Abstract: A computer architectural and apparatus system for preventing software copying or alteration, and providing enhanced computational capabilities, physical information security, and physical environment protection is disclosed. The system comprises an Independent Computer Module (ICM), and an Interface Unit. The ICM comprises a CPU, a RAM, a ROM, a memory switching means, a communications port, and a connectorless interface contained within a sealed cartridge. The Interface Unit comprises a receptacle for receiving the ICM, which contains a matching connectorless interface, and wiring to a host computer's port and power. The connectorless interface uses directional electro-magnetic emitters and sensors to prevent signal leakage. The memory switching means turns off the entire secure memory, enabling non-secure programs to be run from another section of RAM. Reactivation of secure memory by a non-secure program causes program control to be transferred to a fixed address within the secure program.
Abstract: A means and method of controlling a plurality of energy beams with at least one of the plurality of beams. At least one first beam set produces special interference with at least one second beam set, at a first location(s), diverting energy from both beam sets to a second location(s), where energy does not appear from one . . . or either, of the inputs in the absence of interference. By selecting the timing, levels, phases, frequencies, and interconnection of multiple controllers, a multitude of useful energy beam circuits are able to be made . . . such as: gated amplifiers, cascaded amplifiers, gated oscillators, phase demodulators, active filters, inverters, inverted filters, limiters, threshold detectors . . .
Abstract: A means and method for performing frequency-multiplexed logic, amplification, and energy beam control functions on individual channels simultaneously within a single device by using a plurality of frequency-multiplexed inputs each having beam sets of matching channel frequencies and simultaneously producing a set of interference images, one for each channel, and separating energy from the images to produce a frequency-multiplexed output. The individual functions performed on individual channels are the result of constructive and destructive interference within each channel's image.
Abstract: A portable secure computer architecture, apparatus, and method for protecting information and at least one program for controlling that information is disclosed comprising: a computer protected inside of a single sealed cartridge, the computer having a CPU, Memory, and a communications means for communicating with a host computer outside of the cartridge. All internal information and external communications are exclusively controlled by the internal program. Provision is also made for running a second program inside the architecture, while protecting secure information from that second program. Secure information is placed in a bank switched subdivision of memory. The subdivision is switched off by the information controlling program before the second program is permitted to run. Reactivating the protected subdivision causes a simultaneous non-maskable interrupt halting the second program and transferring control back to the first program.
Abstract: A means, method and apparatus for dual-phase amplification of wave-type signals is disclosed comprising superimposing a constant level beam set and a modulated beam set to produce a first interference image at first and second locations. A first image component separator separates energy from constructive and destructive interference component regions to produce secondary beam sets that are combined to produce a second interference image, which is separated at a destructive interference region to produce the output. The amplifier with multiple inputs is then connected in cascade, as a phase-bistable device, as a level detector, an AND, an OR, and/or a synchronized oscillator. Multiple frequencies work independently, allowing for frequency-multiplexed functions.
Abstract: A means, method and apparatus is disclosed for providing at least one phase-modulated output from at least one amplitude-modulated input, which is used to produced the logical AND and OR functions having phase modulated outputs. A constant level bias beam set of at least one wavelength of any wave-type energy is superimposed on at least one modulated input beam set having an energy sum out of phase with the bias beam set at at least one location. Energy in the resulting interference image is separated from said at least one location to produce at least one output. Input levels determine the function performed. When the input energy sum is greater than the bias beam set, the output changes phase. When they are equal, the output is zero, which is also used to produce the NAND function.
Abstract: A fundamental method and apparatus for using wave-type energy, such as light, to provide: amplification, energy control, and logic functions including OR, EXCLUSIVE OR, and INVERTER; as well as: bistable information storage; computing; visual display; and dynamic imaging (where images are modified continually as computation proceeds) is disclosed. The method uses modulated input beams that are able to produce interference fringes, that are separated into constructive interference component regions and destructive interference component regions, to provide outputs from individual functions, that result from the interference which occurs in the separated interference-fringe component regions. Many basic functions are interconnected to produce more complex functions including complete digital and analog computers. Holograms made up of many subholograms are used to separate fringe component regions, and to direct function interconnecting beams.
