  • Bus system comprising a feed module and a load module
    Patent number: 10469285
    Abstract: A bus system comprises a data line having a first channel with a first pair of wires and a second channel with a second pair of wires. The first channel connects a physical feed module interface to a physical consumer module interface and a first DC voltage source to a first consumer module DC voltage consumer, to transmit a first differential data signal between the feed module interface and the consumer module interface and a first direct current from the first DC voltage source to the first consumer module DC voltage consumer. The second channel connects the feed module interface to the consumer module interface and a second DC voltage source to a second consumer module DC voltage consumer, to transmit a second differential data signal between the feed module interface and the consumer module interface and a second direct current from the second DC voltage source to the second consumer module DC voltage consumer.

  • Range extension for combined data and power line
    Patent number: 10333640
    Abstract: An apparatus and a method for range extension for a combined data and power line are provided. Further, a bus system is provided. The design is based on a supply voltage that is transmitted via the combined data and power line being refreshed by a charge pump. Further, there may be provision, by way of example, for a data signal that is transmitted via the combined data and power line to be refreshed using the likewise transmitted supply voltage.

  • RANGE EXTENSION FOR COMBINED DATA AND POWER LINE
    Publication number: 20180013504
    Abstract: An apparatus and a method for range extension for a combined data and power line are provided. Further, a bus system is provided. The design is based on a supply voltage that is transmitted via the combined data and power line being refreshed by a charge pump. Further, there may be provision, by way of example, for a data signal that is transmitted via the combined data and power line to be re-freshed using the likewise transmitted supply voltage.
