  • Publication number: 20200315530
    Abstract: A monitoring apparatus for a human body includes a node network with at least one motion sensor and at least one acoustic sensor. A processor is coupled to the node network, and receives motion information and acoustic information from the node network. The processor determines from the motion information and the acoustic information a source of acoustic emissions within the human body by analyzing the acoustic information in the time domain to identify an event envelope representing an acoustic event, determining a feature vector related to the event envelope, calculating a distance between the feature vector and each of a set of predetermined event silhouettes, and identifying one of the predetermined event silhouettes for which the distance is a minimum.

  • Publication number: 20200129167
    Abstract: A method for creating space in a joint formed at the convergence of two bones, the method comprising: applying force to a body part so as to separate the two bones from one another by a distance which is greater than the distance that they are normally separated from one another when the joint is in a healthy state, whereby to distract the joint and create an intrajoint space; inserting an assembly of three balloons into the intrajoint space while the assembly of three balloons is in a contracted condition; expanding the assembly of three balloons within the intrajoint space; and reducing the force applied to the body part so that the joint is supported on the assembly of three balloons, with the two bones remaining separated from one another by a distance which is greater than the distance that they are normally separated from one another when the joint is in a healthy state.

  • Publication number: 20190290189
    Abstract: A handheld, conforming capacitive sensing apparatus configured to measure Sub-Epidermal Moisture (SEM) as a mean to detect and monitor the formation of pressure ulcers. The device incorporates an array of electrodes which are excited to measure and scan SEM in a programmable and multiplexed manner by a battery-less RF-powered chip. The scanning operation is initiated by an interrogator which excites a coil embedded in the apparatus and provides the needed energy burst to support the scanning/reading operation. Each electrode measures the equivalent sub-epidermal capacitance corresponding and representing the moisture content.

  • Publication number: 20190231434
    Abstract: A method for visualizing at least one region of a joint that deviates from a baseline anatomy includes receiving image data associated with a joint of a subject, generating a three-dimensional model of at least a portion of the joint using the image data, identifying at least one region of the joint that deviates from the baseline anatomy by comparing the three-dimensional model to a baseline model, generating a measurement of a characteristic of the joint at one or more predefined locations using the three-dimensional model and a coordinate system, and generating a three-dimensional rendering of the model that includes a visual indication of the at least one region of the three-dimensional model that deviates from the baseline so that the region is visually indicated according to degree of deviation, and a representation of the measurement of the characteristic of the joint that is positioned according to the predefined locations.
