Ambulatory Data Loggers

UFI BioLogs™

BioLogs™ are rugged ambulatory physiological data recorders that support a broad range of signal conditioners including ECG/HR/IBI, EOG, EMG, EGG, EEG, respiration, PPG/PTT, pressure, temperature and more. Fetrodes™ are used on all bioelectric channels to reduce input noise at the source.

Three main platforms -- the 3991, 3992 and 3993 -- span needs for anywhere from one to 14 input channels. After signal conditioning tailored to your needs for gain, frequency response and sampling rate, each channel is digitized at resolutions that can range from 8 to 16 bits, then recorded to internal memory for later download. Battery operation (usually standard 9V) assures inherent subject isolation.

An Interface Box connects the BioLog to a USB port on the user's PC for data download, supervised by the UFI Downloading and Plotting Software (DPS). Once your data is written to the hard disk, the DPS can plot it onscreen, print it or move it to the Windows™ clipboard. Your data can also be converted into standard ASCII text files for further analysis with Excel or most any other data analysis package.

Model 3991 Hot Flash Monitor BioLogs

As a member of the UFI BioLog family, the standard Hot Flash Monitor is a one-channel unit with a signal conditioner designed to measure skin conductance, which generally rises rapidly with the onset of a menopausal hot flash. The unit pictured is available for sale now, see below.

FlashTrax Hot Flash Monitor

UFI is proud to announce the prototype FlashTrax System, the latest in our series of menopausal hot flash monitors. The very compact unit above is worn around the neck, hidden under clothing, and logs sternal skin conductance for up to 12 days. When the monitoring session concludes, the researcher downloads the subjective data for analysis and reporting with the research-proven FlashTrax software. Contact us for FlashTrax System availability.

UUB BioLogs

This new generation of tiny low-power BioLogs opens new research frontiers; one customer uses them to record ECG on condors soaring up to 15,000 feet. Another customer logged ECG on Weddell seals 2000 feet below the Antarctic ice. Birds equipped with the UUB BioLog may soon wing their way over the shoulder of Mount Everest.

As with our standard line of BioLogs, a wide range of signal conditioners is available as application-specific "daughterboards." Fingernail-sized microSD cards permit generous onboard data storage at minimal size and weight. Battery operation, usually with 3.6V lithium cells, gives inherent subject isolation while often allowing hundreds of recording hours between replacements. Data are downloaded and manipulated with the same Interface Box and PC software used by the standard BioLogs.
