A sensing and displaying system is provided including a sensor unit having a transducer disposed in intimate contact with a vessel. The transducer senses a characteristic within the vessel like pressure and outputs electrical signal representative thereof. The sensor unit further includes a response signal generator which transmit a signal representative of the characteristic. A receiver unit receives the transmitted signal and converts it to visual indicia of the characteristic, for example, a number on a liquid crystal display. The system is capable of two-way communication between the sensor unit and the receiver unit. Both the sensor unit and receiver unit store transmitted data in internal memory.

[ What is claimed is:] [29.] A method for communicating between a sensor and a receiver in a remote detect and display system using a carrier wave, the sensor being spatially separate from the receiver, said method comprising the steps of:sending an activation signal having at least one pulse of the carrier wave from the receiver to the sensor;sending first pulses of the carrier wave to the sensor for initiating transmission of first data by the sensor;receiving a first signal from the sensor indicative of the first data;sending the carrier wave to the sensor for enabling the sensor to read second data;sending the activation signal from the receiver to the sensor;sending second pulses of the carrier wave to the sensor for initiating transmission of the second data; andreceiving a second signal from the sensor indicative of the second data.
