Abstract: The present disclosure relates generally to tokenization of a co-network account. A co-network account, as used herein, refers to an account associated with a first transaction processing network for processing transactions initiated using the account and a second transaction processing network for processing transactions initiated using the account. During provisioning of a co-network account onto a user device, a first token is generated for use with the first transaction processing network and a second token is generated for use with the second transaction processing network. Embodiments use the authentication result generated during the provisioning of the first token for the provisioning of the second token. Embodiments automatically provision multiple payment tokens on the user device upon determining that the account is associated with more than one transaction processing networks (e.g. the account is a co-network account).

Abstract: In accordance with presently disclosed embodiments, a system and method for using fuel cells to generate electricity for powering well stimulation equipment (e.g., high pressure hydraulic pumping units) at a well stimulation site are provided. The fuel cells may be coupled to the stimulation equipment via a DC/AC converter and, in some embodiments, via a variable frequency drive (VFD). The fuel cells may be arranged in a fuel cell stack that is used to generate electricity to power various electrical devices (e.g., electric motors) on the equipment. The fuel cells generally operate at higher efficiencies than is available through the use of diesel engines. In addition, the fuel cells may require less frequent refueling and provide a more centrally located area for refueling, lower emissions, and quieter operations than are currently available using diesel engines.

Abstract: The disclosure herein generally relate to scene change detection, and, more particularly, to use of Unmanned Vehicle (UV) to inspect a scene and perform a scene change detection using UVs. When a UV performs visual inspection of an area or an object, due to various factors, such as but not limited to environmental factors, and movement of object and/or the UV, image of the area/object captured by the drone lacks clarity, which in turn makes detection of any object a difficult task. The UV disclosed herein uses a multi scale super pixel technique for visual change detection, in order to solve the aforementioned issues. In an embodiment, the UV captures an image, identifies a reference image that matches the captured image, and generates a change map. The multi-scale super pixel analysis is then performed on this change map to detect changes between the captured image and the reference image.

Abstract: A single sign-on system using blockchain is disclosed. The single sign-on system may interconnect various organization systems over a peer-to-peer network, with each organization system having a blockchain node and an application programming interface (API). The blockchain node invokes and uses a smart contract to write registration credentials to the blockchain during a registration process. During a login process, the blockchain node invokes the smart contract to determine whether login credentials match stored login credentials in the blockchain. In response to matching login credentials, the API may generate a single sign-on token that can be used by a user device to access one or more organization systems connected over the network.

Abstract: Systems for decoupling and updating pinned certificates on a user device are disclosed. A mobile application having a hardcoded pinned certificate may be installed on a user device. The pinned certificate may be decoupled from the mobile application and stored on the user device. In response to the mobile application attempting to establish a secure connection with a server, the system may check whether the decoupled pinned certificate is current by querying a certificate repository. In response to determining that the pinned certificate is out of date, the system may transmit the current certificate to the user device to update the decoupled pinned certificate.
