1. A medical sensing device for detecting a biological parameter, determining a digital representation of the biological parameter, and ultrasonically transmitting the digital representation of the biological parameters as an inaudible sound transmission, the device comprising:

  • a sensor for detecting a biological parameter from a subject;

    a processor configured to receive the biological parameter, determine a representative value from the biological parameter, and digitally encode the representative value as a digital ultrasound signal, wherein the digital ultrasound signal is encoded using a first frequency corresponding to digital zero and a second frequency corresponding to digital 1, wherein the first and second frequencies are each greater than 17 kHz, further wherein the digital ultrasound signal includes a header portion and a data portion; and

    an ultrasonic transducer comprising an ultrasound emitter for transmitting the digital ultrasound signal, wherein the processor is configured to drive the ultrasonic transducer to emit the digital ultrasound signal from the ultrasound emitter.
