Planetary gearhead offers a range of ratios for speed reduction or torque multiplication in a 13-mm diameter package. The gearhead is available as a metal version for higher load capability or as a plastic version for reduced cost and weight, which varies from 0.2 to 0.8 oz. Length varies from 0.61 to 1.28 inches depending on which of the five different ratios are used, with a maximum efficiency of 91%. Maximum continuous torque is up to 49.5 oz-inches and 75 oz-inches on an intermittent basis. Maximum axial load is 1.8 lbs, and operating temperature range is -15 to 65C.

Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
