Patent number: 11938932Abstract: Systems and methods for self-driving collision prevention are presented. The system comprises a self-driving vehicle safety system, having one or more sensors in communication with a control system. The control system is configured determine safety fields and instruct the sensors to scan a region corresponding to the safety fields. The control system determines exclusion regions, and omits the exclusion regions from the safety field. The safety system may also include capability reduction parameters that can be used to constrain the drive system of the vehicle, for example, by restricting turning radius and speed in accordance with the safety fields.Type: GrantFiled: June 15, 2022Date of Patent: March 26, 2024Assignee: CLEARPATH ROBOTICS INC.Inventors: Matthew Lord, Ryan Christopher Gariepy, Peiyi Chen, Michael Irvine, Alex Bencz

Publication number: 20220194441Abstract: A system for path control for a mobile unmanned vehicle in an environment is provided. The system includes: a sensor connected to the mobile unmanned vehicle; the mobile unmanned vehicle configured to initiate a first fail-safe routine responsive to detection of an object in a first sensor region adjacent to the sensor; and a processor connected to the mobile unmanned vehicle. The processor is configured to: generate a current path based on a map of the environment; based on the current path, issue velocity commands to cause the mobile unmanned vehicle to execute the current path; responsive to detection of an obstacle in a second sensor region, initiate a second fail-safe routine in the mobile unmanned vehicle to avoid entry of the obstacle into the first sensor region and initiation of the first fail-safe routine.Type: ApplicationFiled: December 2, 2021Publication date: June 23, 2022Inventors: Ryan Christopher Gariepy, Alex Bencz, Yan Ma, Michael Irvine, Shahab Kaynama, James Servos, Peiyi Chen

Patent number: 11287831Abstract: There is provided an electrically-powered material-transport vehicle having a vehicle-charging contact on one side of the vehicle, and a second vehicle-charging contact on the opposite side of the vehicle. The vehicle has a load-bearing cap that covers the top of the vehicle, and a cap elevator for raising and lowering the cap. The cap can be raised and lowered to a transit position, a payload-engagement position, a charging position, and a maintenance position. In the transit position and payload-engagement position, the cap covers the vehicle-charging contacts so that they are not exposed. In the charging position, the cap is raised so that the vehicle-charging contacts are exposed. The vehicle can enter a charging-dock with the cap in the charging position in order to recharge the vehicle's battery.Type: GrantFiled: June 20, 2019Date of Patent: March 29, 2022Assignee: Clearpath Robotics Inc.Inventors: Ryan Christopher Gariepy, Matthew Allen Rendall, John Duncan Edwards, Aaron Wilson, Simon Drexler, Scott Waters, Aaron Gerlach, Mark Podbevsek, Michael Irvine, Vaibhav Kumar Mehta, Peiyi Chen, Amritpal Saini, Robert Dam, Michael O'Driscoll, Arsalan Alim

Patent number: 11103254Abstract: A battery and control module to which a powered surgical tool is releasably attached. Internal to the module there is: a cell for energizing the tool; a sensor for monitoring an operational state of the tool; a sensor for monitoring a trigger external to the module; and a control circuit. Based on the signals output by the sensors, the control circuit selectively applies energization signals from the cell to the power generating unit internal to the surgical tool. In some versions of the invention, the trigger is attached to the module.Type: GrantFiled: August 24, 2018Date of Patent: August 31, 2021Assignee: Stryker CorporationInventor: Michael Irvine

Patent number: 10974585Abstract: A mobile platform for materials transport is provided. The platform includes a pair of suspension devices that in turn include a pair of rocker beams which can be rotated between two positions: a first position where central wheels attached thereto can be used to drive the platform; and a second position where the central wheels are retracted and the platform can be rolled on end wheels without the friction of the central wheels, and an associated drive system, impeding movement of the platform. Furthermore, data from sensors and/or load cells can be used to control movement of the platform; specifically shifts in load distribution and/or sensed forces at the suspension devices can indicate that a load (and/or materials) has shifted and/or is shifting and movement of the platform is adjusted accordingly, for example to prevent the platform and/or the load (and/or materials) from tipping.Type: GrantFiled: March 4, 2020Date of Patent: April 13, 2021Assignee: CLEARPATH ROBOTICS INC.Inventors: Matthew Lord, Roydyn Clayton, Michael Irvine, Ryan Christopher Gariepy

Patent number: 10814891Abstract: Systems and methods for obstacle avoidance with a self-driving vehicle are provided. The system comprises a processor connected to the self-driving vehicle and a sensor in communication with the processor. The sensor is configured to detect objects. The processor is configured to receive a measurement of the self-driving vehicle's speed, and define a sensor region based on the speed. The processor can determine that an object detected by the sensor is within the sensor region, and then initiate a fail-safe routine. The sensor region may be defined based on a range parameter. The sensor region may be defined based on the stopping distance of the vehicle. The sensor region may be redefined when the vehicle's speed changes.Type: GrantFiled: February 27, 2018Date of Patent: October 27, 2020Assignee: CLEARPATH ROBOTICS INC.Inventors: Ryan Christopher Gariepy, Alex Bencz, Yan Ma, Michael Irvine, Shahab Kaynama, James Servos, Peiyi Chen
