ICMe Cuffless Finger Blood Pressure Monitor Sends Results to your Smartphone via Bluetooth 4.0

Nihon University have developed a tiny blood pressure monitor, which you can just touch with your finger, in order to get maximum and minimum (systolic and diastolic) blood pressures,  both average and real-time values, as well as pulse rate and pulse waveform displayed on your smartphone. ICMe uses photo transistors to detect LED light reflected on a finger, and then converts pulse wave data obtained from the light to a blood pressure value. Phase Shift Method-based data processing and algorithm is used for the conversion to a blood pressure value, and results are transmitted to the phone via Bluetooth 4.0 (LE?). The device is composed of a custom main chip, LEDs, photo transistors, and a Bluetooth 4.0 module. Tech-on reports an early much larger model was exhibited last year at Medica 2013, and the new miniaturized model is currently showcased at Medica 2013, which runs from Nov 20 to 23, […]

Coin is a Smart Card that Replaces All Your Other Cards (Credit, Debit, Loyalty…)

You may have a few cards in your wallet: credit cards, debit cards, gift cards, membership cards, … and it’s just convenient to carry them around all the time. There will soon be a solution with Coin, a smart card where you can store all your other cards data, and use this smart card instead. In order to register your physical cards (up to 8 cards for one Coin), you’ll need to install an application in your Android smartphone, or your iPhone, take a picture of both sides of the cards, and swiping the Coin though a small device provided with the card. Then, when you want to make a purchase, you just click on the button of the Coin to select the card to use, and carry on with your purchase are you would normally do. You may worry about security concerns, but the company behind the Coin has […]

Ninja Sphere Home Automation and Monitoring Platform

Ninja Blocks is an company providing open source hardware solutions for home automation. Their first product was called Ninja Blocks Kit which includes a Ninja Block (Beaglebone + Arduino based gateway, but they now also support the Raspberry Pi), sensors, sockets, cables, and a power supply, and works with Ninja Platform, an open source software framework. The goal was to simplify the process of developing automation applications by taking care of all low levels tasks such as electronics, embedded programming, network protocols.., and letting “end users” / developers focus on their application. The company is now working on a new version called the Ninja Sphere, including a “Spheramid” gateway, location waypoints (Bluetooth low energy tags), and smart power sockets. Here are the key features of the gateway: Processor – ARM Cortex A8 (probably Texas Instruments Sitara) Color LED Matrix Connectivity – Bluetooth, Bluetooth LE, Zigbee, and Wi-Fi USB Port – […]

LinuxCon Europe 2013 Schedule – Web Technologies, Debugging Techniques, Wayland, and More

I’ve just received an email from the Linux Foundation saying the schedule for LinuxCon and CloudOpen Europe 2013 had been made available. The conference will take place for 3 days (October 21-23, 2013) in the Edinburgh International Conference Center, Edinburgh, United Kingdom. There will be over 100 conference sessions, and several co-located events including: Automotive Linux Summit, the Embedded Linux Conference, Gluster Workshop, KVM Forum, Tizen Summit, Xen Project Developer Summit. As I’ve recently done with LinuxCon North America 2013 and ARM TechCon 2013, I’ll make a virtual schedule with selected developer sessions using the event’s schedule builder. You may find out several sessions will also be given in LinuxCon North America. Monday – 21st of October 11:00 – 11:50 – Bluetooth Smart Devices and Low Energy Support on Linux by João Paulo Rechi Vita, INdT This presentation will cover a brief introduction on how the Bluetooth Low Energy technology […]

$219 Kwikset Kevo Bluetooth Low Energy Dead Bolt

With RFDuino, BLEDuino, SensorTag, etc…, we know have several low cost Bluetooth Low Energy development boards / kits, however there are just a few Bluetooth SMART peripherals available right now, although many are currently being developed. One application of BLE will be the ability to use your phone to interact with objects around you, and Kwikset has just done that with its Kevo BLE Deadbolt that can be pre-ordered for $219 on Amazon with delivery scheduled by the end of October 2013. All you need to do is to load Kevo mobile app unto your iOS or Android smartphone to turn it into an electronic key (eKey), and unlock the deadbolt by simply touching it with your finger without having to remove the phone from your pocket or purse.  That looks highly practical, but at the same time very unsafe, so let’s have a look at some others features of […]

Texas Instruments Releases Android App for SensorTag and Publishes Bluetooth Low Energy Training Videos

Texas Instruments Sensortag is a Bluetooth Low Energy (BLE) development kit with 6 sensors (IR temperature, humidity, pressure, accelerometer, gyroscope, magnetometer) mainly destined at mobile application, which I recently tried in Linux. Until now, only it was only officially supported in iOS and Windows, but a few days after the release of Android 4.3 which adds Bluetooth Low Energy support, Texas Instruments quickly worked to release an Android App for their BLE devkit. The annoying part is that the Android app is only available as a Windows executable (SensorTagAndroidApp-0_9_0-windows-installer_2.exe), so you’ll have not choice but to use Windows to uncompress the files. Yet the installation goes as follows: Copy the SensorTag.apk file (SensorTag_0_9_0.apk) to your Android 4.3 device Enable installation of apps from unknown sources (Settings -> Security -> Device Administration -> Unknown Sources) Open file manager and launch, locate the .apk file and install the app by clicking the […]
