Abstract
A controller that includes a number of switches is associated with a first appliance that has a number of operating states. In at least one of the operating states of the first appliance, the controller responds to certain switch actuations by causing it to perform a task; but when it is in another operating state, the same switch actuations have no meaning insofar as the first appliance is concerned, so the controller responds by transmitting data signals to a second appliance to have it perform a similar task. In this manner, a single controller can be used to control a number of appliances when a particular switch actuation has no meaning in the context of controlling the associated appliance. In an illustrative embodiment of the invention, the keypad of a telephone set is used to select a particular television station. Control signals are sent by the telephone to the television by spread spectrum data transmission over an AC power line. The data transmission format used is in accordance with the CEBUS.RTM. standard promulgated by the Electronic Industries Association.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
