A method for improving fire prevention performance of a vehicle-carried data recording device and a protection device thereof are provided, where the method includes: mounting the vehicle-carried data recording device in a water-proof shell in a sealing manner; mounting the water-proof shell in a mounting space enclosed by an upper constant-temperature water shell and a lower constant-temperature water shell; injecting a liquid into the upper constant-temperature water shell and the lower constant-temperature water shell; mounting a constant-temperature water shell composed of the upper constant-temperature water shell and the lower constant-temperature water shell in a fire-proof box; and packing the fire-proof box in a protective housing with heat dissipation holes to prevent a data recording device from being damaged when the vehicle is damaged by the action of an external force. The device is majorly encased by a water-proof shell, a constant-temperature water shell, a fire-proof box and a protective housing successively. The present disclosure has advantages of long fire resistance time and high data security.

An aircraft usage tracking system may include a wireless communications network at a given airport location, and an aircraft usage tracking device carried by an aircraft having at least one motor. The aircraft usage tracking device may include wireless communications circuitry and an aircraft operation controller coupled thereto. The aircraft operation controller may determine a motor start operation of the at least one motor when the aircraft is at the given airport location based upon connection to the wireless communications network, and wirelessly communicate motor start operation data associated with the motor start operation. The aircraft operation controller may determine a motor stop operation of the at least one motor, and determine whether the motor stop operation is at the given airport location based upon a reconnection to the wireless communications network, and when so, wirelessly communicate motor stop operation data associated with the motor stop operation.

The display device is loaded on a vehicle, and connects the communication with the information processing terminal via the connection unit. Specifically, the display device obtains and displays an application image outputted by the information processing terminal. Also, the display device obtains, from the information processing terminal, a property of the application generating the application image. The property of the application may include information whether or not the application is controllable by an external device, the reliability of the application, the genre of the application and the display appropriateness. Then, the display device regulates the display of the application image based on the obtained property of the application and the running state of the vehicle.

A circuit device includes a processing unit that detects occurrence of an internal event of the circuit device, a storage unit, and a clocking unit that generates clocking data which is real-time clock information on the basis of an oscillation signal generated using a resonator. The processing unit stores specific information on the internal event and the clocking data when the occurrence of the internal event is detected, in the storage unit when the occurrence of the internal event is detected.

A method for retrofitting a feature of a vehicle is described, wherein the vehicle is designed for wireless data transmission and is designed for at least one optional feature, wherein the feature can be retrofitted wirelessly. The method comprises the following steps: entering data for identifying a vehicle using an HMI; receiving the data for identifying a vehicle by method of a data processing device and identifying a vehicle in a database; retrieving from the database and outputting via the HMI at least one optionally retrofittable feature of the identified vehicle; selecting at least one feature of the optionally retrofittable features retrieved; acquiring authorization to use the at least one selected feature; transferring data for retrofitting the at least one selected feature to the vehicle; and retrofitting the at least one selected feature during the next commissioning of the vehicle.

A server divides a plurality of vehicles into groups, transmits control information to an on-vehicle information device of individual vehicles belonging to a group to which a processing turn of the transmission process has come, and receives responses indicating presence or absence of abnormality due to update of on-vehicle devices using the control information from the on-vehicle information device of each vehicle. The server performs the transmission process of the control information toward a group having a following turn when responses indicating presence of abnormality are a predetermined reference value or less, and, suspends transmission processes of control information toward groups having following and subsequent turns when the responses indicating presence of abnormality are more than the predetermined reference value.
