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.

New touchless angle sensors with CANBus interface

Novotechnik, U.S. introduces the RFC4800 Series of touchless angle sensors measuring angular position up to 360°, revolution counter, and speed -- with J1939 CANBus interface in addition to CANopen. Features include programmable zero-point offset, measurement averaging, and sign of rotational direction. RFC4800 Series has a resolution of 14-bits across 360°, repeatability of 0.36°, and independent linearity of +/-0.5% of full scale. J1939 CANBus provides a different feature set than CANopen. It has peer-to-peer or broadcast signaling and fixed messages rather than configurable. There are other differences too.

Minimizing noise in electric linear motion systems

Under most circumstances, electric linear motion systems are quiet. They certainly don’t create the hissing and bang-bang noises associated with pneumatic systems. However, there’s another type of noise that comes with electric systems of all types: electrical noise or interference. The results can be anything from erratic movements to complete system failure. Patrick Hobart from Tolomatic runs through best practices for minimizing noise in these automation systems.

Battery-free 'smart' toys move closer to commercial reality

Rubber duckies could soon be at the forefront of an electronic revolution. In ACS Sustainable Chemistry & Engineering, scientists report they have used specialized nanogenerators that gather energy from mechanical vibrations to transform squeaky bathtub companions and other conventional children's toys into "smart" electronics. They say the finding could have broad commercial applications, leading to the development of battery-free, self-powered toys, medical sensors, and other devices.

By age 4, virtually every child has had contact with an electronic toy or mobile device, according to the American Academy of Pediatrics. Keeping these devices blinking and beeping is tedious, often requiring frequent charging or battery changes. Researchers have explored alternative ways to produce and store energy for these devices without using batteries.

One promising approach involves the use of triboelectric nanogenerators, or TENGs. TENGs gather electrical charges from friction, similar to the static that builds up on a balloon when it is rubbed against someone's head. TENGs amplify and convert this biomechanical energy into a usable form. However, ramping up these devices for commercial applications has been challenging, possibly because of low energy storage and conversion efficiencies.

To address some of these issues, Sang-Jae Kim and colleagues at Jeju National University in South Korea sought to harness the energy from TENGs more effectively and use it to transform traditional toys into commercially viable, self-powered toys.


VIDEO: Rubber duckies could soon be at the forefront of an electronic revolution. In a study appearing in ACS Sustainable Chemistry & Engineering, scientists report using specialized nanogenerators that gather energy from vibrations to transform the squeaky bathtub companions and other children's toys into smart electronics.

The researchers designed and incorporated TENGs -- made with aluminum electrodes and an eco-friendly silicone-like film between them -- into rubber ducks and clapping toys. Squeezing or shaking the toys alternatively separated and brought the electrodes into contact with the film, creating an electrical charge. Once activated, the TENGs harvested enough biomechanical energy to illuminate several LED lights attached to each toy.

The TENGs were durable, suggesting they could operate for substantial periods. The researchers conclude their unique approach can transform some traditional toys into battery-free interactive ones, and raises the prospect of successfully using TENGs commercially in other gadgets, including medical devices and wearable electronics.

The abstract that accompanies this study is available here.
