1. Apparatus for remotely monitoring and assessing the location and status of a human subject, the apparatus comprising:

  • a central monitoring device; and

    a portable monitoring unit in communication with the central monitoring device, the portable monitoring unit comprisingat least three automatic sensors associated with and monitoring the condition of the subject, the sensors including a biological condition sensor, an accelerometer, and an audio sensor;

    a portable-unit location-determining device;

    a remotely programmable microprocessor having an active state and an inactive, power conserving state, the microprocessor being in communication with, and receiving sensor signals from, the at least three automatic sensors and in communication with the location-determining device, and being operable to change from the inactive state to the active state in response to an activating parameter for an activation condition selected from the group consisting of a preselected state of at least one of the automatic sensors and a request signal from the central monitoring device;

    a subject status signal input device activatable by the subject and in communication with the microprocessor;

    a first transceiver in communication with the microprocessor, for communicating signals between the microprocessor and the central monitoring device; and

    a power supply connected to provide power to the microprocessor, the first transceiver, and the portable-unit location determining device.
