A pointing device for controlling cursor operation on a computer monitor screen. An operator controls the motion of a movable reflective surface. A stationary light source directs light onto the movable reflective surface and the light is reflected to a stationary light sensor. A signal processor receives signals generated by the stationary light sensor based on light reflected from the movable reflective surface. The processed signals are transferred to a computer processing unit and are utilized to move a cursor across a monitor screen in a manner that corresponds to the motion of the movable reflective surface. In a preferred embodiment the light source is a laser light source. Also, in a preferred embodiment, two joysticks are provided in front of the keyboard space bar. The joysticks are used to control the motion of the movable reflective surface and right/left clicking with the thumbs of the keyboard operator while his fingers are kept in an appropriate position for typing on a computer keyboard.

A hydraulically lifted toilet seat. A hydraulic linear actuator mounted within a lift unit rigidly attached to the toilet bowl unit utilizes utility water pressure to provide a force to lift the toilet seat. In a preferred embodiment a drive arm of the hydraulic linear actuator applies a tension force to a flexible tension element which is in turn attached to a sheave that is rigidly attached to an axle rigidly attached to the toilet seat. Actuation of the drive arm of the linear actuator causes the sheave, axel and the toilet seat to pivot about 100 to 110 degrees from a horizontal position to a raised position leaning against the toilet tank. In the preferred embodiment the flexible tension element is a nylon cord attached to the sheave through a pulley. In this preferred embodiment the hydraulic linear actuator is controlled by a spring loaded three-way valve or two two-way spring loaded valves permitting users to raise or lower the seat by temporally positioning valve handles up or down. In this embodiment the pressure line to the actuator is connected to a vent line to a float cutoff valve in the toilet tank so that when the toilet is flushed, pressure in the hydraulic linear actuator is relieved causing the toilet seat to lower to its horizontal position each time the toilet is flushed. Embodiments are provided that come in kit form to permit easy installation without plumbing expertise on almost any toilet in the United States.

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.
