A keyboard with a thumb-controlled curser. In a preferred embodiment a circular aperture about one centimeter in diameter is provided in the spacebar of the keyboard. A keyboard user controls the position of the computer curser by moving a portion of his thumb across the port. A light source illuminates an exposed surface of the user's thumb as it moves across the port. Light patterns reflected from the user's thumb are focused on a sensor. The output from the sensor is transmitted to the computer processor where the thumb movements monitored by the sensor are turned into control signals for controlling the position of the curser on a computer monitor.

A container body has a main opening large enough to permit passage of large paintbrushes or sprayer suction lines and filters. This opening is covered with a large cap that comprises a bayonet-type seal. Special features in the cap and in the body combine to provide a swivel pour valve permitting contents of the container to be poured from the can in a controlled manner with no spillage or mess. The cap has a close position, a remove-replace position and a pour position. A sealed-closed position is achieved with cap rotation in a first rotation direction from a first cap remove-replace position and the pour position is achieved by cap rotation in the same rotation direction from a second cap remove-replace position. Preferably a pour vent is provided. It could be covered with a threaded screw or snap-on cover.

Clean container for paint and other fluids

A can for holding paint and similar products. The can has a rectangular bottom, preferably square, and rectangular sides providing a space savings of about 20 percent as compared to round cans. It has a main opening large enough to permit passage of large paint brushes or sprayer suction lines and filters. This opening is covered with a large cap. A swivel pour valve permits paint to be poured from the can in a controlled manner with no spillage or mess. In a preferred embodiment, the swivel pour valve is an integral part of the large cap covering the large opening. The can is preferably made of plastic which eliminates problems of rust and other corrosion problems.
