The Future for Smartguns

Smart phones are a way of life, but have you heard about smartguns? Here in the USA a debate is raging about the introduction of this type of technology, while in Germany it has already passed into law. But firstly, what is a smartgun and what type of technology does it involve?

The idea is that only the rightful owner of the weapon can fire it. There are different mechanisms on the market for ensuring this and I would like to introduce a few here.

Trigger Smart is an Irish company. They have a system that uses radio waves. The weapon has a receiver placed in the handle and the owner is given a tiny HF transponder (something similar to the device found in your car keys) that can be worn in a ring or a bracelet. The gun will only fire when the correct ID number is received from the ring or bracelet.

The manufacturers argue that this makes the gun safer, as it cannot be fired by the kids while you are out or by an intruder or attacker that takes the gun off you in a fight. In the event of a shooting the police can also jam the frequencies and make the gun useless. In some cases a chip can even be placed under the owner’s skin.

Way back in 1975 a magnetic version of the same idea was invented, and is generally believed to work very reliably, although it is not widely used. Another system uses biometrics, identifying the owner through their grip and characteristics of their hands, but even the developers argue that the system is only 90% effective.

One problem with biometrics is that the gun needs time to process all of this input, but a US Austrian company called Biomac have a system that uses optical sensors to measure data from below the skin. They hope to design a system that will be accurate and work within half a second of picking up the gun.

Possible smartgun biometrics?

The gun lobby argue however that these security systems make the gun potentially more dangerous as any intruder may be able to block the radio systems, the batteries or other electronic parts may fail, parents who like to shoot with their children would have to buy them a dedicated weapon, and what if the owner is not in the house and another family member needs to defend themselves using the gun?

Even pro gun control groups are not convinced as it might even make gun ownership seem safer, leading to more sales, so it are very difficult to find in the USA.

The extent to which the gun lobby influences politics here is difficult to appreciate from outside the country. There is an attempt at the moment to make it illegal to buy a gun for someone who has been declined permission to own one. At the moment if I buy a beer for someone under 21 or give watered down wine to my son (as we did in Italy) I risk going to prison, but if I buy a gun for my friend who has been declined a license on psychological grounds I do not. There is no guarantee that it will pass though, as any form of gun control is fought tooth and nail and with the advantage of high financial backing.

It is not a completely dark picture though. The state of New Jersey actually passed a law to say that smartgun technology must be fitted to new weapons as soon as it has been developed enough and shown to be reliable. In Germany a law was passed in 2009 that goes even further, in that the technology will have to be fitted to all weapons old and new once it is available and proven. Unfortunately proven etc might take many years.

What none of the above really does is to address one of the biggest problems of gun ownership here in the USA, suicide. There is a massive increase in suicide rates in states where gun ownership is high. Suicide rates using other means remain constant, but a gun is a no return tool. Extremely efficient and easy to manage, success is almost guaranteed, and none of the technology that is currently under development can address this problem.

This Harvard University link explains the relationship, but it is enough to say that suicide rates are double in states where gun ownership is high, although non firearm suicide rates are about the same. To give an idea there were almost 20 000 firearm suicides in 2009 out of 36 000 total deaths, while there were only 11 000 murders.

The debate will rage for many years to come, but what part will smartgun technology play?

Top 10 Emerging Technologies

A couple of weeks ago the World Economic Forum published a document on its blog called “The top 10 emerging technologies for 2013”. I thought it might be interesting to have a look at what they say. The article can be read here. The comments are my own interpretation however.

World Economic Forum

1. Online Electric Vehicles.

About 100 years ago a scientist called Tesla demonstrated that electricity could be provided wirelessly. Today there is an idea that electric cars could drive while being recharged from electromagnetic fields created from cables under the road. The cars would need much smaller batteries of course.

The problem with this technology seems to be that it is difficult to measure how much power is taken, so difficult to bill for, nothing more than that. Take a look at this article about other ways of cutting pollution from transport systems.

2. 3D printing and remote manufacturing.

Much has been written and the technology undoubtedly carries advantages, but did you read my post about 3D printers potentially being used to make gun parts?

3. Self Healing Materials.

A great idea but this and other uses of nanotechnology and its production practices need to be regulated, as does the disposal of such materials. We don’t know enough about the effects upon human health as the recent report cited in another post on this blog demonstrates.

4. Energy Efficient Water Purification.

Must be a good thing. Some of Christopher’s thoughts on the issue here.

5. Carbon Dioxide conversion and use.

Geo-engineering offers the possibility of drawing carbon dioxide from the air and storing it underground, but this technology is extremely controversial. This article entitled Engineering a Solution to Global Warming gives an idea of some of the ethical debate surrounding such processes.

6. Enhanced nutrition to drive health.

Genetic modification of plants to make them more nutritional. Much has been written about the GM issue, it is certainly not as simple as it may sound. Great commercial interests are involved, as are problems of cross fertilization and non-reproducibility. See this article on the Bassetti Foundation website about the Vatican and its interests in the problem.

7. Remote sensing.

The buzz-phrase Smart City is all over nowadays. Have a look at this article for some ideas of how using sensors might improve urban life.

8. Precise drug delivery through nanoscale engineering.

Medicine is the area in which nanotechnology research shows its greatest potential. The problems of regulation still exist as brought up in the article above, but the possible advantages for society make this type of research extremely valuable.

9. Organic electronics and photovoltaics.

This article mentions solar panels made using fruit and vegetable juice instead of silicon, and the printing of circuits using organic materials is already a reality. Silicon is more efficient at the moment, but expensive, polluting and will eventually run out, but if scale is not a problem these solutions work well.

10. Fourth generation nuclear reactors and waste recycling.

Making nuclear energy cleaner and better is the goal. The questions of safety and sustainability as well as real cost are not raised however, again not an argument that can be expanded upon too much as it is extremely polarized, but there are cleaner and safer ways to produce electricity as the article about electricity generation cited above shows.

Well it looks like we got most of it covered at Technology Bloggers anyway, cutting edge as we are.

Touchscreen Problems (Zombie Finger)

iPad zombie finger - Touchscreen ProblemsOver the last couple of weeks I have flown from the USA to Britain, then to Italy, and back finally to the USA. I flew on some lovely new Airbus aircraft, but had a constantly recurring problem with the on-board entertainment systems.

The problem is that in the seat above me there is a fantastic touchscreen entertainments system, but my fingers do not work. My son who was sitting next to me has good fingers, he touches the volume section and can turn the sound up or down, but I cannot because the slider does not seem to recognize my body.

So it must be my screen I think, my son leans over and it works perfectly well for him. We swap places, now mine works for him but I still cannot change the volume, this time on a different machine.

It must be me I conclude, but why? Long ago I gave up using anything touchy for this reason. I try licking my hands, warming them up, cleaning the screen but I do not make any progress. So I started looking around the web for some answers to find that I am not the only one, hurrah. There is even a recognized name for the problem in some fields, Zombie Finger!

Touch screens operate in many different ways. At Walker Mobile you can download a free PDF that explains how the different technologies work, but the vast majority of application that we know use one of two approaches. They can be described as Resistive Touch and Projective Capacitance.

Resistive touch is old school analogue. Two surfaces are together, typically one of glass with a thin film over it. You push down on the film and it makes a circuit using a grid of electrical conductors. The system is cheap but being mechanical liable to damage and wear, and it is thick.

Projective Capacitance has no moving parts however, and some of its advantages mean that it is rapidly taking over the market. It is a system that works on capacitance, which is the thing that gives you a shock when you walk over a synthetic carpet and then touch the brass door handle in the hotel that you are staying in.

iPhone touch screen technology

How iPhone touch screens work.

Again there are two layers, both charged but to a different extent. When you touch the screen some of the charge is released into your finger, and this tiny change can be measured. And here lies a variable, because the nail will not carry a charge, gloves stop the action and so I wonder if even the state of the skin at the end of the fingers might effect usability. Do I type too much? No charge transfer means no volume.

For a fuller explanation of these 2 competing systems see this article, it is short but extremely informative. I would just like to know if anyone else has issues with touch screens, and if so if they have been able to address the issue in some way. As technology advances this interface is becoming the norm, and we wouldn’t want to leave people with particular skin types behind now, would we?
