A control portion (10) of a network equipment (1) attempts, when connected to other equipment, connection by using a predetermined communication parameter through communication portions (11, 12), and in a case that the communication is not established, the control portion (10) executes negotiation and establishes communication with the other equipment by using an agreed communication parameter.

A device has a plurality of CAN XL communication systems, a bus, and a switching circuit. The bus has a transmission node and reception node, and receives from each CAN XL communication system a respective second transmission signal and drives the logic level at the transmission node as a function of the logic levels of the second transmission signals, and provides to each CAN XL communication system a respective second reception signal having a logic level determined as a function of the logic level at the reception node. The switching circuit supports a plurality of modes. In a first mode, the switching circuit is configured to provide the NRZ encoded transmission signals of the CAN XL communication systems as the second transmission signals to the bus system, and provide the respective second reception signal received from the bus to the CAN XL protocol controllers of the CAN XL communication system.

Apparatuses, methods, and computer-readable media are provided for operating a port manager to detect a first link condition or a second link condition of a circuitry. Under the first link condition, a first link between a downstream port of the circuitry and an upstream port of a switch is compatible to a first protocol, and a second link between a downstream port of the switch and an upstream port of a device is compatible to the second protocol. Under the second link condition, the first link exists and is compatible to the first protocol, while there is no second link being compatible to the second protocol. The port manager is to operate the downstream port of the circuitry according to the second protocol on detection of the first link condition, or according to the first protocol on detection of the second link condition. Other embodiments may be described and/or claimed.

A bus driving device includes at least three high-side output drivers and at least three low-side output drivers. A part of the high-side output drivers and a part of the low-side output drivers are alternately coupled in series, and the remains of the high-side output drivers and the low-side output drivers are alternately coupled in series. The part of the high-side output drivers and the part of the low-side output drivers receive an input digital signal and sequentially drive a first supply bus and a second supply bus based on the input digital signal, and the remains of the high-side output drivers and the low-side output drivers receive the inverted input digital signal and sequentially drive the first supply bus and the second supply bus based on the inverted input digital signal.

A marine vessel maneuvering system includes an operator, propulsion device controllers each configured or programmed to control driving of a respective propulsion device based on an operation signal from the operator, a first communication bus to transmit the operation signal to some of the propulsion device controllers, a second communication bus to transmit the operation signal to a remainder of the propulsion device controllers excluding the some of the propulsion device controllers, and a gateway device to connect the first communication bus to the second communication bus such that the first communication bus and the second communication bus communicate with each other.

A frame transmission prevention apparatus connected to a network of a network system including a plurality of electronic control units communicating with one another via the network is provided. The apparatus includes a processor and a memory. The memory includes at least one set of instructions that causes the processor to perform processes when executed by the processor. The processes include receiving a first frame from the network and switching whether to perform a first process for preventing transmission of the first frame on the basis of management information indicating whether prevention of transmission of a frame is permitted if the first frame satisfies a first condition.

A method for checking a message in a communication system, in which multiple users are connected to a communication medium that includes two signal lines and exchange messages via same. A time difference between points in time of reception of a message that is sent on the communication medium is ascertained at two different, predefined positions on the communication medium, and based on a comparison of the time difference to at least one reference time difference, it is determined whether the message originates from a verified user. During the ascertainment of the time difference at the two positions, in each case a difference signal is formed from signals that have resulted on the two signal lines due to the message.

An example Smart Candle Platform is configured to includes a candle fixture that comprises an outer shell having an opening, a mid-frame, and a base, and a fuel bottle configured to hold a fuel material and is removably coupled to the candle fixture. The fuel bottle is positioned at least partially within a hollow interior of the mid-frame of the candle fixture and accommodated by the base. The fuel bottle further comprises a wick that extends through an opening of the outer shell, and the candle fixture includes an ignitor configured to ignite the fuel material via the wick to produce a living flame. The candle fixture further includes an inner cover having one or more reinforcement ribs configured to provide structural support for the one or more ignitors.

An intersection traffic control method, apparatus and system are provided. The method includes that: a vehicle signal of a first vehicle at an intersection and a vehicle signal of a second vehicle located in a set zone in proximity to the intersection are acquired; the vehicle signal of the first vehicle and the vehicle signal of the second vehicle are input into an instruction learning model trained in advance based on a reinforcement learning principle, and a score of a preset traffic indicator of the first vehicle after executing a respective candidate action instruction is calculated; a reward of the first vehicle when executing the respective candidate action instruction is acquired according to the score of the preset traffic indicator, a candidate action instruction corresponding to a maximum reward is determined as an output result of the instruction learning model, and a next action instruction is determined according to the output result; and navigation of the first vehicle through the intersection is controlled according to the next action instruction.

A utility vehicle that includes a vehicle control system having one or more real time clocks (RTC). The RTC can be embedded in the vehicle control system, or in components or subsystems of the vehicle control system, and can be either dedicated electronics or software based. Information provided by the RTC can be used to synchronize components and subsystems of the vehicle control system. Further, such inclusion of the RTC can enable the vehicle control system to initiate a number of time based functions, including, for example, time based functions relating to battery charging, wake-up and shut down of components, status reporting, periodic vehicle level events and maintenance, and management of time based operation or use of the utility vehicle or components thereof, including vehicle cameras.
