Abstract: Embodiments provide mechanisms for coupling rotor blade pitch to propulsion system tilt angle in an aircraft, and more specifically in electric aircrafts. A system may include a tiltable propulsion system configured to move between a first tilt angle and a second tilt angle, wherein the tiltable propulsion system includes a plurality of rotor blades each configured to move between a first pitch position and a second pitch position; a tilting mechanism coupled to the tiltable propulsion system and configured to move the tiltable propulsion system between the first tilt angle and the second tilt angle; a pitching mechanism coupled to one or more of the plurality of rotor blades and configured to move one or more of the plurality of rotor blades between the first pitch position and the second pitch position; and an actuator configured to operate both the tilting mechanism and the pitching mechanism simultaneously.

Abstract: Embodiments provide scissoring mechanisms for a vertical lift fan of an electric aircraft (e.g., a vertical take-off-landing eVTOL aircraft) where the blades of the vertical lift fan can be opened at almost zero speed. Exemplary scissoring mechanisms have position locking features that keep the collapsed blades in the low drag orientation once closed (e.g., in the stowed position). As a result, the scissoring mechanisms do not cause large impulses during opening and closing that cause large stresses and noise. In addition, the scissoring mechanisms provide an opportunity to check that the fans are opened properly prior to spinning them to the full operating speed. The scissoring mechanisms may not require an extra actuator, and rely on the propulsion motor.

Abstract: An injectable composition for use in invasive oral procedures, including Dexamethasone and ketorolac tromethamine. The composition may also contain a local anesthetic with or without epinephrine. The composition is delivered using a dental syringe typically used for administering local anesthesia. The needle is inserted below the submucosally and the mixture is delivered via local infiltration adjacent the procedure site at the preoperative or intraoperative stage. The local infiltration of the medication provides improved postoperative pain control, reducing swelling and decreasing the need for postoperative opioid consumption. Ketorolac tromethamine may also be administered after the procedure.
