Abstract: A wheelchair lamp that is primarily for making a wheelchair more visible. The wheelchair lamp includes a housing that is mounted to the wheelchair. An extendable member having a light on top extends from the housing. The extendable member may be extended and retracted. A motor is contained within the housing to extend and retract the extendable member. An electrical conductor is longitudinally disposed with the extendable member. The electrical conductor electrically connects the light and the power source. A switch is used to selectively connect the motor to the power source causing the motor to operate so that the motor may extend or retract the extendable member. The light is extended and lit when a wheelchair user is near traffic or potentially at risk for a collision and is typically retracted when the user is indoors.

Abstract: An apparatus for use in projecting a picture image onto a remote surface includes a frame assembly, a stage assembly, and a support assembly. The frame assembly receives a light source and a light pipe through which light from the light source is transmitted and cooled, the stage assembly supports a plurality of discrete transparencies, and the support assembly supports a projecting lens and a reflecting mirror. The stage assembly includes a stage glass for supporting discrete transparencies. The stage glass is rectilinearly displaceable so as to permit any discrete point of the stage glass to be positioned above a light source.

Abstract: A form of eye protection intended for use in protecting the eyes of a dental patient against foreign particles and contaminants basically includes a frame, a shield supported by the frame, and a strap for securing the frame in a desired position on a wearer's head. The eye protection device is structured and configured to conform to the contours of the wearer's nose and cheeks so as to form a contact seal between the eye protection device and the wearer's face. The eye protection device is further structured and configured to be angularly positionable relative to the wearer's face so as to remain spaced from the wearer's forehead and thus, preclude foreign particles and contaminants from entering the wearer's eyes.
