Ricardo-AEA was formed on November 8, 2012, when Ricardo acquired the business, operating assets and employees engaged in the business of AEA Technology Plc , for a total cash consideration of £18.0 million.The acquisition saw the AEA Europe business, including an operational staff of approximately 400 located at five UK sites, transferring to Ricardo where it began to operate as Ricardo-AEA under the continued leadership of Robert Bell, reporting to Martin Fausset, managing director of Ricardo UK. Based on its most recent reported results, the assets acquired generated, for the year ended 31 March 2012, annual revenues of £39 million and delivered operating profit margins similar to those of the rest of the Ricardo group.AEA Technology plc was formed in 1996 as the privatised offshoot of the United Kingdom Atomic Energy Authority. It was a constituent of the FTSE Fledgling Index. Originally it consisted of divisions with expertise in a wide variety of areas, mostly the products of nuclear-related research. These included nuclear safety, nuclear engineering, environmental protection, battery technology and non-destructive testing. It mainly acted as a contractor organisation for UKAEA and other governmental and private customers.AEA Technology was an energy & environmental consultancy business. The company divested all of the nuclear-related elements of the business and other non-core businesses such as its Rail business through two portfolio sales to secondary private equity investment firms in September 2005 and in September 2006 respectively. In addition to environmental consultancy the company also works in the Knowledge Transfer and Programme Management areas. The business is organised around a mesh style "communities" structure which includes Knowledge Leadership , Project Management, IT, Marketing and Sales.The company's main UK operations are located at the Harwell Science and Innovation Campus in Oxfordshire , London, Risley and Glasgow . In August 2006, AEA established a Romania Subsidiary in Bucharest and this was shut down in April 2009.AEA Technology was voted best Consultancy for Climate Change and Renewables in the EDIE Awards 2007.Andrew McCree quit as Chief Executive Officer in November 2011 and was replaced by John Lowry as Interim CEO. Lowry has previously been involved in the UK's National Health Service as a restructuring advisor.AEA Technology made a number of redundancies throughout 2010; the then CEO, McCree, was quoted as saying " 10 per cent off the UK cost base in the year, involving 60 redundancies". AEA has also seen a continuing slump in its share price: from 277p in November 2003 to around 0.4p in January 2012. Shares lost up to one third of their value during 2010 and were even temporarily suspended on the stock exchange.AEA Technology was fined £250,000 for transporting a 2.5 tonne 60Co gamma radiation source from Cookridge Hospital, Leeds, UK, to Sellafield with defective shielding on 11 March 2002. The company is no longer involved in the transportation of nuclear material. Wikipedia.

An engine-driven vehicle includes an energy recovery system (

Systems and methods for continually determining the remaining useful life of a drivetrain. The remaining useful life is continually determined during real-time operation of the drivetrain by determining a duty cycle based on torque and rotary speed measurements of the drivetrain. The duty cycle is converted into a useful life reduction, which is subtracted from the then-existing remaining useful life of the drivetrain. The systems and methods can additionally include displaying a remaining useful life during operation of the drivetrain, and generating an alert when the remaining useful life approaches or reaches zero. The drivetrain is optionally associated with an internal combustion engine, a wind turbine, or a gas turbine.

An apparatus and method are provided for constructing a magnetic gear coupling for transmitting torque from a flywheel to a driveshaft, the coupling employing permanent magnet arrays and magnetic flux coupling elements therebetween, and at least one of the arrays and coupling elements being circumferentially staggered or spread, so as to avoid complete alignment of the arrays and elements, and thereby mitigate torque coupling capability variations.

A front drivetrain capable of providing all-wheel drive to a rear-wheel drive architecture. The front drivetrain is coupled to the front end of the crank shaft and includes a power-split planetary gear arrangement that couples an electric machine to the front drivetrain. In one embodiment, the planetary gear arrangement includes a sun gear coupled to the crank shaft, a planetary gear set with a carrier coupled to the driveshaft, a ring gear coupled to the electric machine. The driveshaft may be connected to left and right front axles by a bevel gear set and a differential. In an alternative embodiment, sun gear may be coupled to the electric machine and the ring gear can be coupled to the crank shaft. In this alternative embodiment, the planetary gear set remain coupled to the driveshaft.
