Filar antenna element devices and methods
Single band and multiband wireless antennas are an important element of wireless systems. Competing tradeoffs of overall footprint, performance aspects such as impedance matching and cost require not only consideration but become significant when multiple antenna elements are employed within a single antenna such as to obtain circular polarization transmit and/or receive. Accordingly, it would be beneficial to provide designers of a wide range of electrical devices and systems with compact single or multiple frequency band antennas which, in addition to providing the controlled radiation pattern and circular polarization purity (where required) are impedance matched without substantially increasing the footprint of the antenna and/or the complexity of the microwave/RF circuit interfaced to them, whilst supporting multiple signals to/from multiple antenna elements in antennas employing them. Solutions present achieve this through provisioning one or more capacitive series reactances discretely or in combination with one or more shunt capacitive reactances. |

Embodiments of the present specification provide example blockchain-based data processing methods, mediums, and systems. One example method includes obtaining an available Nonce record for a target transaction from a Nonce list. The Nonce list comprises Nonce records, and each Nonce record comprises a version identifier of the Nonce list and a Nonce value. The available Nonce record to the target transaction is added. The target transaction in a blockchain is published. Prompt information indicating that the target transaction is an invalid transaction is received when a version identifier in the available Nonce record does not match the version identifier of the Nonce list; or a notification message indicating that the target transaction is processed is received when the version identifier in the available Nonce record matches the version identifier of the Nonce list and a replay attack detection is successfully performed by matching the available Nonce record with a Nonce record in the Nonce list. |

Rapid transaction settlement using virtual account
An automation computer can receive a set of instructions pertaining to a transaction. The automation computer can generate a request to generate and activate a virtual account, where the virtual account is associated with a transaction value and a transaction amount. The virtual account can be managed by an authorization computer that can load a transaction value onto the virtual account in an amount equal to the transaction amount. The authorization computer managing both issuer and acquirer functionality in a transaction settlement can settle the transaction rapidly using the loaded virtual account by depositing the transaction value associated with the virtual account directly into an account of a resource provider. |

Systems and methods for processing trailer repair requests submitted by carriers
In some embodiments, methods and systems are provided for facilitating submission of repair requests by carriers having to repair trailers to domicile facilities associated with the trailers. A central computing device provides a first graphical interface accessible by a computing device of a carrier having to repair a trailer in order to permit the carrier to submit a repair request indicating repair needed for the trailer. The central computing device then generates an invoice for the repair to the trailer directed to a domicile facility associated with the trailer. The central computing device also transmits an alert including the invoice to a computing device of the domicile facility associated with the trailer, receives a response from the computing device of the domicile facility associated with the trailer, and transmits a notification indicating whether the repair request has been approved by the domicile facility associated with the trailer. |

Automated clinical documentation system and method
A method, computer program product, and computing system for initially aligning two or more audio signals to address coarse temporal misalignment between the two or more audio signals. The two or more audio signals are detected by two or more audio detection systems within a monitored space. The two or more audio signals are subsequently realigned to address ongoing temporal signal drift between the two or more audio signals. |

Freight network system using modularized trailers
A computer system receives a freight request from a shipper, where the freight request specifies a destination for a load of the shipper. The computer system implements a selection process to select a freight operator to haul a corresponding trailer of the trailer module from a location of the shipper to a destination. The trailer module may be monitored using information transmitted from the trailer, to determine when the trailer is picked up and/or delivered at the destination. |

Business prediction method and apparatus
A business prediction method includes: obtaining a first business sample set and a second business sample set; performing training based on the first business sample set and the second business sample set to obtain a business prediction model, and predicting received to-be-predicted business information based on the business prediction model to obtain a business prediction result corresponding to the received to-be-predicted business information. A business prediction apparatus is further provided. The business prediction method and the business prediction apparatus take into account data features of some business samples of being rejected in a business validation, while considering business samples of passing the business validation. This restores a business scenario, reduces the waste of costs of the rejected samples, and balances demands for a modeling sample and a rejected sample reasonably when there are insufficient samples of passing the business validation. |

Systems and methods for utilizing compliance drivers to conserve system resources and reduce compliance violations
Systems and methods for utilizing compliance drivers to conserve system resources are provided. Data that corresponds to a pre-determined historical period may be used. A method may extract issue information, regulations data, operations loss data, drivers data, pending activities data and/or pending examinations data. The method may perform a plurality of transformations on the issue information, the drivers data, the regulations data, and the operations loss. The transformations may apply enterprise compliance hierarchy information and transform the data associated with the issue information, the drivers data, the regulations data, and the operations loss data into quarterly information. The method may include performing transformations on issue information, regulations data, operations loss data and drivers data. The method may perform final transformations in order to either allocate resources to remediate a compliance trend, remediate a compliance projection, or correct a current compliance issue. |
