This paper presents two test systems, the first with Agilent equipments and the second with National Instruments equipments. A comparison will be made about the characteristics of each. In each test systems will be presented the three main equipments which are compulsory for a functional test system: power supply, multimeter and function generator.
The formulation of a grid point shallow-water model proposed by C^ ot e and Stan-iforth is described. The model employs a hybrid nite-volume//nite-element spatial discretisation on a staggered Arakawa B type grid, where the geopoten-tial is computed at grid points and the wind u is found at grid cell centers. Time integration is based upon a two-time-level(More)
In this paper more temperature measuring techniques will be presented. Our focus is on the technique, how to get the temperature information from the sensor to the PC, not the software it's self. Four temperature sensors will be presented, each of them different, needing different kind of mathematic calculation to obtain the temperature. To know these(More)
This paper presents the automatic control of a temperature chamber. The temperature chambers are used to simulate temperatures from freezing temperatures to very high temperatures. These temperature chambers are often used for testing circuit board in the automotive industry, because this industry requires a big temperature interval. It will be presented(More)
This paper presents two methods to recognize colors with a simple webcam. The first application is made in Lab VIEW v8.6 with NI Vision Development Module v8.6 and NI IMAQ for USB. The second application is made in LabWindows/CVI with an external library for vision. The interesting fact about the first application is that LabVIEW supports only expensive(More)
This paper presents a clock built around the MC9S12XDP512 microcontroller using an LCD display. This clock shows the time (hours, minutes, and seconds) and the date (year, month, day). The MC9S12XDP512 development board from Freescale has no integrated LCD module, so an external module had to be connected. The date is fully displayed (four digit years) and(More)
