Biopac Student Lab (BSL) System

The Biopac Student Lab system is manufactured by BIOPAC Systems, Inc., California. Students in biomedical teaching labs use the BSL system to record data from their own bodies, animals or tissue preparations. The BSL system integrates hardware, software and curriculum materials including over sixty experiments that students use to study the cardiovascular system, muscles, pulmonary function, autonomic nervous system, and the brain.

The BSL system includes data acquisition hardware with built-in universal amplifiers to record and condition electrical signals from the heart, muscle, nerve, brain, eye, respiratory system, and tissue preparations . The data acquisition system receives the signals from electrodes and transducers. The electrical signals are extremely small—with amplitudes sometimes in the microVolt (1/1,000,000 of a volt) range—so the hardware amplifies these signals, filters out unwanted electrical noise or interfering signals, and converts them to a set of numbers that the computer can read. Biopac Student Lab software then displays the numbers as waveforms on the monitor.

The data acquisition system connects to a PC running Windows or Macintosh operating systems, via USB. The electrodes and transducers employ sensors that allow the software to communicate with the students to ensure that they are using the correct devices and collecting good data. Software guides students by using onscreen instructions and a detailed lab manual follows the scientific method. Once students have collected data, they use analysis tools to measure the amplitude and frequency, plus a wide range of other values from the electrical signals . The analysis process allows students to make general comparisons with the data. They can compare their results to published normal values, or the values before and after a subject performed a specified task. They can also compare results with other students in the lab. The software is available in English, French Spanish, Italian, Japanese, and Chinese.

Thousands of undergraduate labs worldwide use the Biopac Student Lab System to teach physiology, pharmacology, biology, neuroscience, psychology, psychophysiology, exercise physiology, and biomedical engineering.

BSL BIOENGINEERING SYSTEM

The BSL Biomedical Engineering System provides extensive recording and analysis options for signal processing curriculum, including bioelectric and biomechanical studies. The data acquisition unit includes four universal, software-programmable amplifiers that can record biopotential and transducer signals. The BSL hardware/software combination creates a virtual instrument that can be tailored for a wide range of measurements with analysis tools for digital filtering, integration, differentiation, FFT, convolution, correlation, and a host of signal processing options. The Breadboard allows students to build and test real circuits and then use the software to compare real results to simulation. Collect, display and investigate data with the BSL System, or use it to direct data to industry-standard applications like MatLab or LabVIEW.
