    摘要: One or more systems, methods, or computer program products can include receiving an echo data set including information representative of an echo sensed by a transducer, provided at least in part by one or more actual targets included in a region of interest. The region of interest can be modeled, including selecting or generating an array manifold matrix including information corresponding to any one or more candidate targets. The weights of the candidate targets can be determined using the array manifold matrix and the echo data set, including minimizing an argument of a function modeling the weights of the candidate targets. In an example, the echo data set can be dithered, such as by adding a specified dithering signal.

    摘要: 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.

    摘要: 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.
