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.

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.

Grip Force
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
