Fitbit moves to deal with diabetes

from Fitbit moves to deal with diabetes
by John Weir

Wearable fitness pioneer Fitbit is making moves in the growing market for diabetes management.

Having recently invested $6 million in Sano, a company that makes a coin-size glucose monitor, it has also announced a partnership with Dexcom to let users track their glucose levels (via the Dexcom G5 sensor) on the Fitbit Ionic smartwatch.

It’s new initiative is with American healthcare insurer UnitedHealthcare on a type 2 diabetes management pilot program. Participants will be given either a Fitbit Charge 2 or Ionic, which they’ll use along with a Dexcom monitor, to see how their activity levels are impacting their glucose levels.

This constant monitoring might be able to help patients determine what behaviours positively or negatively affect their glucose levels, and take action accordingly. And thanks to the personalized coaching and activity monitoring provided by the Fitbit device, users should be able to turn insights into action.

Recent EC2 Goodies – Launch Templates and Spread Placement

We launched some important new EC2 instance types and features at AWS re:Invent. I’ve already told you about the M5, H1, T2 Unlimited and Bare Metal instances, and about Spot features such as Hibernation and the New Pricing Model. Randall told you about the Amazon Time Sync Service. Today I would like to tell you about two of the features that we launched: Spread placement groups and Launch Templates. Both features are available in the EC2 Console and from the EC2 APIs, and can be used in all of the AWS Regions in the “aws” partition:

Launch Templates
You can use launch templates to store the instance, network, security, storage, and advanced parameters that you use to launch EC2 instances, and can also include any desired tags. Each template can include any desired subset of the full collection of parameters. You can, for example, define common configuration parameters such as tags or network configurations in a template, and allow the other parameters to be specified as part of the actual launch.

Templates give you the power to set up a consistent launch environment that spans instances launched in On-Demand and Spot form, as well as through EC2 Auto Scaling and as part of a Spot Fleet. You can use them to implement organization-wide standards and to enforce best practices, and you can give your IAM users the ability to launch instances via templates while withholding the ability to do so via the underlying APIs.

Templates are versioned and you can use any desired version when you launch an instance. You can create templates from scratch, base them on the previous version, or copy the parameters from a running instance.

Here’s how you create a launch template in the Console:

Here’s how to include network interfaces, storage volumes, tags, and security groups:

And here’s how to specify advanced and specialized parameters:

You don’t have to specify values for all of these parameters in your templates; enter the values that are common to multiple instances or launches and specify the rest at launch time.

When you click Create launch template, the template is created and can be used to launch On-Demand instances, create Auto Scaling Groups, and create Spot Fleets:

The Launch Instance button now gives you the option to launch from a template:

Simply choose the template and the version, and finalize all of the launch parameters:

You can also manage your templates and template versions from the Console:

To learn more about this feature, read Launching an Instance from a Launch Template.

Spread Placement Groups
Spread placement groups indicate that you do not want the instances in the group to share the same underlying hardware. Applications that rely on a small number of critical instances can launch them in a spread placement group to reduce the odds that one hardware failure will impact more than one instance. Here are a couple of things to keep in mind when you use spread placement groups:

  • Availability Zones – A single spread placement group can span multiple Availability Zones. You can have a maximum of seven running instances per Availability Zone per group.
  • Unique Hardware – Launch requests can fail if there is insufficient unique hardware available. The situation changes over time as overall usage changes and as we add additional hardware; you can retry failed requests at a later time.
  • Instance Types – You can launch a wide variety of M4, M5, C3, R3, R4, X1, X1e, D2, H1, I2, I3, HS1, F1, G2, G3, P2, and P3 instances types in spread placement groups.
  • Reserved Instances – Instances launched into a spread placement group can make use of reserved capacity. However, you cannot currently reserve capacity for a placement group and could receive an ICE (Insufficient Capacity Error) even if you have some RI’s available.
  • Applicability – You cannot use spread placement groups in conjunction with Dedicated Instances or Dedicated Hosts.

You can create and use spread placement groups from the AWS Management Console, the AWS Command Line Interface (CLI), the AWS Tools for Windows PowerShell, and the AWS SDKs. The console has a new feature that will help you to learn how to use the command line:

You can specify an existing placement group or create a new one when you launch an EC2 instance:

NEW PRODUCT – Adafruit SGP30 Air Quality Sensor Breakout VOC and eCO2

NEW PRODUCT – Adafruit SGP30 Air Quality Sensor Breakout VOC and eCO2


Breathe easy with the SGP30 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals.

This is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C.

The SGP30 has a ‘standard’ hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calculates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching.

3709 quarter ORIG 2018 01

This part will measure eCO2 (equivalent calculated carbon-dioxide) concentration within a range of 0 to 60,000 parts per million (ppm), and TVOC (Total Volatile Organic Compound) concentration within a range of 0 to 60,000 parts per billion (ppb).

Please note, this sensor, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a ‘true’ CO2 sensor for laboratory use.

Another nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC/eCO2 values.

For your convenience we’ve pick-and-placed the sensor on a PCB with a 1.8V regulator and some level shifting so it can be easily used with your favorite 3.3V or 5V microcontroller.
