Abstract:

The retractable mouse pad for computers provides a mouse pad that is built into the housing of a portable computer or other portable electronic device, such as a laptop computer, a notebook computer or the like, or, alternatively, into the housing of a computer keyboard or the like. The housing has a slot formed therein, preferably along a lateral edge thereof. The slot is in open communication with a recess defined within the housing. A substantially planar plate having opposed upper and lower surfaces is slidably and releasably disposed within the recess. The upper surface of the plate is adapted for supporting a computer mouse, and the lower surface is adapted for mounting on a support surface, such as a desktop or the like. The plate is automatically driven to at least partially slide through the slot to an exterior of the housing.

Abstract:

The system for unclogging toilets is a pressurized air-based unclogging system for toilets, allowing clogs formed on either side of a bend in a toilet outflow pipe to be cleared simultaneously. The system includes a tube mounted on a toilet so that a pair of peripheral apertures and a central aperture formed through a lower end thereof communicate with an interior of the bend of the pipe. A plunger is slidably mounted within an interior of the tube, and has an expandable bladder mounted thereto. An air pump delivers pressurized air to the interior of the tube through a port formed through an upper end thereof so that the plunger is driven downward while simultaneously filling the expandable bladder, which projects through the central aperture. The expandable bladder creates a barrier within the bend and pressurized air flowing through the peripheral apertures is delivered to either side of the bend.
