A flexible head probe and modular head probe system that includes an optical functional near-infrared spectroscopy (fNIRS) system and integrated position sensor. The head probe and modular head probe system determines physiological data based upon the optical information gathered by the fNIRS system and gathers motion and position data from the position sensor. The physiological data and motion and position data are combined to permit topographical and tomographic analyses of a user's brain tissue.

Sensor apparatuses, methods of operating the sensor apparatuses, and systems including the sensor apparatuses are disclosed. Methods of analyzing electromechanical characteristics of a heart are also disclosed.

Provided are foldable electronic device and method for estimating bio-information by using the same. The foldable electronic device may include: a main body part including a first main body and a second main body that are configured to be folded toward each other or unfolded from each other along a fold line where the first main body and the second main body meet; an image sensor part including a first image sensor and a second image sensor which are disposed at the first main body; and a processor configured to obtain a contact image of an object from the first image sensor disposed at the first main body and obtain an image of a marker that is displayed on the second main body, from the second image sensor disposed at the first main body, when the object is in contact with the first image sensor and the main body part is folded along the fold line, and estimate bio-information based on the contact image of the object and the image of the marker.

A wearable device configured to monitor physiological parameters of a wearer can include: a physiological parameter measurement sensor configured to monitor a plurality of physiological parameters; a hardware processor; a display in communication with the processor; and a band configured to secure the physiological parameter measurement sensor on a wrist of the wearer. In some implementations, the hardware processor is configured to: obtain a first plurality of signals from the physiological parameter measurement sensor when the band is secured on the wrist at a first tightness; determine a signal quality responsive to the first plurality of signals; and output an indication on the display to adjust tightness of the band with respect to the wrist from the first tightness to a second tightness based on the determined signal quality.

A chest tube insertion test device for performing a chest tube insertion training procedure at least partially encloses an insertion tool and includes a microcontroller communicatively coupled to one or more force-sensing resistors. The one or more force-sensing resistors convert an insertion force into a voltage signal sent to the microcontroller. A feedback generator compares the chest tube insertion force to one or more predetermined threshold values and provides feedback to a trainee. The feedback can include an instruction to increase, decrease, or maintain the chest tube insertion force. The feedback is one or more audio cues and/or one or more visual cues (e.g., represented by audio files and/or visual data files stored at the chest tube insertion test device). The chest tube insertion test device detects an insertion force rate of change indicating that the insertion tool has passed through an inner pad of the training model.

A stimulation probe device including a first electrode, a stimulation module, a control module and a physical layer module. The stimulation module is configured to (i) wirelessly receive a payload signal from a console interface module or a nerve integrity monitoring device, and (ii) supply a voltage or an amount of current to the first electrode to stimulate a nerve or a muscle in a patient. The control module is configured to generate a parameter signal indicating the voltage or the amount of current supplied to the electrode. The physical layer module is configured to (i) upconvert the parameter signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the stimulation probe to the console interface module or the nerve integrity monitoring device.

An electronic device is provided. The electronic device includes a lighting-emitting diode (LED) module configured to emit light of a first polarization direction, a first photodiode configured to receive the light emitted from the LED module through a first polarizer having the first polarization direction, a second photodiode configured to receive the light emitted from the LED module through a second polarizer having a second polarization direction perpendicular to the first polarization direction, and a processor configured to determine wearing information of the electronic device based on luminous intensity of light sensed from each of the first photodiode and the second photodiode.

Described herein are functionalized garments that can be worn on the torso of a subject and can be configured with varying zones or areas of compressions and can provide increased signal-to-noise ratios and reduced motion artifacts in areas while allowing a substantially unimpeded freedom of motion.

An electroencephalography (EEG) headset can include an arrangement of straps that provides the ability to adjust the size and shape of the headset once disposed on a user's head. In some implementations, the headset can include a first elastic strap extending from a first side of the headset to a second side of the headset along a topside of the headset. The headset can also include a second strap including at least one inelastic portion and at least one elastic portion, at least one EEG electrode coupled to the second strap, a third elastic strap extending from the first side of the headset to the second side of the headset along an underside of the headset, and a plurality of connectors that couple the elastic first strap, the second strap, or the third elastic strap.

There is provided a physiological detection device including a light source, a light detector, a processing unit and a display device. The light source emits light to illuminate a skin surface. The light detector receives the light from the skin surface to output detected signals. The processing unit confirms an attached state according to the detected signals and controls the display device to show an indication signal or a warning message when the attached state is confirmed not good.
