  • Patent number: 11726491
    Abstract: A material handling vehicle guidance system comprises a first conductive member, a second conductive member, and an electrical current source. The second conductive member is electrically coupled to the first conductive member and extends parallel to the first conductive member to define a loop. The first conductive member and second conductive member are coupled to a shielded cable connector. The electrical current source supplies current to the first conductive member in a first direction and supplies current to the second conductive member in a second direction opposite the first direction to produce a narrowcast radio frequency signal detectable between the first conductive member and the second member.

  • Publication number: 20210327300
    Abstract: Systems and methods for material handling vehicle simulation are provided. In one aspect, a method for material handling vehicle simulation using a material handling vehicle includes connecting a simulation controller to a simulation port, providing an input to a soft switch on a touch screen, upon providing the input to the soft switch on the touch screen, triggering the material handing vehicle to transition from the standard mode to the simulation mode, and projecting a simulated environment onto a simulation display. The simulated environment is configured to simulate operation of the material handling vehicle on the simulation display.

  • Patent number: 11087639
    Abstract: Systems and methods for material handling vehicle simulation are provided. In one aspect, a material handling vehicle simulation system includes a material handling vehicle having a plurality of controls operable to manipulate the material handling vehicle to perform a desired operation, and a vehicle controller configured to selectively transition between a standard mode where the vehicle controller is configured to instruct the vehicle to perform standard operating tasks and a simulation mode. The material handling simulation system further includes a simulation kit having a simulation display, and a simulation controller in communication with the plurality of controls and the simulation display. When the vehicle controller is in the simulation mode, the simulation controller is configured to simulate operation of the material handling vehicle on the simulation display in response to manipulation of at least one of the plurality of controls.
