A system for monitoring a joint of a user includes: a goniometer device for measuring an angle of the joint, and a pedometer removably attached to the goniometer device and configured to count a number of steps taken by the user. The goniometer device includes: a center hub, a first arm attached to the center hub, and a second arm attached to the center hub. A pedometer device for detecting steps taken by a user includes: a body and a circuit board including one or more sensors for detecting motion. The body is configured to be removably attached to a peripheral device by a magnetic coupling.

A system for measuring an angle of a joint of a user includes a coupling apparatus configured to be adhesively attached to a limb portion proximal to the joint of the user, and a goniometer device. The goniometer device includes: a center hub, a first arm having a first inner end attached to the center hub and a first outer end opposite the first inner end, and a second arm having a second inner end attached to the center hub and a second outer end opposite the second inner end. The first outer end of the first arm is removably attachable to the coupling apparatus by a magnetic attachment.

The present invention relates to methods for marking positions for or for positioning of six ECG chest electrodes based on a subjects body height, which allows a reproducible placement of the electrodes in serial independent ECG measurements. The present invention further relates to a device for placement of ECG electrodes which implements said method, and methods and uses applying said device. Hence, the present invention provides an accurate and reproducible, easy to use and low-cost method and device for ECG chest electrode positioning, especially in serial examinations and in obese subjects by minimizing the mistakes in ECG chest electrode placement depending on the subjective and inaccurate defining of anatomic remarks for electrode positions.

The present disclosure relates to injectable compositions sterile injectable fluid compositions comprising a polysaccharide having a color in the visible spectrum, methods of forming the same, kits containing the same, and methods for performing agent-assisted procedures in a patient using the same.

A method for operating an accessory device to capture calibration data. The method can include capturing an image of a portion of a user's body that includes the user's stoma and at least two reference locations, and storing distance scale information representative of a distance between the two reference locations. The method further includes processing the captured image, including: identifying the reference locations, identifying the stoma, and generating calibration data representative of one or more stoma parameters as a function of the identified reference locations, identified stoma and the distance scale information. The calibration data can be stored.

A method for training an artificial intelligence (AI) model for allowing a user to intuitively control an electronic device includes positioning a plurality of sensors at a plurality of particular positions on a human body for sensing electric signals. The method also includes recording a first set of electric signals from each of the plurality of sensors in a continuous manner. At the same time, a first set of motion intents associated with a first sequence of body movement is also recorded in a continuous manner. An AI regression model is trained using a neural network to map the first set of electric signals to the first set of motion intents. In response to receiving a second set of electric signals from the plurality of sensors in a continuous manner, the AI regression model predicts a motion intent, causing the electronic device to perform an action.
