific settings for each user identifier by comparing the user identifier to the database 304.
The system 300 may include various components that are removably coupled to other components in the cockpit 104. For example, the system may further include a harness fitting 216 that restrains the user 202 in the seat 204. A harness connector 218 may be coupled between the harness fitting 216 and a connector 220 of the seat 204. The harness connector 218 may be removably coupled to both of the harness fitting 216 and the connector 220 such that the user 202 may carry the harness connector 218 with him between aircraft. In various embodiments, the harness fitting 216 may be removably coupled to the aircraft (and the harness connector 218 permanently or removably coupled to the harness fitting 216) such that the user 202 may carry the harness fitting 216, with the harness connector 218, with him between aircraft.
The helmet 206 may likewise be included in the system 300 and may include a helmet connector 212 that connects the helmet 206 to a connector 214 in the seat 204 or another portion of the cockpit 104. For example, digital or analog data may be transmitted between the helmet 206 and various components of the cockpit 104 via the helmet connector 212 and the connector 214. The helmet connector 212 may be removably coupled to both of the helmet 206 and the connector 214 such that the user 202 may carry the helmet connector 212 with him between aircraft. In various embodiments, the helmet connector 212 may be permanently or removably coupled to the helmet 206 such that the user 202 may carry the helmet 206, with the helmet connector 212, with him between aircraft.
The system 300 may also include a communication system 222 which may include any one or more of a speaker, a microphone, a radio or other device capable of wireless or wired transmissions. In various embodiments, the communication system 222 may be integrated with the helmet 206. A communication connector 224 may be coupled between a component of the communication system 222 (e.g., a headset, a radio, a transmitter, or the like) and a connector 226 coupled to the seat 204 or another portion of the cockpit 200. The communication connector 224 may be removably coupled to both of the component of the communication system 222 and the connector 226 such that the user may carry the communication connector 224 with him between aircraft. In various embodiments, a component of the communication system 222 may be removably coupled to the aircraft (and the communication connector 224 permanently or removably coupled to the component of the communication system 222) such that the user may carry the component of the communication system (with the communication connector 224) with him between aircraft.
The system 300 may further include an oxygen mask 228. The oxygen mask may deploy in response to at least one of a lack of pressure in the cockpit 104 or another trigger in order to provide a flow of oxygen to the user 202. In various embodiments, the oxygen mask 228 may integrated with the helmet 206. An oxygen connector 230 may be coupled between the oxygen mask 228 and a connector 232 of the seat 204 or another portion of the cockpit 104. The oxygen connector 230 may be removably coupled to both of the oxygen mask 228 and the connector 232 such that the user may carry the oxygen connector 230 with him between aircraft. In various embodiments, the oxygen mask 228 may be removably coupled to the aircraft (and the oxygen connector 230 permanently or removably coupled to the oxygen mask 228) such that the user may carry the oxygen mask 228 (with the oxygen connector 230) with him between aircraft.
Each of the helmet connector 212, the harness connector 218, the communication connector 224, and the oxygen connector 230 may communicate with the controller 302 (e.g., either via the respective connectors 214, 220, 226, 232 or via the helmet 206, the harness fitting 216, the communication system 222, or the oxygen mask 228, respectively). At least one of the helmet connector 212, the harness connector 218, the communication connector 224, and the oxygen connector 230 may include a connector portion (e.g., a set of pins, a portable memory integrated in the respective connector, or any other digital or analog feature) which includes information corresponding to the user 202. In that regard, the controller 302 may determine or identify information corresponding to the user 202 by analyzing the connector portion of the respective connector (which is carried by the user 202 between aircraft). Thus, the information corresponding to the user 202 may be automatically learned by a controller of a cockpit of any aircraft with a system similar to the system 300 by analyzing the connector portion of the respective connector. The information corresponding to the user 202 may include physical characteristics of the user 202, information usable to determine an identifier of the user 202, specific settings for components of the ejection system 200, or the like.
The controller 302 may adjust various settings of the ejection system 200 based on the information corresponding to the user 202. The controller 302 may directly control the various settings of the ejection system 200 or may provide instructions to components of the ejection system 200 and those components may adjust the settings. For example, the ejection system 200 may include a seat electronic sequencer 324, a seat electronic position controller 326, an interseat electronic sequencer 338, and the like. Each of the seat electronic sequencer 324, the seat electronic position controller 326, and the interseat electronic sequencer 338 may include one or more logic devices such as one or more of a central processing unit (CPU), an accelerated processing unit (APU), a digital signal processor (DSP), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), or the like. In various embodiments, these elements may further include any non-transitory memory known in the art. The seat electronic sequencer 324, the seat electronic position controller 326, and the interseat electronic sequencer 338 may be coupled to the controller 302 and may receive the specific settings from the controller 302 or may receive instructions regarding adjustments of components of the ejection system 200 from the controller 302.
The seat electronic sequencer 324 may make adjustments to components of the ejection system 200 that alter a sequence or timing of ejection events such as settings associated with the drogue 210, the main parachute 208, and a thrust angle of the seat 204 during ejection. For example, the seat electronic sequencer 324 may set a parachute deployment timing corresponding to a delay between ejection and deployment of the main parachute 208. The seat electronic sequencer 324 may further set a drogue deployment timing corresponding to a delay between ejection and deployment of the drogue 210. The seat electronic sequencer 324 may further adjust the angle 333 of the seat 204 relative to the fuselage 102 of
The seat electronic position controller 326 may make adjustments to components of the ejection system 200 that affect a position of a user within the system 200 such as positions of various elements of the seat 204. For example, the seat electronic position controller 326 may adjust a position of a headrest 328 (e.g., in any two or more directions corresponding to a front of an aircraft, a rear of an aircraft, closer to a floor surface 331, farther from the floor surface 331, towards a starboard side, and towards a port side). The seat electronic position controller 326 may further control a seat height actuator 336 to adjust a seat height 330 of the seat 204 (e.g., to increase or decrease the seat height 330). The seat electronic position controller 326 may further adjust a rail angle 333 corresponding to an angle between seat rails 332 and the floor surface 331. The seat electronic position controller 326 may further adjust a lumbar support 334 to extend closer to or farther from a surface 335 of a backrest 337.
The interseat electronic sequencer 338 may make adjustments to components of the ejection system 200 that affect an interseat timing between components. For example, the interseat electronic sequencer 338 may adjust a timing or delay between ejection of the seat 204 and separation of at least one of a hatch or canopy (e.g., the hatch or canopy 106, 110 of
As alluded to above, the various adjustable settings of the ejection system 200 may vary based on at least one of physical characteristics of a user or user preferences. In that regard, the specific settings of the user stored in the database 304 or stored in the connector portion of the respective connector (i.e., at least one of the helmet connector 212, the harness connector 218, the communication connector 224, and the oxygen connector 230) may include at least one of physical characteristics of the user or specific user preferences. The controller 302 or one or more of the seat electronic sequencer 324, the seat electronic position controller 326, or the interseat electronic sequencer 338 may select values for the various adjustable settings based on the one or more of the physical characteristics of the user or the user preferences. For example, the physical characteristics may include at least one of a weight of the user, a gender of the user, a sitting height of the user (e.g., a length of at least one of a torso or a head of the user), a location of a center of gravity of the user relative to other parts of the body of the user, a reach of the user (e.g., corresponding to at least one of an arm length or a leg length of the user), or the like. In various embodiments, the physical characteristic may include a distance measurement of the user such as a height of the user, the sitting height of the user, the reach of the user, or the like.
In various embodiments, the specific settings of the user stored in the database 304 or stored in the connector portion of the respective connector may include specific values of the adjustable settings instead of, or in addition to, the physical characteristics or the user preferences. In that regard, the controller 302 may adjust the settings of the ejection system 200 based on the specific settings of the user 202.
In various embodiments, the connector portion of the respective connector may include an identifier of the user 202. The controller 302 may retrieve the specific settings of the user 202 from the database 304 using the identifier.

The connector portion 400 (which includes the information related to the user) may include a set of pins 404 of the plurality of pins 402. The set of pins 404 may include at least one pin. In various embodiments, the connector portion 400 may further include a non-transitory memory 405 which stores the information related to the user. In such embodiments, the information from the memory 405 may be transmitted directly or indirectly to the controller 302 via the set of pins 404.
In various embodiments, each of the set of pins 404 may represent a logical one or a logical zero, depending upon whether a given pin is present. For example, the set of pins 404 may include nine pins 406, 408, 410, 412, 414, 416, 418, 420, 422). Each pin (e.g., the pin 406) may represent a logical zero in response to the pin being removed from the connector portion 400 (including being adjusted so it fails to make contact with a respective connector) and may represent a logical one in response to the pin being present (and able to make contact with a respective connector). In that regard, the set of pins 404 may represent information corresponding to the user. For example, a first combination of logical values of the pins 406, 408, 410, 412, 414, 416, 418, 420, 422, respectively, may be 100110010 and a second combination of logical values of the pins 406, 408, 410, 412, 414, 416, 418, 420, 422, respectively, may be 100110011. The first combination of logical values may represent a first user identifier and the second combination of logical values may represent a second user identifier.
As another example, the pins 406, 408, 410, 412, 414, 416, 418, 420, 422 may be grouped such that each grouping represents a different physical characteristic. For example, the pins 406, 408, 410 may represent a weight of the user (e.g., 110 may represent a weight between 150 and 165 pounds), the pins 412, 414, 416 may represent a height of the user (e.g., 101 may represent a height of between 5 feet 10 inches and 6 feet), and the pins 418, 420, 422 may represent a reach of the user (e.g., 011 may represent an arm length of between 3 feet and 3 feet 4 inches).
As yet another example, the pins 406, 408, 410, 412, 414, 416, 418, 420, 422 may represent specific settings of the user. For example, a combination of logical values of the pins 406, 408, 410, 412, 414, 416, 418, 420, 422, respectively, may be 110110111. This combination may represent a specific thrust angle, a specific rail angle, and a specific seat height.
The logical values of the pins 406, 408, 410, 412, 414, 416, 418, 420, 422 may be used in any combination to represent any one or more of identifiers of users, physical characteristics of the users, or specific settings of the users.

In block 504, a controller of the system may determine an identifier of the user based on the connector portion of the connector. For example, the controller may analyze a logical value represented by specific pins of a set of pins to determine the user identifier associated with the user.
In block 506, the controller may retrieve specific settings of the user corresponding to settings of an ejection system from a database using the user identifier. For example, the controller may access the database and compare the user identifier to user identifiers stored in the database, and may retrieve the specific settings associated with the user identifier.
In block 508, the controller may adjust at least one of a plurality of adjustable settings (e.g., those described above with reference to the seat electronic sequencer, the seat electronic position controller, and the interseat electronic sequencer) based on the specific settings retrieved from the database.
Referring now to
In block 604, a controller of the system may determine at least one characteristic of the user (e.g., a weight, a height, a distance, a center of gravity, or the like) based on the connector portion. For example, the controller may analyze a logical value represented by pins of a set of pins to determine the at least one characteristic.
In block 606, the controller may adjust at least one of a plurality of adjustable settings (e.g., those described above with reference to the seat electronic sequencer, the seat electronic position controller, and the interseat electronic sequencer) based on the at least one characteristic of the user. In various embodiments, the controller may determine optimal settings by comparing the user characteristic to a database.
Turning now to
In block 704, a controller may determine at least one specific setting of a user based on a connector portion of the connector. For example, the controller may analyze a logical value represented by pins of a set of pins to determine the specific setting of the user.
In block 706, the controller may adjust at least one of a plurality of adjustable settings (e.g., those described above with reference to the seat electronic sequencer, the seat electronic position controller, and the interseat electronic sequencer) based on the specific settings determined by the controller.
