Faster detection of hidden objects by Warwick Terahertz Sensor

Scientists at the University of Warwick have developed a new type of sensor that is much faster than competing technologies, used to detect and identify hidden objects. Called Q-Eye, the invention senses radiation across the spectrum between microwaves and infra-red, known as the Terahertz (THz) region of the spectrum ­- a goal that has challenged scientists for over 30 years. It works by detecting the rise in temperature produced when electromagnetic radiation emitted by an object is absorbed by the Q-Eye sensor, even down to the level of very small packets of quantum energy (a single photon). The device could help address the weaknesses reported earlier this month in America’s airport security, where mock weapons and explosives were smuggled through airports, undetected in 95% of cases. The Terahertz Sensor may also prove useful in discovering concealed goods in the retail industry or for non-destructive monitoring, for example quality control in drugs or food. Other applications include astronomical and climate science observations and medical diagnosis. Professors in Warwick’s Nano-Silicon Group, Physics Department, Evan Parker and Terry Whall, pictured above, led the team that developed the device. Professor Parker commented, “We were very surprised when our first very crude prototype showed such impressive speed and detection performance and our initial calculations indicated world-beating detector capability ­- all this and using silicon.” Made using standard silicon processes, large numbers of detector chips containing designs matched to a particular application can easily be fabricated on large (300mm) wafers with great uniformity, setting it apart from existing technologies. The patented device involves a thin film of aluminium deposited on top of a silicon layer placed under strain, used to create an electronic cooling (e-cooling) process. The electrons in the silicon layer are so isolated from the silicon lattice they become highly sensitive to incoming radiation. This revolutionary e-cooling process is the secret to the Q-Eye sensor’s exceptional performance, enabling fast imaging and material identification. Professors Parker and Whall are currently working on a demonstrator of the device, having been awarded a £100,000 Smart award from Innovate UK. The work is moving out of academic research into the commercial world, offering opportunities for partnership and investment. Companies involved in the personnel screening market have already expressed interest in the Q-Eye device. Warwick Ventures, Warwick’s technology transfer business, has helped the professors to create a spin-out company, Q-Eye Ltd, to develop and market the technology. Melody Stokes, Warwick Ventures Business Development Manager, and Phil O’Donovan, Warwick alumnus and a Cambridge based business angel, are working with the academics to build the commercial team, secure commercial partners and raise funding to develop the first commercial prototypes. Melody Stokes adds: “We’re delighted to have distinguished Warwick alumnus Phil O’Donovan advise the team. He brings invaluable experience of developing early-stage technology into scalable businesses. The global market for devices that operate in the THz region is growing at around 26% year on year, so Q-Eye is well placed to support the UK’s strategic lead in the sector. A longer term opportunity lies in quantum computing, set to revolutionise the way we handle and encrypt data.”

Axis Security Awards Recognising Exemplary Employees

Axis Security celebrated the successful achievements and extraordinary efforts of its employees during its seventh annual in-house awards ceremony at the Honourable Artillery Company in London. The event presented three awards: Security Employee of the Year, National Team of the Year, and London Team of the Year. The three awards given out to employees demonstrates the very best of Axis Security, recognising a strong work ethic, clear customer service skills, and a thorough commitment to all aspects of the job. Security Employee of the Year went to Neil Wilcox, Security Manager at Ark Data Centres, for his ‘above and beyond commitment’. Starting work as a security officer in 2010, early potential earned Neil a promotion to the role of supervisor, and again to his current position as security manager. He now manages a 22-strong team of officers at Ark Data Centres, in Farnborough, where his excellent customer service and supportive managerial style, including the training of new officers, is recognised as first-class. The Crown Estates, St James’s security team, scooped the London Security Team of the Year; and Dean Kelly, security supervisor, collected the National Security Team of the Year award on behalf of colleagues working at Wulfrun Shopping Centre, Wolverhampton. Chris Wisely, Managing Director for Axis Security, says that the consistent hard work of Axis employees is a hallmark of the service they provide: “We are genuinely proud of the commitment of our teams and individuals who are a credit to themselves, our customers, and our business.” http://www.axis-security.co.uk

Locken Launches Intelligent Vault Technology for Safe Key Storage

LOCKEN has announced the addition of the CyberKey® Vault 20S to its innovative solution. Based on Cyberlock technology, the Vault 20S brings additional value to LOCKEN’s solution in environments where it is more appropriate or advantageous to keep the keys in a centralised location. The vault prevents keys from ever leaving the premises, and with an integrated on-board computer it is designed to secure up to 20 rechargeable digital keys at any one time. The keys retained in the Vault 20S remain un-programmed until an authorised user presents an approved PIN or RFID device to the vault:  the vault’s internal server will then programme a key with the specified permissions. Once the user has returned the key to the cabinet, it charges the key’s battery and downloads the audit trail from its memory. Nick Dooley, Managing Director of LOCKEN UK explains: “This new multi-functional device meets the needs of many of our existing and potential single- and multi-site customers. It allows business managers to issue, programme and protect their smart keys simultaneously and to assign access rights in real time. “This new and advanced solution will result in improved smart key management, heightened security and increased efficiency.” For further information about LOCKEN, visit www.locken.co.uk, find us on Facebook or telephone 0203 691 1610.
