Patent ID: 8123684

Claim:
A method for configuring one or more effectors situated within a satellite unit that resides in a subject's body, wherein: the satellite unit includes a number of effectors that interact with the subject's body, and satellite circuitry that is coupled to a bus, and the bus includes first and second conduction paths with at least a portion of the second conduction path being defined through the subject's body when the satellite unit is located within the subject's body, the method comprising: receiving signals over the bus; and based on the signals received over the bus, deriving a relatively stable DC voltage supplying the circuitry, recovering clock and digital data, interpreting bit sequences in the digital data to extract configuration information, using the bit sequences to store configuration information in the satellite unit for the one or more desired effectors associated with the satellite unit, and controlling connection of at least one of the first and second conduction paths of the bus to at least one effector based on the configuration information such that the connection is altered to vary conduction paths.
