A system and method for optimizing optical communication for autonomous vehicles, including: determining a predetermined route of a vehicle equipped with an optical communication device (OCD) including an array of micromirrors; determining a location of at least one infrastructure unit along the predetermined route; determining optimal angles for the array of micromirrors based on the predetermined route and the determined location of the at least one infrastructure unit to optimize optical communication between the OCD and the at least one infrastructure unit; and adjusting the array of micromirrors based on the determined optimal angles.

A first group includes first antennas and a first receiver. A second group includes second antennas and a second receiver. Each of the first antennas outputs a first signal according to a first communication form. Each of the second antennas outputs a second signal according to a second communication form. The first receiver receives the first signals individually outputted from the first antennas using a diversity form. The second receiver receives the second signals individually outputted from the second antennas using a diversity form. The multiplexer supplies the multiplex signal obtained by multiplexing the first signal and the second signal to the transmission line. The demultiplexer supplies the first signal and the second signal obtained by demultiplexing the multiplex signal to the first receiver and the second receiver, respectively.

Exemplary embodiments are disclosed of current control circuits and methods of modulating supply current from a first device (e.g., a telematics control unit (TCU), etc.) to one or more second devices (e.g., one or more compensators, etc.). In an exemplary embodiment, a method includes modulating a supply current from a first device to a second device into different current values for reporting different information from the second device to the first device. An exemplary embodiment of a current control circuit includes a variable voltage source electrically coupled with a current source and a current sink. The current control circuit is configured to modulate the supply current from a first device to the second device into different current values for reporting different information from the second device to the first device.

Techniques provided herein are directed toward virtually extending an updated set of output positions of a mobile device determined by a VIO by combining a current set of VIO output positions with one or more previous sets of VIO output positions in such a way that ensure all outputs positions among the various combined sets of output positions are consistent. The combined sets can be used for accurate position determination of the mobile device. Moreover, the position determination further may be based on GNSS measurements.

A communication device is disclosed. The present communication device may include a master including a communication modem, and multiple slaves including antennas. The communication device may execute an artificial intelligence (AI) algorithm and/or a machine learning algorithm, and may communicate with other electronic devices in a 5G communication environment. Therefore, user convenience can be enhanced.

An arrangement has a technical system, in particular a safety-related system, and a control device which controls the system and can change the technical state of the system by use of control commands. An interface device to be connected to the control device is provided. The interface device forms an external interface for connection to an external remote query device. The interface device has a checking device which is configured in such a manner that it checks a received remote query signal for the presence of a query command stored as permissible in the interface device. In the event of permissibility, the interface device forwards only the query command to the control device and blocks the forwarding of the remote query signal as such or all other control commands which are not query commands stored as permissible.

Systems, vehicles, and methods for mobile network communication. A system includes a vehicle configured to be propelled in one or more directions. The system further includes one or more wireless transceivers configured to be coupled to the vehicle and communicate with one or more remote electronic devices. The system further includes a first server configured to communicate with the one or more wireless transceivers and output an action based on an input received from the one or more remote electronic devices. The system further includes one or more second servers configured to communicate with the first server, receive the outputted action, and perform the outputted action.

A user device cradle can include a receiver configured to removably retain a wireless user device. One or more Radio Frequency (RF) signal couplers and one or more power couplers can be disposed in the receiver of the cradle. The one or more RF signal couplers can be configured to couple one or more RF communication signals to the wireless user device, while the one or more power couplers can be configured to couple power to the wireless user device. The coupling of power to the user device can be reduced or minimized when a downlink signal is received by a user device in the user device cradle, or when the user device cradle is in a weak signal area.
