A conveyance such as a wheelchair that includes a seat assembly and a chassis. The chassis comprises a central frame member disposed substantially along the centerline of the wheelchair. The central frame member includes portions for connecting to or supporting one or more front casters, a seat assembly, one or more drive wheel assemblies, an energy source (e.g., one or more batteries), rear anti-tip wheels, and/or at least one footplate. The central frame member is disposed substantially along the centerline of the wheelchair and structurally distributes of the weight of the seat assembly (and optionally the weight of the energy source) to the supporting drive wheels and casters. In this manner, a clean- looking, simple, and lightweight chassis structure is provided for a conveyance.

A person moving device for moving a person of limited mobility. The device comprises a lower floor engaging frame part (1) and an upper patient carrying part (6) adapted to carry a patient by engaging the patient's torso from the front and which is mounted to the lower frame part for movement between a patient load-unload position and a patient transport position. The upper patient carrying part being mounted to the lower frame part for curvilinear movement about an axis extending across the patient and positioned so that the patient.s torso moves substantially by rolling about an axis across the device and the patient and substantially about a centre of mass of the patient. A handle (12) is also provided by which a user can cause the upper patient carrying 10 part to move from the load-unload position to the transport position.

A transportation dolly can have a frame, two axles pivotally coupled with the frame, each axle having two distal ends and a wheel assembly coupled at each distal end and a synchronous steering system. The synchronous steering system can include an intermediate link pivotally coupled with the frame, the intermediate link having a two distal ends, and a first push-pull rod coupling one of the two axles with the intermediate link, and a second push-pull rod coupling the other of the two axles with the intermediate link. The first push-pull rod is coupled to one distal end of the intermediate link and the second push-pull rod is coupled to the opposing distal end of the intermediate link. The first push-pull rod, the second push-pull rod, and the intermediate link provide counter phase synchronous pivoting of the two axles relative to the transportation dolly.

One transformable creeper includes three portions. The first portion has a frame, four wheels operatively coupled to the frame such that a lower edge of the frame is maintained above a lowermost point of the four wheels by no more than about two thirds the diameter of the four wheels, and a first support surface operatively coupled to the frame. The second portion has a second frame rotatably coupled to the frame and a second support surface. A lock maintains the second frame at three angles relative to the frame (generally 180°; between about 90° and 180°; and between 0° and 90°). The third portion has a third frame rotatably coupled to the second frame, two wheels, and a third support surface. A lock respectively maintains the third frame at two angles relative to the second frame (generally 180°, and between 0° and 90°).

Embodiments of the present invention provide methods and apparatuses adapted to generate contextualized tokens to facilitate classification of text fragments.

A method and apparatus for an electronic equipment rack that provides mobility through directional self-propulsion and multi-axis suspension. The electronic equipment rack further provides self-powered operation and environmental control with wireless access, while protecting against unauthorized access, electromagnetic interference (EMI), and dust contamination. An alternate embodiment provides a non-mobile electronic equipment rack with multi-axis suspension, while optionally providing wireless access and protection against unauthorized access and the environment.

A shopping cart (10) is provided, suitable for storage and conveyance of a conventional capacity of food or other products while also transporting and entertaining at least one child. The shopping cart has at least one storage basket (12), as well as a body (22) integrally mounted below and forward of the basket. The body simulates a vehicle to provide a relatively easier shopping experience for the guardian and more enjoyable shopping experience for the child. Additional features include use of a swing arm 842) to improve passenger safety, and bumpers (31) to protect the cart and body from collision and abrasion.
