Abstract: One embodiment described herein takes the form of a wearable electronic device, such as a watch, including a housing, a memory and a processor located in the housing, and three or more sensors. Each sensor of the three or more sensors is configured to generate a measurement of a parameter. Each sensor of the three or more sensors is located in a different region in the housing. The processor is configured to execute instructions stored in the memory. In response to execution of the instructions by the processor, the processor is configured to generate an adjusted measurement of the biometric parameter using at least the measurements of the parameter generated by the three or more sensors. The parameter is a temperature, and the biometric parameter is a body temperature of a user.

Abstract: Detecting user contact with one or more electrodes of a physiological signal sensor can be used to ensure physiological signals measured by the physiological signal sensor meet waveform characteristics (e.g., of a clinically accurate physiological signal). In some examples, a mobile and/or wearable device can comprise sensing circuitry, stimulation circuitry, and processing circuitry. The stimulation circuit can drive one or more stimulation signals on one or more electrodes, the resulting signal(s) can be measured (e.g., by the sensing circuitry), and the processing circuitry can determine whether a user is in contact with the electrode(s). Additionally or alternatively, in some examples, mobile and/or wearable device can comprise saturation detection circuitry, and the processing circuitry can determine whether the sensing circuitry is saturated.

Abstract: Disclosed herein are electronic devices, including wearable electronic devices, and components and configurations thereof, having one or more temperature sensors separated from the point of contact of the electronic device and an object, such as a user, whose temperature is being measured. In some embodiments, the electronic device includes both a temperature sensor and a light (visible, UV, and/or IR) emitter and sensor. Various embodiments are disclosed by which a temperature sensor may be shielded or separated from a light emitter/detector. A spacer may be used to separate the temperature sensor from the device's housing that contacts the object. The spacer may include a thermal path from the housing to the temperature sensor, and may be opaque to the light detected by a light detector.
