Publication number: 20220194699Abstract: A logistics tower includes a vertical storage cell column, a vertical retrieval system and a horizontal shuttle system. The vertical storage cell column includes an elevator shaft extending therethrough and a plurality of storage modules arranged around the elevator shaft. The vertical retrieval system includes a winch and a robotic bin handier. The robotic bin handler is moveably by the winch within the elevator shaft of the vertical storage cell column. The robotic bin handler includes a carnage assembly that extends inwardly and outwardly therefrom to access and retrieve storage bins from the storage modules arranged around the elevator shaft. The carriage assembly includes a gripping assembly that selectively couples and decouples the storage bin to the carriage of the robotic bin handler. The vertical retrieval system lowers the storage bin coupled to the carriage assembly to a. robotic shuttle situated on the horizontal shuttle system.Type: ApplicationFiled: April 9, 2020Publication date: June 23, 2022Inventors: ADAM LOOKER, JONATHAN LIN, STEVEN LECKENBY, LINCOLN CAVALIERI, PAUL SANDIN

Patent number: 10486480Abstract: A convertible trailer for road and rail operation has four rail wheels and two road wheels. Each road wheel is within a road wheel assembly which connects to a main pivot or axle on the trailer, around which the entire assembly can rotate and thereby separating the road wheels from direct connection to the trailer. A lift, which may be motorized or hand controlled, raises and lowers the entire trailer by raising or lowering a foot which engages with the ground. When raised sufficiently and a locking mechanism disengaged, the road wheel assemblies may pivot on the pivot or axle. This pivoting allows the wheels to be locked in high position out of the way for rail operation. With the road wheels disengaged, the trailer may be lowered allowing the rail wheels to contact rails for railway operation.Type: GrantFiled: June 16, 2017Date of Patent: November 26, 2019Assignee: RailPod, Inc.Inventors: Brendan English, Paul Sandin, James Forte

Patent number: 9950716Abstract: An autonomous device for rail track inspection includes a drive wheel system propelling the device via a drive wheel system, an automatic track loading fixture for and applying a load on rails, and sensors for taking track gauge measurement. Different automatic track loading fixtures may require stopping for load and measurement, or loading and measuring while still in motion. A switch agnostic system for operation with devices on a conventional railroad track system includes a linear slider movably mounted along a linear sliding support; multiple sensors mounted to the linear slider, the sensors operable to identify a rail of a track junction; and multiple roller bearings operable to engage the rail of the track junction and control the device across the track junction in response to movement of the linear slider along the linear sliding support.Type: GrantFiled: June 30, 2015Date of Patent: April 24, 2018Inventors: Brendan English, Paul Sandin, Blair Morad, Shawn Dooley, Craig Thrall

Publication number: 20170267264Abstract: This invention utilizes two sensing technologies in combination with or in isolation of an automated inspection vehicle to conduct inspections of internal rail flaws in steel railroad track. A vehicle equipped with X-radiation sensing is used as a secondary method to assess the deviations in magnetic fields that are sensed by a primary sensor consisting of a single or multiple magnetometers. The magnetometers sense changes in magnetic field that are correlated to the flaws inside the steel rail. The combination of technologies improves the probability to detect railroad flaws and offers the ability to accurately track and monitor flaws.Type: ApplicationFiled: March 21, 2017Publication date: September 21, 2017Inventors: Brendan English, Paul Sandin, Wesley Kriener, Sam Dahlberg, Stephen Imsong
