Abstract: A communication bus system is provided. The communication bus system includes a communication bus having a plurality of isolatable segments and a bus master coupled to a first end of the communication bus. The bus master is configured to couple to a second end of the communication bus and to decouple from the second end of the communication bus based on a selection signal. A method for operating a communication bus is also disclosed.

Abstract: A bidirectional bus system is provided. The bidirectional bus system includes a plurality of bus slaves configured to couple to a bidirectional bus. Each bus slave of the plurality of bus slaves has a switch operated by a switch control to selectably couple and decouple an upstream portion and a downstream portion of the bidirectional bus relative to the bus slave, with the switch control being powered by activity on the bidirectional bus.

Abstract: A bidirectional bus system that includes a bus master having a first transmitter coupled to a bidirectional bus. The first transmitter transmits a signal in a first voltage range onto the bus. The bus master has a first receiver coupled to the bus. A bus slave having a second transmitter coupled to the bus is included. The second transmitter transmits a signal in a second voltage range onto the bus, where the bus slave having a second receiver is coupled to the bus. The first receiver is configured to interpret the signal in the first voltage range to indicate an idle state while the second receiver interprets the signal in the first voltage range as indicating data. The second receiver interprets the signal in the second voltage range as indicative of an idle state while the first receiver interprets the signal in the second voltage range as indicating data.
