Using autocorrelation model for movement detection

Posted on Feb 14, 2018 | Comments Off on Using autocorrelation model for movement detection

We have noticed markable improvements in move detection in accelerometer signal when we tested autocorrelation model. It’s similar to autoregressive (AR) model, but in this article we call this model autocorrelation.

The autocorrelation is defined as:

Where N is the total window size, N win is the AR window size, i is the AR shift, and Ncor is the number of steps.

In tests we have noticed that autocorrelation works a lot better than other methods, including FFT., though it requires significant calibration and tuning. See the graphs with different move states below.

The final plot depicted below is the result of running movement detection using autocorrelation on live production data collected from one of our customers baby,

The three colored axis show row accelerometer signal and the dotted line shows detected movement in moves per minute. The bottom graph shows state enumeration with different movement classification states detected. A thing to note that no-move detection is corresponds to flag=-2, which is an alarming condition to alert parents. In the sample below, the alarm have not been detected.

Measurements of BLE signal indoors

Posted on Jun 21, 2016 | Comments Off on Measurements of BLE signal indoors

Measurements of BLE signal strength (RSSI) dependency on the range indoors

Introduction

There is not much results of Bluetooth Low Energy range measurements to be found on the web. The primary reason is that it’s hard to control for environment, wall and floor materials. That being said, the numerous use cases for Bluetooth LE, from now on BLE, exactly in that type of environment, indoors. We, at Mondevices, decided to fill that gap.

Description of Setup

We took various BLE devices that transmit packets about 10 times per second and varied antenna designs. Most of PCBs were based on TI chip CC254x family. We have also included a combination of CC2541 with a power amplifier CC2590 and also used Texas instrument RF Studio with a mounted antenna. Below is a detailed description of the devices used.

We have tried to find the best performing devices that could operate at furthers distances from the office and keep steady connection. We have found that TI RF Dev Kit and CC2590 booster are consistently perform better than other devices. TI Dev Kit has a large wave-length antenna and CC2590 boosts power transmission to 10 dbm, which is 4 times more than current chip antenna at 4 dbm setting or 8-9 times better than CC2541 0 dbm setting.

The photo of BLE range test setup describes positioning of all the test devices.

We tried all different combinations of antenna while trying to stay as close to same technology stack of TI CC254x family.

The close up of PCB with 1/4 wire antenna, CC2590 combo with MIFA and wire antenna.

Measurements

We have conducted measurement of RSSI strength of advertising packets of all 13 devices using TI Smart RF packet sniffer. We stored the results and parsed them with our custom parser script written in python. The results are attached as plots and tables.

Results

We did several measurements starting within in the same room in the office confines, then outside in the most RF challenging area of the kitchen and outside in the long corridor. The results of RSSI strength measurements of advertising packets are shown below. To avoid clatter on graphs we only display top three and top bottom plots. The tables shows stats for all

the devices. The kitchen area is very typical to every office and home, with metal surfaces of refrigerator, fax and printer machines and surrounding offices with BLE speakers, wearables and printers. Metal surfaces create destructive interference, where BLE signal interfere with itself. Other electronic devices create electromagnetic RF interferences. We counted around 200 BLE devices sending advertisement packets.

In the same room

In the office, same room where we placed all the devices, we can detect all the signals. This is an expected and obvious result. What is interesting that the biggest RSSI values we get from TI Dev Kit, CC2590 booster combo and, most surprising, just a simple vertical 1/4 wave length antenna positioned perpendicular to the PCB plane

The table below shows the stats for all the devices, not just top and bottom three. As one can see devices with power booster, CC2590, shows consistently on top.

As one can see the strongest signals are from CC2590 combo with and without WIRE antenna, and from CC2540 with WIRE antenna. The percentage of FCS errors that demonstrate the data loss is also the least in CC2590+CC2541 combo and in CC2540 with the WIRE antenna.

In the RF dead zone – the kitchen

The kitchen is one of the most challenging from RF interference perspective environments. Here  only a few devices survived.

The table below shows the stats for all the devices in the kitchen.

Again in the kitchen are the strongest signal and lowest errors are in CC2590 combos and in WIRE antenna.

When we tried to walk beyond the kitchen table we only observed CC2590 combo surviving the distance and kitchen interference with high rate of data errors.

In the long corridor

We also did measurements in the corridor far away from the kitchen we got slightly better results.

Not surprisingly the strongest signals and lowest FCS errors are from CC2590 combo with and without WIRE antenna, and from CC2540 with WIRE antenna.

Walking towards the advertising devices

The last test in this document we have walked from the area past the kitchen towards the advertising devices. Below is the graph that shows graphs and tables with RSSI values.

Just like in previous experiments, we can see that the strongest signals and lowest data errors levels are in CC2590 combos.

Conclusions

We have conducted experiments indoors using different antenna configurations and designs on CC254x IoT SoC technology.

We have consistently observed that the strongest signals that survived both RF interference and distance are

• CC2590+CC2541 combo
• WIRE antenna

Mondevices on ABC Shark TV

Posted on Dec 5, 2014 | Comments Off on Mondevices on ABC Shark TV

Last Friday December 5th, Mondevices were invited on an ABC Good Morning America show with Barbara Corcoran from Shark Tank show. We were selected to be one of 15 inventions to have a chance to pitch to Barbara. She chose a waffle maker who will have a one-on-one time with her, but Mondevices got very kind words from her and from the audience. Audience loved our product and was very encouraging. The whole episode had a Christmas theme and people were very cheerful and supportive.

This was the first time I was inside the studio and saw all inner workings of the morning show production. The studio is divided into sections. One section is being filmed while the other section is being prepared for the next segment. Cameras are located in the center of the room and easily rotated between the sections. During the switch the cameras are switched to the outside crowd or to pre-recorded video clips.

After the segment we were treated to an interview with Cameron Diaz. It was very interesting glimpse inside the workbench of TV studio.

Here are some pictures from the GMA show, unfortunately we could not make pictures inside the studio.

Monbaby on Fox News!

Posted on Nov 13, 2014 | 2 comments

Today Fox New aired a segment on Monbaby, you can view it here: smart-baby-monitor-aims-to-prevent-infant-deaths

There were couple of minor errors in the video. The accelerometer is not 140 bit, rather 14 bit. To a non-technical mind 14 bits is not much, that is unless it’s 2 to the power of 14.

Another corrections, Monbaby’s aim is to help parents to monitor their babies for unsafe conditions, such as sleeping on a stomach.

Other from those two minor errors, the video was an awesome chance for us to spread the word about the Monbaby. Huge thanks to Douglas Kennedy and his team and to Fox News Channel!
