International Classification:

G08B 21/00

US Classification:

34053913, 3405731, 367118, 702150

Abstract:

A locator system for use in connection with at least one mobile person includes a mobile locator system adapted to be worn by the person, wherein the mobile locator system includes an inertial navigation system. The locator system further includes a reference locator system to provide information about a position of the mobile locator device relative to a coordinate system. In several embodiments, the reference locator system comprises an ultrasonic system. For example, the reference locator system can include at least one ultrasonic transmitter and at least one ultrasonic receiver. One of the at least one ultrasonic receiver and the at least one ultrasonic transmitter can be positioned at a known position on the coordinate system and the other of the at least one ultrasonic receiver and the at least one ultrasonic transmitter can be worn by the person. The reference locator system can also include a plurality of ultrasonic transmitters and a plurality of ultrasonic receivers. Each of the plurality of ultrasonic receivers or each of the plurality of ultrasonic transmitters can be positioned at known positions on the coordinate system.

Abstract:

A locator system to be associated with a mobile person includes a receiver to receive ultra-wide bandwidth signals and a transmitter to transmit ultra-wide bandwidth signals. The transmitter is adapted to transmit ultra-wide bandwidth signals, and the receiver is adapted to receive ultra-wide bandwidth signals from at least one other locator system. The other locator system includes a receiver to receive ultra-wide bandwidth signals and a transmitter to transmit ultra-wide bandwidth signals. The locator system and the at least one other locator system provide a distance between the locator system and the at least one other locator system so that the locator system can be located without establishing a reference ultra-wide bandwidth locator system. The locator system can be adapted to be in a low-power mode until activated upon communication of an activation signal to the locator system. A safety system is adapted to be associated with a mobile person and includes a locator system including a receiver to receive ultra-wide bandwidth signals and a transmitter to transmit ultra-wide bandwidth signals. The safety system further includes a telemetric communication system adapted to communicate telemetric data and sensor system including at least one sensor adapted to measure at least one parameter. The locator system is adapted to be in a low-power mode until activated upon communication of an activation signal to the locator system. The locator system transmits ultra-wide bandwidth signals periodically and receives periodic ultra-wide bandwidth signals from at least one other like locator system upon activation.

Abstract:

A personal navigation system, including: at least one inertial sensor module associated with a user, the inertial sensor module comprising at least one sensor to generate location data associated with the user; a communication device to receive and/or transmit at least a portion of the location data; and an onsite computer to communicate with the communication device and receive at least a portion of the location data; wherein at least one of the inertial sensor module and the onsite computer is configured to determine at least one activity of the user based at least in part upon the location data; wherein the onsite computer is programmed to configure a display including a representation of the user based at least in part upon the location data; wherein at least one of the determination and the configuration is performed substantially in real-time.
