The study objective is to collect heart rate, respiration rate and motion data of patients admitted to sleep lab and to determine the accuracy level of the EarlySense system vs. the monitors used in sleep lab (e.g., Polysomnography, respiratory belts, ECG, etc..) . Data regarding sleep condition, scoring and quality of sleep and in and out of bed status, patient turns will also be collected and compared to data collected by EarlySense contactless monitor. Different patient population will be monitored including obese, morbidly obese, patients with or without obstructive/central apnea, patients with or without arrhythmia as well as healthy population who arrive to sleep lab for general evaluation will be monitored
