Patent number: 10344444Abstract: An edge protection safety bund system (10) for use in connection with a rock bund made of rock fill. The edge protection safety bund system (10) comprises a bund module (12) having a barrier wall (14) and a base plate (16). The bund module (12) is preferably one of a plurality of bund modules (12) arranged side by side to form an extended barrier wall (14). The barrier wall (14) of each module (12) extends substantially perpendicularly upwards from the base plate (16), and a support web (18) extends at an angle from a rear face of the barrier wall (14) to an upper surface of the base plate (16). In use, when rock fill is dumped onto the rear of the bund modules (12), and allowed to flow back to its natural angle of repose behind the barrier walls (14), it creates a rock bund (20) with a front face formed by the extended barrier wall (14).Type: GrantFiled: June 30, 2015Date of Patent: July 9, 2019Assignee: Hiram (WA) Pty LtdInventors: Steven Peter Durkin, John Forbes Murdoch

Patent number: 9933514Abstract: LADAR systems and methods are disclosed. LADAR systems include a LADAR transmitter configured to emit a laser signal from a platform and a LADAR receiver configured to detect the laser signal returning from a target moving relative to the platform. The LADAR receiver includes a dynamic receiver filter with a receiver bandwidth (which may be about equal to the linewidth of the laser signal) and a tunable receiver center wavelength. The LADAR receiver is configured to adjust the receiver center wavelength to a wavelength that is Doppler-shifted due to the target velocity. Methods include transmitting a laser signal from a platform, returning the laser signal from a moving target, adjusting a dynamic receiver filter to a receiver center wavelength that is based upon the center wavelength of the returned laser signal (that includes a Doppler offset due to the relative velocity of the target), and receiving the returned laser signal.Type: GrantFiled: March 12, 2015Date of Patent: April 3, 2018Assignee: The Boeing CompanyInventors: Vytas Thomas Gylys, Michael C. Cates, Richard A. Niksch, Paul J. Rodney, Peter Durkin

Patent number: 8177028Abstract: A ladderway system for an underground raise includes an elongate tube adapted to generally conform to the shape of the raise. The tube is of circular cross-section to generally conform to the shape of a round bored raise. The tube is formed with a longitudinal slit along its entire length, whereby the diameter of the tube can be adjusted to generally conform to the shape of the raise. The ladderway system further includes a ladder adapted to be mechanically coupled to an interior of the tube. The tube is manufactured of a sufficiently rigid and strong plastics material, such as polyurethane, so that it acts as a surface membrane or liner within the raise.Type: GrantFiled: December 2, 2005Date of Patent: May 15, 2012Assignee: Bortana Pty. Ltd.Inventor: Steven Peter Durkin
