  • Patent number: 11660150
    Abstract: A surgical tool for compact articulating during surgical procedures includes a pitch cable, at least one yaw cable, a first link, a second link, at least one end-effector link, and at least one tensioning mechanism. The first link has a pitch joint end with a pitch joint pin and at least one yaw cable guide channel. The second link has a yaw joint end with a yaw joint pin. The second link is rotatably connected to the pitch joint pin. The at least one end-effector link is rotatably connected to said yaw joint pin. The yaw cables are coupled to the end-effector links such that the yaw cables can actuate the end-effector links about the yaw joint pin. The yaw cable guide channel is configured such that the yaw cables travel through a smooth trajectory to the end-effector links. The tensioning mechanism is configured to maintain a constant length.

  • Patent number: 11540439
    Abstract: A lawn mower includes a seat plate movably coupled to the frame. An operator seat is coupled to the seat plate. An armrest is laterally spaced from the operator seat and includes an elongated support, an arm support surface, and a control panel. The elongated support has a first end fixed to the seat plate and a second end. The arm support surface is coupled to the second end and can support a user's arm. The control panel is positioned between the arm support surface and the second end of the elongated support. The control panel is fixed to the elongated support for movement with the seat plate such that the control panel remains stationary relative to the seat plate. The control panel includes an actuator to control a function of the lawn mower. The actuator is configured to be actuated while the user's arm is on the support surface.

  • Patent number: 7670265
    Abstract: A handle toss training apparatus can be utilized to aid in improving a person's balance, coordination, and skills respective to a maneuver commonly referred to as a handle pass. The handle toss training apparatus includes a balancing board with a base. The base provides a rotational, a rolling, and a pitch motion for the balancing board. A handle is fastened to a wall via a cable. Tension for the handle is created by the specific material used for fabrication of the cable or by a variable weight system.

  • Publication number: 20050146108
    Abstract: A non-torque reactive air suspension exhibiting excellent roll stability characteristics is shown to include frame hangers mounted to frame rails extending longitudinally on opposite sides of a vehicle. Longitudinally extending beams are connected to the frame hangers at one end and extend parallel to the frame rails. At their other ends, the beams are joined by a crossbrace extending laterally across the vehicle centerline. In a central portion thereof, the beams have an axle pivot bore to which an axle clamp assembly is connected, the axle clamp assembly clamping a drive axle housing for the vehicle. The axle pivot bore is generally aligned with the drive axle. A control rod assembly is connected to suspension or frame components. Together with the beams, the control rod assembly forms a parallelogram configuration wherein the beams form the lower linkages of that configuration and the control rods included within the control rod assembly form the upper linkages of that configuration.
