The present disclosure provides computer-implemented methods, systems, and devices for controlling an external shared clock in a computing system with a plurality of system on a chips (SoCs). To do so, while a first SoC is in a low power mode, the second SoC receives a wake-up input that causes the second SoC to exit a low power mode. The second SoC asserts a clock request signal line to activate an external shared clock. The clock control system determines a state associated with the external shared clock, wherein the external shared clock is external to the first SoC. The clock control system, in accordance with a determination that the external shared clock is in an off state, transmits a signal to the external shared clock to cause the external shared clock to enter a startup state and begin producing a shared clock signal.
The present disclosure provides computer-implemented methods, systems, and devices for estimation of a user's blue light exposure using the camera of a user computing device. A user computing device captures, using an ambient light sensor, information associated with a light environment of a user computing device. The user computing device determines a target exposure time. The user computing device captures, using a camera, image data by exposing a sensor of the camera to light for a time based on the target exposure time. The user computing device calculates white balance values for the captured image data using an automatic white balance algorithm. The user computing device discards the captured image data. The user computing device generates, based on the automatic white balance values, a blue light exposure value.

Temperature changes to the proxy temperature may be evaluated against a threshold to determine whether the user's core body temperature has also increased, which may be indicative of one or more physiological symptoms or events. Furthermore, additional physiological variables such as respiration rate, nocturnal heart rate, and heart rate variability may be analyzed for early signs of impending illness. A trained machine learning classifier can output the predicted illness status of an individual based on these parameters.

Alternative pairing is used to enable communication between devices, but without conventional processes required for pairing. Moreover, multiple wireless bonds may be enabled, where both a device is linked to another device and an account is associated with the device and also a backend server. Once an appropriate bond is established, a streaming app (or partial or lightweight version of an application including a selected subset of application functionality) can be streamed to a device such that the user can enter information that can be transmitted to a paired device over the wireless connection. This can enable the association of the device to be performed with respect to the backend servers of the relevant provider. Such an approach can also establish a mechanism for the user to create an account while downloading the full application, or remainder of the application in some embodiments, in the background.

Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.
