Title: Printing and quilting method and apparatus
Inventor: WHITE BURL
IPC: B41J2/01
Filed: 2001-01-09
Abstract: A quilting machine (10, 100, 200, 300, 400, 500) is provided with a printing station (20, 125, 225, 325, 425, 525) and a quilting station (44, 127, 227, 327, 427, 527). The printing station is located either in line and preferably upstream of the quilting station, with a conveyor (520) extending through each of the stations to convey a web of quilting material through the machine, or is off of the quilting line such that the material with a pre-applied pattern thereon is transferred, preferably in web form, to the line of the second station for the application of a pattern in registration with the first applied pattern. At the quilting station, registration longitudinal and transverse registration is measured and skewing or rotation of the material is determined. Opposite transverse sides of the material are differently adjusted to orient and register the material.  A master batch controller (90, 135, 235, 335, 435, 535) assures that the proper combinations of printed and quilted patterns are combined to allow small quantities of different quilted prod-ucts to be produced automatically along a material web. Ticking is preprinted with a plurality of different patterns, organized and communicated by the computer so that a print head can scan the material and print different patterns of different panels (32) across the width of a web. Identifying data (40) for matching the panels of a mattress product can be provided in data files printed on the fabric. Cutting and slitting of the panels from each other and the quilting and combining of the panels for assembly of a mattress product can be carried out manually or automatically using the data.

Abstract: In a vehicle traffic system, the predetermined nominal trajectory (20, 22, 24, 26, 28, 30) for an autonomous vehicle (32) is varied periodically within acceptable boundaries which define a permitted travel corridor (46). The corridor's boundaries ensure the continued safe and controlled operation of the vehicle (32) within the system. In an embodiment of the invention, alternative trajectories (54) are selected randomly; in another, they are parallel to one another (50, 52). In yet another, preferred embodiment, judiciously-selected, alternative trajectories are repeated periodically according to a predetermined schedule designed to avoid repetitive travel over the same precise path, and possibly also selected for optimal results under different terrain, environmental, and/or operational conditions. Thus, by avoiding repeated passage precisely over the path of the nominal trajectory, rutting on the road is greatly reduced and a more uniform surface is maintained for travel.
