First Claim
1. An ambulatory monitoring device, comprising:
- a) a battery power source;
b) a sensor powered by the battery and configured for monitoring a physiological signal of a subject;
c) a wireless receiver that uses less than 10 micro-amps of current from the battery power source when operating and is configured to receive wireless communications from a remote device within a first frequency band of a range of frequencies below 1 MHz when the monitoring device is at least 1 meter from the remote device; and
d) a wireless transmitter powered by the battery and that is separate from the receiver,e) wherein after receipt by the receiver of a first wireless communication from the remote device at the first frequency band, the wireless transmitter is configured to transmit a second wireless communication in a second frequency band of a range of frequencies above 10 MHz, and wherein the second wireless communication is of the physiological signal sensed by the sensor.

Abstract
An ambulatory monitoring device includes a sensor to monitor a physiological signal and a battery power source. The device also includes a wireless receiver adapted to monitor a first frequency band having frequencies below 1 MHz and configured to detect and receive, using less than 10 micro-amps of current from the battery power source when operating, wireless communications within the first frequency band from a remote device at least one meter away. The device further includes a wireless transmitter adapted to transmit—after receipt from the remote device of a first wireless communication within the first frequency band that includes an invitation for further communication—a second wireless communication in a second frequency band having frequencies above 10 MHz, the second wireless communication comprising data indicative of the physiological signal as sensed by the sensor.
