The described techniques address the issues of latency and lengthy processing times associated with conventional redundant sensor measurement systems that rely upon digital transmission protocols by implementing a diverse analog sensor interface architecture. The described architecture may advantageously use a number of sensor measurement paths that may be independent of one another or share any suitable number of common components to provide varying levels of redundancy. The analog interfaces may provide signal diversity with respect to the use of different types of analog transmission protocols, which may include different signaling interfaces (e.g. differential versus single-ended), different transmission interfaces (e.g. voltage versus current interfaces), and/or the use of different signalization schemes.

The present invention relates to an integrated circuit device for controlling LIN slave nodes based on a control signal transmitted by a LIN master control device. The IC device comprises a slave node circuit for processing the control signal when received in the form of a LIN message frame via a first data line terminal. The IC device also comprises a master node circuit for processing further control signals to be transmitted in the form of LIN message frames via a second data line terminal to the LIN slave nodes. The IC device also comprises a processing unit for controlling the LIN slave nodes based on the control signal by composing the further control signals.

An electronic controller of a restraint control system for a vehicle comprises an electronic control unit including a first serial interface. The electronic controller also comprises a communications controller including a second serial interface and a plurality of PSI5 (Peripheral Sensor Interface 5) digital communications interfaces. Each of the first and second serial interfaces are Serial Peripheral Interfaces (SPI) in direct communications with one another, and the digital communications interfaces are each configured to communicate with a remote sensor. The communications controller is configured to transmit a voltage sync pulse to each of the remote sensors via the PSI5 digital communications interfaces in response to a synchronization command received from the electronic control unit via the serial interconnection. The voltage sync pulses on each of the PSI5 interfaces may be staggered and non-overlapping to reduce EMI production and to reduce the current load of the electronic controller.

A data collection method and apparatus, a Modbus system, and a storage medium, and pertain to the field of communication technologies. In embodiments, one or more pieces of block data are collected at one-time interaction between a master and a slave, and a maximum amount of data carried in each piece of block data is 256. In the Modbus system, one piece of data is represented in a minimum of 1 byte, so that the data carried in each piece of block data can be up to 256 bytes. If a plurality of pieces of block data are collected at one-time interaction, an amount of data that can be collected is much larger than 252 bytes limited in a protocol. That is, in the embodiments, a larger amount of data can be collected at one-time interaction.

A network node for coupling to a communication bus, the node comprising: a receiver configured to receive messages from the communication bus; and a transmitter configured to transmit first messages having a first message format and configured to transmit diagnosis messages having a second message format on the communication bus for use in determination of communication errors, wherein said transmitter is configured to send said one or more diagnosis messages having one or more of: (i) a predetermined pattern of symbols; (ii) a predetermined sending schedule; (iii) a predetermined line encoding method; (iv) a predetermined bit rate; (v) a predetermined position in one or more of the first messages; (vi) a predetermined signalling frequency that is out of a frequency band used for transmission of the first messages; and (vii) a predetermined signal strength different from the signal strength used to send the first messages.

Disclosed embodiments relate, generally, to improved data reception handling at a physical layer (PHY). Some embodiments relate to end of line systems that include legacy media access control (MAC) and PHY that implement improved data reception handling disclosed herein. The improved data reception handling improves the operation of the end of line systems, and the MAC more specifically, and in some cases to comply with media access tuning protocols implemented at the physical layer.

A device for a serial bus system. The device has a receiver receiving a signal from a bus of the bus system. For a message exchanged between user stations of the bus system, a recessive bus state is overwritable by a dominant bus state and the recessive bus state is generated differently in the first communication phase than in the second communication phase. The receiver generates a digital signal based on the received signal, and the signal being output to a communication control unit for evaluating the data contained in the digital signal. The receiver uses a first and second reception threshold for generating the digital signal in the second communication phase, the second reception threshold having a voltage value lower than that of the first reception threshold or higher than the highest voltage value which, during normal operation, is established on the bus for a dominant bus.

A vehicle communication system for use in a vehicle having a vehicle bus. The vehicle communication system includes a display unit, a processing unit, and a relay device. The display unit provides a display screen and a receiver for receiving messages from the processing unit to be displayed on the display screen. Further, the processing unit, having means for voice recognition and dictation, includes a transmitter for sending messages to the receiver and a plurality of controls for selecting and inputting the desired message. The relay device is in electrical communication with the vehicle bus for receiving information as to the brakes, turn signals, and transmission of the vehicle, wherein the relay device powers the display unit when the transmission of the vehicle is started and displays a predetermined message on the display screen when the brakes and turn signals are engaged. The processing unit can further be operated via a remote device.

An envelope tracking (ET) amplifier apparatus is provided. The ET amplifier apparatus includes an ET integrated circuit (ETIC) and a distributed ETIC (DETIC) coupled to a single-wire bus that correspond to a first bus access priority and a second bus access priority, respectively. The ETIC and the DETIC can contend for access to the single-wire bus by asserting a bus contention indication(s) when the single-wire bus is in a defined bus state configured to permit bus contention. In a non-limiting example, a winner for the single-wire bus is a peer device having a highest bus access priority between the ETIC and the DETIC. In this regard, each of the ETIC and the DETIC can have a chance to initiate communications over the single-wire bus, thus making it possible for the single-wire bus to function based on bidirectional peer-to-peer (P2P) bus architecture capable of supporting more application and/or deployment scenarios.

The shield device is configured to direct CAN Flexible Data-rate (FD) traffic received from the CAN bus interface to the security module.
