Abstract: A motorized roller television cover conceals a television set when the television is not in use. The motorized roller television cover utilizes a first mounting bracket, a second mounting bracket, a roller, an aesthetic sheet, and a motor to create a more aesthetically appealing atmosphere than leaving the television set exposed. The first mounting bracket and the second mounting bracket support the roller, the motor, and the aesthetic sheet on a television set. The motor actuates the rotation of the roller to extend or retract the aesthetic sheet to display the aesthetic sheet or expose the television set. The roller is able to be quickly installed onto or removed from the first mounting bracket and the second mounting bracket to replace or interchange the aesthetic sheet in accordance to the user's preference.

Abstract: A random refresh vector-generator type display system using a hybrid digital/analog vector generating technique. A digital vector generator decomposes medium length vectors into sub-vectors which are then drawn by an analog vector generator including a delay line. The system utilizes a long vector drawing technique wherein the first portion of a long vector is drawn at a first speed, the middle portion is drawn at a greater speed, and the final portion is drawn at the first speed. A feed forward circuit compensates for the sluggish response of deflection amplifiers of a display monitor so as to more precisely define beginning and end points of vectors. These amplifiers are further compensated by a delta theta circuit which temporarily freezes the system clock to allow the amplifier time to settle so that successive vectors will form sharp corners.
