Abstract: A wearable biometric sensing ring apparatus for continuous heart rate and blood pressure monitoring having a ring housing for retention on a finger of a user, a photoplethysmograph (PPG) sensor disposed within the housing on an interior surface of the ring to contact or be placed adjacent the finger to register a pulse rate of the user, a first electrode and second electrode disposed within the housing on said interior surface of the ring to contact the finger on a first side of the user's body, and a third electrode disposed on an exterior surface of the ring housing to contact a contralateral portion of the user's body. A combination of first, second and third electrodes are configured for obtaining electrocardiogram (ECG) measurements.

Abstract: A wearable biometric sensing ring apparatus for continuous heart rate and blood pressure monitoring having a ring housing for retention on a finger of a user, an electrodermal activity (EDA) sensor disposed within the housing so as to contact a location of the skin of the finger when the housing is retained on the finger, the EDA sensor configured for measuring changes in skin impedance indicative of SNS activation; a biometric sensor disposed within the housing in proximity to the EDA sensor so as to contact at or near the location of the skin of the finger. Application software is provided for assessing the physiological state of the user based on acquired EDA sensor data and biometric sensor data.

Abstract: A biometric sensing apparatus for estimating the emotional state of a user. A self-contained biometric sensing ring is worn on the finger (or fingers) of the user during their normal activities. Biometric information is collected and sent wirelessly to the user's mobile device configured with application programming for analyzing and displaying the biometric information. The biometric ring is configured with sensors that the structure of the ring retains at a proper pressure against the finger of the user. The sensors comprise at least electrodermal response (EDR), photoplethysmograph (PPG), temperature, and acceleration. The ring has a self-contained power source, and is configured for adjustably fitting a wide range of users.

Abstract: An apparatus for interoperably utilizing multiple biosensor data obtained from a finger of the user. A biometric sensor board is retained in a housing adapted for retaining a finger of the user and maintaining multiple sensors in contact with the skin thereof. Implementations are described for fingertip and ring mounted sensor boards. In one implementation, these sensors can be sensors electrodermal response (EDR), or photoplethysmograph (PPG) signals, or temperature, or acceleration in three axes, and combinations thereof. The biometric sensor board registers and processes the signals from the sensors and communicates them to a mobile device which interoperably utilizes multiple sensor information to determine aspects of user emotional state within an application to generate results which are displayed on the mobile device.
