  • Patent number: 11730376
    Abstract: A non-invasive and convenient method and apparatus for approximation of left ventricular end diastolic pressure (LVEDP) can be used in both hospital/clinic environments and nursing home or home environments. The method and apparatus use non-invasive sensors and a new “cardiac triangle” computational method to obtain an approximation of LVEDP. The computational method uses hemodynamic and electrocardiogram (ECG) waveforms as input, which can be collected by a portable device or devices.

  • 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.

  • Publication number: 20230028923
    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.

  • Publication number: 20230022589
    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: 20220370177
    Abstract: Various systems, method, and compositions for treating a tooth are disclosed herein. For example, an apparatus for treating a tooth is disclosed. The apparatus can include a chamber having an access port which places the chamber in fluid communication with a treatment region of the tooth when the chamber is coupled to tooth. A fluid motion generator can be coupled to the chamber. The fluid motion generator can be configured to direct fluid across the access port to generate fluid motion in the chamber. In various embodiments, fluid motion (e.g., vortices, swirl, etc.) can be induced at or near treatment regions of the tooth, such as a root canal or carious region.

  • Publication number: 20220297822
    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.

  • Publication number: 20220296346
    Abstract: Systems and methods for using a liquid jet apparatus for dental treatments are disclosed. In one implementation, the liquid jet apparatus may include a handpiece configured to deliver a high velocity liquid jet to a desired location in the mouth of a patient. The handpiece may include a positioning member having a channel through or along which the jet can propagate. The positioning member may have a distal end portion configured to be at least partially disposed in a pulp cavity, canal space, or opening in the tooth under treatment. During operation, the jet may impact an impingement surface of the distal end portion of the positioning member and be deflected as a spray through one or more openings in the distal end portion. The liquid jet apparatus may be used for root canal treatments.

  • Publication number: 20220212792
    Abstract: A network of high-resolution cameras for monitoring and controlling a drone within a specific operational environment such that the latency time for communication between the cameras and drone is less than that of human controlled drones. The drone can communication drone health data to the network of cameras where such information can be combined with visual image data of the drone to determine the appropriate flight path of the drone within the operational environment. The drone can then subsequently be controlled by the network of cameras by maintaining a constant visual image and flight control data of the drone as it operates within the environment.

  • Publication number: 20220185464
    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: 11229809
    Abstract: Systems and methods for targeting specific cell types by selective application of ultrasonic harmonic excitation at a resonance frequency (“oncotripsy”) for the specific cell types are presented. The systems and the methods result in permeabilization, lysis, and/or death of the targeted specific cell types by using ultrasonic harmonic excitations that have a frequency and a pulse duration specifically tuned to disrupt nuclear membranes of the targeted specific cell types by inducing a destructive vibrational response therein while leaving non-targeted cell types intact. Target cells may be neoplastic.
