  • Patent number: 11859716
    Abstract: A tidal current energy converter including an infinitely variable transmission (IVT) control system and a hybrid vertical axis wind (or water) turbine (VAWTs) apparatus. The hybrid VAWT apparatus includes a modified-Savonius (MS) rotor in the central region and a straight bladed H-type Darrieus rotor in the surrounding annular region. The IVT control system includes a nonlinear closed-loop control combined with an integral time-delay feedback control to adjust a speed ratio of the IVT. A speed ratio control for an IVT system involves a forward speed controller and/or 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.

  • Patent number: 11850441
    Abstract: Disclosed is an electromagnetic coil system for use during transcranial or transdermal stimulation procedures, in which an electrically conductive coil wraps around a magnetic core at an oblique wrapping angle to provide a more directed focal spot size at a given depth inside of, for example, a patient's body. In certain configurations, the electrically conductive coil may be adjustable with respect to the magnetic core, such that the wrapping angle of the electrically conductive coil may be modified to, in turn, adjust the focal spot size of the induced electric field generated by the system as may desired to concentrate the field at a particularly desired location.

  • Patent number: 11846633
    Abstract: Seroprotection analysis systems, kits, and techniques are described for testing oral fluid for the presence of protective levels of antibodies of interest. In one aspect, the presence of protective levels of target antibodies indicates a test subject has achieved a target seroprotection level, such as but not limited to a target seroprotection level following vaccination. A collection kit can include a swab that enables collection of oral fluid containing antibodies from both dentulous and edentulous individuals, a container that can be pre-filled with an extraction solution, and a nozzle that can be coupled to the container to form a fluid-tight device. A user can use the nozzle to seal the swab in the container and to compress the swab within the container.

  • Patent number: 11833256
    Abstract: The invention relates to compositions and methods as part of a pharmacotherapeutic strategy that targets the endochondral ossification process in a pharmacologically selective and site-specific manner. A variety of orthopedic pathologies are caused by or associated with generalized or local dysregulation of endochondral ossification, for example trauma to the bone growth plate or diaphysis can cause a serious imbalance in bone growth, leading to progressive deformity that today can only be treated surgically. Dysregulated endochondral ossification is also behind heterotopic ossification, which arises in soft tissues and causes pain, decrease in mobility and other clinical problems. The invention therefore provides RARy agonist and antagonist nanoparticle compositions for treating abnormal endochondral ossification and bone growth that can deliver robust local therapeutic control over a particular long bone's growth with a long-lasting effect.
