Abstract: A seamless laboratory countertop (10) including an inner core (38) of relatively lightweight rigid material having top and bottom surfaces and at least one side surface extending between the top (42) and the bottom (44) surfaces. A reinforcement layer (40) of fiber-reinforced thermoset resin is secured to and covers the top and the bottom surfaces of the inner core (38), and a layer of thermoset resin is secured to and covers the side surface of the inner core. The thermoset resin on the side surface is the same as the thermoset resin of the reinforcement layer. The countertop also includes an outer layer (12) of non-reinforced thermoset resin secured to and covering the reinforcement layer over the top surface of the inner core to provide a smooth work surface.

Abstract: The present invention is directed to an electronic display stand that can advance through musical notes without interrupting a musician's performance. The stand can be controlled by remote mechanical actuation, the sound of musical notes, or a timed interval. The device can have a display large enough to display a full page of sheet music at one time. A plurality of the devices can be networked to simultaneously display musical notes to a number of musicians. The electronic display stand is a multi-function device that can be used for displaying more than just music.
