  • Patent number: 11686388
    Abstract: A nonlinear closed-loop control combined with an integral time-delay feedback control is disclosed to adjust a speed ratio of an infinitely variable transmission (IVT) system. A speed ratio control for an IVT system involves a forward speed controller and a crank length controller for different speed ranges. The time-delay control is designed to reduce speed fluctuations of the output speed of an IVT with an accurate speed ratio. The speed ratio of an IVT with the disclosed control strategy can achieve an excellent tracking response for the desired constant output speed and reduce speed fluctuations of the output speed of an IVT by the time-delay feedback control.

  • Publication number: 20230181151
    Abstract: Disclosed is a system and method for the placement of elongate medical members within a patient’s body using coaptive ultrasound that combines magnetic guidance with ultrasound visualization of the medical member in the patient’s body. A coaptive ultrasound probe adaptor magnetically attracts an elongate medical member within the patient with sufficient force so as to allow the operator to manually guide the member to its intended location. The adaptor mates with an ultrasound probe to provide the medical operator ultrasound feedback of the position of the member, thus allowing internal placement without the need for more specialized medical equipment.

  • Patent number: 11672474
    Abstract: Provided herein are methods to predict pain sensitivity and pain intensity to prolonged pain in a subject. Electroencephalograms are recorded in a pain-free state or, alternatively, in a pain-free state and after applying a prolonged pain stimulus in a prolonged pain state. Pain-free and prolonged pain peak alpha frequencies or ?PAF are measured. These values correlate negatively with the likelihood of increased pain sensitivity and increased pain intensity. Also provided is a method for predicting a likelihood of chronic pain in a subject after a medical procedure and designing a plan to treat the chronic pain.

  • Patent number: 11638778
    Abstract: An oxygen supply unit for use with a blood oxygenator comprises an oxygen concentrator and a carbon dioxide scrubber. In an on-line operational mode, oxygen-rich gas from the oxygen concentrator is predominantly supplied to the blood oxygenator with a reduced flow of recycled gas from the concentrator. In an off-line operational mode where the oxygen supply unit is being powered by battery only, a larger flow of recycled gas from the blood oxygenator is passed through the carbon dioxide scrubber and combined with a lesser amount of oxygen-rich gas from the oxygen concentrator. The oxygen supply unit may be used in combination with a blood pump and oxygenator to provide ambulatory blood oxygenation to patients with compromised lung function.
