Abstract: A method and system for facilitating command of a group determines a present rank protocol associated with users of an ad hoc wireless communication network. The method includes identifying at a first wireless device a second wireless device in operative communication with the first wireless device (step 805). A physical parameter measured at the first wireless device is then compared with a physical parameter measured at the second wireless device and wirelessly received at the first wireless device (step 810). A base rank of a user of the first wireless device is then compared with a base rank of a user of the second wireless device (step 815). A present rank of the user of the first wireless device is then determined relative to a present rank of the user of the second wireless device based on comparisons of the physical parameters and the base ranks (step 820).

Abstract: A method and system for monitoring physiological parameters is useful for remote auscultation of the heart and lungs. The system includes an acoustic sensor (105) that has a stethoscopic cup (305). A membrane (325) is positioned adjacent to a first end of the stethoscopic cup (305), and an impedance matching element (335) is positioned adjacent to the membrane (325). The element (335) provides for acoustic impedance matching with a body such as a human torso. A microphone (315) is positioned near the other end of the stethoscopic cup (305) so as to detect sounds from the body. A signal-conditioning module (110) is then operatively connected to the acoustic sensor (105), and a wireless transceiver (115) is operatively connected to the signal-conditioning module (110). Auscultation can then occur at a remote facility that receives signals sent from the transceiver (115).
