Back from the dead

Mobile phones and particularly smartphones are embedded within our lives. They managed our calendars, tell us where to go when we are lost, access social media sites, listen to music, and what the latest with the news and weather is. They can also make phone calls as well. So it is no wonder that people feel lost and out the loop if they have to have to go more than just a few hours without their mobiles. However, with their continuous use they obviously are subject to damage from outside elements and the environment. One of the most common forms of damage comes from water. Whether it is dropping your phone in a puddle, accidently leaving it in a pocket when putting trousers in a washer, using it in particularly heavy rain, leaving it in your pocket when you go for a swim or dropping it in the toilet (this happens far more frequently than you might think), then it can be goodnight for your phone followed by an overwhelming feeling of just how much of your life was contained in (and is now lost from) that tiny little black box. The Challenge The challenge this month is therefore to come up with a way of drying out a mobile phone or other similar electronic devices once they have been saturated within water. Many people have tried using a packet of rice to soak out the water inside the devices, while others have turned to using a hair dryer. The problem is the solution should not serve to cause any more damage than is already present. Crushed rice present in most packets is quite fine and dust-like and could find its way in to the phone's inner workings and congeal with water to make an even bigger mess. Similarly, using a hair dryer can cause as many problems as the direct heat could actually do more harm to the circuit board than good. Silica Gel is not a bad idea, but needs a bit of further thought to make it really effective. Ideally, the solution will act like a magnet to water attracting all water, moisture and water vapour from deep inside the embedded electronics. Furthermore, it would be beneficial if users could see how much water is still inside so they can gauge how long until recovery is possible. The solution we have in mind is a product that has recently been released. It has devised an intelligent solution to dry mobile phones and other electronic devices that have suffered from water damage. The solution is quite simple and rather elegant. When you see it you may consider it obvious. In the meantime, see if you can come up with a solution. -Solution- Solution to September 2012 Coffee Time Challenge The solution to the September 2012 Coffee Time Challenge to come up with a way to remove water that has soaked in to electronic devices that have been dropped or somehow immersed in to water comes from Lancashire based Rescuetec. Its resealable multilayer aluminium foil pouch provides a complete barrier to moisture. Inside is the Rescuetec recovery sachet containing a specially formulated compound which is like a magnet to water. The sachet is an exclusive Rescuetec product and allows both moisture and water vapour to pass through easily into the compound, whilst retaining the material securely inside. The Rescuetec compound will aggressively pull in water and water vapour from whatever contents are sealed into the foil pouch. The pack also contains an indicator strip, which shows how much moisture is still present and measures the extraction from 40% relative humidity down towards zero. In laboratory tests, devices cannot be properly recovered until the levels are well below 10%. The Rescuetec product is highly effective at these lower levels, thereby ensuring it removes as much of the moisture as possible before attempting to restart the device. The compound used in the Rescuetec sachet is up to 700% more effective than rice and up to 300% more effective than silica gel at these low levels. www.rescuetec.com
