Lubrication Considerations for Bearings

Bearings must be properly lubricated for optimized performance and long service lives, so choosing the correct lubrication is an integral consideration for engineers. AST Bearings’ tribological team has created this comprehensive whitepaper to best explain these lubrication considerations in rolling element bearings. The paper examines types of bearing lubricants (oil, grease and solid film), bearing lubrication methods, bearing lubrication shelf life, and a detailed table showing common bearing lubricants and properties.

Will virtual traffic lights improve traffic?

This week's Question: Carnegie Mellon University researchers have claimed that they can reduce commute times by placing virtual traffic lights on drivers' windshield. Through connected vehicle technology, the Carnegie Mellon system replaces conventional traffic lights with stop and go signals appearing directly in view. The virtual traffic lights are generated on demand when needed, such as when two cars are approaching an intersection. Read more »

The Human Eye Can See ‘Invisible’ Infrared Light

Any science textbook will tell you that human beings can’t see infrared light. Like X-rays and radio waves, infrared light waves are outside the visual spectrum. But an international team of researchers co-led by scientists at Washington University School of Medicine in St. Louis has found that under certain conditions, the retina can, in fact, sense infrared light after all.

Scientists Slow the Speed of Light Travelling Through Air

Scientists have long known that the speed of light can be slowed slightly as it travels through materials such as water or glass. However, it has generally been thought impossible for particles of light, known as photons, to be slowed as they travel through free space, unimpeded by interactions with any materials. Researchers from the University of Glasgow and Heriot- Watt University, however, recently described how they have managed to slow photons in free space for the first time. Read more »

Single-Chip Optical Encoders

iC-Haus (Bodenheim, Germany) has developed sensor chips for optical position encoders using photodiodes designed especially for blue light. The new iC-PT H-Series chips combine optimized scanning and signal interpolation in a flat 5 x 5 mm² optoQFN package with a plane window. Due to the optimized Phased- Array structure of the opto-chips, a minimal scanning area of only 1.9 mm x 3.1 mm is sufficient to generate 10,000 pulses per revolution using a code disc of only 26 mm diameter, for example. The blue light LEDs increase contrast with lower noise. Read more »

High Output LED Downlights

Hubbell Lighting (Greenville, SC) now offers Prescolite’s MegaLum high output LED downlight in lumen packages ranging up to more than 16,000 lumens. Available in either a downlight (MD8LED) or cylinder (MC10LED) option, the MegaLum is capable of delivering over 16,000 lumens and up to 100 LPW and offers a variety of dimming options including DMX. With a rated minimum of 50,000 hours life, the MegaLum ensures lasting maintenance-free operation. Read more »

Five-Watt LED G9 Lamp

MaxLite (West Caldwell, NJ) has introduced an energy-efficient replacement for 40-watt halogen T4 G9-based lamps. The five-watt LED retrofits easily into existing G9 sockets in decorative glass pendants, chandeliers and bath bars. Available in dimmable and non-dimmable versions, the lamp delivers up to 450 lumens with a 300-degree beam angle for uniform light distribution. Read more »

LED Lights with Symbol Marking

Wilbrecht LEDCO (St. Paul, MN) has added symbol/legend marking options to its 100/600 series of panel LEDs for custom applications. Custom and universal symbols, such as battery light or oil level, can be used for easy identification. A simple stamp printing process allows a pictogram or short word to be printed in white or black ink on blue, green, amber, red and clear lenses. The LEDs can be selected in 3 intensities- High Efficiency, Daylight readable super bright, and super ultra-bright. Read more »

Profit Margin Increases With Farm Size

Given the broad USDA definition of a farm, most U.S. farms are not profitable as ongoing businesses. One commonly used measure of profitability is the farm’s operating profit margin (OPM), the ratio of operating profit to gross farm income.

Prices Play Greater Role Than Access in Food-Purchase Decisions for SNAP Households

Lack of access to large grocery stores and other sources of healthy food options has been thought to be linked to obesity and other diet-related diseases. ERS researchers, however, found that food prices have more effect than food store access on purchase decisions by participants in USDA’s Supplemental Nutrition Assistance Program (SNAP).
