ML317 EOG Pod

ML317 EOG Pod

ApplicationsThe EOG Pod is used to measure and display eye movement and position.In the human the EOG Pod can be used in the measurement of saccadicand pursuit eye movements. It is ideal for use in undergraduate teachinglaboratories.

The ML317 EOG Pod is a signal conditioner designed to record horizontaland vertical eye position and movement. The device features a manual DCoffset and is supplied with three shielded lead wires with snap-onconnectors.

System CompatibilityThe EOG Pod connects to any PowerLab hardware units with Pod ports (8-pin DIN inputs). PowerLab and MacLab (except 4s, 8s and 16s) unitswithout Pod ports require the ML305 Pod Expander.

The EOG Pod is supported by the following versions of Chart and Scopesoftware:

WINDOWS MACINTOSH

• Chart v3.4.8 or later • Chart v3.6.3 or later

• Scope v3.6.3 or later • Scope v3.6.3 or laterNote: Earlier software versions do not support Pods.

Theory of OperationThe EOG Pod is a DC coupled biopotential amplifier with a fixed low-passfilter (500 Hz) to remove high frequencies. On the front of the Pod, anoffset knob is provided to remove DC drift. The offset control provides ±15mV of offset range (at input) for all range selections.

The EOG Pod utilizes the steady corneal-retinal potential in the detectionof eye movement and position. This steady dipole may be used tomeasure eye position by placing surface electrodes to the left and right ofthe eyes (Figure 2). When the gaze is straight ahead, the steady dipole issymmetrically placed between the two electrodes, and the EOG output isapproximately zero. When the gaze is shifted to the left, the positivecornea comes closer to the left electrode, which becomes more positive.There is an almost linear relationship between horizontal angle of gazeand EOG output (approximately ±30º of arc). Electrodes can also be placedabove and below the eye to record vertical eye movements and using twoEOG Pods, simultaneous vertical and horizontal eye movements can bemeasured (Figure 3).

Stacking and Unstacking PodsPods stack by clicking into place on top of each other. To separate stackedPods, push the top Pod towards the back and then pull them apart fromthe back. See picture on right.

ML311 Spirometer Pod

ML311 Spirometer Pod

ApplicationsThe Spirometer Pod is suitable for differential pressure measurements ofdry non-corrosive gases such as air flow and pulmonary functionmeasurements.

A compact respiratory signal conditioner for use with PowerLab dataacquisition systems. The Spirometer Pod is a differential pressuretransducer with low noise and low air flow resolution, which interfaceswith respiratory flow heads to measure air flow rates for humans andanimals. When used with ADInstruments respiratory flow heads and theSpirometry Chart Extension (software), compensated volume and forcedrespiratory parameters can also be determined.

Transducer CapabilityThe Spirometer Pod is suitable for operation with ADInstrumentsrespiratory flow heads including MLT1L, MLT10L, MLT300L and MLT1000L,see page 159 for more details.

Hans Rudolph flow heads are also compatible with the Spirometer Pod.

System CompatibilityThe Spirometer Pod connects to any PowerLab hardware units with Podports (8-pin DIN inputs). PowerLab and MacLab (except 4s, 8s and 16s)units without Pod ports can connect to Pods by using the ML305 PodExpander.

The Spirometer Pod is supported by the following versions of Chart andScope software:



Theory of OperationAir flowing through a wire mesh in the respiratory flow head creates apressure difference on either side of the mesh. A larger airflow creates agreater difference. This pressure difference is transmitted to theSpirometer Pod via two tubes and converted to an analog voltageproportional to the air flow rate. The Spirometer Pod also provides low-pass filtering fixed at 30 Hz.


Caution - The Spirometer Pod’s differential pressure sensor is position andmovement sensitive. For consistent recordings always keep the Pod in thesame orientation. Keep the Spirometer Pod on a stable surface whilerecording. Any movement will result in unwanted artifacts.

Pod Expander ML305

The Pod Expander is a front-end device designed to allow up to four Poddevices to connect to any MacLab or PowerLab that does not have Podports. The Pod Expander provides the same “hot plugability” as that of thePowerLab systems that have built-in Pod ports. It is compatible with thefull range of ADInstruments Pods.

System CompatibilityThe Pod Expander connects to PowerLab or MacLab hardware units in thesame way as a conventional ADInstruments Front-end. The Pod Expanderconnects both to the I2C expansion bus and up to 4 of the analog inputs ofthe MacLab or PowerLab.

The following versions of Chart and Scope software are required for thePod Expander and Pod support:



Some early models of MacLab/4S, /8S and /16S systems along withPowerLab/4S, /8S and/16S systems manufactured before December 1997do not support the operation of the Pod Expander. The software listedabove will generate an appropriate message dialog if this is the case. Ifyou should see this error message or are having trouble getting the PodExpander to work then call your ADInstruments representative.

Theory of OperationThe Pod Expander allows the addition of up to four Pod devices to aMacLab or PowerLab hardware unit that has no built in Pod support. ThePod Expander gets its power and control from the I2C expansion port onthe rear of the MacLab or PowerLab. The Pod Expander reserves four I2Cfront-end locations for the four Pod channels and provides the necessaryswitching and power distribution for each Pod. The PowerLab softwarewill periodically scan each Pod input on the Pod Expander to see if a Podis attached. If it finds one, the Pod will be installed on that channel.
