An overlap detection unit for a user station of a serial bus system. The overlap detection unit includes a collision detection block for detecting bus states on a bus of the bus system, in which, in order to transmit a message, bus states of user stations of the bus system are generated on the bus with a first physical layer in a first communication phase, and are generated with a second physical layer in a second communication phase, the second physical layer being different from the first physical layer. The collision detection block generates a signal whose value indicates whether or not the bus states in the second communication phase have a level that corresponds to an overlap of the first and second physical layers or an overlap of two second physical layers, and the collision detection block is designed to output the signal for the user station.

A method of communication between an Ethernet Media Access Controller (MAC) and a physical interface (PHY) is disclosed. The method includes establishing communication between the MAC and the PHY via a first serial link in accordance with a Serializer Deserializer (SERDES) protocol. In a data transfer mode, data is transferred along the first serial link. Idle frames are transferred within an idle time gap along the link in an idle mode. The PHY is managed by encoding Management Data Input/Output (MDIO) information in one or more MDIO frames, and transferring the one or more MDIO frames within the idle time gap along the first serial link.

A device for a serial bus system. The device includes a receiver for receiving a signal from a bus of the bus system, in which bus system at least one first communication phase and one second communication phase are used for exchanging messages between user stations of the bus system. For a message, the bus states of the signal received from the bus in the first communication phase are different from bus states of the signal received in the second communication phase. The receiver is designed to generate a digital signal from the signal received from the bus and to output the signal to a communication control device which evaluates data contained in the digital signal. The receiver uses a first reception threshold and a second reception threshold in each of the communication phases for generating the digital signal, and the second reception threshold has a negative voltage value.

Disclosed is a vehicle system including: a first electronic device configured to receive a radio frequency (RF) signal from an external device and process the RF signal to generate data; and a second electronic device configured to receive the data through an Ethernet communication method and perform an operation based on the data, wherein the first electronic device includes: a first signal detector configured to receive a first wake-up signal in a power saving mode state; and a first Ethernet interface configured to attempt an Ethernet connection with the second electronic device when the first signal detector receives the first wakeup signal.

Full-duplex communications over a single-wire bus is described in the present disclosure. In embodiments disclosed herein, a master circuit and a slave circuit(s) are able to communicate forward (master to slave) bus telegrams and reverse (slave to master) bus telegrams concurrently over a single-wire bus consisting of one wire. Specifically, the master circuit is configured to modulate the forward bus telegrams based on voltage pulse-width modulation (PWM), while the slave circuit(s) is configured to modulate the reverse bus telegrams based on current variations. In addition, the slave circuit(s) is further configured to harvest power from the master circuit concurrent to receiving the forward bus telegrams and sending the reverse bus telegrams. By supporting full-duplex communications over the single-wire bus, it is possible to improve efficiency, cost, and power consumption in an electronic device wherein the single-wire bus is deployed.

Calibration of devices communicating on a shared data bus may improve data integrity on the shared data bus by reducing duty cycle distortion. Duty cycle distortion may be reduced by adjusting timing of a transceiver in a device for communicating on the shared data bus using calibration codes. The calibration codes may be loaded into memory and used to reconfigure the transceiver timing on the shared data bus with reconfiguration occurring within one or more unit-intervals of time. The calibration code may be used, for example, to adjust a PMOS or NMOS trim circuit at the transceiver.

A load drive system includes a communication bus; a controller; and a driver. The controller has a CAN transceiver and a CAN controller that transmit an instruction message instructing a drive state of a solenoid of an automatic transmission via the communication bus. The driver has (i) a CAN transceiver and a CAN controller that receive the instruction message via the communication bus, and (ii) a drive circuit that drives the solenoid according to the received instruction message. The controller transmits a first periodic message in a first cycle and a second periodic message in a second cycle, respectively as the instruction message.

An electrical connector includes: an upper and lower terminal modules each including plural terminals; a metallic plate secured between the upper and lower modules; a metallic bracket accommodating the secured metallic plate and upper and lower terminal modules; and an insulative body insert-molding the metallic bracket with the secured metallic plate and upper and lower terminal modules to form a tongue exposing the terminals of each of the upper and lower terminal modules. The metallic bracket contacts the metallic plate and borders the tongue.

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.

Systems, methods, circuits and computer-readable mediums for a network message translator are disclosed. In an embodiment, a device includes a host processor and a translator. The host processor is configured to process messages and the translator is operable to: receive a first message from the host processor, the first message having a first frame format that is associated with a data time window; translate the first message into a first translated message having a second frame format such that the first translated message includes additional bits based on the second frame format; and sending the first translated message on a bus based on the second frame format such that the first translated message is sent on the bus during the data time window.
