Abstract: A smart stethoscope includes: a main body including a plurality of sensors for measuring a user's bio-signals and a power supply unit; and a fixing part coupled to a front side of the main body and provided to be foldable to fix a user's finger, wherein the main body includes: an input unit operated by a user; and a control unit that, when one of measurement modes is selected by the user's operation, measures a bio-signal at a specific sensor from among the plurality of sensors on the basis of the selected measurement mode, and calculates a measurement value corresponding to the measured bio-signal according to a preset algorithm. Accordingly, auscultation can be optimized for a user by changing a measurement frequency by changing the mode according to the user while allowing for auscultation through multi-channels including electrocardiogram, pulse waves, and heart and lung sounds.

Abstract: A patient monitor can diagnose whether its speaker is blocked, malfunctioning, or at a volume that is too low. For example, the monitor can include a processor that can diagnose the speaker by recording a microphone input signal. The processor can compare the microphone input signal to an expected alarm signal that should be output by the speaker. If the two do not match or reasonably correspond to one another, then the processor may increase the volume of the alarm to determine whether doing so can overcome an obstruction, noise, or potential malfunction. The microphone can again detect the speaker output, and the processor can again make another comparison or analysis of the input with the speaker output. If the speaker output as detected via the microphone is still insufficiently loud, then the patient monitor may output an indication that the speaker has a problem.

Abstract: A patient monitor can noninvasively measure a physiological parameter using sensor data from different measurement sites on a patient. The patient monitor can combine all sensor data from different measurement sites into a raw or minimally processed data form to generate a single, robust measurement of the physiological parameter. An optical sensor of a patient monitor can include multiple photodetectors each configured to generate a signal when detecting light attenuated by the patient's tissue. A measurement of a physiological parameter can be determined based on at least in part on the multiple signals from the multiple photodetectors.

Abstract: Systems and methods of optical transcutaneous oxygenation monitoring. The oxygenation monitor comprises a photoluminescent oxygen-sensitive probe, a photon source positioned to direct photons at the probe, a photodetector positioned to detect light emitted from the probe when the photon source directs photons at the probe, a controller in electrical communication with the photon source and the photodetector, the controller being configured to execute a program stored in the controller to calculate a level of oxygen adjacent the probe from an electrical signal received from the photodetector. The photon source, the photodetector, and the controller are disposed in or on a support structure.

Abstract: This application relates to earbuds configured with one or more biometric sensors. At least one of the biometric sensors is configured to be pressed up against a portion of the tragus for making biometric measurements. In some embodiments, the housing of the earbud can be symmetric so that the earbud can be worn interchangeably in either a left or a right ear of a user. In such an embodiment, the earbud can include a sensor and circuitry configured to determine and alter operation of the earbud in accordance to which ear the earbud is determined to be sitting in.

Abstract: In at least some embodiments, the present disclosure describes an electroencephalography (EEG) device having a main band and at least one moveable band. The main band may include fixed EEG sensors positioned on the main band so as to contact a scalp of the wearer in at least two scalp zones. The at least one moveable band may include at least one moveable EEG sensor. The moveable band may move relative to the main band to adjust to a position of the moveable EEG sensor(s) on the scalp of the wearer in at least one adjustable zone. The EEG device may include a processing device to measure EEG measurements using the fixed and/or movable EEG sensors, and transmit the EEG measurements to an external computing device to determine a mental condition, a mental state or both of the wearer based on the EEG measurements.

Abstract: In embodiments, a Wearable Cardiac Defibrillator (WCD) system is configured to be worn by an ambulatory patient. The WCD system includes a main user interface (UI) output device that can output an image, sound or vibration as a main message about a condition of the patient or the WCD system. The patient may further carry a peripheral device that can also output an image, sound or vibration as a peripheral message about the condition. The peripheral message may mirror the main message at least in part, amplify it, and so on. The availability of the peripheral message provides the patient with the opportunity to better perceive the main message, and the flexibility to receive and react to it discreetly, learn more about the condition, and so on.
