  • Patent number: 11660223
    Abstract: A smart knee brace including a knee brace, multiple thigh bands, multiple shin bands, and multiple brace straps removably attached to one another and multiple motion actuators and sensors. Each motion actuator is connected to one brace strap and each sensor is connected to one motion actuator to measure an orientation of corresponding brace strap and generate a motion signal. A computing device receives the motion signals from the sensors; measures a current range of motion of the thigh, the shin, and the knee, and, based on the received motion signals, and generates drive signals based on the measured current range of motion. A native smart knee brace computer application on a smart phone of the user is operatively connected to the computing device and a cloud application server provide higher level analysis of the motions of the smart knee brace.

  • Patent number: 11657504
    Abstract: Systems and methods include a reduced computation, computer-based management of point-of-care (POC) on-site ultrasound (ULS) imaging resources. At a digital computation resource of a POC site, a ULS tissue reflection sample data is received from a hand-held ULS scanning device. A digital computation resource of the POC site, applies a reduced computation tissue ULS reflection speckle noise (SN) physics model—blurring noise (BN) physics model based deep learning (DL) trained convolutional neural network (CNN) denoising process to the ULS tissue reflection sample data outputting an estimated denoised ULS tissue reflection image data. A visual rendering of the estimated denoised ULS tissue reflection image data is displayed on a display resource of the POC site.

  • Patent number: 11642067
    Abstract: Examples include receiving and storing samples of target frequency bands filtered from EEG measurement of a subject's brain waves in an NFB training session. In an example, upon storing a time window of the samples, unsupervised adaptive adjusting an NFB reward threshold is automatic. The adjusting includes, in examples, determining neuromarker values in the time window, which indicate peak values of the target frequency bands over the time window. The adjusting computes the mean value of the neuromarker values and, utilizing same, automatically proceeds to unsupervised computing an adaptive adjusted reward threshold. The unsupervised computing, in examples, includes a multiplication product of a reward threshold adjustment factor, a training protocol value, and the computed mean value of the neuromarker values. Examples proceed to communicating the adaptive adjusted reward threshold to a controller for threshold based feedback reward to the NBF subject.

  • Patent number: 11607449
    Abstract: A synthetic DNA vaccine against SARS-CoV-2 infection comprises a codon-optimized coding sequence for optimal mammalian expression of a pSARS2 spike glycoprotein (pSARS2-S). The signal peptide may be replaced with the signal peptide from the human IgG2 heavy chain. Systemic S1-specific IgG antibodies and neutralizing antibodies (nAbs) were significantly induced in mice at 2 weeks-post three injections with 100 ?g of the pSARS2-S vaccine via intramuscular (IM) needle injection. IM immunization induced Th1-skewed and long-lasting IgG response in BALB/c mice. Immunogenicity and induction of nAbs were enhanced with a needle-free delivery system, wherein two doses were sufficient to elicit significant levels of systemic S1-specific IgG antibodies and nAbs via IM or intradermal immunization.
