  • Patent number: 12269581
    Abstract: A system of a multi-rotor aircraft that capitalizes on the advantages of fixed wing elements combined with rotary wing structures. The fixed wing elements can help to generate lift once the aircraft is airborne and can thus reduce the need for larger lifting rotors which can allow for longer flight times and distances. Additionally, the systems disclosed herein take advantage of a partial in-wing configuration with a number of rotors to reduce the overall footprint of the vehicle while maintaining the flight efficiency that comes with combining features of fixed and rotary wing elements, and increasing operator safety by shrouding rotating parts. The unique configurations allow for a decoupling of the pitch, yaw and roll authority to reduce the complexity in control systems and improve the flight efficiency of the aircraft. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque.

  • Patent number: 12186151
    Abstract: Examples of apparatus, methods, and compositions for endodontic treatments are described. The apparatus can include a fluid platform configured to substantially retain fluid in a tooth chamber during treatment. The fluid platform can help maintain fluid circulation in the tooth chamber as fluid flows into and out of the tooth chamber. The apparatus can also include a pressure wave generator configured to generate acoustic waves that can be used for cleaning root canals and tooth surfaces in the tooth chamber. Examples of pressure wave generators include a liquid jet, an electromagnetic energy delivery device, and an ultrasonic device. The fluid can include antiseptic or antibacterial solutions to assist in tooth cleaning. The fluid may be degassed to have a reduced dissolved gas content (compared to non-degassed fluids used in endodontic treatments), which may improve the effectiveness of the pressure wave generation or the cleaning.

  • Publication number: 20240286735
    Abstract: A collective pitch adjustment mechanism for a variable-pitch rotor that has blades for rotation about a rotor axis, e.g., for a flight vehicle or drone, via a motor. The mechanism has a servo actuator and a bearing cage for blade rotation. The servo actuator varies the collective pitch of the blades via a pushrod, and a servo actuator arm is configured for rotation and connected to the pushrod via a joint. Mounting portions are provided for securement of the blades and an actuation horn is coupled to the pushrod. The blades are rotationally and/or translationally coupled to the actuation horn via the mounting portions. The servo actuator causes rotational movement of the servo actuator arm, which in turn causes translational movement of the pushrod, which causes linear movement of the actuation horn to thereby collectively cause a collective change in a pitch angle, i.e. the collective pitch, of the blades.

  • Patent number: 11975824
    Abstract: A system and method for controlling a multi-rotor aircraft that implements the unconventional use of an odd number of rotors. The odd or auxiliary rotor is designed to be smaller in diameter than the remaining main rotors and accordingly generates a smaller unbalanced torque and pitch on the aircraft. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque from the odd auxiliary rotor.

  • Patent number: 11918432
    Abstract: Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

  • Patent number: 11731759
    Abstract: A system and method for controlling a multi-rotor aircraft that implements the unconventional use of different sized rotors. The different sized rotors than the main rotors tend to generate an unbalanced torque and pitch on the aircraft that effectively decouples the pitch and yaw control from the main rotors. The atypical design tends to lend itself to improved control capabilities and simplified control systems. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque from the odd auxiliary rotor.
