HeartMath emWave USB Harware Kit

emWave USB Hardware Package: includes the Ear Sensor for hands-free operation and a Finger Sensor. The USB Sensor features auto-gain control for increased sensitivity and less signal loss. 

USB Hardware Kit includes: 
* USB Module (Interface Device) 
* USB Finger Sensor with strap 
* USB Ear Sensor with lapel clip 

USB Sensor Hardware Package
*Compatible with emWave PC v1.0.6 or higher, emWave Mac, emWave Desktop and emWave Pro.

*USB Module is the interface device that powers the Finger and/or Ear Sensor and interprets the data going to the software program.

*Finger Sensor can accommodate a wider range of finger sizes (child to adult) without the use of foam inserts or having to insert finger from the backside of the unit. The new double-wrapped strap allows for a more snug fit and less signal loss, while still providing less restriction to the user. 

*Ear Sensor allows user to keep working at their desk or table while running a session. The light spring action in the ear sensor makes wearing it barely noticeable. Lapel clip further reduces weight on the ear. 

Glossary of Terms

Cardiac Coherence--A mode of cardiac function in which the heart's rhythmic and electrical output is highly ordered. HeartMath research has shown that the positive emotions such as love, care, and appreciation increase coherence in the heart's rhythmic beating patterns. During states of cardiac coherence, brain wave patterns have been shown to entrain with heart rate variability patterns; in addition, nervous system balance and immune function are enhanced. Overall, the body functions with increased harmony and efficiency.

Coherence--Logical connectedness, internal order, or harmony among the components of a system. This term can also refer to the tendency toward increased order in the informational content of a system or in the information flow between systems. In physics, two or more waveforms that are phase-locked together (so that their energy is constructive) are described as coherent. Coherence can also be attributed to a single waveform, in which case it denotes an ordered or constructive distribution of power content. Recently, there has been a growing scientific interest in coherence in living systems. When a system is coherent, virtually no energy is wasted, because of the internal synchronization among the parts. In organizations, increased coherence enables the emergence of new levels of creativity, cooperation, productivity, and quality at all levels.

Heart Rate Variability (HRV)--The normally occurring beat-to-beat changes inheart rate. Analysis of HRV is an important tool used to assess the function and balance of the autonomic nervous system. HRV is considered a key indicator of aging, cardiac health, and overall well-being.

Stress--Pressure, strain, or a sense of inner turmoil resulting from our perception and reactions to events or conditions. A state of negative emotional arousal, usually associated with feelings of discomfort or anxiety that we attribute to our circumstances or situation.
