Abstract: A computer-implemented method for generating labelled training images characterizing manipulation of a plurality of stackable objects in a workspace. The method includes: obtaining a first training image subset obtained at a first time index comprising a depth map and a visual image of a plurality of stackable objects in a stacking region of a workspace; obtaining a second training image subset obtained at a second time index comprising a depth map and a visual image of the stacking region in the workspace, wherein the second training image subset characterizes a changed spatial state of the stacking region; computing a depth difference mask based on the depth maps; computing a visual difference mask based on the visual images of the first and second training image subsets; generating an annotated segmentation mask using the depth difference mask and/or the visual difference mask.

Abstract: A printing device that may include a first print engine, a second print engine, and a web buffer device disposed between the first and second print engines to maintain an amount of web substrate therein, wherein the web buffer includes a first and second movable carriage, with at least one rotatable roller coupled to each of the two carriages and wherein the first and second movable carriages move synchronously away and toward each other to alter an amount of web present in the web buffer.

Abstract: An expansion card with an integrated fingerprint acquisition system is provided that is able to be connected to a portable computer. In one aspect of the invention, PCMCIA standards are used for the expansion card. The expansion card is built such the fingerprint acquisition system is on a slidable carriage which may extend out from the expansion card housing, or may be retracted into the housing when the fingerprint acquisition system is not in use. A locking mechanism keeps the carriage in the retracted position, and a spring provides the force necessary to slide the carriage into the extended position when pressure is placed on the slidable carriage. An advantage of the invention is that the fingerprint recognition device is small enough to fit within a PCMCIA standard expansion card.
