    Abstract: An interactive system is provided in which information is displayed in response to the entry of the digits of a channel number. The interactive system may be implemented on a television, a computer, or a radio system. The displayed information may be program listings information such as the channel designator or the program currently airing on the channel. The displayed information may also be a list of channels. The list of channels may be associated with the entered digits, may be component channels, or channels of the same type and may be sorted by various techniques such as numerically, by favorite channels, by type, etc. The interactive system may allow a user to specify a source identifier to channels from different sources and display the channels with the source identifier when they are entered.

    Abstract: The present invention determines the resonant frequency of a sensor by adjusting the phase and frequency of an energizing signal until the frequency of the energizing signal matches the resonant frequency of the sensor. The system energizes the sensor with a low duty cycle, gated burst of RF energy having a predetermined frequency or set of frequencies and a predetermined amplitude. The energizing signal is coupled to the sensor via magnetic coupling and induces a current in the sensor which oscillates at the resonant frequency of the sensor. The system receives the ring down response of the sensor via magnetic coupling and determines the resonant frequency of the sensor, which is used to calculate the measured physical parameter. The system uses a pair of phase locked loops to adjust the phase and the frequency of the energizing signal.

    Abstract: A coupling loop or antenna is provided that can be used with a system that determines the resonant frequency of a sensor by adjusting the phase and frequency of an energizing signal until the frequency of the energizing signal matches the resonant frequency of the sensor. In one embodiment multiple energizing loops energize an implanted sensor and a sensor coupling loop connected to an input impedance that is at least two times greater than the inductance of the sensor coupling loop receives the sensor signal.
