Abstract: In one embodiment, an apparatus comprises a source system comprising a processing device coupled to memory. The processing device is configured to obtain an IO operation corresponding to an address of the source system. The IO operation comprises first user data. The processing device is further configured to store metadata associated with the IO operation in a first journal barrier of a replication journal of the source system and to close the first journal barrier. The processing device is further configured to determine that the first user data associated with the IO operation is missing from the first journal barrier and to obtain second user data from the address. The processing device is further configured to identify an interval from the first journal barrier to a second journal barrier and to provide the first journal barrier and the interval to a destination system.

Abstract: Systems and methods for monitoring fluctuations in the operation of the electromechanical valves of a fuel dispenser over a series of fueling transactions and identifying trends that may indicate mechanical wear of the valve or other fuel system issues. By identifying these issues before fuel dispenser performance is negatively affected, an operator may be notified and preventative maintenance or corrective action may be initiated before the issues affect the customer or gas station throughput.

Abstract: A secured framework for hosting secure and non-secure applications is provided. A master control apparatus includes an interface component for providing input to or output from the master control apparatus, and an interface communicating component for establishing a communications path to a portion of the interface component when a secured portion of the interface component is active. The interface communicating component provides data from a feature apparatus to the portion of the interface component over the communications path, and switches the communications path to refrain from providing data from the feature apparatus where the secured portion of the interface component is active. A security analyzing component can also be included to additionally or alternatively determine whether access is allowed to the portion of the interface component.
