Abstract: Various implementations include implants and related methods for moving bone. Certain implementations include an implant for moving bone in a patient's body, the implant including: an implantable biocompatible housing having a first cavity; a first adjustment rod at least partially contained within the first cavity; and a drive mechanism configured to drive the first adjustment rod to enable both translation axially relative to the housing and rotation about a primary axis of the housing.

Abstract: A system for insulating a railcar is disclosed. The system includes a roof, front, back, left, and right side portions. Each portion includes a plurality of insulating panels. The insulating panels are coupled to an inner surface of the railcar. The insulating panels are joined to each other by a plurality of joints. Each insulating panel includes an outer layer with a first material and a first thickness, an insulating layer with a second material and a second thickness, and an inner layer with a third material and a third thickness. Each of the first and the third material comprises a fiberglass reinforced plastic or a vinyl. The second material comprises a foam or a fibrous material. The insulating layer is positioned between the inner layer and the outer layer. The inner layer has one or more spacings to house one or more bars with a fourth material, comprising steel.

Abstract: A sheet for writing or drawing thereon includes a sheet of paper sized no greater than four inches by six inches, and having a plurality of lines printed on a surface thereof. The lines are positioned and spaced to form a plurality of squares of equal size covering the surface of the sheet. In another embodiment, a sheet includes a rectangular sheet of paper sized approximately eight and one-half by eleven inches and perforated to form first, second, third, fourth and fifth rectangular sections. The first section is sized approximately two by three and one-half inches, the second and third sections are each sized approximately three by five inches, and the fourth and fifth sections are each sized approximately four by six inches. As such, the sheet can be easily divided into smaller sections according to the needs of the user.

Abstract: A rooftop drag reducing device includes a lower base portion fixedly mounted to the roof of a truck for semi-trailers. An upper portion of the drag reducing device is selectively movable relative to the base portion between a fully extended operating position, and a fully retracted storage position. In the fully retracted position, the upper portion is received within the lower portion such that at least part of the top surface of the lower portion is above the top surface of the upper portion. The design in accordance with the present invention increases the overall stability of the drag reducing device in both the extended and retracted positions, provides enhanced protection for the upper portion in its retracted position fully received within the lower portion, provides greater clearance than is possible with known drag reduction devices, and increases the maximum elevation within the cab or sleeper compartment of the vehicle to which the drag reduction device is mounted.
