Abstract: A screen segment, viewing isolation apparatus is provided for a video screen that is divided up into plural screen segments and includes a housing which includes a plurality of optical channels, wherein each of the optical channels is registrable with a respective screen segment. When a video screen is divided into four screen segments, four players can employ an embodiment of the invention to see their respective screen segments without being confused by screen segments of other players. An embodiment of the invention that accommodates four players can be converted into an embodiment which accommodates two players for separately viewing two screen segments. The housing includes a top housing wall, a bottom housing wall, and exterior wall supports connected between the top housing wall and the bottom housing wall. An interior vertical partition is connected between the top housing wall and the bottom housing wall at medial positions of the top housing wall and the bottom housing wall.

Abstract: A nasal stethoscope including a nostril tube for insertion into a human nostril, a spring-type clip affixed to the nostril tube, and a pad affixed to a first jaw member of the spring-type clip. The spring-type clip is movable between a closed position and an open position. The pad is interposed between the nostril tube and the first jaw member. A connector tube is affixed to an end of the nostril tube opposite an open end of the nostril tube. An earpiece tube can be removably connected to an end of the connector tube opposite the nostril tube. The clip has a second jaw member directly affixed to an outer surface of the nostril tube. The clip extends in generally parallel relationship to a longitudinal axis of the nostril tube. The first jaw member has an arm extending outwardly therefrom so as to move the clip from the closed position to the open position. The first and second jaw members have tapered ends narrowing toward an end of the nostril tube.
