Abstract: A method and an apparatus for switching an ECG measurement mode, a wearable device, and a computer-readable storage medium. The method includes: receiving two successive pieces of PPG data transmitted by an optical heart-rate sensor, where the PPG data is generated by a contact between a measurement electrode and a skin; calculating a difference between the two received pieces of the PPG data; and controlling switching among measurement modes based on the difference, where the measurement modes comprise an ECG wristband mode and an ECG chest-lead mode Manual switching of an ECG measurement mode is avoided with simple operations, high efficiency, and more intelligence.

Abstract: A machine may be configured to perform management of a lockdown of entity-related data in a database. For example, the machine identifies a replication lag trend associated with replicating data from a first data center to a second data center. The machine causes, based on the replication lag trend, a replication of data associated with a particular entity from a first record of the first data center to a second record of the second data center. The machine causes a lockdown, for a period of time, of the second record. The lockdown prevents servicing requests for data associated with the particular entity that are received from client devices associated with users related to the particular entity. The machine dynamically adjusts the period of time based on a monitoring of a completion of the replication. The machine causes a lifting of the lockdown based on the dynamically adjusted period of time.

Abstract: In some embodiments, the disclosed subject matter involves an entity routing service to route user requests for an application service to a particular data center based on the user's entity status. The user's entity status is defined by at least the application service requested, and may include the user's organization, geographic area and other criteria. The routing may be effected at the frontend application server level rather than at the backend. Other embodiments are described and claimed.
