The present disclosure relates to a control module circuit having a circuit communication input port, a circuit communication output port, a first controllable unit that has a first controller module, and a second controllable unit having a second controller module. The first controller module has a first communication input port connected with the circuit communication input port and a first communication output port. The second controller module has a second communication input port connected with the first communication output port and a second communication output port connected with the circuit communication output port. The first and second controllable units are adapted to be identified with a permanent identity by way of a transmittable data signal receivable at the communication input port and sequentially received by the first and second controllable units.

An on-board update device and an on-board update system provided herein may prevent a decrease in the electric power charged in the battery caused by an update. An on-board update device has an update processing unit configured to update a program stored in a storage unit of a communication device. The on-board update device includes: an update information acquisition unit; a required electric power estimation unit; and a battery level acquisition unit acquires an amount of electric power charged in the battery. The update processing unit performs an update process in consideration of the amount of electric power estimated by the required electric power estimation unit, the amount of electric power acquired by the battery level acquisition unit, and a priority level of the update program or data acquired by the update information acquisition unit.

A method is described. The method includes associating an identity to a computing device based on a context measurement. The method also includes generating a network address for the computing device based on the associated identity. The context measurement may include a biometric measurement and the network address of the computing device may be a function of the biometric measurement.

The present disclosure relates to a communication ID allocation method and system of a battery management module. The system according to the present disclosure includes a first to nth battery management modules sequentially connected through a communication interface, wherein each battery management module designates itself as a master module or a slave module depending on whether or not a pulse signal is received from a battery management module at a higher level, and each battery management module allocates its communication ID according to a pulse width of the pulse signal received from the battery management module at a higher level, generates a pulse signal having the pulse width corresponding to the communication ID of the battery management module at a lower level, and outputs the generated pulse signal to the battery management module at a lower level.

BUS system, method of operating a BUS system, and fluidic system with a BUS system, the BUS system comprising a multitude of users. Information regarding an allocation feature is transmitted to the users of the BUS system by other users of a group of users of the BUS system and by the respective users themselves.

A network hub is provided for an onboard network system. The onboard network system includes first and second networks for transmission of first-type and second-type frames following first and second communication protocols. The network hub includes a receiver that receives a first-type frame. A processor determines whether or not the first-type frame received by the receiver includes first information that is a base for a second-type frame to be transmitted to the second network, to obtain a determination result, and selects a port to send a frame based on the first-type frame based on the determination result. A transmitter sends the frame based on the first-type frame to a wired transmission path connected to the port selected by the processor based on the first-type frame received by the receiver.

Embodiments of Vehicle-to-everything (V2X) communications authentication are described. In some embodiments, a user equipment (UE) configured V2X communication and configured to operate within a fifth-generation system (5GS) and/or a combined 5GS and fourth-generation system (4GS) can encode a V2X capability indication in a request message for transmission to a network entity, such as a Access and Mobility Management Function (AMF). The V2X capability indication can indicate a capability of the UE for V2X communication over a PC5 reference point, and the request message can further include an indication of a Radio Access Technology (RAT). In some embodiments, the AMF can determine whether the UE is authorized to use the V2X communications over the PC5 reference point, and whether the UE is authorized to use the RAT indicated in the request message. Accordingly, the AMF can transmit a V2X services authorization to a next generation radio access network (NG-RAN).

It is provided to implement a different number of logical slaves in a field device for use in an AS interface network as a function of the assigned address, which slaves may be addressed using the assigned address in the standard or in the expanded addressing mode. Thus, in a field device, it is possible to provide slaves having different profiles, via which different data types may be exchanged. Furthermore, a method is provided, with which a field device having different slaves is able to be addressed in a simple manner while avoiding double addressing.

A system for decoding an unknown automotive controller area network (CAN) message definitions. CAN data vehicle signal mappings are typically held in secret and varied by automotive model and year. Without knowledge of the mappings, the wealth of real-time vehicle data hidden in the automotive CAN packets is uninterpretableimpeding research, after-market tuning, efficiency and performance monitoring, fault diagnosis, and privacy-related technologies. This system can ascertain the CAN signals' boundaries (start bit and length), endianness (byte ordering), signedness (binary-to-integer encoding) from raw CAN data. This allows conversion of CAN data to time series. Interpreting the translated CAN data's physical meaning and finding a linear mapping to standard units (e.g., knowing the signal is speed and scaling values to represent units of miles per hour) can be achieved for many signals by leveraging diagnostic standards to obtain real-time measurements of in-vehicle systems. The system can be integrated into lightweight hardware enabling an OBD-II plugin for real-time in-vehicle CAN decoding or run on standard computers. The system can output a standard DBC file with the signal definition information.
