Abstract: An account validation system may include an account validation server. The server may store an order purchase history for accounts. The order purchase history may include a purchased product. The server may obtain an account identifier from a user device for a given user and communicate the purchased product to the user device for display thereon based upon a corresponding account associated with the account identifier. The server may communicate a fake product that is inconsistent with the order purchase history to the user device and based upon the order purchase history for the corresponding account. The server may also cooperate to prompt the given user to differentiate the purchased product from the fake product, and determine, based upon the user device, whether the given user has differentiated the purchased product from the fake product, and when so, validate the corresponding account.

Abstract: A system may include a point-of-sale (POS) terminal and a database configured to store respective package quantity data for different package configurations for each product from among products, and to store respective product quantity promotion threshold data for each product. The system may also include a controller coupled to the database and the POS terminal and configured to calculate, based upon the stored package quantity data, a given product quantity for a given purchase of a plurality of different package configurations of the given product at the POS terminal. The controller may be configured to compare the given product quantity to a respective product quantity promotion threshold from among the stored product promotion threshold data, and when the given product quantity is above the respective product quantity promotion threshold, then award a digital promotion for redemption.

Abstract: A method for adjusting the operation of a turbomachine integrated with an exhaust gas recirculation (EGR) system is provided. The method may utilize the composition of an inlet fluid entering the turbomachine. The method may also utilize a variety of turbomachine operating data.

Abstract: A turbine engine. The turbine engine may include an incoming fuel stream and a lubricating oil recirculation system. The lubricating oil recirculation system may include a heat exchanger such that waste heat from the lubricating oil recirculation system is transferred to the incoming fuel stream.

Abstract: A system for determining a target exhaust temperature for a gas turbine including: determining a target exhaust temperature based on a compressor pressure condition; determining a temperature adjustment to the target exhaust temperature based on at least one parameter of a group of parameters consisting of specific humidity, compressor inlet pressure loss and turbine exhaust back pressure; and adjusting the target exhaust temperature by applying the temperature adjustment.
