Things are changing fast in medicine, thanks to mobile.

by

Wow – this is an amazing video on just how much smartphones can help reduce costs, increase healthcare efficiency and improve patient well-being and outcomes.

We may not be fully there yet in terms of the widespread availability of this hardware and software, and then there’s getting it accepted by the medical establishment, but this is certainly a big step in the right direction.

A search in the iPhone App store for the term ‘Glucose” returns 217 apps and a similar number for the term ‘ECG’, while a search for ‘Glucose” in the Google Play Android apps store returns over 1,000 results

Things are changing fast in medicine thanks to mobile – exciting times ahead.

Public transportation, smartphones and economic development – a winning combination for Miami-Dade

by

It is hard to make public transport interesting, but Miami-Dade Transit in Florida is certainly giving it a go!

Their Metromover automated people mover is the most successful downtown people mover in the United States, and it is free!

Their Metrorail and some of their Metrobus services have on-board wifi (based on cellular service), and it is free.

They have smartphone Transit Tracker apps for iOS and Android devices allowing passengers to get realtime information on arrival times, station information and trip planning.

And they plan to make more improvements still. One of the ideas I particularly liked is outlined by Carmen Suarez, an Enterprise Architect with Miami-Dade Enterprise Technology Services Department at 01:30 in the video above.

The idea is to send push notifications to the smartphones of people who have the Transit Tracker app on their phone. The notifications would advise people of special offers/discounts from local businesses near their destination. It sounds simple enough, but as Carmen points out in the video it gives people yet another reason to use public transport, it helps reduce traffic congestion, and it promotes economic development in those areas. Win, win, win.

What cool public transport and smartphone-related stories have you come across?

IBM Pulse redux – Smarter, sustainable.

by

I attended IBM’s service management conference IBM Pulse last week and I came away very impressed with how IBM’s suite of Smarter solutions is nailing sustainability (even if that’s not how they see it!).

The main areas I was interested in were the Smarter Cities, Smarter Buildings, and Smarter Transportation. I also wanted to check out their data center infrastructure management (DCIM), but there’s only so much I could fit into the two days!

The Smarter Cities solutions coming out of IBM are compelling, to say the least (though undoubtedly, given the politics in public administration, a tough sale!). One of the better talks at the event was by Boston CIO, Bill Oates. Bill talked about, amongst other things, how Boston had rolled out a smartphone app for citizens to report when they saw a problem in the city (litter, pothole, graffiti, etc.).

When a report comes in from a smartphone, it is immediately placed in a word order, and a city employee is tasked with resolving it. The inclusion of photos and GPS coordinates in the report obviously help enormously in speeding up its resolution. When the issue is resolved, the person who reported is notified, and is told which city employee fixed it! This is a fantastic way of personalising the city government back to the people – social at its best. Boston are now adding some gamification features to the app as well to make it even more compelling.

When Bostonians were asked why they liked the app so much their response was that previously to report a problem, they had to ring the city hall, and that felt like they were complaining, whereas with the app they feel like they are part of the solution.


On the Smarter Buildings and Smarter Facilities front, it was great to see Tririga getting a lot of love at the event. We first wrote about Tririga here on GreenMonk back in 2009, and subsequently we wrote an email to several senior IBM execs introducing them to Tririga. It was nice to see them being acquired by IBM after that! Tririga is a suite of products designed to optimise use of a facilities portfolio. That can be done in any manner of diverse ways from identifying inefficient building stock in a portfolio of buildings, to simply spotting an open window in a building, and raising an alert.

Somewhat confusingly, as well as Tririga, IBM also has a Smarter Building Solutions group. This group works more on the buildings’ maintenance side of the house. This is vital for ensuring that buildings are running optimally at all times and minimising waste through downtime, or equipment failure.

In a similar vein, the IBM Smarter Transportation offerings from IBM make big use of what they call their Predictive Asset Optimisation (i.e. predictive maintenance). This is when the software analyses the (big) data coming from thousands (or even hundreds of thousands) of sensors looking for anomalies. These exceptions, once identified can often be caused by a part going out of tolerance and needing a repair, or replacement. Obviously, finding this out ahead of time allows for replacement parts to be ordered in advance, and maintenance to be scheduled when it suits, as opposed to reacting when the equipment fails. There’s obviously a big safety story here too. Avoiding catastrophic failures in transportation is in everyone’s interest.

IBM isn’t branding these solutions as being sustainable, per se, but from what I’ve seen at Pulse, there’s no doubt in my mind that Smarter ≡ Sustainable.

Full disclosure – IBM paid travel and accommodation for me to attend this event.

Smartphone energy management – at last there is an app for that!

by

Carat

The World Bank issued a report yesterday showing that the number of mobile phone subscriptions in use worldwide, both pre-paid and post-paid, has now reached over 6 billion.

The report went on to reveal that more than 30 billion mobile applications, or “apps,” were downloaded in 2011 alone – these apps extend the capabilities of phones, for instance to become mobile wallets, navigational aids or price comparison tools. However the apps also have a cost associated with their use – they drain the phone’s battery.

Carat - smartphone energy managament

Some of these apps are energy hogs – they require a lot of energy to run, and so they drain the phone’s battery quickly (maybe they are legitimately using the camera, the GPS radio, and the 3G network simultaneously). Other apps have bugs in them whereby they may not properly close out battery use after a particular function and they continue to drain the battery. Until now, there has been no way to identify which apps were the ones draining your battery’s charge.

I have written a couple of times here before wondering why there was no energy management app for smart phones. Now there is – Carat.

Carat has been developed by a very small team at the Algorithms, Machines, and People Laboratory (AMP Lab) in the Electrical Engineering and Computer Sciences (EECS) Department at UC Berkeley, in collaboration with the Department of Computer Science at the University of Helsinki.

The app is free and available for both the iOS and Android platforms. And the client-side code has been uploaded to Github, where anyone can download it, and if they have the development chops, potentially fix any issues they find, or even improve on the app.

As every Smartphone owner knows, battery life is a massive problem. Carat discovered just how big a problem when TechCrunch wrote a piece about the app a few weeks ago. Carat had estimated that they’d pick up an extra 10,000 users as a result of the article. Instead 250,000 people installed the app on their phones and Carat had to scramble to deal with the massive, influx of data.

As can be seen from the image above, Carat gives you advice on ways to get longer life from the battery in your smartphone by identifying Battery Hogs (apps that use a lot of energy), apps with energy bugs and advising on how much extra battery life you will save by re-starting or killing the app.

Carat also reports your J-Score:
Carat J-Score

The J-Score is “the percentile battery life you see relative to all other devices being measured by Carat”, so the J-Score of 54 reported for my phone means my expected battery life is better than 54% of Carat’s users.

One thing to be aware of is that because Carat needs a certain threshold of application usage before it can report accurately on your apps, it typically takes a weeks usage before it starts advising you on how to get better battery life for your device.

Speaking to Carat developer Adam Oliner last week he informed me that some of the next steps for the app will be to publish api’s so that app developers will have better access to the energy consumption info of their applications.

What is interesting about this app is that it was developed as a research project, and not by one of the Smartphone Endpoint Management providers. You’d have thought saving their customers money and reducing their emissions (through using less energy), while keeping their employees more productive (by prolonging the battery life of their smartphones) would have been a no-brainer.

Perhaps, now that it has been shown that this is possible, we’ll see more of these types of apps emerge.

Smartphone energy management – when will there be an app for that?

Mobile energy saving app?

I wrote a post last week about mobile endpoint management applications and their potential to extend smartphone battery life. It seems it was a prescient piece given the emergence this week of a study from Purdue University and Microsoft Research showing how energy is used by some smartphone applications [PDF].

The study indicates that many free, ad-supported applications expend most of their energy on serving the ads, as opposed to on the application itself. As an example, the core part of the free version of Angry Birds on Android uses only 18% of the total app energy. Most of the rest of the energy is used in gathering location, and handset details for upload to the ad server, downloading the ad, and the 3G tail.

This behaviour was similar in other free apps, such as Free Chess, NYTimes which were tested on Android and an energy bug found in Facebook causing the app to drain power even after termination, was confirmed fixed in the next version released (v1.3.1).

The researchers also performed this testing on Windows Mobile 6.5 but in the published paper, only the Android results are discussed.

Inmobi’s Terence Egan pushed back against some of the findings noting that

In one case, the researchers only looked at the first 33 seconds of usage when playing a chess game.

Naturally, at start up, an app will open communications to download an ad. Once the ad has been received, the app shouldn?t poll for another ad for some time.

Hver the time it take to play a game of chess (the computer usually beats me in 10 minutes) a few ad calls are dwarfed by the energy consumption of the screen, the speakers, and the haptic feedback.

Although, in a tacit admission that this is a potential issue further down in his post he lists handy best practices for developers to make “ad calls as battery friendly as possible”

The iPhone iOS operating system wasn’t looked at in this study at all but it is not immune from these issues either. And, in fact, reports are emerging now that the new iPad is unable to charge when certain energy intensive apps are running.

While it is important to remind developers of the need for green coding, not all coders will heed the advice and there will always be rogue apps out there draining your smartphone’s battery.

And this is not just a consumer issue – for enterprises it is important to keep the organisation’s smartphone owners happy, connected, and above all, productive. A drained battery is ultimately a disconnected, unproductive and frustrated employee. Reducing a phone’s energy use is, obviously a sustainability win too.

Mobile endpoint management applications could use technology similar to the eprof software used in the study, to identify bugs or rogue applications on phones. This could be reported back to a central database to alert users (and app developers) of issues found.

With more and more apps coming on the market, this is an issue which is only going to become more pronounced. Someone is going to come out with a decent mobile energy management app sooner, rather than later. It will be interesting to see where it comes from.
