An electronic pallet (e-pallet) includes a superstructure mounted to a wheeled base platform. A tether device defines an articulation angle with respect to a leading edge of the superstructure, and is grasped by an operator towing the e-pallet. A motor connected to driven road wheels transmits a drive torque to the road wheels responsive to motor control signals, including a desired yaw rate and ground speed. A speed sensor, angle sensor, and length sensor are respectively configured to determine an actual ground speed of the e-pallet, the articulation angle, and a length of the tether device. An electronic controller, in response to the input signals, generates the motor control signals using proportional-integral-derivative (PID) control logic. Coupled lateral and longitudinal dynamics control loops respectively determine the desired yaw rate and ground speed to accommodate for motion of the operator.

A method of manufacturing a window may include cutting a window having a uniform thickness of about 20 μm to about 100 μm and polishing a cut surface of the window with a polishing pad having an elastic modulus less than an elastic modulus of the window while applying slurry to the cut surface of the window.

A platform including a top deck is configured to receive a pallet when stacked thereon. The top deck includes at least one integrally formed recessed support configured to receive a pallet support of the pallet. The at least one recessed support includes a perimeter recessed in the top deck and which defines a cavity configured to receive the pallet support.

A rack system movable by a forklift having blades that can be selectively raised and lowered. The rack system includes a rack and a hitch device for connecting the forklift to the rack. The rack includes a structure configured for supporting and transporting materials, at least one wheel located at a first end of the structure, and a hitch bracket located at a second end of the structure. The hitch device includes a body configured to be carried by the blades of the forklift, and an arm pivotably secured to the body, and an engagement member at the second end of the arm. Upward movement of the blades raises the engagement member into engagement with the hitch bracket so that further upward movement of the blades raises the second end of the rack and horizontal movement of the forklift rolls the rack on the at least one wheel.

A pallet comprising at least three upper carrier plates (3) and at least three carrier supports (5), in which the bottom of each upper carrier plate (3) is provided with first snapping portions (11) in an array manner, the top of each carrier support (5) is provided with first snapping grooves (4), and the upper carrier plates (3) are snapped with the first snapping grooves (4) on the top of the carrier supports (5) through the first snapping portions (11), and which reduces space occupation and facilitates storage and transportation.

A cage can be positioned around a medical balloon, such as an angioplasty balloon, to assist in a medical procedure. The cage can include a plurality of strips, each extending between a set of rings including first and second rings. As the balloon expands, the first and second rings move closer together and allow the strips to expand outward. The cage may have wedge dissectors on the strips.
