Slip rings improve Ethernet transmission

The Kuebler Group offers contact and contactless slip rings for reliable Ethernet transmission, achieving higher data rates and greater cycle synchronicity in demanding industrial environments. Application examples include industrial automation, bottling plants, labeling machines, rotary tables, and other processes requiring high transmission rates. The standard Slip Ring SR120 features an innovative three-chamber system and shield to enable parallel, interference-free Ethernet transmission up to 100 Mbps. It boasts a long service life up to 500 million revolutions and a rugged, modular structure that can be expanded up to 20 channels. Another model, the Slip Ring SR160 with integrated Sendix Encoder, provides position information in addition to contactless Ethernet transmission -- either two channels at 100 Mbps multiplexed or one channel at 1 Gbps.

20-in. automotive touchscreens enabled by new controllers

With cars like the Tesla Model S featuring 17-in. touchscreens, the trend in automotive displays is to go bigger and bigger. But unlike handheld mobile devices, screens in automobiles need to meet stringent head impact and vibration tests, so they have thicker cover lenses that potentially affect the touch interface performance. As screens get larger, they are also more likely to interfere with other frequencies and car access systems. These factors pose a major challenge in the design of modern automotive capacitive touch systems, but a new family of single-chip maXTouch touchscreen controllers from Microchip Technology was designed to address these issues.

Electric high-force linear actuator choices: Ball vs. roller screw

Many applications require high-force linear actuators -- from moving equipment in a foundry to powering a press in metal forming to guiding heavy logs in a sawmill. Whatever the application, a machine designer is faced with a choice: whether to specify a ball or roller screw in the electric high-force linear actuator. Learn how to make the best decision for your application.

TRW outlines trends for automotive electronics growth in 2013

With continued pressure from legislators and consumer bodies to increase the fitment of active safety systems, leading auto manufacturer TRW Automotive Holdings Corp. expects several notable trends to develop in the electronics field including: crash avoidance technologies to become mainstream; focus on affordable radar and camera systems; and increased demand for open architecture systems.

Peter Lake, executive vice president, sales and business development for TRW, says: "Electronics is the fastest growing automotive commodity: industry estimators now place the percentage of a vehicle's cost attributed to this area to be as high as 40 to 50 percent, up from 20 percent a decade ago.

"Today, the industry is stepping up to the mark as organizations such as the World Health Organization and the European Commission have set ambitious targets to drastically reduce the number of road fatalities globally by 2020. To support this, New Car Assessment Programs (NCAPs), including Euro NCAP, are revising their rating programs to reward and promote safety improvements in new vehicles over the coming years. One of the most important goals of the new scheme will be to include emergency crash avoidance technologies, which will significantly boost the fitment of electronics content on new vehicles."

With Driver Assist Systems (DAS) set to become mainstream technology, TRW expects that optimizing costs will become an important topic for the vehicle manufacturer and supplier industry. In order to support the growing demand for video and radar, TRW is working with its customers to bring new, advanced safety technologies to market at an affordable price from the outset.

Dr. Hans-Gerd Krekels, engineering director, global integrated electronics added: "With a number of its safety systems including airbags and slip control systems -- TRW has a track record of designing and engineering affordable technologies. To achieve this, we need to think about the technological evolution of a product right from the start -- considering how technical advances and manufacturing process improvements can allow us to bring a product more affordably to market, but with the same performance.

TRW is seeing a clearer trend toward domain architectures and a greater demand for open system architectures in order to address the growing complexity of vehicle electronics. TRW is a leader in this area and will start production of its 'Safety Domain ECU' (SDE) this year with a major European vehicle manufacturer -- a technology that meets this requirement. "A significant aspect of our SDE is that is can integrate software from vehicle manufacturers or third parties. Without knowing the code, we can integrate the software in an "open architecture" system housed within the controller. These are in high demand as vehicle manufacturers are increasingly writing their own software and asking suppliers to manage the integration -- not just for active safety systems, but also for airbags, steering, and braking. This has grown enormously, and we expect to see exponential growth in this area," concluded Krekels. Source: TRW
