Merging Man and Machine - the Bionic Age

Porti

The Porti is a 32-channel ambulatory and stationary system for physiological research. The Porti is a multifunctional system and can have unipolar electrophysiological inputs (ExG), bipolar electrophysiological inputs (BIP) and auxiliary inputs (AUX) for measuring EEG, ECG, EMG, but also movement, position, respiration, etc.

The Porti includes TMSi's proprietary TAS2 (True Active Signal Shielding) technology for clean signals and data completely free of mains interference and cable movement artifacts. It does not include hardware filters (other than anti-aliasing) so the raw data is always available and quick recovery ensured. The ExG inputs are configured as a reference amplifier: all channels are amplified against the average of all connected inputs. The BIP inputs are used to measure two physiological signals differentially to each other. Using these ExG and BIP channels, signals like EEG, EMG, ECG, EOG, EGG etc. can be measured. The AUX inputs can be used for measuring sensor signals like temperature, pH, respiration, movement, force, angle etc. Each of these channels has a +5 V and -5 V supply in order to accommodate active sensors or sensor modules. For the measurement of oxygen saturation a special serial input is available. An isolated digital trigger input is also included.

The Porti system can be equipped having different number of input channels. Porti's with 16 and 32 channels are available.

The Porti can be used for both stationary as well as ambulatory measurements. In stationary setup an external power supply which plugs into the mains socket, powers the Porti. The Porti is connected to a PC by means of a bi-directional optical fiber. It is also possible to use a built-in Bluetooth telemetry module to send the data directly to a PC. Please note that the bandwidth may be limited when using the telemetry option. When the Porti is used in ambulatory mode, it is always powered by batteries.
