Abstract: This relates to methods for measuring irregularities in a signal and corresponding devices. The devices can include a PPG sensor unit configured to detect multiple occurrences of a given event in the measured signal(s) over a sampling interval. In some instances, the device can register the occurrences of the events. In some examples, the device can include one or more motion sensors configured to detect whether the device is in a low-motion state. The device may delay initiating measurements when the device is not in a low-motion state to enhance measurement accuracy. Examples of the disclosure further include resetting the sample procedure based on one or more factors such as the number of non-qualifying measurements. In some examples, the device can be configured to perform both primary and secondary measurements, where the primary measurements can include readings using a set of operating conditions different from the secondary measurements.

Abstract: A system for a distributed repository includes an input interface and a processor. The input interface is to receive a request to change a portion of code. The processor is to determine a change reference and an existing reference, indicate to lock one or more repositories, determine whether swapping references is approved by a vote, and in the event that swapping references is approved by a vote, swap the references and indicate to unlock the one or more repositories.
