Abstract: Surgical table comprising: a base comprising a chassis and rotatably connected to the chassis a plurality of wheels for supporting the surgical table on a floor, a first of the wheels being drivable and comprised in a swivel castor rotatably connected to the chassis; a column extending from the chassis; a tabletop coupled to the column and providing a patient support surface; and a drive system for causing rotation of the first wheel relative to the chassis thereby to drive the surgical table along the floor. Also disclosed are surgical tables with a drive system for causing rotation of a wheel of the table in dependence on one or more of a state of a dead man's switch of the table, a height of a column of the table, a state of a brake of the table, and a state of a power supply of the table.

Abstract: Methods and systems for an energy efficient MTRS are provided. In one embodiment, a refrigerated transport unit is provided that includes a multi-zone transport unit and an energy efficient MTRS. The multi-zone transport unit includes an internal space separated into a first zone and a second zone. The internal space includes a zone separator separating and thermally isolating the first zone and the second zone. The energy efficient MTRS is configured to control and maintain a separate environmental condition requirement of each of the first zone and the second zone. The energy efficient MTRS includes a remote fan unit provided between the first zone and the second zone. The remote fan unit is configured to provide a heat exchange between the first zone and the second zone for providing climate control within the second zone.

Abstract: Disclosed are a cold-charging type truck box/cargo container and a temperature-keeping box, which includes a truck box that includes one or more temperature-keeping chambers and a cold storage chamber arranged to correspond to a top of the temperature-keeping chambers, the cold storage chamber receiving therein one or more cold accumulators, wherein a wall of the truck box corresponding to the cold storage chamber is provided with a connector; and a freezer, which includes a delivery tube and a freezing system, the delivery tube having a first end connected to the freezing system, the delivery tube having a second connected to a fast connector; wherein connection is selectively made between the connector and the fast connector to allow the freezing system to supply cold energy through the delivery tube into the cold storage chamber to freeze the cold accumulators. With freezing of the cold accumulators being completed at every morning, cargos can be transported from a transfer station to a destination.

Abstract: A machine, such as a mobile asset, vehicle, or agricultural vehicle, includes a chassis, an adjustment system, and a wheel. The adjustment system replaces a conventional non-extendable leg connected between the chassis and the wheel of the machine. The adjustment system can extend and withdraw in length, such that the height of the machine can vary as needed.

Abstract: A door installation system for safely installing or removing a heavy door by a single person. The door installation system generally includes a base, a vertical member extending from the base in an upward manner, a brace member extending between the base and the vertical member, a guide structure attached to the upper portion of the vertical member for guiding an upper portion of a door, and a carriage removably attachable to the base. The carriage is capable of adjusting the attitude of a door being installed to fit within a door jamb. The vertical member and the base are pivotally connected to one another to allow for folding into a compact structure.

Abstract: The disclosed articulated wheel assemblies and associated vehicles, for example wheelchairs, include articulated wheel assemblies with at least one offset connecting arm rotatably attached at one end to a payload platform, for example a seat, and attached at the other end to a linear actuator, where the linear actuator is further connected to a wheel. Embodiments include a rotary actuator for varying the linear actuator swing angle, a rotary actuator for eccentrically rotating a hubless wheel, a linear actuator motor for varying the length of the linear actuator, and a propulsion motor. Embodiments provide omnidirectional motion, stepping action when presented with obstacles, irregular surface negotiation, tight space maneuvering and other features to provide disabled people increased mobility. Alternate embodiments include a payload platform with a support strut, which is rotatably attached to an offset connecting arm and pivotally mounted to a seat.

Abstract: A sled device for permitting transportation of a person and cargo over a variety of surfaces includes a sled including a bottom wall and a perimeter wall that extends upwardly from the bottom wall to define a receiving space of the sled to receive the person and cargo. The bottom wall is slidable along a soft support surface. A front wheel assembly is rotatably coupled to the sled and is rotatable between a deployed position and a stowed position. The front wheel assembly engages and rolls along a hard support surface when the front wheel assembly is in the deployed position. A plurality of rear wheel assemblies is pivotally coupled to the sled and each is pivotable between a lowered position and a raised position. The rear wheel assemblies engage and roll along the hard support surface when the rear wheel assemblies are in the lowered position.

Abstract: A portable transportation assembly 10 having a pair of wheels 40, 42 which may be selectively raised and lowered and which is adapted to transport a bathroom assembly 200 in an easy and efficient manner.

Abstract: An adjustable eccentric axle caster assembly for a pallet truck is provided. The adjustable caster assembly includes an eccentric axle, a caster wheel mounted on the eccentric axle, and a fastener for securing the eccentric axle to provide a desired caster wheel position. Additionally, a method of adjusting the eccentric axle caster assembly is provided.
