These puppies do more than just sit there and look cute. Sensing a human presence, the interactive, battery-powered toys react with actions and sounds. Motion includes head tilting and movement from side to side. The unit makes several sounds include whimpering, happy panting, soft whines, snoring, playful growling, playful barking and a waking-up noise. Touching the pooch’s nose instigates a low growl. Analog functions include the amplification for the sounds, actuating the motors and motion and touch sensing. Converting the motion sensor’s signal to an input for the microcontroller requires analog circuitry for threshold detection.
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.
