Abstract: A video distance learning system including a teaching classroom connected to remote learning classrooms by a fiber-optic communication network. The teaching classroom includes at least a rear audio/video cabinet housing four video monitors and a camera. The remote classrooms have front cabinets with four monitors and a camera. In a normal operating mode, one of the video monitors will display the teacher, while the other three monitors display classroom images. A rear video camera mounted is focused on the teacher and a front video camera may be focused on the students. The front video cabinet may have a graphics or document camera is also provided on the front video cabinet. The document camera points downward at a light table to image materials such as books, pictures and overhead transparencies. The teacher may switch between the rear camera, the front camera and the document camera. A teacher's work station, may be located at the front of the teaching classroom.

Abstract: An assembly of parts which form a stud for construction use. This stud assembly greatly reduces the material content of the stud assembly and reduces heat transfer and noise transmission over the known prior art and comprises two parallely arranged U-shaped channels interconnected by a novel mesh connector which interconnects the channels at one or more points along their length and is expandable only in a direction transverse to the longitudinal axes of the channels.
