Eyewear apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as EOG and ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.

In an example, the technique also detects and measures vital signs of each human target by continuous, non-intrusive method. In an example, the vital signs of interest include a heart rate and a respiratory rate, which can provide valuable information about the human's wellness. Additionally, the heart rate and respiratory rate can also be used to identify a particular person, if more than two target humans living in a home. Of course, there can be other variations, modifications, and alternatives.

Methods, apparatuses, and systems for maintaining and controlling surgical tools are disclosed. For each surgical tool, a surgeon can give verbal commands which can result in feedback provided by a synthesized voice or the execution of an action as instructed by the verbal command. The tools are monitored during use to ensure the tools remain within their operating parameters. The system alerts the surgeon should the tools approach their operational limitations.

The present invention relates to a method for monitoring a heart rate in a sleep state based on a microwave radar. The method includes: controlling the microwave radar to send a first detection signal to the human body when the microwave radar detects that the human body is not moving, and extracting a respiration waveform signal from the returned first detection signal; comparing the similarity of the respiration waveform signal and at least one respiration waveform signal standard sample in a sleep state in a preset respiration waveform signal database to obtain a similarity comparison result; determining that an object to be detected is currently in the sleep state and controlling the microwave radar to send a second detection signal to the object; and extracting a heart rate waveform signal from the returned second detection signal, and calculating a heart rate according to the heart rate waveform signal.

Earphone apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.

Equipment for carrying out cardiac autonomic neuropathy tests includes a base unit to which a mouthpiece is connected, forming an autonomous system for measuring the pressure and/or the pattern of breath, provided with a series of LEDs aimed at informing a patient, who is undergoing the test, about correctness or incorrectness of a test execution. The mouthpiece is provided with a flow sensor, aimed at measuring a patient's pattern of breath, and a pressure sensor. The mouthpiece includes also an atmospheric pressure sensor aimed at measuring the environmental pressure. The equipment includes also a sensor, aimed at measuring the heartbeat, applied by simple contact to the patient's wrist area, and an orthostatic measuring device aimed at measuring any change of the patient's position. Data can be introduced or analysed and the type of exam to do can be selected. Results of the tests can be stored in a memory.

An infant warming system comprising a platform for supporting an infant, at least two chest electrodes configured to connect to and detect cardiac potentials from a chest of the infant, an ECG monitor configured to receive the cardiac potentials from the at least two chest electrodes and determine a heart rate based on the cardiac potentials, a pulse oximeter device configured to determine an SpO.sub.2 for the infant, and a processor configured to compare the heart rate for the infant to a first heart rate threshold and compare the SpO.sub.2 for the infant to a first SpO.sub.2 threshold. The processor can also adjust a display of the heart rate and the SpO.sub.2 on a display device based on the comparisons and generate a first care instruction via a user interface based on the heart rate, the SpO.sub.2, or a combination thereof.

A method and apparatus for the treatment of Sleep Apnea events and Hypopnea episodes wherein one embodiment comprises a wearable, belt like apparatus containing a microphone and a plethysmograph. The microphone and plethysmograph generate signals that are representative of physiological aspects of respiration, and the signals are transferred to an imbedded computer. The embedded computer extracts the sound of breathing and the sound of the heart beat by Digital Signal Processing techniques. The embedded computer has elements for determining when respiration parameters falls out of defined boundaries for said respiration parameters. This exemplary method provides real-time detection of the onset of a Sleep Apnea event or Hypopnea episode and supplies stimulation signals upon the determination of a Sleep Apnea event or Hypopnea episode to initiate an inhalation. In one embodiment, the stimulus is applied to the patient by a cutaneous rumble effects actuator and/or audio effects broadcasting.

A test system for detecting impairment aboard a motor vehicle includes an electronic control unit (ECU) and sensors in communication therewith. The sensors are positioned within a vehicle interior, and include at least a touch screen and a microphone, and possibly an eye-tracking camera. In response to receiving a start request indicative of a requested start event of the motor vehicle, the ECU executes instructions to initiate a cognitive response test via the sensors. The ECU determines a test score of a driver during the test while the motor vehicle remains off, compares the test score to baseline scores to determine a passing or failing test result, and executes a control action aboard the motor vehicle in response to the passing or failing test result. The ECU may disable or immobilize the motor vehicle in response to the failing test result.
