Developments

We all go through phases where we feel like we’ve seen every possible Kickstarter project that we’d ever want. And then one like Mycestro comes along and reminds us that this is just the tip of the iceberg. It’s a 3D mouse that you strap to one of your fingers and it looks like it could become a huge asset for multi-tasking. If you think about how you use your computer, be it a desktop or laptop, you know that your hands move from the keyboard to the trackpad or mouse constantly, over and over again. It’s wasted movement for the most part, especially when you see the possibilities that Mycestro unlocks. The only thing left is for it to get funded, because it looks like all of the prototypes work perfectly. Features include touch buttons that allow you to navigate your computer without the need for moving your entire hand to a dedicated area on a computer, thanks to 3D technology and space recognition:  Specifications for the 3D Mouse: – Size of a wireless earpiece. – Light, weighing next to nothing. – Internal battery can be charged via USB. – Battery life is estimated to be eight hours depending on usage. – Two different replaceable clip sizes. This isn’t a completely perfect situation though, as you’ll have to re-learn how to use a mouse. The other thing is that if you’re in a coffee shop or somewhere in public, people are going to look at you like you have some issues. The thing is called the Mycestro for a reason; it looks like you’re conducting your own private orchestra. In other words, you’re going to look weird. If you’re okay with that, then the benefits outweigh the public shame and looks you might receive. The device works from 30 […]

Allen-Bradley ControlLogix 24vdc I/O modules, used with the ControlLogix 5570 family of PACs, can significantly improve total System Response Time (SRT) through new hardware technology and peer-to-peer communication capabilities that significantly reduce the time it takes for modules to communicate with the controller. Since SRT equates to the time required for input module response, controller processing and output module response, reducing I/O latency results in higher machine speeds for increased parts production. For even faster performance, the new modules also function in peer-to-peer mode, bypassing the controller entirely by establishing in-chassis connections that allow I/O modules to communicate directly with each other. Shifting task management to the I/O modules can relieve a controller of the overhead required to process and direct I/O modules, helping improve reliability in program execution and throughput. In peer-to-peer mode, input to output response time can be less than 100 microseconds.The peer-to-peer capabilities are ideal for applications with fast detect-energize sequences, such as high-speed parts rejection. OEMs are tasked with building faster machines as manufacturers seek to increase productivity and throughput. PACs are getting faster, but a controller’s processing capacity is not the only factor influencing throughput. For end users and machine builders with high-speed sequential control applications, our new I/O can increase the speed at which machines can function, resulting in higher parts production per shift for the customer.      

Many works of science fiction have imagined robots that could interact directly with people to provide entertainment, services or even health care. Robotics is now at a stage where some of these ideas can be realized, but it remains difficult to make robots easy to operate. One option is to train robots to recognize and respond to human gestures. In practice, however, this is difficult because a simple gesture such as waving a hand may appear very different between different people. Designers must develop intelligent computer algorithms that can be ÔtrainedÕ to identify general patterns of motion and relate them correctly to individual commands. Now, Rui Yan and co-workers at the A*STAR Institute for Infocomm Research in Singapore have adapted a cognitive memory model called a localist attractor network (LAN) to develop a new system that recognize gestures quickly and accurately, and requires very little training. “Since many social robots will be operated by non-expert users, it is essential for them to be equipped with natural interfaces for interaction with humans,”says Yan. “Gestures are an obvious, natural means of human communication. Our LAN gesture recognition system only requires a small amount of training data, and avoids tedious training processes.” Yan and co-workers tested their software by integrating it with ShapeTape, a special jacket that uses fibre optics and inertial sensors to monitor the bending and twisting of hands and arms. They programmed the ShapeTape to provide data 80 times per second on the three-dimensional orientation of shoulders, elbows and wrists, and applied velocity thresholds to detect when gestures were starting. In tests, five different users wore the ShapeTape jacket and used it to control a virtual robot through simple arm motions that represented commands such as forward, backwards, faster or slower. The researchers found that 99.15% of gestures were correctly […]

Tensions continue to run high over the inclusion of aviation in the EU’s Emissions Trading System (ETS), after Indian government officials confirmed that New Delhi would be asking its airlines not to participate in the scheme. Meanwhile, the trade group representing the largest US airlines is now calling upon the White House to pursue a case against the Brussels plan at the International Civil Aviation Organization. “Though the European Union has directed Indian carriers to submit emissions details of their aircraft by March 31, 2012, no Indian carrier is submitting them in view of the position of the government,” India civil aviation minister Ajit Singh said. “Hence the imposition of a carbon tax does not arise.” The move makes India the second country to take concrete action against the inclusion of aviation in the Brussels scheme, with China having earlier banned its own airlines from complying with the EU ETS without government approval. Beijing has also reportedly halted the orders of US$14 billion worth of jets from Europe’s flagship airplane manufacturer, Airbus, in response to the aviation emissions rule. However, this claim has been contested by China’s aviation regulator, Li Jiaxiang, who indicated in an interview with Bloomberg that the country’s airlines have not been barred from buying Airbus planes. The US has also warned that it could take ‘appropriate action’ in response to the scheme, but has yet to take any concrete steps. However, Airlines for America – the trade group that had, together with three US airlines, unsuccessfully challenged the legality of including aviation in the scheme at the European Court of Justice – is nowÊcallingon the administration of US President Barack Obama to bring a case through the International Civil Aviation Organisation (ICAO), the UN civil aviation body. “There is a clear path for the United States […]

  Cutting technologies are continuously evolving, and one of the most significant recent advances in the field is fiber laser. Fiber laser technology has been available for only about three to five years; so many companies are still getting acquainted with it, and are just beginning to appreciate the differences between fiber and the more ‘traditional’ CO2 laser. Of the key thermal cutting methods involving oxyfuel, plasma, and laser technologies, laser cutting offers the best cut quality, especially for fine features and holes that have less than a 1:1 diameter-to-thickness ratio. This makes laser the most appropriate method for stringent precision cutting needs in any industry. And within the laser cutting category, fiber laser is garnering a lot of attention because it offers the speed and cut quality of CO2 laser, but costs significantly less to maintain and operate. This makes fiber laser so promising as a cutting technology that many experts believe it will soon overtake other laser systems. Key advantages of fiber cutting In CO2 laser, CO2 gas is involved in the transmission of the beam. In fiber laser, however, transmission works through diodes and fiber cables. Instead of relying on mirrors to transfer the light beam, fiber laser systems rely on multiple solid state pump diodes to generate a laser beam, which is then transmitted through a flexible fiber cable to the laser cutting head. This offers a number of benefits, the first being table size. Unlike gas lasers, where mirrors must be a set distance apart, there is no size restriction for fiber laser. It is even possible to install a fiber laser cone right next to a plasma cutting head on a plasma cutting table, which wouldnÕt be an option for CO2 laser. Also, the ability to bend or coil fiber means that the systems […]
