Name	Description	Constraints	Type
Control
Is Enabled	If set to false the element is completely omitted when the experiment is run	Design Time..	Boolean
Title	Title of the element	Design Time..	String
HeartLive Settings
HeartLive IP Address	Defines the HeatLive server IP address	Normal..	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.	Design Time..	Boolean
ECG Port	Defines a TCP port number for the HeartLive ECG signals.	Design Time..	Int32
Coherence Port	Defines a TCP port number for the HeartLive coherence signal.	Design Time..	Int32
Channel Configuration
Actual Sampling Rate	Returns the actual sampling rate of HeartLive sensor	Status..	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.	Design Time..	IList
Selected Channel Count	Indicates how many signal channels are currently selected for acquisition	Status..	Int32
Total Channel Count	Indicates how many signal channels are available for acquisition in the total	Status..	Int32
Buffer Size	Defines the size (in samples) of a circular buffer that stores incoming signal data.	Design Time..	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	Design Time..	enEmul..
Emulated Sampling Rate	Defines the emulation sampling rate (samples per second), when data is generated or streamed from a file.	Design Time..	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.	Design Time..	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.	Design Time..	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.	Design Time..	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.	Design Time..	String
Runtime Control
Reset Signals Now	Runtime commands that resets the signal buffers and data acquisition	Runtime Command..	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.
