3M 25-year light bulb requires unique die-cast components
When 3M began the design and development of its new 25-year LED light bulb, there were a number of aluminum components in the design that, in large volumes, would ultimately be too costly to allow for secondary machining and would require net-shape, high-pressure aluminum die casting. 3M's LED Advanced Light has a unique electronics-in-bulb design, sophisticated light-guide technology, and an estimated energy cost of $1.63 per year.

Advanced true-color, wide-view TFT LCDs
Kyocera Display America has added four TFT-LCDs to its extensive product line. The new 10.4-in. and 12.1-in. SVGA displays feature Advanced Wide Viewing (AWV) technology that enables people to view images with vivid color (no grey inversion) from any angle. One version of each display size also features super-high brightness for readability in sunlit or high-glare environments. Designed with the latest high-efficiency, long-lifetime LED backlights, the LCD panels provide an ideal solution for a range of applications, including medical, gaming, POS, ATM, and outdoor applications.

Friction positioning hinges provide constant torque for precise control
RT Series friction positioning hinges from Reell provide constant torque throughout their full 360-degree range of motion to precisely control and hold the angle of mounted components in any position. These hinges carry an industry-leading guaranteed service life exceeding 50,000 cycles. They integrate patented ReellTorq clip technology for a premium quality feel and smooth and precise position control without requiring adjustment during installation. Typical applications include motion and positioning of a display or access panel within a wide range of equipment and systems in the medical, aerospace and aviation, automotive, electronics, architectural lighting, and POP and POS industries. Three standard product families deliver successively more powerful torque capabilities.

Curvilinear motion system provides unlimited track shapes
1-Trak is a steel, single-piece, completely seamless guided motion system from Bishop-Wisecarver. Users can specify any shape with no joints. 1-Trak circuits can also accommodate much tighter bends than is possible with other systems. The design's natural strength and accuracy makes it suitable as a structural element of the machine. 1-Trak can be customized with holes, slots, and other features. Systems can be specified with a vee-profile guide section of any size to suit bearings from the extensive HepcoMotion PRT2 or Heavy Duty HDS2 ranges from 13 mm to 150 mm in diameter. Wheel plates can carry loads from 67 N to 51,000 N, and tracks can be made up to 5.5 m x 1 m or 1.9-m square. A rack-and-pinion driven wheel plate is another option.

Reduce wasted energy by 30 to 50 percent in air-handling applications
NovaTorque's family of Gen2.0 PremiumPlus+ electronically commutated permanent magnet (ECPM) motors uses low-cost ferrite magnets in an innovative flux-focusing design to deliver the superior efficiency of rare-earth permanent magnet motors at a price that is competitive with induction motors. And unlike induction motors, the PremiumPlus+ ECPM motors maintain their high efficiency and high torque over a very broad speed and load range. The motors boast motor-only rated point efficiencies of 93 and 92 percent for 3- and 5-hp versions respectively, far exceeding the levels achieved with induction motors. They are available in 3- and 5-hp 1,800 rpm models (maximum speed 2,700 rpm) and high-speed 3- and 5-hp 2,400 rpm models (maximum speed 3,600 rpm).

Military engineers teach an old water can new tricks
A system developed by researchers at the Natick Soldier Research, Development, and Engineering Center, Department of Defense Combat Feeding Directorate in Natick, MA, will help bring water to Soldiers in the field, either cool or heat it, and then keep it that way for days at a time. The system revolves around a high-stress collapsible water bag, a beverage cooling unit, and an insulated bag that holds the standard 5-gal water can or the collapsible water bag.
