In addition, the factor packet is distributed to physical links to which the factor packet is distributed, and a packet that is not the factor packet is distributed according to the distribution rule, which is based on, for each of the physical links constituting the LAG, a remaining bandwidth obtained by subtracting the usage bandwidth of the factor packet distributed to said physical link from the maximum available bandwidth of said physical link. |

Smart lock and method for automatically locking smart lock
The present disclosure provides a smart door lock and a method for controlling the smart door lock. The method may be implemented on a computing apparatus including a processor and a storage device. The method may include obtaining user information and determining whether the user information passes a verification. The method may further include in response to a determination that the user information passes the verification, controlling the smart door lock to perform an unlock operation. The method may further include determining whether the door on which the smart door lock is installed has a preset action within a preset time period and in response to a determination that the door has the preset action within the preset time period, controlling at least one component of the smart door lock to perform at least one operation. |

Vehicle allocation method and system
A vehicle allocation method and system are provided. Vehicle diagnostic data is received from vehicle-computing devices placed in vehicles. A diagnostic score is determined for each vehicle. A request for booking a ride is received from a customer device of a customer. A fare for the ride is determined for the vehicles. Options are transmitted to the customer device to select a vehicle for the ride based on the options. A customer selection is received from the customer device. A vehicle is allocated to the ride based on the customer selection. |

Engine health and life cycle tracking system
An engine-mounted component life cycle data tracking system is provided. The system includes a plurality of RFID tags associated with, positioned proximate to, and configured to transmit and store identification, repair history, and dynamic data regarding a different engine component of a plurality of engine components, wherein the dynamic data includes engine usage, component usage, and/or component fault information. The system further includes an aircraft-mounted controller that includes non-transient computer readable storage media. The controller is configured to: store identification and repair history data retrieved from the RFID tags in the storage media; store dynamic data for the plurality of engine components in the storage media after each engine cycle; and transmit dynamic data to the RFID tags after each engine cycle for storage. After each engine cycle, the aircraft-mounted controller includes in its storage media the identification, repair history and dynamic data for the plurality of engine component. |

Vehicle health record
An example method involves receiving, at a computing system, vehicle diagnostic information from a vehicle. The vehicle diagnostic information may include one or more sets of parameters corresponding to parameter identifiers (PIDs). The method further involves identifying a first set of parameters corresponding to a PID representing a state of a particular system of the vehicle and determining, using the first set of parameters, a current value of the PID. The method may also involve performing a comparison between the current value and a predetermined value for the PID and determining a health of the particular system of the vehicle such that the health reflects a difference between the current value and the predetermined value for the PID. The method may also involve displaying, by the computing system at a graphical interface, a vehicle health record representing the health of the particular system of the vehicle. |

On the fly enrollment for facial recognition
When a software update is provided to a device that implements a facial recognition authentication process, a new authentication algorithm to operate the facial recognition authentication process may be included as part of software update. For a period of time, the new authentication algorithm may operate a “virtual” facial recognition authentication process alongside operation of the existing facial recognition authentication process using the existing (e.g., earlier version) authentication algorithm. The performance of the new authentication algorithm in providing facial recognition authentication (as assessed by the “virtual” process) may be compared to the performance of the existing authentication algorithm in providing facial recognition authentication during the period of time. When the performance of the new authentication algorithm is determined to have a satisfactory performance, operation of the actual facial recognition authentication process on the device may be switched to the new authentication algorithm. |

Automated video verification
A media source is configured to provide a media stream that includes an audio-video recording. A first algorithm detects a presence of synthetic media in a video based on a first feature type. A second algorithm detects the presence of synthetic media based on a second feature type. A device determines that the first feature type is presented in a selected portion of the image frames but the second feature type is not. In response, the first algorithm is executed using the selected portion of the image frames as an input. Based on the executed first algorithm, a probability is determined that the media stream provided by the media source includes synthetic media. |
