Patent No. 10,989,699
Methods and systems are disclosed for analyzing and treating a fluid containing a peroxyacid and/or peroxide. A method of analyzing the fluid includes introducing into the fluid a decomposition agent that catalyzes decomposition of the peroxyacid and/or peroxide into decomposition products including oxygen, then directly or indirectly measuring an amount of oxygen produced after introduction of the decomposition agent, and determining an amount of the peroxyacid and/or peroxide present in the fluid. The amount of peroxyacid and/or peroxide in the fluid can also be monitored and controlled by further adjusting the amount of the peroxyacid and/or peroxide in the fluid based on the determined amount thereof. A system for performing the methods includes a decomposition agent infusion device for introducing the decomposition agent into a fluid sample, and a sensor for directly or indirectly measuring an amount of oxygen produced after introduction of the decomposition agent.

Patent No. 10,977,726
Systems and methods for providing a separate interest rate for an individual transaction are disclosed. A system may provide a service associated with a account having an account balance and an associated first interest rate. The system may include a service device having one or memory devices storing instructions and one or more processors configured to execute the instructions to perform a separate interest rate service process. The process may include providing a separate interest rate service offer to a client device and receiving a separate interest rate selection from the client device. The process may also include determining a selected portion of the account balance corresponding to an amount to which a second interest rate, different from the first interest rate, is to be applied based on the separate interest rate selection.
