Abstract: A method for secure data synchronization and sharing between distinct cloud environments is disclosed. The method involves establishing a trust relationship between a data provider's private cloud deployment and a data consumer's public cloud deployment. Utilizing hardware processors, a cross-region group sharing token is generated and validated to facilitate secure communication and data traffic between the two cloud deployments. Upon validation, a firewall policy that previously restricted data exchange is disabled, allowing for the replication of a target database from the private cloud to a secure share area accessible by the public cloud deployment. The data consumer is then enabled to access and utilize the replicated database within this secure area. The method ensures consistent data management across both deployments by managing the synchronization of the replicated database with the data provider's original database, thereby maintaining data consistency and integrity.

Abstract: The present disclosure describes a system that monitors an alkaline battery pack to detect low voltage batteries before the low voltage batteries can leak. Battery packs may comprise an even number of batteries, operating in series. The system monitors a voltage over each pair of batteries in a battery pack. For example, a first voltage (V1) may be measured between a first battery and a second battery. The first voltage may be measured between ground and the middle of the battery pack. The second voltage (V2) may be measured between a third battery and a fourth battery (i.e., between the middle of the pack and the terminal). The system then estimates the lowest battery voltage (Vtest) by subtracting the higher voltage divided by two from the lower voltage. The resultant voltage (Vtest) is then compared to a threshold voltage (e.g., between 0.85-1.2 volts). If the resultant voltage (Vtest) is greater than the threshold voltage, then the device is allowed to continue operating.
