Chicago, Ill.—The semi-annual Sensors Expo—sharing the Rosemont Convention Center with the International Robots & Vision Show and Finishing 2001—featured cool chips and connectivity here on June 5-7. National Instruments (Austin, Tex.) unveiled its Order Analysis Toolset for LabView, which adds sound and vibration analysis capabilities, and its latest Imaq vision software, which delivers tools to complement Visual Basic, Visual C++, and ANSI C languages. Iotech (Cleveland, O.) showed its distributed I/O modules for low I/O count nodes that include an Ethernet-to-RS-485 gateway. Cygnal Integrated Products (Austin, Tex.) introduced its C8051F206 integrated, in-system programmable, mixed-signal system-on-chip microcontroller, which allows designers to convert ordinary sensors into compact smart sensors. Accurate, low-power (3 V) analog-to-digital converters (ADCs) from Cirrus Logic (Austin, Tex.) allow instruments that normally require ac power to run on batteries without sacrificing performance. Endevco (San Juan Capistrano, Calif.) exhibited Model 515 and 518 low-cost piezoelectric accelerometers offered in TO-5 and TO-8 packaging; Model 52M1/M2 Isotron accelerometers with high-output sensitivity, signal-to-noise ratio, wide bandwidth, and hermetic construction; and Model 63C12/63C13 triaxial i-TEDS piezoelectric accelerometer, which incorporates an IEEE 1451.4-compliant, built-in digital memory chip.
