A microcomputer-controlled complex reaction time instrument

A microcomputer- controlled thermostat

Introduction Careful temperature control is essential for a wide variety of chemical measurements. High-precision potentiometry, for instance, requires thermostatting, since the slope of the straight line E vs log a is highly temperature dependent (E is the measured emf, log a is the logarithm of the activity of species i). The equation describing the relationship between the measured quantity ...

The design of a microcomputer-controlled voice onset time analyzer.

In spoken syllables such as "ta," the interval between the release of the tongue constriction for the stop consonant /t/ and the onset of the vowel is called voice onset time, or VOT. Voice onset time is an important determinant of whether the initial consonant will be heard as a /t/(values of 60-90 ms) or as a /d/ (values of 0-30 ms). VOT information, immediately following a spoken syllable, c...

Stable, Low Cost Microcomputer Digital-To-Analog Instrument Control*

Two methods of computer-controlling an electronic instrument are described. One method employs a computer having as few as two digital-to-analog converters. A second method is shown which can be used if a 16line digital output is available. Features of either method include low cost, high accuracy and stability, low noise and ease of installation. (Submitted to Review of Scientific Instruments)...

Microcomputer-controlled Devices for Human Implantation

Microcomputers, microsensors, micropumps, micropower sources, and micromedication dispenssers, in the form of programmable systems, are being developed for implantation in humans. An implantable insulin pump system for the control of diabetes has been developed. An extension of this technique is discussed in the form of a microcomputer-controlled closed-loop system by which medication is dispen...
