A sphygmomanometer includes a blood pressure measurement unit that measures a blood pressure of a user based on a pulse wave signal in a pressurization process of increasing a cuff pressure indicating a pressure inside a cuff worn around a measurement site of the user, and a pulse rate measurement unit that measures a pulse rate of the user based on the pulse wave signal in the pressurization process. The blood pressure measurement unit determines whether to continue the pressurization process based on a pulse rate. The sphygmomanometer further includes a monitoring unit that monitors an arrhythmia of the user based on a pulse wave signal in the pressurization process.

A system and method are configured to provide a user with entertainment, for which one or more activities are prepared, each activity involving one or more participants. Specifically, the system and method are configured to obtain user information including the user's selection of an activity and a participant in the activity, receive images and sounds captured by at least one camera and one microphone attached to the participant, process the images and sounds, send the processed images and sounds to a client terminal associated with the user who selected the activity and the participant in the activity, and provide the user with a game based on a process of the activity.

A blood pressure monitor configured to removably mount to a cuff in a substantially symmetrical position with respect to a width of the cuff can include a housing defining an interior, a first port, and a second port. The first port can: secure to a first prong of the cuff when the cuff is mounted in a first orientation; receive and secure to a second prong of the cuff when the cuff is mounted in a second orientation; and enable fluid communication between the interior and at least one of a first fluid passage within the first prong and a second fluid passage within the second prong. The second port can: secure to the second prong of the cuff when the cuff is mounted in the first orientation; and receive and secure to the first prong of the cuff when the cuff is mounted in the second orientation.

A method of measuring noninvasive blood pressure includes determining a window for pulse detection for a patient, receiving a pressure signal measured from a measure sensor in a blood pressure cuff, and setting a pulse detection period for each heart beat based on the window and a heart beat indicator indicating at least one heart beat time for the patient. The pressure signal is then examined within each pulse detection period to identify a pressure peak therein. A blood pressure for the patient is determined based on the pressure peaks detected in the pressure signal.

Techniques and systems include predicting various health conditions using a photoplethysmography (PPG) signal or a video signal based on images of a patient's fingertip or other body portion captured using a mobile device. The video signal may be transformed into a pseudo PPG signal to measure blood volume changes in the patient's blood flow to derive data indicating a disease state or health-related characteristic, such as blood oxygen level, blood glucose level, heart rate variability, hemoglobin, respiration rate, or arrhythmia. Techniques involve real-time environment assessment and problematic issue detection, training an artificial intelligence (AI) model to measure signal quality so as to select high-quality signals from a range of signals, and domain adaption and transfer learning to make use of publicly available datasets.

An electrocardiogram device configured to transmit at least one signal responsive to a wearer's cardiac electrical activity can include a disposable portion and a reusable portion configured to mechanically and electrically mate with each other. The disposable portion can include a base having at least one mechanical connector portion, a plurality of cables and corresponding external ECG electrodes, and a first plurality of electrical connectors associated with the plurality of cables. The reusable portion can include a cover having at least one mechanical connector portion, a second plurality of electrical connectors configured to electrically connect with the first plurality of electrical connectors of the disposable portion, and an output connector port configured to transmit at least one signal responsive to one or more signals outputted by the external ECG electrodes of the disposable portion.
