NameDescription                              ConstraintsTypeOn
Is Enabled        If set to false the element is completely omitted when the experiment is run                Boolean         
Title        Title of the element                String         
HeartLive Settings
HeartLive IP Address        Defines the HeatLive server IP address                String         
No-delay Mode        Defines whether the Nagle's algorithm is disabled on the TCP port, such that it sends the output data without a buffering delay.                Boolean         
ECG Port        Defines a TCP port number for the HeartLive ECG signals.                Int32         
Coherence Port        Defines a TCP port number for the HeartLive coherence signal.                Int32         
Channel Configuration
Actual Sampling Rate        Returns the actual sampling rate of HeartLive sensor                Double         
Selected Channels        Defines what signal channels are selected for acquisition within EventIDE. Selected channels are registered in the EventIDE signal pool at runtime and become available for the signal analysis elements.                IList         
Selected Channel Count        Indicates how many signal channels are currently selected for acquisition                Int32         
Total Channel Count        Indicates how many signal channels are available for acquisition in the total                Int32         
Buffer Size        Defines the size (in samples) of a circular buffer that stores incoming signal data.                Int32         
Signal Generator
Signal Source        Defines a source for the signal. The emulated rhythmes can be used for offline validation of the chosen analysis settings                enEmul..         
Emulated Sampling Rate        Defines the emulation sampling rate (samples per second), when data is generated or streamed from a file.                Double         
Primary Frequency        Defines the frequency of the primary rhythm in the generated signal, in Hz. Assign the zero to exclude the primary frequency from the generated signal.                Double         
Secondary Frequency        Defines the frequency of the secondary rhythm in the generated signal, in Hz. The secondary frequency magnitude is a half of the primary frequency magnitude. Assign the zero to exclude the secondary frequency from the generated signal.                Double         
Noise Level        Defines the noise level (in % to the norm magnitude of the primary frequency). The noise is added to the generated signal. Assign the zero the exclude the noise from the generated signal.                Double         
External Datafile        Opens the dialog for selecting a data file containing a stream of double numbers representing a signal. If a file name without a path is defined, the data file will be picked up in the location of the experiment file.                String         
Runtime Control
Reset Signals Now        Runtime commands that resets the signal buffers and data acquisition                Boolean         

HeartLive Buffer Element allows real-rime acquisition and buffering signals from the HearLive sensor. The signals include ECG, IBI, HRV and a second-order coherence score. The buffered signal data can be used by the signal processing elements in EventIDE. For example, the signal data can be monitored, analyzed or used for neuro-feedback control in experiments. In order to use this element, you must have the HeartLive sensor connected in a network and running. The element is in a beta state.
