<description><![CDATA[A dual mode motion sensor for detecting both motion of a moving target and a range of the moving target. The dual mode motion sensor normally operates in a pulse transmission mode. If motion is detected, the sensor automatically switches to a frequency modulated continuous wave transmission mode. This will allow the sensor to determine the range of the moving target. The sensor includes a microcontroller that compares the determined range of the moving target with a predetermined maximum detection range. If the determined range is outside or exceeds the predetermined maximum detection range the sensor will ignore the motion. If the determined range is within the predetermined maximum detection range, an alarm will be generated.]]></description>

<description><![CDATA[Chronologically synchronizing a unique positing signal generated by a positioning-unit device at a known location with a reference positioning signal generated by a reference transmitter at a known geometric distance. The positioning-unit device receives and interprets a reference positioning signal. It then generates and transmits a unique positioning signal, wherein the unique positioning signal is aligned with a frequency steerable clock. The positioning-unit device then receives the unique positioning signal. The positioning-unit device then adjusts the frequency of the frequency steerable clock by an amount derived from a measured frequency difference. The positioning-unit device then determines a reference positioning signal propagation delay between the reference transmitter and the positioning-unit device. At this stage, a time difference is measured between the received reference positioning signal and the received unique positioning signal. Finally, the frequency steerable clock is offset for a period of time derived from the measured time difference and the determined propagation delay and the unique positioning signal is consequently adjusted.]]></description>
