ifm efector Diode Array Technology -- Using a diode array integrally mounted on an ASIC, the OJ sensor's convergent-beam technology precisely allows both small-object detection and background supression at long ranges using a high-pwer LED or laser. Previoulsy, single-diode background-supression sensors were good at essentially only one range (i.e., only one triangulation geometry) for the object and background unless mechanically adjusted, which required valuable time.
Precision position sensors traditionally have had to be placed closed to the objects they are to detect (usually 20-40 mm, with 100 mm the maximum)—putting them in harms way of impact with machinery or human operators. And those devices, even if able to detect from a reasonable distance, are often too large to fit in confined spaces around production machinery.
Now, thanks to patented diode-array technology, a small (24 x 45 x11 mm) sensor can sense from 15 to 400 mm because of a more powerful LED light source, or from 7 to 150 mm with a laser. Spot size diameter with the LED is 18 mm and the laser's 0.8-mm spot allows distance sensing below 0.5 mm. A 63-diode array is mounted on an ASIC for detection and processing in a single, integrated component. The array allows sensing at various distances because it can accommodate different target and background triangulation geometries without any mechanical adjustments. The OJ sensors come in front or side sensing body geometries. According to the company, cost is comparable to previous technology devices with less capability.
Applications for the sensor include error proofing as well as part detection. Users of the more precise laser variant of the OJ Series background suppression sensor are employing it to verify assembly integrity, such as correct seating of an o-ring, bolt tightness, or part press fit. A variety of fixed mounting brackets allows snap-in replacement without tools, eliminating realignment for fast production-line turnaround.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
