摘要: Systems and methods are described that enable sensing of magnetic fields within skin tissue. Specifically, a system includes one or more microneedles that include a high magnetic permeability material. The system also includes a magnetic sensor communicatively coupled to the microneedle and configured to detect a magnetic field proximate to the microneedle. The system also includes a controller configured to receive information indicative of a magnetic field proximate to a portion of the microneedle. The controller is further configured to determine a presence of at least one magnetic nanoparticle proximate to the portion of the microneedle based on the received information. Alternatively, other embodiments include a microneedle that includes a nanodiamond material configured to detect a local magnetic field. Such embodiments also include a light source configured to cause the nanodiamond material to emit characteristic emission light that may indicate at least a magnitude of the magnetic field.

摘要: A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment. In some embodiments, the system can further include a support surface having one or more sensors incorporated therein either in addition to sensors affixed to the patient or as an alternative thereof. The support surface is, in some embodiments, capable of responding to commands from the host for assisting in implementing a course of action for patient treatment. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capacitive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.

摘要: An apparatus comprises a magnetic field detection circuit, a cardiac signal sensing circuit, a memory circuit, a control circuit, and an arrhythmia detection circuit. The cardiac signal sensing circuit generates a cardiac signal representative of cardiac activity of a subject when coupled to sensing electrodes. The control circuit is operatively coupled to the magnetic field detection circuit; the cardiac signal sensing circuit, and the memory circuit. The control circuit stores cardiac signal data determined using the sensed cardiac signal, receives an indication of magnetic field detection by the magnetic field detection circuit, stores data obtained using the sensed cardiac signal during the magnetic field detection, and stores an identifier indicating the magnetic field detection in association with the data. The arrhythmia detection circuit processes the cardiac signal data to detect a cardiac arrhythmia event and confirm the cardiac arrhythmia event according to the magnetic field indication.

摘要: A method, system, and device for measuring and evaluating hair loss over time is disclosed. A instrumented comb device includes a power source, a controller, and associated sensors. The controller receives signals from the sensors, including a contact sensor to detect contact with a scalp and obtain a hair count, and a magnetic compass to determine location on the scalp. The controller includes one or more processors that acquire and record the detected contact information and determined location information as the comb device is stroked over a scalp, and measure hair density based on the contact information and location information. The instrumented comb can communicate with a remote information system or a mobile device for auxiliary processing and display. Machine learning of the remote information system allows for recognizing hair density or prediction of future trends in hair density over time using data recorded by the sensors.

摘要: Some implementations provide a method for safe operation of a magnetic resonance imaging (MRI) system, the method including: determining, at least in part by using a sensor device, location information that indicates a location of an MR-incompatible object relative to the MRI system, the MRI system generating a polarizing magnetic field for imaging a subject; based on the determined location information, determining, by a control unit associated with the MRI system, that the MR-incompatible object poses an operational hazard to the MRI system; and in response to determining that the MR-incompatible object poses an operational hazard to the MRI system, reducing, by the control unit, a strength of the polarizing magnetic field.

摘要: Disclosed is a motion digitizing and evaluating device, capable of preparing recordings or motion files more accurate—from several aspects—than those known so far, even without a permanent external reference signal. In addition to the inertial measurement units fixed to the separately moving body parts or spare parts of the examined person, living creature or objects, basic parts of the device are also the pressure-sensitive sole units and the pressure sensor gloves, thanks to which the location-changing movements can be truly tracked by the virtual bone system mapped by the software. With more accurate motion detection, the external magnetic orientation—which has so far been inevitable for such purposes in the previous systems—or the application of multi-axial magnetometers can be easily eliminated. A part of the patent is a strap vest for the more precise fixing of the strain-related sensors on the back.
