Abstract: A controlling device location determination system and method. A controlling device such as a remote control has programming for transmitting a signal response to a plurality of control environments, each environment including a signaling device. Each signaling device in receipt of the signal request sends a signal response having a unique ID (associated with location definitions relating to the environment from which he signaling device is located) which is chosen to be characteristically attenuated by the surroundings of the environment (i.e., IR signals in a room). Because the controlling device can only be in one environment at a given time, and given the attenuation characteristics of the signal response from each signaling device, only one signal response will be received by the controlling device in each environment.

Abstract: A controlling device having a feature for toggling between various device mode states. The device mode state toggle feature may be implemented as a key which is preferably located with the function keys thus being spaced from the top of the controlling device. The device mode state toggle feature may be used to sequentially toggle between all device mode states of the controlling device, to toggle between a currently selected device mode state and a previously selected device mode state of the controlling device, to toggle between device mode states that have been designated by a user of the controlling device, etc. An indicia, such as a LED, key illumination, color, sound, or the like, may be utilized to provide an indication to the user as to which device mode state the controlling device is placed into when the device mode state toggle feature is activated.

Abstract: A method for determining a power source voltage level of a power source in a system in which the power source is connected to a microcontroller. A charging circuit is in direct communication with a pin of the microcontroller and the power source voltage level is determined by charging the charging circuit using a constant voltage level and determining a time when the charging circuit attains a voltage level sufficient to transition the pin of the microcontroller from a state corresponding to a logic “0” to a state corresponding to a logic “1.” The determined time and a predetermined relationship between the power source voltage level and an input port transition voltage value of the microcontroller is then used to determine the power source voltage level of the power source.

Abstract: A data system includes a secured appliance capable of receiving broadcast programming and a remote control used to transmit data frames to the secured appliance. The secured appliance is provided with a decryption key that is complimentary to an encryption key provided to the remote control. The encryption key is used to encrypt at least a part of a data frame transmitted by the remote control to the secured appliance, the data frame including data for commanding an operation of the secured appliance. The remote control cannot be used to command certain operations of the secured appliance until such time as the decryption key is supplied to the secured appliance thus effectively limiting the ability to use the secured appliance to access the broadcast programming.
