MR-Compatible Response Devices
Current Designs 932 Interface
The opto-electronic interface receives optical signals from the handheld devices in the MR suite, and converts them into electronic signals for the computer.
- A bright OLED display guides the user through available mode choices - simplifies setup
- Automatic handheld device identification - speeds up setup
- Optical triggering - no need to have an optical-TTL converter
- Faster everything - better timing, improved responsiveness
- 32 channels with automatic gain adjustment and response device identification
- Button states and triggers are indicated with LEDs (for up to 10 buttons)
- The primary output for most users is the full speed USB output which simplifies interfacing to any hardware or program
- The multi-function MDR connector provides RS-232 serial and TTL parallel outputs and is also available for special interfacing needs including support of older programs and computers.
2 Button Blue Yellow Button Box
Current Designs' fMRI response pad is the perfect choice for computer response tasks used in the human brain mapping project. It is non-magnetic, non-electronic, and entirely made out of plastic, so will not add noise to the images or raise safety concerns in the MR/MEG room or similarly demanding environments.
Five Button Fiber Optic Response Pad for computer research tasks in fMRI.
Joystick Fiber Optic Response Pad for computer research tasks in fMRI.
- Two axis shaft encoder control
- Angular range: 30 degrees (+/-15 degrees).
- A wide variety of serial and USB outputs are available for Windows, Mac and Linux computers for high speed and demanding applications
- Two 1 in. (2.5 cm) long levers on grip for thumb and trigger buttons.
Trackball Fiber Optic Response Pad for computer research tasks in fMRI.
- Two axis encoder control
- Two (2) side buttons
- Special calibration mode for the trackball
Force Fiber Optic Response Pad used in fMRI.
- Machined black enclosure with protruding force bar which moves in when gripped to produce a roughly linear force measurement output based on the pressure applied, with a range of 25N, 50N, 75N, 100N, 300N, or 500N (specified at time of order)
- Wide variety of outputs available for Windows, Mac and Linux computers, including several USB and Serial modes
- Active light levels for handheld identification and gain adjustment
