Kyoto University and Panasonic Corporation have revealed today a new technology they’ve been working on together, which enables remote detection of vital signs.
Heart rate, heartbeat intervals and other such vital signs will soon be measured without placing sensors on the body, fact that can be quite stressful, especially for young people. Arrhythmia resulting from such stress could be misinterpreted as a genuine heart problem, and patients could end up taking a treatment for a disorder they don’t actually have. Researchers at Panasonic and Kyoto University have created a technology based on a high sensitive spread-spectrum radar and feature-based heartbeat interval estimation algorithm that rivals electrocardiographs in accuracy.
“Taking measurements with sensors on the body can be stressful and troublesome, because you have to stop what you’re doing,” explained Hiroyuki Sakai, a researcher at Panasonic. “What we tried to make was something that would offer people a way to monitor their body in a casual and relaxed environment.”
Panasonic and Kyoto University are trying to promote casual sensing, which means that people who are at risk of heart conditions could have their vital signs checked in the safety of their home, without having to pay healthcare professionals a visit. In fact, the radar developed by the two institutions could be triggered each night before going to bed, or each morning, right after waking up, and the patients wouldn’t be the wisest.
“Heartbeats aren’t the only signals the radar catches. The body sends out all sorts of signals at once, including breathing and body movement. It’s a chaotic soup of information,” added Toru Sato, professor of communications and computer engineering at Kyoto University. “Our algorithm differentiates all of that. It focuses on the features of waves including heart beats from the radar signal and calculates their intervals.”
According to the researchers, the remote sensing system brings together millimeter-wave spread-spectrum radar technology and a unique signal analysis algorithm that can accurately identify signals from the body. Needless to say, the team who has developed this hopes that the system will be available in the near future.
“Now that we know that remote sensing is possible, we’ll need to make the measurement ability more robust so that the system can monitor subjects in various age ranges and in many different contexts,” concluded Sato.
This technology may not seem like a major advancement, but anything that helps patients be less stressed when their health needs to be assessed should be appreciated. It should be noted that Panasonic and Kyoto University are not the only ones interested in such a tech, as researchers at China’s Fourth Military Medical University and NASA have each expressed their interest on this matter. However, the radars developed by these two were built with rescue missions in mind, while Panasonic’s serves an entirely different purpose. That’s not to say that their radar couldn’t be repurposed.

VPN services are good not only for allowing us to circumvent geographical restrictions imposed by content providers, but also for keeping us safe online by routing all of our traffic through a server from an entirely different location than ours.
Now that there are VoIP apps such as Aznog that offer free direct calls to mobile and landlines, finding a free Wi-Fi network while traveling may seem like a give from above (well, it quite literally is, unless the router is located below you). However, public Wi-Fi connections may be used by hackers as a bait for getting sensitive information off the mobile devices that are accessing the said networks. Identity theft is only one of the bad things that could happen while using a free Wi-Fi network.
Browsing the Web on our smartphones or tablets has become one of our favorite pastimes, and while doing so, we happen to stumble upon things we’d like to buy. Has one of your wishlist items gotten an unprecedented discount while you’re browsing the Web on a public Wi-Fi network? Then it’s time to input your credit card details and wait for that particular item to be delivered to you, but not before using a VPN service to make sure that your sensitive data stays safe. BitVPN has several different uses, and protecting your privacy is only one of them.
Needless to say, BitVPN can also be used for accessing geo-blocked content. Even though Netflix doesn’t see VPN services with good eyes, and has even announced a couple of days ago that it intends to block them, these can still be used for streaming movies and TV shows while traveling. As in the previous scenario, all traffic will go through 256-bit encryption, and your IP address will be hidden from hackers and spies. There are no limits to your bandwidth, so you don’t have to imagine Web pages taking ages to load, or video content buffering all the time.
Listed below are the VPN protocols (one account for multiple services) supported by BitVPN.
Moreover, BitVPN offers access to 40 servers from the 11 countries listed below:
Once you buy a BitVPN license on Walyou Deals, you have to redeem it within 30 days. The license includes updates for the entire duration of the subscription. BitVPN can be used on up to 3 devices, but if you’re planning to use it at home, as well, I would suggest adding it to your Wi-Fi router’s settings, so that all of the devices behind it are seen as one.
In our store, the lifetime subscription to BitVPN can be purchased for $34.99, which is 82% less than what it typically retails for. The deal expires in two days, so if you care about your privacy, you should take advantage of it while you still can!
