2Heart Rate Variability (HRV) Algorithm(While Resting or Active)

By using PPG and Acceleration signals, our algorithm can precisely measure HRV, the variation in time between each heartbeat.

Measuring HRV can objectively assess readiness, workload, and recovery status. An affordable and scalable solution for maintaining operational performance.

Our filters enable precise reconstruction of a PPG signals’ shape to detect systole peaks and calculate the time intervals between them, a solution for both at rest and daily life activities.

Accuracy <10% LF/HR error at all activities

We developed an HRV solution that works during any activity

Using PPG signals, and Acc for motion compensation

HRV can be used for stress assessment, sleep quality, and fitness recovery analysis

4Continuous Oxygen Saturation Algorithm(Oxygen Wrist Monitoring)

Can be implemented on any wearable device containing Red and IR PPG optical sensor.

With medical grade accuracy, the SpO2 algorithm, and the device implementing it, can be FDA or CE cleared.

Recursive reconstruction techniques enhance PPG signals, enabling the extraction of robust SpO2 from challenging body areas such as the wrist.

Accuracy is > 95% +/-3% compared to Nonin (based on 80 subject validation)

The Department of Health Services at UCLA validated our SpO2 algorithm by comparing it to a finger device cleared by the FDA as well as to blood samples.

The study involved 38 healthy participants aged 23-56 years, with oxygen saturation levels ranging from 100% to 70%, and the results showed a strong Pearson correlation coefficient of r=0.953.

5Continuous Cardiac Arrhythmia Detection(AFIB Alerts)

Our algorithm enables continuous monitoring of Atrial fibrillation (AFIB) on any type of wearable device containing a PPG optical sensor and an Accelerometer.

AF is usually detected using an ECG monitoring. ECG is a non-continuous approach and requires the user to actively place his other hand on the watch\ ring face.

By using a PPG only, we allow a continuous and unobtrusive monitoring solution.

Accuracy The AF detection overall accuracy is: 0.962, AUC: 0.998, AF specificity: 0.974, AF Sensitivity: 0.931

We’ve collected more than 430 sessions of synced PPG and ECG signals with various cardiac arrhythmias.

Our first ready app is AF detection. In the next release we will also be able to detect other cardiac arrhythmias.

SLEEP ANALYSISNohayo's advanced sleep tracking algorithms are capable of precisely monitoring the various stages of your sleep, evaluating its quality, and identifying instances of obstructive sleep apnea (OSA), all through the use of a wristwatch or finger ring only

Sleep Stages(Rest Easy)Download brochure

Our algorithm will change the way we understand sleep and facilitate the way in which we monitor it.
The Light, Deep and Rapid Eye Movement (REM) sleep stages are necessary cycles to feel fully rested.
Our algorithmic solutions break these stages down to easily identify problems or patterns to quickly resolve the issue and attain better sleep.

Obstructive Sleep Apnea (OSA) Algorithm(A Wake-up Call)Download brochure

Used with any type of wearable device with PPG optical sensor and Accelerometer Sensor to detect OSA night events.
Allow OSA detection at home by simply wearing an equipped watch or ring.
The algorithm processes the PPG, SpO2 and Acceleromter signals to detect Apnea events in real-time.
Our algorithmic solution can simply inform the user about the OSA events, or gently wake up the user when an OSA event occurs, dramatically improving sleep quality.

1Physical Activity Classification(Stay Fit, Stay Well)

Used in fitness

Used in fitness monitoring, wellness, diet regimes, etc.

Enables uninterrupted classification of a user's actions

Walking, Running, Cycling, Sleeping, Office Work, Gym, Swimming.

Detects real-time activity

Detects real-time activity based on both time domain and frequency domain features extracted from the 3D Accelerometer and HR Sensors.

2Ground Contact time (GCT)(A Runner’s Advantage)

GCT measures time foot is on the ground when running, NO foot pod required!

Footstrike time from stance to toe-off for each stride while running.

GCT measures time foot is on the ground when running, NO foot pod required!

GCT is the key factor in running economy, an indicator of efficient expansion of energy when running.

GCT

GCT is traditionally measured by wearing a shoe pod, or chest strap. Nohayo’s new algorithm measures GCT using only a wearable device on the wrist\ finger\ and ear with 3D Accelerometer Sensor.

3Running Power(A Runner’s Winning Strategy)

Running Power

Monitoring every segment of a run is a phenomenally useful metric, whether running on flat or uphill terrain.

A measurement, in Watts, of how much work you're putting in while you run, NO foot pod required!

Running Power measures the amount of force and speed a runner exerts at any given moment.

3D Accelerometer Sensor and GPS

Traditionally measured with a shoe pod, or chest strap, Nohayo’s new algorithm uses a wearable device on the wrist\ finger\ and ear with 3D Accelerometer Sensor and GPS.

4Running Vertical Oscillation(Run Efficiently, Run Smart)

Running Vertical Oscillation

Reflects the efficiency of a running stride.

The amount that the torso moves vertically with each step, while running, NO foot pod required!

When running, Vertical Oscillation (VO), is a measure of vertical movement during each stride, and a key Running Dynamics metric.

Running Vertical Oscillation

Too much vertical oscillation means higher ground impact when landing and can increase injury risk. Less VO indicates low running performance. Measured on a wearable device on the wrist\ finger\ and ear. No waist pod or chest strap needed!
