Abstract: A rotorcraft swashplate assembly includes a rotationally fixed swashplate fixed against rotating with a rotorcraft rotor. The swashplate assembly also includes a rotatable swashplate coupled to the rotor to rotate with the rotor. The swashplate assembly also includes multiple pitch change links, each pitch change link coupled to a respective rotor blade and to the rotatable swashplate to rotate with the rotor. The swashplate assembly also includes an annular track coupled to the rotationally fixed swashplate and configured to support each pitch change link riding on the annular track as each pitch change link rotates with the rotor. The track includes multiple bearings upon which a pitch change link rides, and actuators that move the bearings changing a shape of the annular track and thereby the pitch of each rotor blade as each pitch change link rides on the annular track during rotation of the rotor blades.

Abstract: Systems, methods, and media for generating and sending indications of interest in trading systems are provided. In some embodiments, systems for generating and sending indications of interest in trading systems are provided, the systems comprising: at least one hardware processor that: determines whether an order is blocked from inclusion in an indication of interest; determines whether the order is marketable; generates the indication of interest so that it includes at least a portion of the order when the order is determined to not be blocked and the order is marketable; determines whether the indication of interest is blocked from being sent to a destination; and sends the indication of interest to the destination when the indication of interest is determined to not be blocked from being sent to the destination.
