java drivers for data acquisition hardware?

I need to do some data acquisition & would like to use Java to program my data acquisition application. Right now I am using a LabJack which has a Java wrapper for its driver & it's working ok for simple stuff but I need to upgrade to something real. anyone aware of a data acquisition platform (NI or Measurement Computing or one of the ...

Database design for data acquisition with multiple variable types

I'll design and implement database for data acquisition and started to wonder what might be the best relational database structure for multivariable solution. There can be dozens of variables (configurable), different types (boolean, integer, float at least, maybe string). Values of different variables are not related. I need to store va...

Atalasoft DotImage Licensing...

Hi, I have been trying to find decent Image Acquisition + Image Processing solution at a bargain price. I have looked at names like Kodak, Global360, Iris. What I found with all these vendors is that they are very, very, very expensive. I have also found that the SDK API licenses are just as expensive, if not more. Please see Atalas...

Control DAQ Board Digital Outputs with A Matlab GUI

Hi, i m new here and i m looking for help, i tried averywhere on the net but i m still confused. so here is my problem, My DAQ board KPCI-3103A ist connected to another Board where an Ultrasonic Sensor (Dual-Use:sender/reciever in one) is Brazed. I must send Digital Signals in Loop from my KPCI-3103A to the Sensor-Board to control the S...

Using both a message queue and database.

I will be developing a system that will involve a data acquisition server where each acquisition will fill a row. I also need to have the ability to inform the user application of when new data has been acquired. From what I have read, it's not a good idea to use a database as a message queue and vice versa, but I was wondering if I co...

MEX-File to Output Pulse in a Loop to a DAQ-Board

Hi there, i figured I must use a MEX-File to output Digital pulses in a loop (40 kHz) from Matlab to my DAQ-Board, I have some APIs from the DAQ-Board vendor, but I really dont know if they are useful. It´s a big documentation on the Mathworks website about MEX-File and APIs, that just make me confused. So I´m asking here if someone ca...

Labview + National Instruments hardware or ???

I'm in the processes of buying a new data acquisition system for my company to use for various projects. At first, it's primary purpose will be to monitor up to 20 thermocouples and control the temperature of a composites oven. However, I also plan on using it to monitor accelerometers, strain gauges, and to act as a signal generator. ...

Data Acquisition Toolbox for Matlab?

Has anyone here used the Matlab Data Acquisition Toolbox before? I've been spending a ton of time reading up on National Instruments products and their capabilities when used with Labview. However, Labview and NI hardware is pretty much the only thing I've looked at and I'm curious as to what is out there that competes with labview i...

other problems with data acquisition from MATLAB

3 days ago I asked for help in acquiring data from a text file generated by a C program (. Exe). Thanks to the programmer "second" I solved the problem but yesterday I discovered that the output file is more complex than I had expected. I also ask you help. The file output is: V|0|0|0|t|0|1|1|4|11|T4|H13|||||||||||| P|40|0.01...
