Publication number: 20240215834Abstract: Temperature sensors and/or optical sensors can be used to determine whether an electronic device is worn or not worn by a user of the electronic device (e.g., on-wrist or off-wrist). In some examples, the temperature sensors can serve as a complement or a replacement to optical sensors when determining on-wrist or off-wrist. In some examples, detecting, via temperature sensors, a temperature difference between opposite sides of the wearable device (e.g., front face and back face) indicates on-wrist.Type: ApplicationFiled: December 14, 2023Publication date: July 4, 2024Inventor: Wegene H.

Publication number: 20230332960Abstract: This relates to using light emitting diodes (LEDs) and/or photodiodes (PDs) on a device intended to come in contact with a user for temperature sensing. In some examples, the LEDs and PDs can be used for both biometric sensing and user temperature sensing. By biasing the LEDs and PDs with different bias currents and obtaining different diode base-emitter voltages (VBE) having known negative temperature coefficients, changes in VBE (?VBE) can be computed and used to estimate user temperature. In particular, a measurement circuit including a current source or sink, an amplifier, and an analog to digital converter (ADC) can be connected to each LED and PD. Different bias currents can be applied to the LEDs and/or PDs (the PDs being forward-biased instead of their normal reverse-biased mode for biometric sensing) to obtain different VBE measurements, and those differences can be used in equations to estimate the temperature of the user.Type: ApplicationFiled: March 28, 2023Publication date: October 19, 2023Inventors: Wegene H.

Publication number: 20230098236Abstract: Robust estimation of temperatures inside and outside a device can be achieved using one or more absolute temperature sensors optionally in conjunction with thermopile heat flux sensors. Thermopile temperature sensing systems can measure a temperature gradient across two locations within the device, to estimate absolute temperature at locations that are impractical to measure using absolute temperature sensors. Using heat flux models associated with the device, the thermopile temperature sensing system can be used to estimate temperature associated with objects that contact an outer surface of the device, such as a user's skin temperature. Additionally, the thermopile temperature sensing system can be used to estimate ambient air temperature. Within a device, temperature measurements from the thermopile temperature sensors can be used to compensate sensor measurements, such as when the accuracy or reliability of a sensor varies with temperature.Type: ApplicationFiled: September 6, 2022Publication date: March 30, 2023Inventors: Wegene H. TADELE, Habib S. KARAKI, James C. CLEMENTS, Chin S. HAN, Craig C. D'SOUZA, Daniel W. LABOVE, Esther CHEN, Joseph R. LEE, Kuo Jen HUANG, Wanfeng HUANG, Fred Y. CHOU, Hongling CHENG, Ali M.
