Abstract: A system for regulating a pump down operation may include a controller, a motor drive, a parameter estimation unit and a controller design unit. In examples, the controller may be configured to identify a difference between a downhole tension set-point to an actual downhole tension. The motor drive may be configured to adjust a line speed set point of the motor drive based at least in part on the difference from the controller to create an actual line speed from the motor drive to follow the downhole tension set-point. The parameter estimation unit may be configured to produce a fluid drag coefficient, a friction coefficient, and a line speed delay constant. The controller design unit may be configured to send one or more control gains to the controller based at least in part on the fluid drag coefficient, the friction coefficient, and the line speed delay constant.

Abstract: In general, in one aspect, embodiments relate to a method that includes assembling a downhole tool from a plurality of subassemblies with a robotic tool assembly disposed on a subsea tree at a sea-floor in a subsea environment. The method may also include introducing the downhole tool into a wellbore, traversing the wellbore with the downhole tool to reach one or more target depths, performing at least a wellbore operation with the downhole tool at the one or more target depths, and retrieving the downhole tool from the wellbore after performing the wellbore operation.

Abstract: A system and method for content delivery across a heterogenous multi-display environment are disclosed. In one embodiment of the system, each smart device in the multi-display environment contains a display, a processor, non-transitory memory, and storage, interconnected by a busing architecture. Each device also has a wireless transceiver. The system obtains device characteristics, including display size, display brightness, resolution, device form factor, display orientation, and relative physical positioning, for example. The system divides the content into sections, allocating each to a device based on these characteristics and physical adjacency. Consequently, sections displayed on adjacent devices form contiguous portions of the content. The system synchronizes the rendering of the sections across devices, ensuring a unified and contiguous content display.

Abstract: The present disclosure generally relates to systems and methods for processing recurring payment transactions. In various embodiments, the system receives details of the set of recurring payment transactions and stores the details in a recurring transaction details table. The system generates a virtual payment instrument and associates it with the consumer's payment instrument. The system transmits the virtual payment instrument to the consumer. The system then generates a set of payment tokens for the set of recurring transactions and links the tokens to the virtual payment instrument. Each token is associated with a discrete recurring period. The system encodes each token with a sequence of values and stores the tokens in the recurring payment token table. The system receives a recurring transaction request that includes the virtual payment instrument. The system validates the request against a token associated with the recurring period, processes the transaction, and deletes the token.

Abstract: A method of facilitating a transaction with a payment card of a cardholder. The method includes receiving a deceptive PIN comprising a set of characters in which one character is a deceptive character. The deceptive character is different than each of a set of actual characters of an actual PIN of the payment card. The method includes identifying the deceptive character and a position of the deceptive character among the set of characters of the deceptive PIN. The method includes determining a reconstructed PIN by replacing the deceptive character with a corresponding actual character at the position in the deceptive PIN. The actual character is determined based on a predefined mathematical expression and a predefined value for the predefined mathematical expression. The method includes authenticating the reconstructed PIN by matching the reconstructed PIN with the actual PIN. The method further includes facilitating the transaction upon successful authentication.

Abstract: Systems and methods are provided for authenticating a user in connection with a network transaction by the user, based on a biometric combination for the user. One exemplary method includes receiving an authorization request for a network transaction by a user where the authorization request includes biometric data representing at least first and second biometrics of the user. The method also includes converting the biometric data to a personal identification number (PIN) specific to the biometric data, where the first biometric is converted to a first character of the PIN and the second biometric is converted to a second character of the PIN. The method further includes appending the PIN to the authorization request and transmitting the authorization request to an issuer, thereby permitting the issuer to approve or decline the network transaction based, at least in part, on the PIN included in the authorization request.

Abstract: Systems and methods for facilitating authentication for payment transactions using pattern-based time bound passwords. More specifically, techniques disclosed herein enable authentication of payment transactions performed by a user at a merchant terminal based on a pre-registered pattern provided by the user within a pre-defined time period limit. The pre-registered pattern drawn in the pre-defined time period is registered as a password for authenticating any payment transaction performed by the user using a payment card which is associated with an account of the user in an issuing bank. If the user provides the pre-registered pattern within the pre-defined time period limit, the payment transaction is authenticated. In another embodiment, such pattern-based time bound password is used as a second level authentication in which first level authentication is performed by a personal identification number.

Abstract: A method for facilitating transactions is provided. Various users register their payment modes to avail a payment mode interchange service offered by a server for online purchases. During registration, the users specify corresponding offer amounts in exchange for allowing purchases of other users to be performed by using their payment modes. When an offer on a purchase is not applicable on a payment mode of a first user, the first user is recommended by the server to make the purchase by using a payment mode of a second user on which the offer is applicable. The payment mode of the second user is charged with a purchase amount of the purchase and the offer amount specified by the second user is billed on the payment mode of the first user. The second user receives the offer amount and the first user receives an incentive associated with the offer.
