Spring 2013 Bulletin

6/13/2013 1:10 PM

The Spring 2013 Bulletin focuses on the adaptability of Current Designs subject response systems. With the FIU-932 system the response pads and computer outputs can easily be customized when necessary.

Focus on: Custom Response Devices

Can't find what you need with the 24 standard response options available through our website? No worries!  Current Designs makes a wide range of custom response devices.  They all work with the FIU-932 or FIU-904 and standard fiber optic bundles and cables.

Our design process can help you get exactly what's needed. It's as easy as 1,2,3.

1.  Exact drawings are made from customer provided specifications.

2.  The dimensions are used to generate a 3D computer model of the device, which can be rotated and evaluated visually.

3.  The device's enclosure and fiber optic components are fabricated and assembled.

 

Types of Customization Available


   Moving or adding buttons to our standard enclosures.


   Using other enclosures that are larger or smaller.

   Fabricating an enclosure based on a researcher's specifications.  This involves some back and forth, but with our modeling and CNC tools it's an easy and cost-effective to get exactly what's needed for your subjects.

   Using a researcher supplied enclosure.  Often this is from an electrical device which is used in a non-fMRI setting.  Successful examples including the gamepad and footpedal show here.

Checking to make sure the drivers have installed -- IMPORTANT!!

If you are updating your 932 interface unit's firmware, using Arkeya for Windows, it is VERY IMPORTANT to first make sure that all drivers have downloaded correctly.

The best way to do this, is to connect your 932 interface unit to your computer using the USB cable and the Optical flashing cable and then, open up Arkeya. In the devices panel of Arkeya, the devices "932" and "932o" should appear. "932" represents the 932 interface's USB chip, while "932o" represents the 932 interface's optical chip. You will need to flash each chip with its own distinct firmware.

If you do not see both of these devices, then you SHOULD NOT continue with the firmware update.  You will need to reinstall the drivers.  If both devices do appear, then you can proceed to the "Updating the firmware" section of this page.

Reinstalling your Arkeya drivers

To reinstall your drivers, you will need to make sure you have one drive for each device installed.  First, find the "Filter Wizard" that downloaded and installed as part of the Arkeya package.  It can be found under the name "LibUSB-Win32", or simply instead search for "Filter Wizard".  Once this is open, choose "remove a filter".  In the window that opens, select all of the drivers that start with "vid:181b".  Then, go back to the first "Filter Wizard" window.  Now, connect the USB cable to your 932 interface unit.  In "Filter Wizard", select "install a filter".  Install the filter that should appear as follows:

vid:181b pid:0008 rev:0001 USB Composite Device

Now, disconnect the USB cable and connect the optical flashing cable.  In "Filter Wizard", select "install a filter".  The filter for this device should appear the same as before:

vid:181b pid:0009 USB Human Interface Device

You should now have both drivers installed for each chip.  Make sure to verify this by going through the steps found in "Checking to make sure the drivers have installed".  Once you are sure of this, you can continue on to updating your 932 interface's firmware.

Updating the firmware

Once you have made sure that the devices "932" and "932o" appear in the devices list of Arkeya, then you can proceed with updating your firmware.  If you have not made sure of this, please follow the steps found in the first section of this page!!

With Arkeya open, plug in your optical flashing cable.  Make sure that ONLY your optical flashing cable is plugged into the computer and interface unit.  The only device you should see listed is "932o".  

Select "932o" from the devices list and proceed to "Interface" on the menubar.  Select "Update firmware from local file".  Then, find the two files that were sent to you via email, that should now be saved somewhere on your computer.  The file you will need should be labeled rxxxo.hex, where the xxx should be some number.  The ending "o" indicates that it is the firmware for your optical chip.  Please make sure you select the correct file.  The update should take a few seconds.  Once this is complete you can update the USB chip.

With Arkeya open, plug in your USB cable.  Make sure that ONLY your USB cable is plugged into the computer and interface unit.  The only device you should see listed is "932".  

Select "932" from the devices list and proceed to "Interface" on the menubar.  Select "Update firmware from local file".  Then, find the two files that were sent to you via email, that should now be saved somewhere on your computer.  The file you will need should be labeled rxxxu.hex, where the xxx should be some number.  The ending "u" indicates that it is the firmware for your usb chip.  Please make sure you select the correct file.  The update should take a few seconds.

Your firmware update should now be complete.  If you run into any trouble please email support@curdes.com

Fall 2012 Bulletin

10/11/2012 4:58 PM

Focus on: FIU-932

Introduced in 2009, the FIU-932 (fORP Interface Unit) is the center of the light-based computer response systems developed at Current Designs.

More Optical Information

The 932 measures light inputs continuously, not only watching for light flux to cross thresholds, but rating the "health" of the attached devices by comparing insertion losses to values based on our accumulated records. This can help reduce downtime by warning users when it might be time to check their equipment, especially when the 932 is used in conjunction with Arkeya (our recently released diagnostic and configuration software).

Custom Cables

The MDR-36 connector provides legacy parallel and serial outputs but for many customers what makes it really shine is the capacity it provides for custom outputs, such as direct analog force signals and special synchronizing signals.

New Response Devices

The 932 interface has made better response devices possible including the redesigned trackball, joystick and five button response grip.


What's New: Pyka

Introducing Pyka, our newest response device. Finally, we have a great five-button response box. It's been designed to be easy to hold and easy to use.

Key Features:

1. Simple shape that's ergonomic to grip.
2. Cupped buttons to position finger tips.
3. Buttons springs are easy to push, for thumb to pinky responses.
4. Ambidextrous design for either hand.
5. Natural hand position for holding on or next to the thigh, or resting on the chest.
