Faraday bags help secure seized mobile devices
Law enforcement and counter terrorism agencies now have a solution to the problems of what to do with mobile phones and other connected devices that are seized from criminal suspects.
At present, devices and data held on them that are seized can provide valuable intelligence and evidence if they are left switched on, but officers run a number of risks in not turning off the devices. A device that is left switched on can potentially be remotely wiped, or any communications that are received after the device has been seized may not be lawfully accessed, and in certain cases, active mobile phones could even be used to remotely trigger explosive devices.
Now UK company Disklabs is offering a solution to the conflict between the need to isolate the device while still having access to the data on it, with the launch of its Phone Shield Faraday bag line up.
The range consists of small, lightweight bags constructed of silver, nickel and copper, which create a Faraday shield, an enclosure of conductive material which blocks external non-static electric fields such as mobile phone signals.
A transparent window in the bag allows officers to continue to access the device, so that they are still able to actively carry out investigations on site, without having to remove the device to a fixed Faraday cage.
The bags are available in mobile phone, laptop and holdall sizes, and the company also manufactures cable shields, which allow the device to plugged in to a charger to keep it powered, without the risk of the cable acting as an antennae. The solutions are capable of blocking all major frequencies, including: 900Mhz, 1800Mhz, 1900Mhz, 2.1Ghz, Bluetooth and Wi-Fi.
Harlan Simpson, director of Disklabs commented: "We are getting more and more orders from organisations that simply were not aware that these signal blocking products were available. We are now receiving orders from several Counter Terrorism Units around the world.

Faraday's later discoveries in the field of electromagnetism were to be the basis for the creation of technology powered by electricity, but much of what he achieved had some basis in what he had learned from his mentor. Davy is perhaps best remembered
Though lightning bolts capable of seizing humans give them the upper hand in open combat, earthlings can protect themselves, their homes and even their pets with makeshift Faraday cages (look it up or ask a science-inclined friend).
This electromagnetic induction was first discovered way back in 1831, by a physicist named Michael Faraday. He discovered it when he had two different coils and introduced power into just one of the coils. He was astounded to discover that the magnetic
Wesley also has a collection of Edison Lamps that are powered by batteries. These were used in Faraday and other local mine sites with the charge lasting for a full shift. Wrapping up on Sunday afternoon, the Gemboree staff and volunteers will have
Coating keeps fuel cells vital | FuelCellsWorks
In large amounts, the otherwise useful element chromium is considered toxic and carcinogenic for humans. It’s also poisonous to solid-oxide fuel cells (SOFCs), evaporating from ferritic stainless steel-based interconnects and increasing the electrical resistance. This reduces efficiency and operational lifetime, and is the primary challenge facing developers of SOFCs as viable power sources. SOFCs are considered an attractive power producer of electricity because their only reaction products are water, carbon dioxide, and electricity.
A team of experts from the National Energy Technology Laboratory , Albany, Ore., West Virginia University , Morgantown, W.V., and Faraday Technology Inc. , Clayton, Ohio, have developed a manganese-cobalt (Mn-Co) spinel coating specifically tailored for interconnects that prevent chromium poisoning of the cathode, extending the life of the stack. This Electroplated Mn-Co Coating for Solid Oxide Fuel Cell Interconnects works by limiting the transport abilities of chromium and oxygen while also meeting a number of criteria necessary to prevent the coating itself from interfering with the action of the SOFC. It is thermodynamically stable, has low ohmic resistance, has a well-matched thermal expansion coefficient, and is chemically compatible with the remainder of the stack.
