Image Number 14 for United States Patent #6839775.

An apparatus for selecting, monitoring, and controlling electrically powered devices is disclosed. In one embodiment, the apparatus includes an electrically powered device having a key operating line and switching control circuitry to control usage of the electrically powered device by interrupting continuity of the key operating line. In another embodiment, the apparatus monitors usage of an electrically powered device. The apparatus includes a circuit which is coupled to the device to provide a power output of the device, an analog to digital converter coupled to receive the power output and convert the same to digital form, and a controller to receive a user input, process the user input by establishing communication with a remotely located device to request approval of a financial transaction, and generate control signals in response to receiving approval. The controller receives the digital form of the power output and monitors the operation of the electrically powered device.
