Patent ID: 8372018

Claim:
A subject pose determining method comprising: placing a subject onto a surface of a platform, said platform having a first radio-frequency transceiver located at a first location on said surface and a second radio-frequency transceiver located at a second location on said surface, wherein said subject is a human being; placing a first radio-frequency transponder onto an upper extremity of said subject; placing a second radio-frequency transponder onto a lower extremity of said subject; transmitting a first radio-frequency signal from said first radio-frequency transceiver to said first radio-frequency transponder on said upper extremity of said subject, resulting in said first radio-frequency transponder sending a second radio-frequency signal to said first radio-frequency transceiver; transmitting a third radio-frequency signal from said second radio-frequency transceiver to said second radio-frequency transponder on said lower extremity of said subject, resulting in said second radio-frequency transponder sending a fourth radio-frequency signal to said second radio-frequency transceiver; receiving by said first radio-frequency transceiver said second radio-frequency signal; receiving by said second radio-frequency transceiver said fourth radio-frequency signal; and determining a pose of said subject based on said receiving said second radio-frequency signal and said receiving said fourth radio-frequency signal, wherein the method comprises placing radio-frequency transponders onto said subject, and wherein a totality of said transponders consist of the first radio-frequency transponder and the second radio-frequency transponder.
