Patent number: 9805579Abstract: This disclosure provides a method and system for extending the capability of a proximity detection system that is based on use of low frequency magnetic fields, to avoid conflicts in crowded work sites. The improvement is attained by combining the advantages of these low frequency magnetic fields with the advantages of much higher frequency, radiated (RF) signals that are controlled to be produced at the same time, concurrent with each other, in a coordinated and/or synchronous manner.Type: GrantFiled: July 13, 2015Date of Patent: October 31, 2017Assignee: Strata Safety Products, LLCInventor: Larry D.

Patent number: 9761143Abstract: Collision avoidance systems and methods. In some embodiments the collision avoidance systems may include a magnetic field generator for generating a low frequency oscillating magnetic field, and a magnetic field detector, wherein the system is configured to determine a relative speed between the magnetic field generator and the detector using magnetic speed pings generated by the magnetic field generator. In other embodiments, the methods may include generating a low frequency oscillating magnetic field from a magnetic field generator, detecting the magnetic field from a magnetic field detector, and determining a relative speed between the magnetic field generator and the detector using magnetic speed pings generated by the magnetic field generator.Type: GrantFiled: August 31, 2015Date of Patent: September 12, 2017Assignee: Strata Safety Products, LLCInventors: Tom Michaud, Michael Berube, Brian Dunkin, David Hakins, Dwayne Towery, Gary Herda

Patent number: 9466216Abstract: The invention relates to a complex proximity safety and warning system. The invention provides a safety system comprising a generator that generates a magnetic field that establishes a boundary, where the generator is capable of receiving radio frequency signals. Also provided is a radio frequency device that sends radio frequency signals, the radio frequency device being capable of sensing the magnetic field and generating a radio frequency response. In the safety system, the generator generates the magnetic field for a first predefined time period, and thereafter senses for a radio frequency response signal from the radio frequency device within a second predefined time period. The invention also provides for shaping safety zones by overlaying magnetic field boundaries to produce a different boundary. The invention also provides for varying the strength of magnetic fields by adjusting a width of a timed pulse.Type: GrantFiled: September 5, 2014Date of Patent: October 11, 2016Assignee: Strata Safety Products, LLCInventors: Larry D.
