Patent ID: 7099970

Claim:
An enhanced one-wire bus for the half duplex transmission of serial data between a master and a slave comprising: a translator having a primary interface, a secondary interface, and data storage; a primary one wire bus in electrical communication with said primary interface and with the master; a secondary one wire bus in electrical communication with said secondary interface and the slave device, wherein, when said translator is in a first operational mode, said primary interface is in electrical communication with said secondary interface such that serial data on said primary one wire bus is communicated to said secondary one wire bus, when said translator is in a second operational mode, said primary interface is in electrical communication with said secondary interface such that serial data on said secondary one wire bus is communicated to said primary one wire bus, and when said translator is in a third operational mode, said primary interface is in electrical communication with said secondary interface such that at least a portion of a serial data message transmitted on said secondary bus is replaced by data stored in said data storage as said serial data message is communicated to said primary one wire bus.
