摘要： A method for serial data transfer in a bus system having at least two bus subscribers that exchange messages via the bus, the transmitted messages having a logical structure according to CAN standard ISO 11898-1, the logical structure encompassing a start of frame bit, arbitration field, control field, data field, CRC field, acknowledge field, and end of frame sequence, the control field encompassing a data length code that contains an information item regarding the length of the data field. The method is characterized in that when a first marker (EDL) is present, the control field of the messages, divergently from ISO 11898-1, encompasses more than six bits; the first marker (EDL) being implemented by way of a recessive bit in the control field, and when the first marker is present, the recessive bit of the first marker (EDL) being followed, in all data messages, by at least one dominant bit.

摘要： This application discusses, among other things, communication apparatus and methods, and more particularly, a single conductor or single wire communication scheme. In an example, a method for communicating between a master device and a slave device using a first single conductor can include transmitting a first ping on the first single conductor using a master device, the first single conductor configured to couple the master device to a slave device, receiving a slave ping on the first single conductor at the master device during a ping interval, toggling a logic level of the first single conductor prior to sending a first data packet using pulses having a duration of less than one half of a unit interval, such as a unit interval associated with a bit interval.

摘要： Embodiments of the present disclosure provide methods for testing channel compliance. The method generally includes identifying at least one design criteria and determining boundary sets of frequency domain parameters for compliant signal channels known to achieve the design criteria. The boundary sets may be used for verifying whether a particular signal channel is compliant by comparing values of frequency domain parameters for the particular channel to one or more of the boundary sets of frequency domain parameters for the known compliant channels.

摘要： Data associated with at least one building condition or status is sensed by one or more sensors. The data from these sensors may be sent over a data bus and received by the central computer. In addition, a modulated signal may be transmitted by one or both of the transmitters across the data bus. The modulated signal is received at the receiver, which analyzes the received modulated signal, and determines whether an intermittent fault has occurred on the data bus based upon the analyzing. For example, the receiver may compare the received signal to an expected pattern and when a discrepancy exists, an intermittent fault is determined to exist. The receiver may also determine the location of the fault based upon the analysis.

An initiator terminal of the present disclosure includes a first wireless unit configured to connect with a target terminal via wireless communication with a first wireless communication method, a second wireless unit configured to connect with the target terminal via wireless communication with a second wireless communication method different from the first wireless communication method, and an access processor configured to execute an access protocol process for remote access to a storage medium that the target terminal includes. If an error occurs during accessing to the storage medium, the access processor switches the access protocol process for remote access to the storage medium between in the wireless communication in the first wireless unit and in the wireless communication in the second wireless unit.

摘要： A method includes determining that a first station has been allocated a first time period to transmit over a shared medium in a network. The method includes transmitting, from the first station to a second station over the shared medium during the first time period, wherein stations other than the first station and the second station refrain from transmitting over the shared medium during the first time period. The method includes receiving, from the second station, a request message to allow the second station to transmit during the first time period and a requested amount of time to transmit. The method includes, in response to allowing the second station to transmit during the first time period, determining an authorized amount of time for the second station to transmit during the first time period, and transmitting an authorization message for the second station to transmit and the authorized amount of time.

摘要： Data communications are effected over one or more network branches to ensure appropriate receipt of data at different devices on the network. In accordance with an example embodiment, time-based communications are effected for a plurality of different network devices, at least two of which are connected to a common wired network link, with each network device being assigned to communicate during different time slots within a communication cycle. Each communication received on the common wired network link is assessed as being error-indicative or not error-indicative. In response to a received communication on the common wired network link being assessed as being error-indicative, the common wired network link is operated to corrupt data received on the branch, such as by driving the branch during a time slot in which the error-indicative communication is received, therein ensuring that other network devices disregard the data received during that time slot.
