Abstract: An improved vacuum cleaner bag with a mechanism for allowing the user to visually align the coupling opening of the vacuum cleaner bag with the discharge tube of a vacuum cleaner. The vacuum cleaner bag also includes a discharge tube receiving structure positioned opposite the coupling opening for receiving the tube end of the discharge tube when the collar surrounding the coupling opening is being positively seated around a base end of the discharge tube.

Abstract: A CD-ROM, that is adapted for the protection of electronically transmitted data, comprising a CD-ROM, having a hub containing a battery power supply and a microprocessor, which receives signals from several laser light sensors, located on the read area of the CD-ROM. The computer communicates directly with this CD-ROM by positioning the laser so that it strikes specific laser light sensors, with the order of sensors struck used by the computer to communicate directly with the CD-ROM. The CD-ROM communicates information to the computer, via the user who reads information on a liquid crystal display readout, located on the CD-ROM, and types in the information on the computer keyboard. This CD-ROM is used as a personalized key, for both installing and updating programs for continued use.

Abstract: A floppy disk, having a microprocessor and battery power supply, a magnetic field sensor, and an on switch on the central hub. A plurality of magnetic fields are placed on the disk housing, in a circular pattern around the disk's axis of rotation, and are detected using a magnetic field sensor located on the hub. When the floppy disk is placed into the computer's drive bay, the computer disk drive motor does an initial series of operating and idle time increments. The floppy disk magnetic field sensor detects the number of revolutions of the disk, and stores the revolutions per time increment. The computer then communicates with the floppy disk, using disk motor operation and idle times. The floppy disk communicates information to the computer, via the user who reads information on a LCD readout, located on the floppy disk, and types in the information on the computer keyboard. The floppy disk is used as a personalized key, for both installing and updating programs for continued use.

Abstract: For commercial and residential use, a wall-mounted enclosed towel warmer has a bottom-hinged tilt-out front cover which includes an integral top panel. In the tilted-out cover position an internal towel holder also tilts outward to provide convenient top access for loading or removal of a towel. When the cover is pushed closed, a latch retains it in the closed position where the exterior presents a smooth flat profile having only a shallow protrusion of a few inches from an unaltered wall surface, providing a high degree of user safety, especially regarding children. In this closed position, the towel becomes intimately sandwiched between several thin profile electric heating elements located on both sides of the towel holder and on inner surfaces of the enclosure, arranged to warm the towel uniformly to avoid hot and cold regions which tend to occur with conventional open type towel-warming devices. A front control panel provides touch pads and illuminated message displays.
