Abstract: Transaction data that represents transactions may be associated with one or more generated tags based on characteristics associated with the transactions. A set of suggested payment amounts for paying an account balance may be determined based on the tagged transactions. Information about at least one suggested payment amount may be presented at a user device.

Abstract: Tags for transaction records can be generated to represent characteristics of the transaction records not represented by typical characteristics of the records. Once generated, the transaction records can be modified to include the tags. Responsive to requests for transaction information, a set of transactions can be identified based on tags of the transactions and information about the transactions can be provided to a user interface.

Abstract: Enhanced searching at a user interface may be enabled by tagged transaction records. When a search query is received at the user interface, a user device may determine a set of suggested search queries.

Abstract: A servo valve including a piezo-electric actuator, a flexible linkage, and control valves. The piezo-electric actuator is actuatable along a piezo stack axis. The flexible linkage is coupled to the piezo-electric actuator at opposite axial ends of the actuator. Control valves are disposed at laterally opposite sides of the piezo stack axis and include respective valve stems coupled to the flexible linkage. The flexible linkage may be configured to transfer motion of the piezo-electric actuator along the piezo stack axis to a motion of the valve stems along an amplification axis that is transverse to the piezo stack axis to open and close the control valves.
