The wait is almost over!  Exactly four months after “Justice” left us hanging, Stargate Universe fans are eagerly anticipating the show’s return to Syfy Channel in the U.S. this Friday at 9 p.m. (8 Central).  But many want to know:  Why was the mid-season break so long? We asked Stargate fans via Twitter what their ideal length would be for the mid-season break, and got a variety of responses.  But we also heard straight from Syfy’s Craig Engler, Senior V.P. of Syfy Digital, who said, “No mid-season break could mean [32] weeks or more between full seasons.  Basically, every schedule choice has a trade-off. … We split seasons so there are not huge gaps between full seasons.”

At first glance, D-Wave Systems looks like any other well-appointed office, with an open reception area and conventional cubicles. But one glance at the wall beside the receptionist and you know the average IQ here is intimidatingly high — it’s literally covered in plaques from the U.S. patent office featuring 19th century lettering and incongruously describing patents for superconducting qubit-based microchips.

Willow Garage is organizing a workshop at the IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR) 2010 in San Francisco to discuss the intersection of computer vision with human-robot interaction. Willow Garage is the hardware and open source software organization behind the Robot Operating System (ROS) and the PR robot development platform. Here’s a recent video from Willow Garage of work done at the University of Illinois on how robots can be taught to perceive images:

Walking, swallowing, respiration and many other key functions in humans and other animals are controlled by Central Pattern Generators (CPGs). In essence, CPGs are small, autonomous neural networks that produce rhythmic outputs, usually found in animal's spinal cords rather than their brains. Their relative simplicity and obvious success in biological systems has led to some success in using CPGs in robotics. However, current systems are restricted to very simple CPGs (e.g., restricted to a single walking gait). A recent breakthrough at the BCCN at the University of Göttingen, Germany has now allowed to achieve 11 basic behavioral patterns (various gaits, orienting, taxis, self-protection) from a single CPG, closing in on the 10–20 different basic behavioral patterns found in a typical cockroach. The trick: Work with a chaotic, rather than a stable periodic CPG regime. For more on CPGs, listen to the latest episode of the Robots podcast on Chaos Control, which interviews Poramate Manoonpong, one of the lead researchers in Göttingen, and Alex Pitti from the University of Tokyo who uses chaos controllers that can synchronize to the dynamics of the body they are controlling.

Just as photographic film was mostly replaced by silicon image chips, now quantum film threats to replace the conventional CMOS image sensors in digital cameras. Made from materials similar to conventional film—a polymer with embedded particles—instead of silver grains like photographic film the embedded particles are quantum dots. Quantum films can image scenes with more pixel resolution, according to their inventors, InVisage Inc., offering four-times better sensitivity for ultra-high resolution sensors that are cheaper to manufacture.

Anyone can bake a cake, but while some chefs bake dry, uninspired bricks of dough, there are other chefs who make cakes we would die for. The ingredients may be the same, but the outcomes are so very different. This is also the case between average electronic products and world-class, market-changing products. One of the most recent technical sensations is the capacitive touch screen. But what makes some touch screen-based products amazing, while others get such poor reviews?

March has seen two significant announcements from FPGA start-ups with innovative architectures: Tabula, with their time-domain-multiplexed architecture, and TierLogic, implementing their routing switches in a layer of thin-film transistors. Both approaches promise to significantly reduce the die size and cost of high-end FPGAs. But before these announcements broke, a relatively unnoticed paper at February's International Symposium on FPGAs described what may be the most radical technology of them all: FPGAs using electromechanical relays. No, this is not an early April Fool's joke, nor is it one of those "let's see if anyone will publish this one" academic exercises. The paper presented work by professors and students at the Stanford University departments of electrical engineering and computer science, and researchers at Altera Corp. The work was supported in part by DARPA funding.
