Abstract
An asset, object, person or animal monitoring system and associated method for monitoring assets, objects, people or animals utilizing impulse radio techniques. The asset, object, person or animal monitoring system of the present invention can vary the duty cycles of the impulse radio transmitters, by both manual and automatic means, to adapt to varied requirements.
Claims12
A method of impulse radio duty cycle variation and synchronization for an impulse radio asset, object, person or animal monitoring system, comprising:
- synchronizing an internal clock means associated with an impulse radio transmitter to a timing means;
- synchronizing an internal clock means associated with an impulse radio receiver to a timing means corresponding to said timing means used to synchronize said impulse radio transmitter;
- transmitting impulse radio transmissions at a predetermined time, said predetermined time being determined by said internal clock associated with said impulse radio transmitter;
- and
- listening by said impulse radio receiver for said impulse radio transmissions at a time corresponding to said predetermined transmission times of said impulse radio transmitter.
A method of impulse radio duty cycle variation and synchronization for an impulse radio asset, object, person or animal monitoring system including at least two impulse radio transmitters, comprising:
- receiving an impulse radio transmission, said impulse radio transmission containing information about which impulse radio transmitter is transmitting;
- and
- listening for subsequent impulse radio transmissions according to predetermined transmission intervals associated with said impulse radio transmitter.
A method of impulse radio duty cycle variation and synchronization for an impulse radio asset, object, person or animal monitoring system, comprising:
- transmitting impulse radio transmissions at least once during a predetermined interval;
- listening for impulse radio transmissions at least during a time interval corresponding to the impulse radio transmission interval.
An apparatus for impulse radio duty cycle variation and synchronization for an impulse radio asset, object, person or animal monitoring system, comprising:
- an internal clock synchronizing means associated with an impulse radio transmitter, said internal clock synchronizing means synchronizing said impulse radio transmitter to a timing means, said impulse radio transmitter transmits impulse radio transmissions at a predetermined time, said predetermined time being determined by said internal clock associated with said impulse radio transmitter;
- and
- an internal clock synchronizing means associated with an impulse radio receiver, said internal clock synchronizing means synchronizing said impulse radio receiver to a timing means corresponding to said timing means used to synchronize said impulse radio transmitter, said impulse radio receiver listens for said impulse radio transmissions at a time corresponding to said predetermined transmission times of said impulse radio transmitter.
An apparatus for impulse radio duty cycle variation and synchronization for an impulse radio asset, object, person or animal monitoring system, comprising:
- an impulse radio transmitter, said impulse radio transmitter transmits impulse radio transmissions at least once during a predetermined interval;
- an impulse radio receiver, said impulse radio receiver listens for impulse radio transmissions at least during the interval corresponding to the impulse radio transmission interval.
