Powered patient support apparatuses—such as beds, cots, stretchers, or the like—include a plurality of user controls that allow a caregiver to control the steering and/or driving of one or more powered wheels from multiple different locations around the patient support apparatus (e.g. head end, foot end, and/or the sides). The control is carried out by force sensors that detect both an orientation of the applied forces and a magnitude of the applied forces. Translational and/or rotational movement is effectuated, depending upon the magnitude and direction of the forces, as well as the physical location of the applied force relative to a reference point on the support apparatus, such as the center. One or more object sensors may also be included in the support apparatus to assist in steering and/or navigating.

A walk power mower having a cutting deck supported upon the ground by a front and rear wheel(s). The mower includes a traction drive system incorporating a bidirectional transmission adapted to propel the mower alternatively in both forward and reverse directions. In some embodiments, the mower may include a single bidirectional transmission (e.g., powering only rear wheel(s) or only front wheel(s) of the mower), while in other embodiments, two bidirectional transmissions may be provided to power both the front and the rear wheel(s). In other embodiments, the mower may include a bidirectional transmission powering the rear wheel(s), while the front wheel(s) may be attached to the deck via a caster assembly.

A motorized wheelbarrow assembly for includes a wheelbarrow that has a pair of handles and a wheel rotatably coupled between the pair of handles. The wheel may roll along a support surface. A drive unit is coupled to the wheelbarrow. The drive unit is in mechanical communication with the wheel. The drive unit selectively rotates the wheel to urge the wheelbarrow along the support surface.

The tracked stroller frame device may allow a user to take a stroller with them when camping, hiking, or otherwise travelling over rough terrain. The device implements a continuous track system for providing additional tractive area and reducing or eliminating getting stuck on uneven surfaces, and may include a motorized mechanism for providing driving force. The tracked stroller device allows a user to take a baby or young child with them without carrying the baby or young child. The device may be collapsible for ease of storage and transporting and may incorporate a storage area to allow for transporting of other items. A braking system may also be implemented to slow down the device or keep it parked.

A replacement mobility assembly for a walk-behind, powered device (10) may include first and second drivable components, a mobility assembly frame, and an adaptation assembly. The powered device may be provided with an original mobility assembly (40) that is to be removed from coupling with a drive assembly and a chassis (15) of the powered device prior to installation of the replacement mobility assembly. The first and second drivable components may each be of a different type than corresponding drivable components of the original mobility assembly. The first and second drivable components may be operably coupled to the mobility assembly frame. The adaptation assembly may be configured to enable the mobility assembly frame to be operably coupled to the chassis and the first and second drivable components to be operably coupled to the drive assembly.

The compact pulling apparatus includes a watertight elongated housing extending along a longitudinal axis and a track disposed around the housing along its longitudinal axis. The track enables the apparatus to move when rotatably driven around the housing. Depending on the implementation, the apparatus can include a generator/motor to selectively produce electricity which can power external equipment and rotatably drive the track, and/or a fuel-power engine. The apparatus further includes a power train assembly by which the rotating output power is transmitted from inside to outside the housing by the power train assembly using at least one rotatable shaft section sealingly extending across a corresponding one of the walls of the housing.
