A hand truck that weighs less than twenty-three kilograms (23 kg) when unloaded. The hand truck has a platform with wheels, which permits the platform to travel along a beam while reducing the chances of seizing as objects are loaded on or unloaded from the hand truck. The hand truck also has a strut pulley sub-assembly that controls the rate of travel of the platform along the beam.

A rack-mounted information handling system (IHS) includes a rack to mount functional compute components between opposing lateral sides that are being supported by floor supports. A pair of rack lifting structures are each respectively positioned beside a different opposing lateral side of the rack. Each rack lifting structure includes a foot having at least front and rear floor contacting portions. A vertical support includes a lower portion that is coupled to the foot and an upper portion that extends above an adjacent top lateral frame member of the rack. A top member is coupled to the vertical support and presents front and rear attachment components to engage the adjacent top lateral frame member. A jack engagement surface is defined within the vertical support to receive one or more furniture jacks that can be used to lift the pair of rack lifting structures and the attached rack-mounted IHS.

A retention mechanism for retaining an agricultural machine in engagement with a fork assembly. The mechanism may be provided on the fork assembly, agricultural machine or split between them. The retention mechanism may be actuated by a foot associated with either the fork assembly or the agricultural machine. The retention mechanism may employ pivoting latches or a clamping mechanism that clamps upon the forks or tines.

The safety barrier is for a lift platform that moves between a bottom position and an upper position and safety barrier includes a gate, defining a first plane. The gate includes a surface adapted to engage a cam assembly. The safety barrier has a mount that mounts to the lift platform and a mounting pin, defining an axis, that rotatably mounts the gate. The safety barrier also includes an upright post assembly having an upright post mounted to a non-movable surface, and the cam assembly that applies an upward force to the surface of the gate. When the lift platform moves to the bottom position, the assembly engages the surface and the gate rotates about the axis in the first plane into an open position, and when the lift platform moves to the upper position, the gate rotates about the axis in the first plane into a closed position.

A moving system comprising a master controller for monitoring and controlling a master operation comprising one or more individual movers such that each mover arrives at predefined end point at selected times. Each mover includes a mover control system that interacts with the master controller and has a predefined virtual vector path with one or more defined end points. The predefined virtual vector path comprises a plurality of discrete points, wherein each discrete point has a vector axis for use by the master controller and the mover control system to direct the mover to move such that it arrives at each defined end point at a selected time. In operation, the master controller functions to modify the predefined virtual path and sends commands to the mover control system in response to changes in the master operations.

A lifting system for lifting and/or lowering loads having a lifting apparatus which is suitable for conveying loads along a lifting direction from a first transfer position into a second transfer position and along a lowering direction from the second transfer position to the first transfer position, and a conveyor apparatus which is suitable for taking on, at the first and/or the second transfer position, the loads conveyed by the lifting apparatus. The conveyor apparatus has at least one holding pendulum which is pivotable into a holding position, wherein the lifting apparatus has at least one holding receptacle for the holding pendulum, wherein the holding pendulum, in the holding position, can be placed in engagement with the holding receptacle, by a movement of the holding receptacle in the lowering direction, such that a movement of the lifting apparatus in the lowering direction is blocked, and/or the holding pendulum, in the holding position, can be placed in engagement with the holding receptacle, by a movement of the holding receptacle in the lifting direction, in such a way that a movement of the lifting apparatus in the lifting direction is blocked. The holding receptacle has a first guide track, wherein the first guide track is designed so as, during a movement of the holding receptacle along the lifting direction or the lowering direction, to move the holding pendulum into a first position in which the holding pendulum cannot be placed in engagement with the holding receptacle.

Examples relate to simultaneous localization and calibration. An example implementation may involve receiving sensor data indicative of markers detected by a sensor on a vehicle located at vehicle poses within an environment, and determining a pose graph representing the vehicle poses and the markers. For instance, the pose graph may include edges associated with a cost function representing a distance measurement between matching marker detections at different vehicle poses. The distance measurement may incorporate the different vehicle poses and a sensor pose on the vehicle. The implementation may further involve determining a sensor pose transform representing the sensor pose on the vehicle that optimizes the cost function associated with the edges in the pose graph, and providing the sensor pose transform. In further examples, motion model parameters of the vehicle may be optimized as part of a graph-based system as well or instead of sensor calibration.

Example implementations may relate methods and systems for detecting, recognizing, and localizing pallets. For instance, a computing system may receive sensor data representing aspects of an environment, and identify a set of edge points in the sensor data. The computing system may further determine a set of line segments from the set of edge points where each line segment may fit to a subset of the set of edge points. Additionally, the computing system may also filter the set of line segments to exclude line segments that have a length outside a height range and a width range associated with dimensions of a pallet template, and identify, from the filtered set of line segments, a subset of line segments that align with the pallet template. Based on the identified subset of line segments, the computing system may determine a pose of a pallet in the environment.
