Abstract: A digital signal processing system which samples an analog voltage, converts the sample to a multi digit base four number, performs a computation with this number, using base four arithmetic, and converts the result back to an analog voltage. This system is comprised of a system an analog to digital converter, an arithmetic logic unit, a digital to analog converter, a system controller, and a memory. The analog to digital converter samples the analog signal and converts the samples into base four numbers. The arithmetic logic performs computations on the samples. The digital to analog converter converts the results of the computations back into analog signals. The system controller controls the operation of the arithmetic logic unit, and the memory stores the command instructions for the system controller. The main advantage of using base four arithmetic instead of binary is much faster through put.

Abstract: A space vehicle launch system is proposed which utilizes a vacuum filled lighter than air vessel to lift a rocket powered vehicle to a high altitude where the vehicle can easily blast into outer space. The main advantages of this system are that, first, the rocket would not need to carry a large mass of fuel, and, therefore, this system would be much safer than the state of the art. Second, the vehicle would be lifted slowly through the atmosphere, and would not suffer any damage due to abrupt acceleration or air friction.

Abstract: This invention consists of a data communications interface that provides the means for an electronic, binary, data processing apparatus, or digital computer, to encode information in a base four format, and to communicate, with other data processing apparatuses, which utilize this invention, by exchanging base four digits, in a serial manner, via a standard data communications medium, such as a telephone line. This invention is composed of a serial communication device (SCD) and a line driver (LD). The SCD converts parallel, binary data to serial, base four data, and visa versa. The LD converts base four voltage levels to signals that are appropriate for the communications medium, and visa versa. A tone, for example, would be an appropriate signal for a telephone line. This invention enables information to be exchanged much more rapidly than is possible with a state of the art system.
