A System and Method for Person or Object Position Location Utilizing Impulse Radio, comprising a plurality of reference impulse radios; an object or person to be tracked having a mobile impulse radio associated therewith; an architecture with an associated positioning algorithm associated with said plurality of impulse radio reference radios and said mobile impulse radio; and display means for displaying the position of the person or object whose position is to be determined.

System and method for person or object position location utilizing impulse radio

A system and method for detecting an impulse radio signal obtains a template pulse train and a received impulse radio signal. The system compares the template pulse train and the received impulse radio signal to obtain a comparison result. The system performs a threshold check on the comparison result. If the comparison result passes the threshold check, the system locks on the received impulse radio signal. The system may also perform a quick check, a sychronization check, and/or a command check of the impulse radio signal.

System for fast lock and acquisition of ultra-wideband signals

A system, electronic monitor and method are provided that utilize the communication capabilities and positioning capabilities of impulse radio technology to enable people (e.g., broadcasters, fans, trainers, jockeys) to track a position of a horse as it moves around a race track and/or to enable people to monitor one or more vital signs of the moving horse. The present invention may also be used track and/or monitor other animals such as dogs and people.

System and method for using impulse radio technology to track and monitor animals

A system, electronic monitor and method are provided that utilize the communication capabilities and positioning capabilities of impulse radio technology to enable people (e.g., mechanics, fans, broadcasters, drivers) to track a position of a vehicle as it moves around a race track and/or to enable people to monitor an engine, transmission system, braking system and other vehicular parameters of the moving vehicle.

System and method for using impulse radio technology to track and monitor vehicles

A system, electronic monitor and method are provided that utilize the capabilities of impulse radio technology to overcome the shortcomings of conventional house arrest monitoring systems. One embodiment of the present invention enables monitoring personnel (e.g., police officers, parole officers) to determine whether a person under house arrest and carrying an electronic monitor stays within their home. Another embodiment of the present invention enables monitoring personnel to determine whether a person under house arrest and carrying an electronic monitor is located within their home and/or also enables monitoring personnel to monitor the vital signs of that person.

System and method using impulse radio technology to track and monitor people under house arrest

A system, apparatus and method are provided that utilize the communication capabilities and positioning capabilities of impulse radio technology to overcome the shortcomings in conventional prison monitoring systems. Basically, the present invention enables prison personnel to track the movements of a prisoner and/or monitor the vital signs of a prisoner using impulse radio technology that is well suited for a prison environment.

System and method for tracking and monitoring prisoners using impulse radio technology

A system, electronic monitor and method are provided that utilize impulse radio technology to enable a farmer to accurately track a position of an object (e.g., farm equipment, farm animal, farm employee) as the object moves around a farm and/or to enable a farmer to monitor a variety of parameters associated with the moving farm equipment. In addition, the system, electronic monitor and method can utilize impulse radio technology to help control either remotely or automatically one or more pieces of farm equipment.

System and method for using impulse radio technology in the farming field

A system, electronic monitor and method are provided that utilize impulse radio technology to alert medical personnel when a patient needs medical assistance. In addition, the present invention includes a system, electronic monitor and method that utilize the communication capabilities and positioning capabilities of impulse radio technology to enable medical personnel to monitor one or more vitals signs of a patient and/or to enable medical personnel to determine a current a position of a patient in a building such as a hospital, nursing home or their home.

System and method using impulse radio technology to track and monitor people needing health care

A software-controlled telephone tester permits untrained consumers to test telephone sets by connecting the line cord to the tester and following simple instructions which are sequentially displayed on a panel. Tests are automatically performed after each instruction to provide objective determinations of the operability of the telephone under test. Tested parameters which fall outside specification result in a failure indication. If the user fails to effect certain instructions properly, a 'try again' instruction is generated. Transmission tests are effected automatically by placing the telephone earpiece and/or mouthpiece adjacent a transducer and transmitting at least one tone from the tester through the telephone and back to the tester. Preferrably a two-tone test is employed using a pair of the standard DTMF signalling tones so that transmission testing is effected using the same circuitry employed for DTMF dial testing. The tester transducer is recessed behind the tester panel to reduce the effect of amplitude variations caused by small positional differences in the placing of the mouthpiece/earpiece adjacent the transducer.
