Green Bearings Curb Consumption
Bearing friction means lower efficiency and increased energy consumption. However, there is an effort to improve efficiency and reduce friction in ball bearings by up to 30%. This can provide big savings in many mechanical devices. The new bearings feature better internal geometry and polymer cages lubricated with low friction grease.

Bushings Bring Strain Relief
Stop stressing over the design of consumer electronic devices, power tools, appliances, and motor housings. This line of strain relief bushings for electrical wiring provides lasting protection against push, pull, or twist stresses on wires that could cause an electrical failure. The bushings require no special tools to install.

MEMs Gyro Sensors Test Torque
Shipping safe products to consumers means manufacturers must have a reliable method of checking critical fasteners for proper torque, but in many cases, human error can throw a wrench in the process. The good news is that a new gyroscopic torque sensor can weed out erroneous readings by capturing torque measurements based on fastener movement.

Stress-Free Splicing
Twist and crimp wire slicing may be the traditional method of terminating electrical wires. But an easier ergonomic solution for assemblers is available in the form of lever-actuated wire termination blocks. They are available in a variety of sizes with the two-wire model suited for use in power tools and electric motors.

Solar Power Polymers
As oil prices continue to rise, the push to find efficient solar power solutions is renewed. But unlike efforts of 30 years ago, product developers have a new arsenal of materials with which to work. While efficiency and cost are still the biggest issues, new flexible and printable polymer film materials promise better performance.

Material Manhole Makeover
The days of heavy cast iron manhole covers may be over with an engineered product that halves the weight of the long-lived standard. It uses an impact resistant ductile iron material. The manhole cover design includes better ergonomics with a twin hinge lift assist system and security features to prevent unauthorized access.

Heavy Duty Helping Hands
Working all day with heavy, high torque tools can result in repetitive motion injury or carpal tunnel syndrome. Heavy duty telescoping torque arms help abate assembly aches by absorbing much of the tool torque reaction. They also eliminate the need for operators to lift power tools into working position.

You want to be at your best when on the job, right? It's no mystery that sleep deprivation affects work performance. However, researchers now verify that getting less sleep does not just make you more "sleepy" and thus less active. Instead their study shows that a lack of sleep actually increases activity in the brain's center of emotion making participants more likely to lash out at others. So, besides being good at what you do, get enough sleep so that you get along with co-workers.

The Ebb and Flow of Computer Electrons
Researchers are investigating the possibility of a mechanical computer using nanoscale parts. Instead of using solid-state transistors and electronics to compute ones and zeroes, a nanomechanical computer would use moving parts — gates, and pillars and levers and pistons — to create switches, logic gates, and memory units, the building blocks of digital computers. The new mechanical computing devices would be work in extreme environments including space, car engines, battlefields, and children's toys, where silicon devices might fail.
