  • Patent number: 11938063
    Abstract: A patient support apparatus includes a litter that includes a support structure articulable between seated and supine configurations. The support structure includes a seat section and a leg section coupled to the seat section and articulable relative to the seat section around a seat axis between first and second angular positions corresponding to the seated and supine configurations, respectively. The apparatus includes a steerable wheel assembly coupled to and rotatable relative to the leg section around a steering axis, and a wheel system including a deployment frame coupled to and rotatable relative to the leg section around a pivot axis and a wheel coupled to and rotatable relative to the deployment frame around a wheel axis parallel to the seat axis. The apparatus includes a wheel deployment mechanism configured to rotate the deployment frame around the pivot axis when the leg section articulates between the first and second angular positions.

  • Publication number: 20240059352
    Abstract: An articulated work machine with individually powered drive members. Each drive member is controlled by a corresponding electric motor, and is capable of rotating at a different speed and in the opposite rotational direction than all other drive members. Each drive member may also remain stationary while all other drive members rotate. The electric motors are commanded by a controller, which may be directed by inputs from by an operator. A lift arm extends from the front end of the vehicle, and a platform station extends from the rear end of the vehicle. The lift arm is connected to a tool, such as a bucket.

  • Patent number: 11767656
    Abstract: A cruise control system for work machines. The system comprises one or more levers for controlling the velocity of the work machine and one or more magnet assemblies. The magnet assemblies comprise means of overcoming the neutral bias of a control lever so that the velocity of the work machine may be maintained without manual input from the operator. The magnets may act directly upon a control lever or a surface adjacent a control lever. Additional controls may be employed to set a maximum cruising speed for the work machine when cruise control is engaged.

  • Publication number: 20230203788
    Abstract: A hydraulic control system for use with a work machine. The work machine has a platform which supports an operator. When the operator is not on the platform, the platform moves into a first position, causing a signal generator to send a signal to a controller. The controller is configured to limit the hydraulic flow to the ground drive motor when the platform is in the first position. The controller may directly reduce operation of the engine, or may adjust a valve which diverts a portion of hydraulic flow. The limitation may be overridden when desired by the operator.
