    Abstract: Disclosed is a switch that allows a peripheral device, such as a PCL printer, to be shared by multiple computer systems. The switch connects to each of the computer systems, and also to the peripheral device being shared. The first system is considered the primary user of the peripheral device, so when the second system requests access to the peripheral device, the switch causes the peripheral device to save its state temporarily while the second system uses the device. When the second system's use is complete, the switch causes the peripheral device to restore its state to the last state established by the first system. Therefore, the first system need not know that the other system used the peripheral device, since the state of the peripheral device appears unchanged from the last time the first system used the device.

    Abstract: Illustrative embodiments of systems and methods for improving traction of a bicycle are disclosed. The invention described are traction loops comprised of a strap having projections extending therefrom. The loops are fastened around the width of the tire using a fastening device. The loops may be easily applied and removed to provide the rider with flexibility to use the loops on slicker surfaces and remove them when riding on drier surfaces. The loops may further be easily stored on the bike when not in use.

    Abstract: An apparatus providing the capability to scan transmissive media is presented. The apparatus comprises an illuminating lid for an optical scanner. The lid is hingeably attached to the base of the scanner and provides a backlight for transmissive media. A light source, located within the lid, projects light through a translucent screen, through an X-ray for example, onto photodetector arrays located within the base of the scanner. Control means are provided to maintain the light intensity of the light source located within the lid so that a flat light profile is provided during the scan.
