Methods and devices for blood pressure monitoring may include receiving one or more sensor measurements from the at least one sensor. The methods and devices may further include determining at least one of a first blood pressure indication using a first regression representation based on the one or more sensor measurements, a second blood pressure indication using a second regression representation based on the one or more sensor measurements, or a third blood pressure indication using a third regression representation based on the one or more sensor measurements. The methods and devices may include performing a blood pressure selection procedure using the first blood pressure indication, the second blood pressure indication, and the third blood pressure indication to determine an estimated blood pressure indication based on one or more classification characteristics. The methods and devices may further include transmitting the estimated blood pressure indication to the output device.

Blood pressure determinations

Methods and devices for heart rate monitoring may include determining whether an adjustment triggering condition has been met. Moreover, the methods and devices may include, in accordance with a determination that the adjustment triggering condition has been met, adjusting the second sensor indication to obtain an adjusted second sensor indication based at least on the difference between the first sensor indication and the second sensor indication. The methods and devices may further include, in accordance with a determination that the adjustment triggering condition has not been met, transmitting the second sensor indication to the signaling filter.

Photoplethysmography (PPG) indication discontinuity detection and correction

A wearable computing device comprises one or more motion sensors, a first circuit, and a second circuit. The one or more motion sensors are configured to measure swing motion. The first circuit is in communication with the one or more motion sensors and configured to translate measurements of the swing motion to machine-readable motion data and identify from the machine-readable motion data a golf shot in which a golf club held by a golfer contacts a golf ball. The second circuit is configured to increment a golf score of the golfer responsive to the golf shot being identified.

Golf shot detection

A device comprises a global positioning system (GPS) sensor and a circuit. The GPS sensor is switchable between a high power state and a lower power state. The circuit is configured to dynamically adjust a power state duty cycle of the GPS sensor based on at least a golf-event interrupt. The power state duty cycle defines a percentage of a period in which the GPS sensor operates in a high power state relative to a lower power state.

GPS sensor control

A method of optical heart rate sensing includes receiving a motion frequency from a motion sensor and receiving an optical signal from an optical sensor. The motion frequency is then filtered from the optical signal, and an estimated heart rate frequency is determined based on the filtered optical signal. A heart rate is reported that is based on the motion frequency, but not based on the estimated heart rate frequency, when a local neighbor magnitude ratio of the estimated heart rate frequency is below a confidence threshold.
