Frequently Asked Questions

My speaker is not generating any sound, what should I do?

If your speaker is not working, we suggest the following troubleshooting steps:

Open up NVIDIA® GUI to see which peripherals are enabled, type the following into the command line:sudo /opt/nvidia/jetson-io/
Ensure that the i2s5 is enabled. If not, Configure 40-pin expansion header and enable i2s5. You will be prompted to save and reboot.

Once your device has been rebooted, be sure to configure the soundcard appropriately with the following command:amixer -c jetsonxaviernxa sset "I2S5 Mux" ADMAIF2

Finally run a speaker test with this command:
speaker-test -D hw:jetsonxaviernxa,1 -c 2 -r 48000 -F S16_LE -t sine -f 500

My Microphone isn’t recording anything, what should I do?

If you are struggling to record with your microphone, follow these steps:

The I2S peripheral which connects to the microphones is constantly running, there is no need to address that.

Reconfigure the sound card subdevice appropriately with the following command:amixer -c jetsonxaviernxa cset name='ADMAIF1 Mux' I2S3

Record using the following command:
arecord -D hw:jetsonxaviernxa,0 -c 2 -d 10 -r 48000 -f S32_LE test.wav

What is a semantic search engine and how does it differ from a traditional search engine?

While a traditional search engine deciphers queries based on keywords or short strings of words, a semantic search engine takes a more holistic approach, considering what the words mean and how they relate to one another. CastleBravo enables users to search through a large set of images/videos at the same time and returns image results that match their queries.

How many videos can CastleBravo search at once?

CastleBravo search does not have a limit on the number of videos it can search at once because the videos are indexed with GraphDB. With this approach, you can search through thousands of videos at the same time.

Is there a format to follow for the search queries to work? Would it affect the accuracy of the search results?

No, the search engine, like any semantic search engine, enables users to search through his or her own query structure. Also, users can refine their queries to get more specific results.

EDGAR Health Suite

What is healthcare data analytics?

Healthcare analytics is the study of current and historic industry data to predict trends, improve outreach, and manage the spread of diseases. EDGAR can mitigate the spread of disease in cases where there are lapses in preventive actions (for example, using masks). 

What role does data analytics play in healthcare?

EDGAR analyzes data to detect incorrect performances of preventive public health actions (e.g. not wearing a mask in areas where it is mandatory). The application then assesses the severity of the infraction and notifies the user through a dashboard. Throughout the process, EDGAR keeps all data encrypted and protected.
