Here are my thoughts on the ninth week's material, etc.

• This segment uses LabVIEW to control instruments.
• General introduction to computer-based measurements.
• Get over the disappointment of instruments sending back character strings.
• Builds a base for next week's work on manipulation of data in different forms - string, floating point, integer, etc.
• Raises issues about timing of loops in order to control timing of measurements.
• Lab this week consists of taking two types of measurements voltage and temperature.
• I'm not sure that taking voltage measurements and temperature measurements are really contrasting cases (as Bransford discusses in "A Time for Telling".), but it might be good next time to elaborate on this and expand to measuring resistance and frequency.
• The focus of this lab is to be able to explain what takes place when a measurement is taken.  There are a lot of steps that have to be implemented just for a single measurement, and each step requires integrating computer code (in the form of one of LabVIEW's icons) and an understanding of what is taking place in the instrument and the computer.
• These measurements are single measurements.  Next week we put this code into a loop and store data in a file.
• In-Class exercises
• Class Notes - Good
• Some things to think about.
• Not much here
• Sensors encountered to this point in the course.
• Thermocouples
• LM35s - giving two examples of sensors with voltage outputs
• Thermistor - giving an example of a sensor with a resistance change.
• AC Tachometers
• Pressure Sensors
• Strain Gages
• Light Sensors (Photovoltaic cells)
