Abstract: A device for duplicating magnetic disks and the like includes an inlet bin for holding magnetic disks, a motorized picker for selecting a disk from the bin along a substantially straight line pathm, a pressure roller for receiving the disk as it exits the bin and positioning the disk in a processing device, and a leaf spring for redirecting the path of the disk as it exits the processing device.

Abstract: The present invention relates to cursor control devices for computers, and particularly relates to cursor control devices for personal computers which involve the use of a ball rotatable by the fingers for controlling cursor movement.

Abstract: A flexible, multi-segmented support structure, and method for manufacturing same, particularly suited for use as a tent pole, wherein the support structure includes a plurality of tubular segments and each segment is connected to its adjacent segment or segments by lengths of elastic shock cord, the cord having sleeves affixed to each end thereof which can be affixed in partly or fully automated fashion to the respective segments. A novel ferrule is included to provide rigidity at the junctions of the segments, without providing undue stress concentration and to further assist in automating the manufacturing process.

Abstract: A light ball electronic mouse using a ball with a specific gravity between one and four, X and Y shaft encoders of substantially reduced diameter, and a pressure roller of substantially reduced force for controlling the position of a cursor in a video display.
