Inertial MEMS accelerometers That are 1000 Times more Sensitive will benefit applications such as bridge, infrastructure and seismic monitoring
A MEMS accelerometer is a sensor that can be used to measure vibration, shock or change in velocity. By deploying many of these detectors as part of a complete sensor network, HP will enable real-time data collection, management evaluation and analysis. This information empowers people to make better, faster decisions, and take subsequent action to improve safety, security and sustainability for a range of applications, such as bridge and infrastructure health monitoring, geophysical mapping, mine exploration and earthquake monitoring.
The HP sensing technology enables a new class of ultrasensitive, low-power MEMS accelerometers. Up to 1,000 times more sensitive than high-volume, commercial products, sensors based on this technology can achieve noise density performance in the sub 100 nano-g per square root Hz range to enable dramatic improvements in data quality. The MEMS device can be customized with single or multiple axes per chip to meet individual system requirements.
The sensing technology is a key enabler of HP’s vision for a new information ecosystem, the Central Nervous System for the Earth (CeNSE). Integrating the devices within a complete system that encompasses numerous sensor types, networks, storage, computation and software solutions enables a new level of awareness, revolutionizing communication between objects and people.
“With a trillion sensors embedded in the environment – all connected by computing systems, software and services – it will be possible to hear the heartbeat of the Earth, impacting human interaction with the globe as profoundly as the Internet has revolutionized communication,” said Peter Hartwell, senior researcher, HP Labs.
Legislative update – Sept. 2009 — REACH, RoHS2
Summary
The legal obligations within the REACH Regulations and the potential impact of the so called “RoHS2” proposals dominate the legislative scene at present. Also, obligations are starting to filter through as part of the eco design/energy using Products Directive that monitors energy efficiency throughout a products life cycle. Going-forward, the scope of this directive will become more diverse to encompass energy related products.
Industry, and the design engineer, needs to be aware of developments and the potential impact on their companies.
REACH
Regulation 1907/2006, the Regulation, Evaluation, Authorisation -and restriction-of Chemicals (REACH) entered into force on 1 June 2007 after almost 8 years of debate and covering some 849 pages of regulation.
The only census on chemicals, taken in 1981, highlighted that 100,106 substances were placed on the market. Of those used, manufactured or imported at levels of 1000 tonnes or more, 21 percent had no safety data at all while a further 65 percent provided insufficient safe use data. Only 3 percent had been fully tested.
At the same time, instances of allergies, asthma, certain types of cancer and reproductive disorders were on the increase in Europe. Skin diseases alone resulted in the loss of 3 million working days per year.
Driven by the obligatory flow of safety data throughout the supply chain, REACH seeks to provide protection to health and the environment.
The biggest challenge to industry to date has been around the collection of data advising where a so called Substance of Very High Concern (SVHC) is present in a product, known as an article in the regulations, at a level of 0.1% by weight of the total article.
As a minimum obligation the name of the substance along with supporting safe use data must flow downstream through the supply chain.
Substances that are categorised as SVHC include those that are carcinogenic, mutagenic or toxic for reproduction. Also, substances that are persistent, liable to bio-accumulate and toxic, and finally “others” such as endocrine disrupters that can have a particular impact on aquatic life.
Back in October 2008, the first batch of 15 substances of very high concern was published by the European Chemicals Agency and, the following January, seven of these were earmarked for a consultation on whether or not they should be subject to a very costly “authorisation of use” requirement. These seven were approved and the European Commission will determine the date when these will be added to Annex XIV.
These obligations will then enter into force some 42-48 months later on what is known as the sunset date. Where such an authorisation is approved, downstream users can only use these substances for the use that they have been authorised for and they can only be purchased from the company granted the authorisation.
The REACH data collection has resulted in the circulation of hundreds of “standard letters” in a multitude of formats. Many manufacturers have refused to reply to the ad-hoc requests they receive preferring to promote websites or central databases (these have been slow to develop).
Guidance on the regulation encourages a more pro-active approach rather than simply providing a link to a website. Likewise, there have been many random requests for information that is not obligatory such as pre-registration details and RoHS style certificates of compliance.
Future batches of SVHCs will be published on an on-going basis, with the next expected early 2010, so REACH will not be a box that can be ticked as complete for several years to come.
“RoHS2”
Looking back the Restriction of Hazardous Substances (RoHS) Directive 2002/95 entered into force on 1 July 2006. It featured six restricted substances across eight broad categories of product pulled from the 10 categories in the Waste Electrical and Electronic Equipment (WEEE) Directive. There were 29 exemptions to assist manufacturers and design engineers where no viable alternative was available and a whole raft of “grey” definitions that required clarity.
“RoHS2” proposals look to move the directive forward and provide greater clarity. However, some of its provisions will potentially have cost and resource issues for industry.
The proposals recommend that the two remaining categories from the original WEEE categories, namely medical devices and monitoring and control instruments be added to the scope from 2014 (in-vitro diagnostics from 2016 and industrial “test” equipment in 2017). These were originally omitted from the directive due to reliability concerns over the use of lead-free solder.
While there are no substances actually restricted under the proposals, four are recommended for priority assessment. Three plasticisers used in a variety of applications and a flame retardant may well be restricted. Ironically, the substances, BBP, DBP, DEHP and HBCDD are four of the seven subject to authorisation of use under the REACH Regulations.
The fate of these substances under RoHS will be open to consultation after the revised directive comes into scope sometime in 2011-2012. Either way, any restriction under RoHS will probably be sooner than under the REACH process and the analysis is unlikely to be done twice.
Under a separate review by European Commission consultants, 29 exemptions will continue under the proposals, many with amended wording for clarity, 6 will be withdrawn and one new one will be granted. These could come into force next year and that will be followed by a transposition period of, on average, 18 months allowing manufacturers the time to comply.
In addition, a further six exemptions were added in June 2009 that had been proposed a year earlier.
RoHS2 also clarifies definitions such as equipment within out of scope equipment, spare parts and military where the latter clearly does not include dual use equipment.
A standard, and rigid declaration of conformity appears in annex 7 and will replace the multitude of different certificates, statements and compliance documents under the original legislation.
There now appears to be no scope for qualifying statements such as “so far as we are aware” and “to the best of our knowledge”.
It is proposed that RoHS will become a CE mark directive placing responsibilities on manufacturers, importers and distributors. There are many requirements including building technical files and keeping for 10 years, ensuring products comply, that they are supplied with the CE mark and the manufacturer or importer is identified on the product. Sample testing should also be carried out where appropriate, and corrective action is undertaken where product is found to be non compliant.
Finally under the proposals, the broad product categories and list of indicative products move from the WEEE Directive and sit in annex 1 and 2 of the RoHS Directive.
The terminology “RoHS2” is unofficial and is used simply to highlight the proposed changes to the original directive.
Energy using Products
Directive 2005/32/EC, Energy using Products, entered into force on 11 August 2007.
The main aim is to monitor energy efficiency throughout the life cycle of a product from the mining of raw material right through to recycling at end-of-life.
The focus is clearly on the design phase of the product since it is considered that this is the determining stage affecting the resources used in a product.
The directive does not apply to means of transport (planes, cars etc) but, apart from this, the scope is deliberately broad covering, in principle, any product which when in use depends on, generates, transfers or measures energy (electricity, fossil fuel or renewable).
Obligations on manufacturers will result from a series of specific “implementing measures” the first of which was adopted in January 2009.
The criteria required before a product can be considered for assessment is that is that it must sell more than 200,000 units per year in the European Union, have a significant environmental impact and present considerable potential for improvement. The latter is important as the target is for a 20% improvement in energy efficiency by 2020.
During phase one, studies were commission on 20 broad product categories ranging from water heaters, televisions and lighting, through to imaging equipment and personal computers.
Beyond that, a further 17 categories have been highlighted from ovens and hobs, machine tools and air-conditioning equipment through to transformers and networking equipment.
Among the first obligations to come in to force were energy efficiency improvements covering standby and off-mode losses, simple converter boxes for digital television, external power supplies and office, street and domestic lighting.
However, the European Parliament has now adopted the European Commission’s (EC) proposal to widen the scope of the directive to include energy related products. Until now the Energy using Products Directive was limited to products that consume energy during use such as boilers, computers, televisions, industrial fans and light bulbs.
However, many products have an indirect impact on the energy in use such as water using devices, taps and showerheads for example, and double glazing windows or insulating material.
Improvement in design could clearly result in the significant saving of energy.
For example, water saving taps and shower heads reduce water consumption and therefore the amount of energy used for hot water.
Under the EuP Directive studies had to set requirements for individual products where, in fact, it is the performance of the whole system that often needs to be optimised not just a single component or products.
The new directive will repeal the existing 2005/32/EC.
Intel and Sun Micro Product Roadmap Updates
* Intel will show off “Westmere,” the first processors built using a 32 nanometer (nm) manufacturing process.
* CPU manufacturing shrank from 65nm to 45nm to 32nm and next to 22nm.
* The next chip architecture will come in 2010, in the form of the new architecture codenamed “Sandy Bridge,” which will also be disclosed at this month’s IDF. Intel’s roadmap is process shrinkage and then better architecture and then process shrink etc… (tick-tock)
* This new-generation high-k metal gate transistor formula will give Intel “a 3+ year advantage in addressing leaky and energy inefficient transistors,” according to a blog post from Intel spokesman Bill Kircos Intel has shipped >200 million 45nm CPUs using high-k+ metal gate transistors.
* For the first time, Intel has developed a full-featured SoC process technology to complement the CPU-specific technology. This version is for our smarter System on Chip (SoC) product efforts, which emphasize lower power transistors
* Intel NMOS transistors now have 19% performance improvement over their 45nm counterparts and our PMOS transistors now have a 28% performance improvement over their 45nm counterparts.
* Another IDF highlight: Nehalem-based chips codenamed “Jasper Forest” and designed for the embedded and storage sectors. This family of products will bring Nehalem to the embedded market, offering integrated PCI Express (PCIe) and an integrated I/O hub in a dual-processor Xeon processor.
* Nehalem will allow for much faster and denser storage and communications solutions such as IPTV, VoIP, NAS, SAN and wireless radio network controllers
The UK Register has information on the Sun Sparc Roadmap. The 16-core “Rock” UltraSparc-RK processor for Sun’s once-and-never “Supernova” line of servers is not on the roadmap. The one-page roadmap is one given Sun’s customers – and presumably also Fujitsu’s customers – have been shown about the future Sparc processor lineup.
A long way off in late 2010 or early 2011, the Sparc Enterprise server lineup gets a speed boost to 3 GHz with the Jupiter-E chips.
After that, in 2012, Sun has made no commitment to the kicker line of Fujitsu “Advanced Product Line 2″ servers coming from Fujitsu. These APL2 machines are presumably to be based on the “Venus” eight-core Sparc64-VIII processor, which has a Sparc64-VIIIfx variant aimed at supercomputers. That Sparc64-VIIIfx chip will be used in a 10 petaflops massively parallel machine being built by Fujitsu and paid for by the Japanese government under the 1.2bn Project Keisoku effort.
All of this is subject to change, and some of it most certainly will once Oracle takes control of Sun.
"ENERGY: ‘Tree power’ harvests bio-energy"

Trees can be used to power circuits, but their voltage is too small to charge conventional batteries. University of Washington (Seattle) researchers recently demonstrated a nanoscale “boost converter” that integrates the ultra-low-voltage potentials generated by trees. A tree’s output voltage can be as low as 20 millivolts, according to the researchers. They designed a circuit to nevertheless accumulate enough power over time to produce a 1.1-volt output–enough to power wireless sensors. Last year, the theory behind “tree power” was demonstrated by MIT which spun-off the company Voltree Power (Canton, Mass.) which recently won a contract from the U.S. Forest Service to supply a wireless mesh sensor network powered by trees. The Forest Service operates 28,000 U.S. weather stations, each transmiting conditions on the ground to a satellite. Voltree’s energy harvester gathers information from the surrounding forest and transmits it wirelessly to existing weather stations. The architecture extends the stations’ reach under the forest canopy for the first time. Pilot sites will be tested this fall, with the first weather station upgrades scheduled for the first quarter of 2010.

Conventional Uranium Supply and Demand
Niger Could Move Beyond Current Levels of Top Uranium Producing Nations
Niger to triple uranium production in the next few years Niger communication minister and government spokesman Mohamed Ben Omar has said his country plans to raise its annual uranium production from 3,500 to 10,500 tonnes a year in the next few years.
21 page presentation (from 2007) on Niger Uranium Limited.
100% of Niger’s Uranium Production kin 2006 came from Areva’s Somair and Cominack Mines near Arlit. A mere $10 million exploration program spread over 2 years just completed in 2009. The growth to 10,000 tons/year is coming from the meager spending on exploration.
At the beginning of 2009, Niger and the French state mining company agreed a deal to build near Arlit the Imouraren mine. Areva would hold a 66% stake to the Nigerien mining office’s 33%. At a projected output of five thousand tonnes of ore a year, it would be largest uranium mine in the world by 2012, as the SOMAIR and COMINAK mines are phased out. The deal would make Niger the second largest uranium producer in
the world, and included plans to construct a civil nuclear power station for Niger.
Niger has a substantial amount of political unrest but this unrest is not hindering exploitation or shipment of uranium.
The Imouraren mine will le launched with an initial investment of more than 1.2 billion euros (1.6 billion dollars) and create almost 1,400 jobs. Once up to full production capacity, it should be producing 5,000 tonnes of uranium a year for 35 years.
Despite the unrest France, China, India and others are in Niger and cutting deals and getting Uranium. France seems to know how to get what they want out of Africa. It is like they have many decades of experience and the willingness to do whatever it takes to supply the nuclear reactors that provide 80% of France’s electricity.
Niger to award 100 exploration permits to ramp up uranium industry . Niger Energy and Mines Minister Mamadou Abdulahi said that the country will award 100 mining exploration permits over the next two years. State-controlled French utility Areva has enjoyed a monopoly on production of uranium in Niger for some 40 years. In recent years, the
government has issued a slew of new exploration licences in an effort to diversify the uranium sector. (Resource Investor Jan 10, 2008)
Kazakhstan Situation
Kazakhstan is a dictatorship. It appears to be a stable dictatorship. Kazatomprom, a state-owned holding company produces the uranium.
Former Kazatomprom head Mukhtar Dzhakishev and other company officials illegally shifted ownership of uranium mines worth tens of billions of dollars through a network of offshore companies, the KNB security
service said.
Interpretation: An underboss over-reached and got put down by the Godfather and the Don’s security forces. Or the whatever the real story is… the top
guy decide to put down one of his underlings. The uranium is real and the reserves look real too. The Godfather in the movie had an olive oil business that was “real”.
Just like the developed countries deal with bastards who control oil, they will deal with bastards who control uranium. The bastards with oil and uranium still sell it. It is not a question of if they will sell, it is a question of price.
Wikipedia has some info on the Kazakhstan dictatorship. The years following independence have been marked by significant reforms to the Soviet-style economy and political monopoly on power. Under Nursultan Nazarbayev, who initially came to power in 1989 as the head of the Communist Party of Kazakhstan and was eventually elected President in 1991, Kazakhstan has made significant progress toward
developing a market economy. The country has enjoyed significant economic growth since 2000, partly due to its large oil, gas, and mineral reserves. Democracy, however, has not gained much ground since 1991. “In June 2007, Kazakhstan’s parliament passed a law granting President Nursultan Nazarbayev lifetime powers and privileges, including access to future presidents, immunity from criminal prosecution, and influence over domestic and foreign policy. Critics say he has become a de facto “president for life.”Kazakhstan’s National Security Committee (KNB) was established on June 13, 1992. It includes the Service of Internal Security, Military Counterintelligence, Border Guard, several Commando units, and Foreign Intelligence (Barlau). The latter is considered by many as the most important part of KNB. Its director is Major General Omirtai Bitimov.
Energy is the leading economic sector. Production of crude oil and natural gas condensate in Kazakhstan amounted to 51.2 million tons in 2003, which was 8.6% more than in 2002.
Canada Uranium Situation
The delays in bringing the Canadian mines into production are not insurmountable. Especially if supply issues were idling hundreds of billions of dollars in nuclear plants. $2-3 billion more to overcome the flooding would be made available. Just like tens of billions go to solve oil sand recovery. Higher uranium prices also would also justify the investment needed to fix the problems. Canada also continues to find 4000-7000 ppm deposits.
World Nuclear Association report on Canada’s Uranium
Canada’s production is expected to increase significantly after 2011 as several new mines, now planned or under construction, go into operation.
Uranium production in Canada is likely to increase significantly as several new mines, now planned or under construction, go into operation sometime after 2011. The two largest projects are Cameco’s Cigar Lake mine and Areva’s Midwest mine, both in northern Saskatchewan. The mill at McClean Lake has been modified to process ore from both mines. The Rabbit Lake mill will also be modified to take ore from Cigar Lake. Total production is expected to be 8,200 t/y U3O8 from Cigar Lake and 2,600 t/y from Midwest.
The proven and probable ore reserves at Cigar Lake are extremely large and very high grade. A 450-metre-deep underground mine is being developed in very poor ground conditions. Hence it will use ground freezing and high pressure water jets to excavate the ore. High-grade ore slurry from remote mining will be trucked for toll treatment at Areva’s expanded McClean Lake mill, 70 km northeast, for the first two years. The average feed grade will be 20.7% U3O8. Then, as production approaches full capacity, all of the leaching will be done at McClean Lake but about half of the uranium solution will go on to Cameco’s Rabbit Lake mill 70 km east for final production of uranium oxide concentrate. From both mills total production is expected to be 8,200 t/y U3O8 (7,000 tU/y) ramping up to this over three years from production start in 2011. Known resources are 160,000 tonnes U3O8 at about 19% average grade, and with other resources the mine is expected to have a life of at least 30 years.
Construction on the project began in 2005 with production originally scheduled to start in 2011. However, underground floods in 2006 and 2008 set the start date back until after 2011 and increased the overall cost of the project from C$660 to more than C$1billion. There will be extra requirements for pumping capacity and ground refrigeration. Some 1.3 million cubic metres of waste rock from Cigar Lake is being emplaced under water in the Sue C pit at McClean Lake, to prevent acid generation from it. Tailings will remain at Mclean Lake and Rabbit Lake.
A Cigar Lake II deposit nearby is being investigated.
In addition to mining operations planned for the near future, active exploration involving more than 40 companies continues in many parts of Canada. While exploration has concentrated on northern Saskatchewan, new prospects extend to Labrador and Nova Scotia in the Atlantic provinces, Nunavut Territory in the far north, Quebec province and Ontario’s Elliott Lake area. Resource figures quoted are generally NI 43-101 compliant.
In uranium-rich northern Saskatchewan, exploration projects are now well-advanced at three locations. The Millennium deposit (42% owned by Cameco, 30% by JCU and 28% Areva Resources) has indicated resources of 21,000 tonnes of 4.5% grade U3O8 and 4,400 tonnes of 2.1% grade inferred. Ore would be milled at Key Lake. A feasibility study on the project is under way. The Tamarack deposit associated with Dawn Lake is also a focus of interest.
The Shea Creek project (51% owned by Areva, 49% UEX Corp.) in the western Athabasca Basin has reported very high grade ore and a 900 metre shaft is being sunk to provide better access. UEX (21.3% owned by Cameco) has invested about C$30 million in exploration. UEX is also exploring the Horseshoe and Raven deposits at Hidden Bay in the eastern Athabasca basin (close to Rabbit Lake and McClean Lake). The Horseshoe deposit has indicated resources of 11,100 tonnes of U3O8 at a grade of 0.237%, and Raven has indicated resources of 7,060 tonnes at 0.02% cut-off.
Denison is actively exploring the Wheeler River deposit half way between Key Lake and McArthur River. It is a long strike from the latter and geologically very similar, with some high-grade uranium mineralisation.
The main Labrador prospect centres on the Michelin deposit, which is being drilled in a C$21million program by Aurora Energy Resources (46.8% Fronteer Development). Michelin and the adjacent Jacques Lake deposit have identified resources of 46,000 tonnes of U3O8. Michelin was originally scheduled for development starting in 2010, but a provincial government moratorium until 2011 will delay the project. In Nova Scotia, exploration has been proposed at Millet Brook, but it awaits a review of a 1985 moratorium on uranium mining in the province.
Far north in the Nunavut Territory, a joint venture headed by Areva is conducting a feasibility study on the Kiggavik uranium deposit in the Thelon Basin, with an estimated 67,000 tonnes U3O8 at 0.24% grade. The indigenous Inuit organization, Nunavut Tunngavic, reversed its previous ban on uranium exploration and mining in 2006, but the project has faced opposition from other groups. The project involves the development of three open pit mines at Kiggavik and both an open pit mine and an underground mine at Sissons. Areva and its partners, JCU (Canada) Exploration and Daewoo, hope for a start-up of the mine and mill complex in 2015.e
Also in Nunavut, at Amer Lake, Uranium North Resources has reported resources of 8,770 t U3O8.
In Quebec, exploration is underway at several locations with a total of more than 40,000 tonnes of indicated or inferred deposits. Strateco Resources has reported indicated resources of 1,700 t U3O8 grading 0.68% and inferred resources of 6,000 tonnes grading 0.44% at its Matoush deposit in the Otish Basin of central Quebec. The company completed a scoping study in 2008 and will begin underground development in mid-2009, with a view to mine production in 2012. Azimut Exploration has committed C$42 million to uranium exploration, mainly for the Katavic project in Quebec’s northern Nunavik region and other prospects in the Ungava Bay region further north. Uracan Resources reports 18,400 tonnes of U3O8 of inferred resources at its North Shore prospect in eastern Quebec.
The Elliot Lake area of Ontario, which was the centre of Canada’s early uranium mining, is again attracting exploration. In September 2008, Pele Mountain Resources commenced the permitting process for its Eco Ridge underground uranium mine and processing facility in the region. Eco Ridge contains indicated resources of 5,700 tonnes U3O8 and inferred resources of 37,300 tonnes U3O8.
In British Columbia, the Blizzard prospect south of Kelowna, which was first explored in the 1980s, has been revived by Boss Power. The company has challenged a provincial government moratorium on exploration and mining imposed in April 2008, and the British Columbia government has indicated the Blizzard project may be able to go forward.
Uranium exploration appears to be on the upswing throughout Canada. Cameco spent C$57 million on exploration in 2008 (plus a further $32 million in three strategic partnerships with junior explorers) and plans C$50-55 million for 2009, mainly in Saskatchewan, Nunavut and the Northwest Territories. In late 2007, Cameco announced an agreement with the Russian company Uranium Holding ARMZ (JSC Atomredmetzoloto)
to create a joint venture to explore and mine uranium in northwest Russia, Saskatchewan and Nanavut.
