  • Compare The Process Between Engstrom’s Internet Bill Of Rights And ACTA

    As a bunch of countries and lobbyists continue to debate ACTA in secret, it’s interesting to compare that to an ongoing effort by Christian Engstrom, one of two Pirate Party representatives in the European Parliament, to create an Internet Bill of Rights by asking people what they want. Which one sounds more like government for the people, by the people?

  • Small Business Confidence Collapsed From October To November

    freefallwaterfall.jpgDavid Goldman spots the results from the Discover Small Business Index and it confirms what many other indicators are showing: Something happened in November to derail the recovery.

    ———

    Economic confidence among America’s small business owners plummeted in November, as more owners cited serious concerns about cash flow and saw economic conditions for their own businesses getting worse. The Discover Small Business Watch index fell 12 points in November to 76.5 from 88.5 in October.

    • The mood of small business owners generally has soured in November for three straight years, as economic confidence dropped from October to November in 2007 and 2008. The November 2008 index of 67.5 is the low point for the Watch since it started in August 2006.
    • 52 percent of owners say they have experienced cash flow issues in the past 90 days, up from 44 percent in October. Forty-one percent of owners say they have not experienced cash flow issues, which is the lowest response in this category since the Watch began. The remaining 6 percent said they weren’t sure.
    • 53 percent of small business owners see conditions getting worse in the next six months, up from 43 percent in October; while 19 percent report that conditions are improving, a sharp decline from 29 percent in October; 23 percent see conditions as the same, and 5 percent weren’t sure.
    • 62 percent of small business owners rate the economy as poor, an increase from 55 percent in October; 30 percent rate it as fair, and 8 percent say it is good or excellent.      
    • 53 percent of small business owners think the overall economy is getting worse, up from 44 percent in October but still significantly lower than the 69 percent of owners who felt that way in February 2009, the last time the Watch index was this low. For November; 28 percent say the economy is getting better, down from 35 percent in October; 16 percent see it staying the same, and 3 percent are not sure.

    Only 11 percent of Small Businesses Expecting Increased Sales This Year

    • Small business owners have a glum outlook on the holiday season: Only 11 percent expect to see more business this year over last, while 46 percent of them are expecting less business than last year, an increase over the 40 percent who said the same in November 2008; 39 percent anticipate 2009 sales will be about the same as last year, and 4 percent weren’t sure.
    • For many small business owners, the holiday season is not necessarily their busiest time. A majority of owners, 56 percent, say that the holiday season falls somewhere in between being their busiest and the slowest time of year, 29 percent say this is their slowest time, and 13 percent say it is the busiest.

  • How Just 60 Employees At Ginnie Mae Direct $826 Billion In Mortgage Lending

    vampiresquid.jpg

    Here’s another vampire squid worthy of public ire.

    The Government National Mortgage Association (Ginnie Mae) has rapidly grown into a mortgage giant with some questionable mortgage lending partners.

    While CEO pay and free markets receive all the heat for the housing crisis, a new report describes in detail how Ginnie Mae was, and is, at leading edge of housing crisis.

    What Ginnie has become.

    Washington Post: “Mortgage lenders often want to bundle the loans they’ve made into securities and sell them to investors. Ginnie Mae guarantees those securities….

    In the past year, nearly one in five new mortgages — both good loans and bad — were put into securities guaranteed by Ginnie Mae.”

    How rapidly its grown.

    “Only a few years ago, Ginnie Mae was a bit player in the mortgage market, backing just 4 percent of new mortgages. Then the housing market melted down, and many of the banks and other lenders that had made risky but highly popular loans got out of the business….

    In the past two years, the total value of Ginnie Mae’s guarantees for principal and interest on home loans jumped 43 percent, to $826 billion.”

    Why it’s work is questionable.

    “Lenders with spotty histories and poor financial health have sold nearly $100 billion in loans packaged into Ginnie Mae-guaranteed securities in the past two years, according to calculations based on data provided by Inside Mortgage Finance, a trade publication.”

    How 60 people control so much power.

    “Joe Murin, who recently left as head of Ginnie Mae to return to the private sector, acknowledged that the enormous growth of Ginnie Mae’s portfolio has increased the risk for the agency. He said the main problem is that the agency doesn’t have the staff needed to track the growing number of issuers. Despite the huge increase in issuance, Ginnie Mae’s staffing has hovered at just over 60 employees.”

  • H1N1 (swine flu) weekly update: Dec. 1- 8

    fluDec9Here are this week’s H1N1 updates from the HealthMap team of the Children’s Hospital Informatics Program.

    • The World Health Organization (WHO) reports that “Disease activity has peaked and is declining in North America and has either recently peaked or is currently peaking in much of western and northern Europe.” In other good news, WHO also reports no signs of widespread resistance to Tamiflu.
    • Nevertheless, the WHO has clearly stated it is too soon to call the pandemic over. The global death toll from H1N1 rose to 8,768 as Cyprus, Albania, and the Gaza Strip recorded their 1st H1N1 deaths. The Netherlands saw their first Tamiflu-resistant death.
    • In the United States, only half of all states reported widespread flu activity, down from 43 states only two weeks ago. England reported new cases were half of the previous week’s number.

    * Please note that this post will conclude our weekly H1N1 blogs. While the pandemic is far from over, reports of first cases and deaths are less common as H1N1 has spread throughout much of the globe. Numerous H1N1 vaccines have been developed in countries all over the world, and the vaccine shortages seen earlier this year have abated.

    HealthMap continues to track H1N1 and all other infectious diseases at http://www.healthmap.org. For the latest disease alerts, you can also follow us on twitter. We hope the H1N1 blogs have been informative and helpful.

  • Tuned Mass Dampers

    Wide span structures (bridges, spectator stands, large stairs, stadium roofs) as well as slender tall structures (chimneys, high rises) tend to be easily excited to high vibration amplitudes in one of their basic mode shapes, for example by wind or marching and jumping people.

    Low natural frequencies are typical for this type of structures, due to their dimensions, as is their low damping. With GERB Tuned Mass Dampers (TMD), these vibrations can be reduced very effectively.

    The TMD may consist of:
    Spring

  • Temperature measurement close to the measuring point

    To measure temperatures directly at the sensor in a quick and precise way, ADDI-DATA offers the new intelligent Ethernet system MSX-E3211 with 24-bit resolution. Two versions are available: one version with 16, the other with 8 differential inputs for connecting thermocouples or resistance temperature detectors (RTDs), such as Pt100 or Pt1000. The Ethernet system is equipped with an ARM®9 processor and 64 MB SDRAM. This allows the measurement values to be acquired, processed and stored directly on the spot. The MSX-E3211 can work both in stand-alone operation and with higher-level controls, using standard Ethernet. For reliable use in harsh industrial environments, the MSX-E3211 is protected by a robust metal housing and has been equipped with a number of protective circuits. It also complies with the IP 65 degree of protection and is designed for the extended temperature range from -40 °C to +85 °C. With the DatabaseConnect software, the measurement values are provided in databases.
    The parameters of the measuring system can be configured by mouse-click on the MSX-E3211 website. No knowledge of programming is necessary. Directly on the website, the user can also monitor the measurement values which the system acquires. The acquisition is launched either by an external 24 V hardware trigger signal, by software command or by an additional MSX-E-type Ethernet system. Two acquisition modes are possible: Auto-refresh mode, which automatically updates the acquired data in the background, and Sequence mode, with which the data is acquired in packets. The “Autogain” functionality automatically adapts the gain of the signal to the measurement range. Errors can be quickly diagnosed by means of LEDs, which provide information on the current status of the MSX-E3211. For acquiring more than 16 sensors, several MSX-E3211 Ethernet systems can be cascaded using the integrated Ethernet switch. This also makes it possible to acquire different temperature sensors. The channels of the different systems can be acquired simultaneously thanks to synchronisation in the µs range outside the Ethernet network.

  • New mechanical hygrostat

    The newest addition to the Fandis family of thermo-regulators is a mechanical hygrostat, developed and produced in its laboratories.

    This new model has been renewed fundamentally in the aesthetical aspect, engineering a more fashionable design with rounded shapes and optimizing visually the temperature setting system by pad printing of the values directly onto the housing.

    The new change-over hygrostat is suited for application on 35mm DIN rail and offers a setting range from 10 to 90% relative humidity, satisfying the demand of the industrial automation sector.

  • GEFRAN RENEWS ITS SERIES OF MAGNETOSTRICTIVE TRANSDUCERS WITH SSI INTERFACE

    Gefran has renewed its series of magnetostrictive transducers with SSI interface, increasing performance to satisfy market demands. The electronics has been completely redesigned to improve the linearity and communication of all models.

    Among Gefran’s magnetostrictive transducers, SSI interface models have an extremely wide range of application. This protocol, with its immunity to noise and high adaptability to the communication interface, provides very precise measurement reads.

    Among the principal innovations is the new “internal linearization” option, which provides linearity up to 4 times higher than the standard version by performing linearity compensation in the electronics.

    The entire SSI series has been given new electronics compatible with EMC standards and is more resistant to power surges. The reduction in overall noise improves transducer communication. In addition, the communication structure has been aligned in all versions (with and without the oversampling algorithm), making the entire series more compatible with SSI sensors made by other companies.

    With regard to technical specifications, maximum working temperature has been raised to 90°C and current input has been halved, dropping to 50 mA, the lowest level on the market for this product!

    As for the models, the version with MK4-S profile maintains its mechanical characteristics, with the addition of a new model with M16 Binder 7-pin DIN 45329 connector.
    On the other hand, the rod version has been completely redesigned, evolving from the IK2 series with hexagonal head to the IK4 series with innovative cylindrical head, from which it acquires all its mechanical specifications. As in all of the other IK4 models, the entire electronics of the IK4-S transducer can be removed by unscrewing the ring-nut seal on the head and extracting the connector head to which it is attached. This means that in case of damage, the electronics can be replaced without removing the transducer, an essential feature in applications such as installations inside hydraulic cylinders. Working on the transducer without removing it avoids opening the cylinder, oil leaks, and resetting the hydraulic system at the end of maintenance.

  • Book Review: The Silent Gift By Michael Landon Jr.

    Review by Lauryn Abbott

    This was a difficult book for me, as a mother, to read. The Silent Gift, (Bethany House/ Oct 2009): Michael Landon Jr. and Cindy Kelley have written a moving book that is both heartbreaking and heartwarming. Set in the time of the Great Depression of the 1930s, it’s a painful reminder of how bad things once were for children who weren’t “normal” and the parents who didn’t want to merely institutionalize them.

    From beginning to end, the story is gripping, emotionally charged, and dramatic. If you’re looking for an easy, lighthearted read, The Silent Gift is not for you. But if you’re looking for a book with depth and heart, filled with twists and turns, that thoroughly captivates you, then The Silent Gift is definitely the one for you. I highly recommend it!

    Michael Landon, Jr. is an American actor, director, and producer.  He is the son of the late actor, Michael Landon.  He is also well known for his writing:

  • Marissa Mayer Talks About the Future of Search, Moving Beyond Text Search

    While the Le Web conference in Paris was focused on startups, there were a lot of big names talking and making announcements as well. Google was represented at the highest level with VP of Search and User Experience Marissa Mayer discussing some of the new products from Google, as well as some future plans in an interview with TechCrunch’s Mike Arrington.

    The interview starts off with a look at Google’s most recent products which all seem to be pointing to its plans beyond the text search. It recently launched Google Goggles, its experimental approach to visual search which allows users to take a picture of an object and get more information on it automatically from Google using a variety of technologies with the focus being on OCR (optical character recognition) and image recognition. Mayer said that visual search was still very much in the early days and that the technologies had to get significantly better before it became a viable alternative for the mainstream.

    She added that voice recognition technologies were much further along. Google Voice search also got updated recently and the tool is becoming a viable option, especially on mobile devices. This is even more important now that mobile search is seeing a huge growth in usage spurred by the increasingly powerful mobile de… (read more)

  • Windmills Are A Great Way To Cheat Carbon Credits

    chinawindmills.jpg

    Here’s one of the problems with carbon credits — It is very easy for developing countries to game the system. They can essentially say that they were planning to do something environmentally damaging, then switch to a ‘greener option’ and collect carbon credit income. Yet if the greener option was their original intent then the credits haven’t actually created any additional carbon savings.

    The latest evidence comes from China where the U.N. on December 4th refused to approve ten wind farms near Harbin due to the fact that the  projects would have happened with or without the sale of carbon credits.

    Projects like these get paid for doing absolutely nothing extra. To be fair though, it’s not clear whether the real problem here is China, or rather the way carbon credits are calculated. They didn’t write the rules after all.

    Business Week:The 10 Chinese wind farms were rejected, in part, because U.N. officials fear Beijing is actually reducing its financial support for wind power as a gambit to help the country’s clean-energy projects qualify for carbon payments from abroad.

    The Chinese government may be doing this by cutting the rates the wind farms will be paid for electricity, according to the U.N. officials.

    The Harbin wind farm’s developers initially estimated the project would earn an annual profit of 8.76%. That would have made the wind farm ineligible for carbon funds, since the cutoff to benefit from credit sales is 8%.The Chinese government apparently responded to the situation by reducing what it had been expected to pay for Harbin’s electricity, pulling the project’s profit margin below 8%.

    On Dec. 4, the U.N. announced that it would stop what appears to be China’s attempt to game the system. Lex de Jonge, chairman of the U.N. committee overseeing carbon credits, said in a statement that his panel “must safeguard the environmental integrity of the [carbon market].” He added: “This means registering only projects that would produce emission reductions that are additional to those that would take place without the project.”

  • What the Dog Saw and Other Adventures by Malcolm Gladwell

    Confession: This is not my favorite Malcolm Gladwell title. But that’s not to say that I didn’t enjoy parts of it more than probably 75% of the titles collected in this whole blog. Really. Gladwell is one phenomenal, erudite entertainer … and that modern technology magically allows me to  be read to by Gladwell himself has got to be one of life’s best little Luddite joys.

    The contents here are not new … instead, these are Gladwell’s 19 “favorites” among the “countless articles” he’s written for The New Yorker since 1996 where he’s been and still is a staff writer. “Curiosity about the interior life of other people’s day-to-day work is one of the most fundamental of human impulses,” writes Gladwell in his preface to this collection, “and that same impulse is what led to the writing you now hold in your hands.” Or, in my case, in my earphones (ancient Walkman leftovers which are still the only ones that actually fit my mutant ears).

    Gladwell’s own curiosity, coupled with his uncanny ability to ask the right questions to get the most fascinating answers, is showcased throughout this collection. He presents his stories in three sections: Part One covers what Gladwell calls “varieties of minor genius,” Part Two examines “theories … ways of organizing experience,” and Part Three “wonders about the predictions we make about people.” Among the 19 are definitely standouts that make for fabulous intellectual fodder … why one ketchup dominates amidst dozens and dozens of various mustards, how the story of hair dye contains the post-World War II history of American women, how the birth control pill just might have passed the Papal censors with the right marketing twist, what mammograms and the most advanced military photography commonly can’t tell you, and how Bryony Lavery plagiarized Gladwell’s work for her Tony-nominated play Frozen and got invited to his kitchen table …

    And about that dog … the two strongest pieces put man’s best friend center-page … although in unexpected lights, for sure. The eponymous essay about the so-called ‘dog whisperer’ is the best of the bunch, offering a memorable glimpse into Cesar Millan’s own life and his truly gifted canine communications. The collection’s final essay – a heartbreaking piece about punishing (and destroying) the wrong breed! – begins with attacking pit bulls but proves once again that there are no bad dogs, just irresponsible, greedy, violent people … ah, humanity … or lack thereof, alas.

    Personal Gladwell-groupie rankings: Outliers remains my all-time favorite, then Blink, then Tipping Point. Also, if you want to read the rest of Gladwell’s New Yorker essays, even if they’re not his own favorites, you can find them all on his website by clicking here.

  • SMAC Electric Actuators – Serious Competition for Pneumatics

    SMAC Inc., Carlsbad, California. SMAC aims to replace 5 percent of pneumatic devices that are used in today’s industrial applications within the next 5 years. SMAC electric direct drives utilize moving coil technology, are versatile, long life, robust, and provide high reliability in comparison to conventional pneumatic devices.

    The linear movement is generated by a voice coil and high strength neodymium magnets. The coil is mounted on a linear guide which is the only contacting part; increasing the life of an electric actuator to more than 10 times that of a pneumatic actuator. SMAC moving coil actuators have no mechanical backlash which significantly increases position accuracy and speed. Some units can reach acceleration up to 50G.

    The position repeatability of +/-2 encoder counts is controlled by a linear encoder with a resolution of 20, 5, 1, 0.5, 0.1 or 0.05 microns. SMAC electric actuators combine high precision and accurate control of force, speed and position. They are utilized for high precision applications such as laser cutting, part feeding and component pick and place. Precise force control eliminates any damage when soft-landing on a surface.

    Complete direct drive systems with actuator, controller and cable are priced from 1000 US dollars. This price favorably compares when taking into account the unit’s long life, low maintenance costs, and exceptional reliability. The low power consumption of SMAC actuators means that the energy they use is typically less than 5 percent of a comparable pneumatic device.

  • ÖLFLEX® CHAIN Power Chain Cable Instead Of Rules & Regulations Maze

    It’s not easy for export-oriented machine and plant manufacturers, because the maze of rules and regulations in the USA poses considerable problems to many. One of the reasons: more and more federal states are adopting the new National Electrical Code (NEC) Edition 2008. A reference is made there, in Article 670 (Industrial Machinery), to NFPA 79 Edition 2007. According to this, for example, the use of AWM leads (Appliance Wiring Material) is only possible to a limited extent. In the meantime, 29 of the 50 US federal states require this new NFPA 79 standard to be followed. In the other states, local inspectors still decide what is allowed and what not. Conclusion: anyone wishing to be certain and not looking to encounter any operating prohibitions is best advised to comply with the new NFPA 79-conform and listed leads.

    The Stuttgart-based Lapp Group has already aligned itself to the latest US standards and at this year’s SPS/IPC/DRIVES (24th to 26th November 2009) in Hall 6, Stand 350, it will be showcasing its extended, comprehensive product range of new UL-listed leads.

    Much sought-after, in particular, are the new ÖLFLEX® CHAIN 879 and its screened version ÖLFLEX® CHAIN 879 CY. “Because of the high demand, we have already had to boost availability for our customers”, said Product Manager Volker Huber. This UL MTW listed, highly-flexible cable for power chains is approved for all wiring between constantly moving machinery and machine parts located in power chains as well as industrial machines. The lead is enormously oil-resistant (OIL RES I & OIL RES II). This is why it is especially suited for use in wet areas with metalworking cutting machine tools. Its highly-flexible structure enables small bending radii and protects the conductors from breakage due to vibrations. It is also flame-retardant and designed for up to eight million alternate bending cycles. The screened CY version also has a tin plated copper wire screening braid.

    The NFPA 79-conform cable range also includes ÖLFLEX® connecting and control cables as well as UNITRONIC® data cables in the TRAY II, CONTROL TM, CONTROL M, VFD, Auto-X, Auto-I versions and the UNITRONIC® 300 data cable.

  • Laser-based systems to substitute isotopic and x-ray systems

    LAP has further enhanced the accuracy of its CALIX sensors in strip gage measuring applications. The systems now reach the same or even superior levels of precision as radiometric systems, which so far have been the most commonly used systems in rolling mills. Thanks to their compactness, the new systems can be easily integrated into existing process lines, without having to take any conversion measures on site. Their operation does not require any radiation protection measures to be taken.

    LAP has developed a new generation of laser-based thickness gages, representing a cost-effective alternative to radiometric systems. Comprehensive measurements have shown that the new CALIX sensors operate with a measuring accuracy of +/- 4 µm and a repetition accuracy of +/- 0.4 µm (2 Ã) over the complete measurement range of 0.02 – 30 mm.

    CALIX systems work entirely independently of the strip properties. Therefore it is not necessary to input any chemistry and density data for the strip or store such information in a database, as required by radiometric methods. This feature prevents any hidden, material-inherent error propagation due to material inhomogeneities in the strip material. “Thickness noise” known from radiometric systems or the source noise occurring with isotopic systems are things of the past.

    The high level of measuring accuracy and the compact design make CALIX systems a highly attractive alternative to radiometric systems when building completely new or upgrading existing rolling mills. Due to the moderate expense of the optics and evaluation electronics and the low calibration and maintenance effort, CALIX is a highly cost-effective solution.

    As the measuring frame is extremely compact – the system requires a maximum clearance of 400 mm in the rolling direction – existing radiometric systems can be replaced without rebuilding the mill equipment. Existing devices for retracting the frame can be continued to be used.

    There is up to 200 mm clearance between the legs of the C-frame, avoiding any risk of collision when measuring wavy material or during strip threading. From now on LAP will deliver the CALIX systems with leg lengths of 1,000 mm. A measuring frame can accommodate several pairs of sensors for different measuring tracks. As an alternative option, it is also possible to use a measuring frame equipped with only one pair of sensors and traverse it across the width of the strip.
