Researchers create artificial eye chip for robots
News & Analysis  
3/30/1999   Post a comment
Harnessing neural-network technology gleaned from the biology of the human eye, a Johns Hopkins University researcher has demonstrated a "smart eye" chip that combines image sensing with filtering and object-tracking capabilities. The brainchild of Ralph Etienne-Cummings, the circuit is based on a hybrid analog-digital CMOS technology and is touted as being much faster than distributed-component systems that use separate chips — such as an image sensor, microcontroller and non-volatile RAM
Neural nets create natural speech interaction
News & Analysis  
3/15/1999   Post a comment
SpeechWorks International is applying neural-network technology in a practical-speech-recognition system that achieves a new level of natural-speech interaction by letting telephone callers ask for information in ordinary, unstructured English. Federal Express Inc. is delploying the approach in a shipping-rate information system in cooperation with NextLink Interactive.
Molecular switching is probed for nanocomputers
News & Analysis  
3/15/1999   Post a comment
As chemists learn more about molecular behavior, the possibility of building nanocomputers-both CPUs and memory systems-is getting closer to reality. Both the complex proteins manufactured by virtually all living systems and long chain polymer molecules can act as bistable devices when their basic 3-D configurations change as a result of outside stimulation. Probing with tiny atomic-force microscope tips or simply using photons, researchers are getting a handle on molecular mechanisms that could
Neural net mines database for rules
News & Analysis  
3/8/1999   Post a comment
Engineers at SciFi Ltd. (Woburn Sand, England) have come up with a way to automate the process of extracting meaningful information from massive technical databases, automating a process that can be labor-intensive and time-consuming. RuleMiner finds fuzzy rules implicit within existing databases and codifies them for use by another program that interfaces with real-time control systems.

IoT Network Shoot Out
July 16, 1pm EDT Thursday

Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion. Join in and ask his guests questions.
