Abstract: A pressure exchanger includes a rotor configured to exchange pressure between a first fluid at a first pressure and a second fluid at a second pressure. The rotor forms ducts that are routed from a first distal end to a second distal end. The pressure exchanger further includes a first end cover that forms a high pressure in (HPIN) port configured to provide the first fluid at the first pressure in a substantially axial direction into the ducts. The first end cover forms a low pressure out (LPOUT) port configured to receive the first fluid from the ducts at a third pressure. The pressure exchanger further includes a second end cover that forms a low pressure in (LPIN) port configured to provide the second fluid at the second pressure into the ducts and forms a high pressure out (HPOUT) port configured to receive the second fluid from the ducts at a fourth pressure.

Abstract: A helper SDK embedded in a native application performs local operations on behalf of a web application affiliated with the helper SDK. The helper SDK may perform security functions such as fingerprint or face biometric verifications as well as access device-specific hardware such as a camera or secure memory. The web application may use an 0Auth technique for access and refresh tokens. In a transaction system, when a user is confirmed via the security function, order details are passed to the web application with a refresh token and ciphertext confirmation data is returned to the native application for completion of the transaction.

Abstract: The system and methods allow a user to request and receive an electronic coupon using a client application on an internet-enabled device such as a mobile phone and use the electronic coupon when making a purchase at a store. Specifically, the mobile device requests and receives the mobile coupon from a server or a network of servers. The server or network of servers determines which if any electronic coupon(s) to send to the client application and sends an electronic coupon to the client application. The client application displays the electronic coupon with a coupon identifier on the display of the mobile device. The user then uses the mobile device to enter the coupon identifier into a point-of-sale terminal to trigger the discount or other special deal offered on the electronic coupon when making a purchase at the point-of-sale terminal.
