Re: don't agree
Yet, as people begin to turn smartphones into medical devices, there is that risk that many people will be harmed without standard. It is very difficult to work on meedical systems as not all humans are the same. I feel bad when I go to Google Play and see hundreds of EEG monutors that practical deceive people are their health conditions. We need tougher oversignt in the new sector.

Yes, there is much interest on putting medical applications inside smartphones and tablets,the main goal is  to have a remote access to the medical data. I think this interest will grow in the near future.

They eat the pride as Apple does not pay that well, unfortunately. Yet, Apple in your resume can land you a big gig somewhere after few years there. It is a hugely innovative firm that is destined to dominate the tech space for a long time with their infinite resources.

There are many ideas floating in the medical industry. These applications can go. I just read one by a billionaire that wants to put all medical dataset of all 7.2 billion people on earth. Those sets will be updated as people visit hospitals and get treated. Possibly with that, lessons can be learned on what works best.

There are many projects in that space across the globe. There is absolutely activity there from Silicon Valley to Boston. The real challenge is the quality of the measurements of these systems owing to varying natures of the human systems.

Re: don't agree
I can't recall the source now, but several ongoing projects I've read of (and talked with other collegues) are centered on developing a set of biomedical sensors with wireless communications capabilities for sensing body temperature, heart&breath rates, epylepsia attack preludes, intraocular pressure, CO2 concentration, and several other constants and parameters. Some captures are 'simply' for data-logging but a number of projects are focused on real-time patient monitoring, so the system can automatically fire alarms to remote health care, family members or even to the patient's mobile phone to instruct him/her of taking some mitigating actions.

Re: don't agree
It will be very interesting to see the differences between this model and the previous model of the galaxy series. For example I don't see a big differences between S4 and S3 models. I hope S5 will surprise me.

I do not think we need to see a lot of difference in these products when you consider that most are coming out within a window of 18 months. Instead of technical differentiation, the key factor to look for is cost. Can they deliver the next one at 50% of the cost of the previous one? It is only in phones do not see the Moore's law working.

Unless you are an utility, I do not think government needs to regulate pricing. Regulating pricing distorts market equilibrium and causes many problems. What government needs to do is to have a platform for healthy competition.

Re: don't agree
S5 smartphone is rumoured to have integrated sensors for safety applications. 

Any idea what these safety sensors are supposed to do? Medical in my smartphone? That seems scary I must point.

Previously we looked at the electronics and sensors involved in data acquisition systems (DASs). Now we look at what to do with the raw ADC data once it is acquired.
This is a tutorial presentation of principles of instrumentation that is typically multi-channel, medium to high resolution (12 to 20 bits) and relatively slow - slower than oscilloscopes in sample rate
Continuing the chat from last time, we turn now to a circuit-related topic, that of current waveforms. The typical converter input waveform is shown with a static (dc) component and a ripple (ac) component
Semiconductor companies have now had fully-differential amplifiers in their product lines for a few years, though these amplifiers have been in leading-edge electronics for decades. These diff-amps are differential not only at their input but also at their output, doubling output range.
