Patent ID: 8419627

Claim:
A medical system comprising: a wireless transmitting medical apparatus including a transmitting unit that generates a modulated signal containing a broadband signal component and a narrowband signal component, and that transmits the modulated signal to the outside the wireless medical apparatus; and a receiving device that receives the modulated signal via at least three receiving antennas, the receiving device including a signal processing system that processes the broadband signal component contained in the modulated signal; and a received-strength detecting system that processes the narrowband signal component contained in the modulated signal, wherein data about the narrowband signal component processed by the received-strength detecting system is used to detect a position of the wireless transmitting medical apparatus; the wireless transmitting medical apparatus includes a signal processing unit that generates a transmission signal having a signal section containing a specific signal with a fixed frequency and a data section containing in-vivo data about a subject; and a modulator that performs digital modulation on the transmission signal, and generates the modulated signal containing the narrowband signal component corresponding to the specific signal in the signal section; the signal processing unit generates the transmission signal containing the specific signal that is a direct current signal in the signal section and the in-vivo data in the data section, and the modulator performs the digital modulation on the transmission signal generated by the signal processing unit, and generates the modulated signal containing the narrowband signal component that is a carrier frequency component in the signal section.
