Abstract: A Controller Area Network (CAN) transceiver is disclosed. The CAN transceiver includes a CAN bus interface including CANH and CANL inputs, a TXDC interface, RXDC interface and a CAN bus diagnostics module coupled with the CAN bus interface. The CAN bus diagnostics module is configured to analyze the CAN bus interface to detect and error on the CANH and CANL inputs and send a diagnostics code predefined for the detected error to one of the TXDC interface and the RXDC interface.

Abstract: A transceiver configured to send and receive data over a data bus is disclosed. The transceiver includes a communication port to connect to the data bus, a bus idle detector configured to detect when the data bus is idle, a TXDC interface configured to selectively receive and send data and an RXDC interface configured to send data. The transceiver also includes a switch controlled by an output of the bus idle detector. The switch is configured to cause the TXDC interface to be used for sending data out when the bus idle detector detects that the data bus is idle.

Abstract: A circuit for generating a bias voltage for a terminating end capacitor in a controller area network (CAN) bus having a CANH and a CANL terminals is disclosed. The circuit includes a configurable voltage source, a controller to generate a control signal to operate the configurable voltage source, a CANH error detector and a CANL error detector. The CANH error detector and the CANL error detector are configured to provide inputs to the controller. The controller is configured to generate the control signal based on the outputs of the CANH error detector and the CANL error detector. The configurable voltage source is configured to output a bias voltage based on the control signal.

Abstract: Aspects of the present disclosure are directed to assessing characteristics of stored data, as may be implemented for verification thereof. As may be implemented in connection with one or more apparatus or method-based embodiments, a first data signature is generated, which corresponds to a logical derivation of configuration data sent over a data bus. Outputs that correspond to data read out from each of a plurality of configuration registers, which receive the configuration data over the data bus, are logically combined into a second data signature. The first data signature and the second data signature are processed and compared for ascertaining that stored data, as stored in each of the plurality of configuration registers, accurately corresponds to the configuration data sent over the data bus for writing into each of the plurality of configuration registers.

Abstract: The embodiments described herein provide communication devices and methods that can facilitate communication between galvanically isolated systems. Specifically, the embodiments facilitate communication to a galvanically isolated system that is shut down without requiring that this shutdown system consume its own power while it is shutdown. To facilitate this, the communication devices and methods provide a wake-up device on the side of the shutdown system and facilitate the transfer of power across the galvanic isolation to the wake-up device when communication to the shutdown system is needed. With the wake-up device powered using power that was transferred across the galvanic isolation, the wake-up device can perform the actions needed to wake up the shutdown system, and can thus facilitate communication between the galvanically isolated systems. Thus, communication between galvanically isolated systems is facilitated without requiring that the shutdown system consume its own power during shutdown periods.

Abstract: The disclosure relates to a processing module and associated method for calibrating an object-detection system for a vehicle comprising a plurality of object-detection sensors. The method comprises receiving, from each of a plurality of the object-detection sensors, a value associated with the detection of a marker; and determining a position of each of the object-detection sensors with respect to the vehicle based on the received values associated with the detection of the marker.
