Cool Tools: Minimally invasive video borescope

Extech Instruments has launched the BR250-4, an affordable and versatile wireless inspection borescope designed to get into openings as small as 4.5 mm while providing bright clear images on its detachable, wireless 3.5-in. color display. When you need to get into walls, ducts, furnaces, boiler tubes, air handlers, exchangers, coils, plenums, and other concealed or hard-to-access areas, this is your hero. And when there's no existing opening and drilling is required, making a much smaller hole leaves minimal damage.

Application Note: Cooling for automotive applications

Advances in automotive technologies such as smart headlights, autonomous systems for collision avoidance, and infotainment systems require enhanced thermal protection of critical electronics to ensure optimized performance. Packing more functionality into smaller footprints has increased the heat flux density and thermal challenges in automotive electronics. Designing active cooling systems will provide a thermal management solution needed to operate each sensitive device within its temperature range and optimize its performance.

Collect and understand vibration condition data

Vibration monitoring is one of the most effective ways to detect potential equipment failures before they cause downtime. However, vibration analysis is complex, and it can be cost prohibitive to place sensors on noncritical assets. The new, wireless Fluke 3561 FC Vibration Sensor allows maintenance teams to improve uptime by adding remote, continuous vibration monitoring to virtually any rotating equipment. With a frequency range of 10 to 1,000 hertz, the 3561 FC detects and notifies users of conditional changes caused by critical faults like imbalance, misalignment, looseness, and bearing wear, providing warning of impending equipment failure.

LED headlights installed on San Francisco's historic cable cars

Since 1873, the best lighting the historic San Francisco Municipal Cable Cars had was dim incandescent headlights that did not do anything for illumination. They were merely bright enough to serve as an indicator that a cable car was coming. After over 140 years, that finally changed with their upgrade to LED light bulbs from LEDtronics. Along with the PAR46 LED headlights, A19-style LED light bulbs were also installed inside the passenger cabins. Savings on energy costs and maintenance are major benefits.

Verify color accuracy in real time

The LEX-1000 sensor from EMX Industries is used to measure the relative color characteristics for a wide variety of light sources and illuminated objects. It focuses the light onto a sensitive RGB photodiode, where it is measured for its red, green, and blue (RGB) composition. When all three colors fall within the programmed tolerance, the output indicates a match. This is a great solution for evaluation of all visible light sources, LCD and LED display quality, and automotive lighting verification.

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
