Introducing UFI BioLogs™
We can offer many flexible ambulatory recording platforms to fit your subject and their environment, your research requirements and protocol, and your budget.
These 3991/3 ThA BioLogs™ record two channels of internal temperature data and one channel of ambient temperature. Paul Ponganis, M.D., Ph.D. (Scripps Institute of Oceanography, University of California at San Diego) used these BioLogs to study body temperatures in diving Emperor Penguins in Antarctica. Dr. Ponganis has been using a variety of our BioLogs for over a decade now. Typical output is shown below.
An Overview of UFI BioLogs
The BioLog is a rugged, yet flexible, ambulatory physiological data recorder that supports a broad line of signal conditioners and research scenarios.
For human subject use, we currently offer three easily customized platforms; the 3991, 3992 and 3993 Biologs are available to fit many human research protocols and requirements.
For Hot Flash research, we can also supply a number of Biolog based systems, centered around our the 3991-SCL series, that are specially designed for menopausal hot flash monitoring research.
For more demanding animal, aquatic or avian research, we can offer our smaller UUB series recorders. Developed since 2008, this system has proved very popular with resarchers who require very small, low-power physiological data loggers.
Conditioned data are sampled by all Biologs at the desired resolution (generally 12 bits) under microprocessor control. Recorded data are compactly stored in internal 'Flash' memory. When recording is complete, a BioLog Interface Box connects the BioLog to a USB port on the user's PC for data download.
UFI Downloading and Plotting Software (DPS) running on the host PC supervises data download a hard disk file. From there it can be viewed, printed, moved to the clipboard, or converted into ASCII data files for further analysis with Excel and many other data analysis packages.
Numerous other researchers have been satisfied users of UFI BioLogs; John W. Denver, Ph.D., then Research Assistant Professor at the Brain-Body Center, Dept. of Psychiatry, University of Illinois at Chicago has been kind enough to offer a testimonial.
Features common to all BioLogs
- A wide range of signal conditioners are available
- Available sensor inputs include ECG/HR/IBI, EOG, EMG, EGG, EEG, respiration, PPG/PTT, pressure, temperature and more
- UFI proprietary front-ends (input sensors) include Skin Conductance Level (SCL) and Impedance Respiration
- Each input signal conditioner is designed to your specifications for gain, frequency response, sample rate, etc.
- Fetrodes™ are generally used on all bioelectric channels to reduce input noise at the source
- Rugged keyed and locking input connectors are often standard
- Battery operation (usually 9V alkaline) gives inherent subject isolation
- Flash memory gives flexible amounts of data storage
- Data are downloaded to your PC computer through a UFI interface box (see below)

BioLog Downloading and Plotting (DPS) Software
UFI Downloading and Plotting Software (DPS) running on the host PC supervises data download to a hard disk file. From there it can be viewed, printed, moved to the clipboard, or converted into ASCII data files for further analysis with Excel and many other data analysis packages.
DPS functions
- Supervises data downloading from the BioLog to a file on the hard disk of your PC
- Allows easy display and review of recorded, downloaded data
- Permits printing of displayed data or transfer to clipboard
- Converts data to channel-specific ASCII data files for further analysis in user's choice of software
- DPS recorded data based scanning and post-processing options are also available
- DPS Price is per site and includes software and interface box
- Each DPS is custom configured for your BioLog
Model 3991BIB Interface Box
The Interface Box mediates between the PC running the DPS software and the BioLog. The box connects the BioLog to the host PC through one of the PC's USB ports with a standard USB cable. The Interface Box connects to the BioLog through the "Link" Cable.
Interface Box functions and features
- transfers start-up information from the DPS software to the Biolog during BioLog initialization (some Biologs)
- permits data collected with the BioLog to be downloaded to your computer with the DPS software
- minimizes current drawn from the onboard BioLog battery while the BioLog is connected to the PC
- front-panel Function Switch controls power to the Interface Box itself as well as power to the BioLog during the deployment process
- the Function Switch also controls the USB connection between the BioLog and the host PC
- some Interface Box models, as pictured above, are supplied with a Function Switch "Test" position and LED that permits BioLog recording activity to be verified after recording has started
- the (optional) front-panel LCD shows the voltage supplied from the Interface Box to the BioLog. If the Function Switch has a "Test" position, the LCD also displays the onboard BioLog battery voltage, so you can check this before releasing your subject.
- power for the Interface Box is supplied by the USB connection to the PC computer. (9V battery and Wall-Mount Transformer power options are also available.)
- rugged ABS plastic case is 7" x 5" x 2.5" (178mm x 127mm x 64mm)
