Tracking device
First Claim
1. A monitoring and locating device comprising:
- at least one portable child unit; and
a parent unit in communication with the portable child unit, the parent unit being configured to assign an individual identifier to each portable child unit by wireless radio frequency signal and configured to monitor each of the portable child units by transmitting and receiving signals to each of the portable child units based on the individual identifiers assigned thereto the parent and child units being configured to provide directional information as to a position of the child units with respect to the parent unit and a perimeter alarm when the child unit moves to a distance from the parent unit that is greater than a predetermined distance; and
a directional display coupled to a microprocessor constructed and arranged to display the position of a selected child unit relative to the parent unit based on phase differential signals generated by the microprocessor for the selected child unit; and
an operating channel selection circuit coupled to the microprocessor, the operating channel selection circuit constructed and arranged to select an operating channel on a frequency band for the parent unit to transmit or receive thereon.

Abstract
A monitoring and locating device includes one or more remote child units and a parent unit in communication with each of the child units. The parent unit is adapted to assign and transmit an individual identifier to each child unit. The parent unit is constructed and arranged to continuously monitor each of the child units by transmitting and receiving signals to each of the child units using the individual identifiers assigned thereto. The monitoring and locating device may be used in a method for monitoring and tracking a living entity that includes acquiring the plurality of child units using the parent unit based at least in part on user input. Monitoring each of the plurality of child units individually with the parent unit. Tracking the location of each child unit with the parent unit and locating a selected child unit of the plurality of child units with the parent unit based upon the tracked location thereof.

6. A method for monitoring a plurality of portable transmitters in radio frequency communication with a control unit, the method comprising:
- identifying each portable transmitter, each identifying operation including the control unit assigning and transmitting an individual identifier to each portable transmitter by wireless radio frequency signal, each of the plurality of portable transmitters receiving the individual identifier and sending an acknowledgement signal to the control unit, the control unit receiving each of the acknowledgement signals and activating each of the plurality of portable transmitters for monitoring; and
monitoring the portable transmitter, each monitoring operation includes the control unit selecting an operating channel and sending monitoring commands to each portable transmitter unit and the control unit receiving and monitoring received signals transmitted from each of the plurality of portable transmitter units. - View Dependent Claims (7, 8)
