A vehicle includes a rail-mounted component and a restraint monitoring system. The rail-mounted component can include one or more restraints. The restraint monitoring system includes a restraint control module, an encoder-decoder module, and a rail-mounted component control module. The rail-mounted component control module can include a restraint deployment loop and a restraint diagnostic loop. The restraint deployment loop can include a deployment signal amplifier. The restraint diagnostic loop can include a diagnostic signal amplifier. In examples that include both the deployment signal amplifier and the diagnostic signal amplifier, the deployment signal amplifier and the diagnostic signal amplifier may be wired in parallel.

An automation network provides packet-based communication between the host and a client, wherein the client determines output values from the host in the event of errors in the communication between the host and the client, where the determination of output data can be performed in a separate local processing module in accordance with a less complex method than on the host, such that it becomes possible to perform complex open-loop and closed-loop control tasks on the host even in the case of mobile clients or other clients that are difficult to wire.

In an embodiment a method for operating a processing system includes programming, by a microprocessor during a CAN FD Light data transmission phase, a control register of a Serial Peripheral Interface (SPI) communication interface of the processing system in order to activate a master mode; generating, by the microprocessor during the CAN FD Light data transmission phase, a transmission CAN FD Light frame; storing, by the microprocessor during the CAN FD Light data transmission phase, the transmission CAN FD Light frame to a memory; and activating, by the microprocessor during the CAN FD Light data transmission phase a first DMA channel so that the first DMA channel sequentially transfers the transmission CAN FD Light frame from the memory to a transmission shift register in the SPI communication interface.

Secure serial bus communication methods and devices suitable for automotive applications. An illustrative sensor IC includes: a sensor controller that operates a transducer to obtain measurement data formattable as data packets; a scrambler that masks each data packet with a scrambling operation before that data block is sent via a serial bus to a bus controller device, said scrambling operation having a secret configuration and/or secret initial state; and an integrated circuit component that operates on a seed value to derive the secret configuration and/or secret initial state.

The disclosure relates to a controller and a transceiver and associated software and methods. A controller for communicating with a transceiver in a network node having a first mode of operation and a second mode of operation, the controller comprising: a first-data-terminal for communicating with the transceiver; and a second-data-terminal for communicating with the transceiver, in which the controller is configured to: in the second mode, determine receive-data based on a first-data-signal at the first-data-terminal and a second-data-signal at the second-data-terminal; determine that a change of mode from the second mode to the first mode is required; and in response to determining that a change of mode from the second mode to the first mode is required, provide a controller-mode-signal that instructs the transceiver to operate in the first mode rather than the second mode, wherein the controller-mode-signal is provided by simultaneously driving a first current on the first-data-terminal and a second current on the second-data-terminal.

Systems and methods for side-channel monitoring a local network are disclosed. The methods involve generating a program trace signal from at least one of power consumption, electromagnetic emission, or acoustic emanation of a control processor connected to the local network and operating a monitoring processor to detect a communication of a message on the local network; identify at least one purported control processor related to the communication; analyze the program trace signal of the at least one purported control processor relative to the communication; and at least one of an authenticate or verify one or more purported control processors of the at least one purported control processor based on the program trace signal of the at least one purported control processor.

Embodiments of the invention include a vehicle telematics system that receives different types of identification information from different vehicle modules on the vehicle bus of a vehicle, identifies a vehicle platform based on the identification information by matching the identification information with information stored in a database that has been reverse engineered for a vehicle with a same and/or similar platform and identifies a set of communication data associated with the vehicle platform for communicating with the at least one vehicle module.

A method for an asset tracking system is provided. An example method includes receiving data messages from an asset coupled to the asset tracking system and attempting to obtain asset information from data messages with reference to a local set of signal definitions indicating how data messages received from the asset are to be decoded into asset information. Upon failing to obtain the asset information the asset tracking system requests from an asset data analysis system the generation of a generated signal definition indicating how the data message of the outstanding type is to be obtained from the asset. The asset tracking system provides access to at least one undecoded data message of the outstanding data type to the asset data analysis system, receives the generated signal definition from the asset data analysis system, and adds the generated signal definition to the local set of signal definitions.

A system includes a programmable logic control (PLC) module, an input/output (IO) network bus coupled to the PLC module and provided at facets of a mainframe. A first process chamber attached to a first facet of the facets. A chamber interface IO sub-module is attached to the first facet and coupled to the IO network bus and to a process chamber IO controller of the first process chamber. The chamber interface IO sub-module is to: convert interlock relay signals, received via dry contact exchange with the process chamber IO controller, to digital signals; combine the digital signals into network packets adapted for communication using a protocol of the IO network bus; and transmit the network packets to the PLC module over the IO network bus.

A Controller Area Network (CAN) transceiver includes a receiver configured to determine a voltage differential signal from analog signalling received from a CAN bus and configured to provide a digital output signal at a receiver output to a CAN controller based on the voltage differential signal. The receiver includes arming circuitry configured to place the receiver in an armed or unarmed state based on the voltage differential signal, a first threshold corresponding to a first CAN protocol, and a second threshold corresponding to a second CAN protocol. When the receiver is in the unarmed state, a first digital signal indicative of activity on the CAN bus is provided based on a comparison between the voltage differential signal and the first threshold, and when in the armed state, the first digital signal is provided based on comparisons between the voltage differential signal and each of the first and the second thresholds.
