IWR6843: [IWR 6843] URGENT HELP NEEDED ON USING DIRVER FATIFUE / SLEEP DETECTION

SRIRAMAN NC
Prodigy 30 points
Part Number: IWR6843

We are a Technology Start up company in india and we are designing MMWave radar solution with TI Chip for Driver Fatigue / Sleep / Drunk and drive detection
I want more details on the following
a. How the Heart Rate is computed ? is it done in the Demo Application or inside the DSP of the Chip?
B. If it is done outside can we get PQRST wave form gathering  of the code because we want to understand the R - Peak occurrence in the cycle and also the periodicity of the R Pulse ( for measuring Heart rate and the irregularity in heart rate
c. How do I use Heart Rate and Breathing pattern for Drunk and drive detection, Fatigue detection
D. How many patients Breathing rate and Heart rate a single Radar can detect? Are these measurement medical grade measurement?

E: Can the device detect heart rate and Breathing rate for multiple people ?

    HI, there:

    You can find the vital sign demo at industrial toolbox located at: dev.ti.com/.../node

    You can find brief introduction on the algorithm in the users guide. Yes, the heart beat is computed on-chip.

    Our radar device can only generate FMCW wave.  

    You can use this demo to start, and it is up to you to expand this demo to your specific application.  Right now, our demo is quite simple, it uses only on TX-RX pair, and the people has to face it directly.   I have seen other company use the device to detect vital sign for two front row people in the car.   But we do not have such a demo yet.

    Best,

    My fault.  We actually have a demo that combine two labs, Vehicle Occupant Detection and Driver Vital Signs, into a single application, and can detect the vital sign of the two people in front seat:

    Hi there

    Thanks for your response. We wiill go through the demo code and try to build on it .

    To do more detailed and intricate analysis of the vital sign we need to get the following

    a,. How the HEart rate is detected

    B. Can i get the ECG wave form built based on the dopler effect and accurately plot the PQRST wave forms. is there any APIs avaialble to extract the data from DSP and plot PQRST Waveform ourselves

    C. Do i have access to the DSP to find our the R Interval to identify the irregular heart beat

    I want to have conversation with your expert and understand the SDK what it does and how stabilization of the waveform is achieved

    Can you connect me to expert for a conference call

    We have a huge order for tracking the dirvers of vehicles from many companies and the immediate order potential of 3000 pieces and we need to show a demo POC to customer

    Request your help


    Regards

    Hi, Sriraman:

    a) The basic idea of the algorithm is explained at: dev.ti.com/.../node

    regarding (B) and (C), if you can not find the answer from the link in (a), then we do not have an answer. 

    Please contact the sales or field engineer in your area for next level of support.  Please let me know if you have problem reaching out to the local sales or field engineer.  

    Best,

    Zigang
