摘要： An electronics module receives biosignals, such as ECG, electrocardiogram, signals, from sensors on a wearable article and processes these signals to provide data and information to a user electronic device, such as a mobile phone. The user electronic device and/or electronics module is operable to determine whether the quality of the signal is above or below a predetermined level and to display a real-time biosignal trace on the user electronic device when the quality of the signal is high. The high-quality signal is also stored on user electronic device. When the signal quality is low, the user electronic device displays a composite trace instead of a real-time trace. The composite signal being composed of the stored high-quality trace modified by a current biosignal characteristic (such as current R-R value). The quality of the signal may be determined by an activity level of the user or motion level such as determining whether the wearer of the electronics module is relatively stationary or whether the wearer is moving, running etc, as noise of the displayed trace would otherwise increase with wearer activity. This arrangement provides a trace display that appears to be relatively noise-free and therefore can be understood by the wearer.

摘要： The invention provides a wearable device to obtain and display bio signal data to a user based on their activity level context (such as running). It comprises better signal processing when a lot of signal noise is being generated and this provides a displayed trace that appears to be relatively noise-free and better understood by the wearer. An electronics module receives biosignals such as electrocardiogram (ECG) signals from sensors on a wearable article and determines whether the activity level is above or below a predetermined level. It displays a first representation of the data (e.g. real-time) on the device when the determined activity level is low (i.e. the quality of the signal is high).When the determined activity level is high (e.g. the signal quality is low), the device displays a second representation comprising a composite of the first representation modified using characteristics obtained from the biosignal data.

摘要： Obtain an array of candidate peaks from a heartrate signal S201. The candidate peaks comprise timestamp values representing when the candidate peaks occur. Inter-beat interval (IBI) values are determined for the array of candidate peaks. The IBI values represent the time intervals between successive candidate peaks, i.e. the R-R interval S202. One or more statistical measures are calculated for the IBI values S203. For example, an average (e.g. mean) and a standard deviation. Using the one or more statistical measures, it is determined whether a correction should be applied to the array of candidate peaks S204. For example, if the standard deviation is larger or smaller than a certain percentage of the mean. If a correction should be applied, a peak is inserted into and/ or removed from the array of candidate peaks S205. Peak detection may rely on a heartrate signal sequentially crossing an upper and lower percentile respectively.

摘要： This invention describes a wearable device related to electrocardiogram (ECG) monitoring technology. An ergonomically designed wireless smart band pair for continuous ECG monitoring and analysis is disclosed. The pair comprises a primary and a secondary smart band with integrated electrodes. When the smart bands are worn around the two wrists, the electrodes contact the skin. The primary smart band acquires biopotential data from the first wrist while the secondary smart band acquires biopotential data from the second wrist and sends it wirelessly to the primary smart band. The primary smart band processes biopotential data from both wrists to acquire high-fidelity ECG waveform data without the need for completing a circuit via leads and/or touching and holding auxiliary electrodes. The primary smart band analyzes the acquired ECG signal in real-time and generates pertinent alarms. It also stores all ECG information locally and wirelessly transmits this information to external devices.

摘要： A method for determining the degree of parallel activation of a heart undergoing pacing includes calculating vectorcardiogram (VCG), or electrocardiogram (ECG), or electrogram (EGM) waveforms from right ventricular pacing (RVp) and left ventricular pacing (LVp). A synthetic biventricular pacing (BIVP) waveform is generated by summing the VCG of the RVp and LVp, or by summing the ECG of the RVp and the LVp, or by summing the EGM of the RVp and the LVp. A corresponding EGM or ECG or VCG waveform from real BIVP is calculated. The method includes comparing the synthetic BIVP waveform and the real BIVP waveform and calculating time to fusion by determining the point in time in which the activation from RVp and LVp meets and the synthetic and the real BIVP curves start to deviate. A delay in time to fusion indicates a higher degree of parallel activation.

摘要： In some embodiments, techniques capable of obtaining high-quality fetal ECG (fECG) information using as few as two composite (maternal and fetal) maternal abdominal ECG (aECG) signals to derive the fetal ECG information are provided. In some embodiments, maternal ECG information and fetal ECG information are both obtained from the aECG signals, and are either presented or stored. The techniques may use novel proposed diffusion-based channel selection criteria. To validate the proposed techniques, analysis results of two publicly available databases are described, and compared with other available techniques in the literature.

摘要： This relates to a monitoring system capable of measuring a plurality of vital signs. The monitoring system can include a plurality of sensors including, but not limited to, electrodes, piezoelectric sensors, temperature sensors, and accelerometers. The monitoring system can be capable of operating in one or more operation modes such as, for example: capacitance measurement mode, electrical measurement mode, piezoelectric measurement mode, temperature measurement mode, acceleration measurement mode, impedance measurement mode, and standby mode. Based on the measured values, the monitoring system can analyze the user's sleep, provide feedback and suggestions to the user, and/or can adjust or control the environmental conditions to improve the user's sleep. The monitoring system can further be capable of analyzing the sleep of the user(s) without directly contacting or attaching uncomfortable probes to the user(s) and without having to analyze the sleep in an unknown environment (e.g., a medical facility).
