ASSET’s Dispatcher for ScanWorks applies tests simultaneously to unlimited PCBs
The circuit boards being tested can be local to the ScanWorks platform or on the other side of the globe. ASSET is the leading supplier of open tools for embedded instrumentation for design validation, test and debug.
“Dispatcher for the ScanWorks platform is particularly cost-effective in high-volume manufacturing or where multiple boards are being tested in an environmental chamber,” said Dave Bonnett, technical marketing manager. “Testing many boards in parallel reduces the number of testers and makes operators more productive.”
Dispatcher works with ScanWorks’ Remote Instrumentation Controller Model 1000 (RIC-1000), a self-contained intelligent controller that connects a unit under test (UUT) to ScanWorks over an Ethernet or Internet connection and applies tests or diagnostics to the UUT. For Dispatcher to manage the test and diagnostic process on multiple UUTs, each UUT must be connected to an RIC-1000.
Dispatcher also simplifies the tracking of test results from multiple circuit boards. Test results are formatted as XML files to ease data retrieval and processing. In addition, Dispatcher comes with an application programming interface (API) that simplifies the customization of the user interface or Dispatcher’s integration into test environments such as National Instruments’ LabVIEW or TestStand.
Pricing for a Dispatcher license for a single UUT starts at $4,995. Dispatcher will be generally available during the third quarter of 2009. Initially, Dispatcher supports boundary scan test and in-system programming. Support for other embedded instrumentation test technologies will be available soon.
Space elevator Games Delayed at Least 4 Weeks
This resulted in a safety device dropping the line – which means we’ll have to do this yet again, until we get it right, and so the games cannot proceed as planned on August 5th. The likely minimum delay is probably 4 weeks.
Aviation week has coverage of the problem
A technical issue with a helicopter cable system is forcing the Spaceward Foundation to postpone the Space Elevator Power Beaming Challenge Games originally scheduled for this summer at NASA’s Dryden Flight Research Center.
The 3/16th inch thick steel cable is suspended beneath an Aris Helicopters-operated Sikorsky S-58T, but issues reoccurred with the winch and pulley system similar to those which earlier this month forced organizers to reschedule the contest to Aug. 5-7. In the latest tests over the dry lakebed at Edwards Air Force Base last week, as the helicopter was hovering above the anchor point, one of the safety release mechanisms gave way unexpectedly. The release mechanism is designed to drop the cable should the pull strength exceed 3,500 pounds, but officials say that according to strain gauges the pull tension was “nowhere near 3,500 pounds.”
Spaceward, which is trying to develop a stable racetrack for the contests to use, now plans to re-examine this system and determine what changes may need to be made. Officials believe the games may be rescheduled for September or October, given the time required for reruns of the tests with the teams and the helicopter.

General Fusion Raises USD$9 million
H/T to Xconomy for the details on this fund raising.
General Fusion had been award C$13.9 million from the Canadian government.
General Fusion is using the MTF (Magnetized Target Fusion) approach but with a new, patent pending and cost-effective compression system to collapse the plasma. They describe the injectors at the top and bottom of the above image in the new research paper. The goal is to build small fusion reactors that can produce around 100 megawatts of power. The company claims plants would cost around US$50 million, allowing them to generate electricity at about four cents per kilowatt hour.
If there are no funding delays, then in 2010-2011 for completion of the tests and work for an almost full scale version (2 meters instead of 3 meter diameter).
The third phase for General Fusion was to raise $50 million for a net energy gain device with a target date of 2013 if the second/third phase are roughly on schedule. [The canadian government funding and private funding could take General Fusion all the way through the third phase]
If they get $300-500 million for commercialization, the first commercial scale unit could be 2016-2018.
"MEMS: Silicon Clocks raises $10.3M to commercialize CMOS+MEMS"
Silicon Clocks Inc., a Fremont, Calif., fabless vendor of microelectromechanical system (MEMS) timing chips, has landed $10.3 million in a Series C financing round led by new investor Silicon Labs (Austin, Texas) joined previous investors Charles River Ventures, Formative Ventures, Lux Capital and Tallwood Venture Capital. Silicon Clocks’ will use the money to ramp up production of its J-Series phase-locked loop technology, which produces low-jitter oscillators in the 100- to 700-MHz range using a proprietary CMEMS (CMOS + MEMS) process.

"MEMS: world’s thinnest accelerometer slims consumer gear"
STMicroelectronics has fielded a 0.75-mm-thick three-axis microlectromechanical system (MEMS)-based accelerometer that it says will let even ultrathin consumer platforms offer advanced user interface features. The LIS302DLH is the thinnest member of ST’s Piccolo family of ultrasmall 16-bit MEMS chips, which are housed in 3 x 5-mm packages. ST said its digital three-axis accelerometer offers built-in motion sensing, orientation awareness, freefall detection and vibration monitoring. The device has a power-saving shutdown mode that awakens it automatically when motion is sensed. Acceleration measurements range from +8 to –8 g’s. The LIS302DLH uses an SPI serial interface.
