Abstract: This invention teaches a methodology and an optical apparatus that provides long-term, archival storage using a chemically stable, high-resolution, photosensitive emulsion, such as silver halide, for the long-term, archival storage and retrieval of data, images and text. Multiple state data substantially increasing data density is stored as vertical diffraction gratings in the archival photosensitive emulsion. The data can be read out in parallel, substantially increasing retrieval speeds beyond that of current optical and magnetic techniques.

Abstract: A method and an amplifier for amplifying audio signals include a signal processor for processing incoming audio samples in preparation for amplification by an electronic amplifier circuit. A voltage is received from a power supply. Before the signal processor completes processing the incoming audio samples, an input level is estimated based on the incoming audio samples. In response to a comparison between the estimated input level and a threshold value, it is determined whether to boost the voltage received from the power supply. After the signal processor completes processing the incoming audio samples, an output level is estimated based on the processed audio samples. A determination is made, in response to the estimated output level, whether to adjust the threshold value used to determine whether to boost the voltage received from the power supply.

Abstract: A method and an amplifier for amplifying audio signals receive and process an incoming audio sample in preparation for amplification by an electronic amplifier circuit. A boost supply circuit receives a voltage from a power supply. A processor system determines whether amplification of the incoming audio sample warrants more voltage than the voltage received from the power supply. Before completing the processing of the incoming audio sample, the processor system sends a signal to the boost supply circuit to boost the voltage received from the power supply and to supply the boosted voltage to the electronic amplifier circuit if the incoming audio sample warrants more voltage than the voltage received from the power supply. Otherwise, the boost supply circuit passes the voltage received from the power supply to the electronic amplifier circuit.

Abstract: The invention combines several techniques applying high-resolution photosensitive emulsions for the long-term, archival storage of data, images and text. Data is stored as vertical interference patterns of multiple frequencies in a photographic emulsion. Read-out of the stored data uses a precision mechanism to locate and decode stored data.

Abstract: The present invention relates to sensor apparatus and methods, pertinent to electromagnetic energy in visible and other spectra, to capture and reproduce substantially all electromagnetic information within a relevant spectrum. This invention takes advantage of the wave properties of light, using tiny components dimensioned to the relevant wavelengths of light. Recent developments in nano-technology permit construction of wave-based detectors, instead of photon-counting receivers. These wave detectors can operate in the electromagnetic spectral range, including submillimeter, infrared, visible, ultraviolet and X-ray bands, with consequent low noise and tremendous sensitivity due to gain resulting from their inherent antenna construction. This invention provides for both non-contact and contact coupling methods between the sensor and the receiver/demodulator.

Abstract: This invention teaches how to fabricate a new type of full-spectra wavelength detector and spectrum analyzer in the form of antennas that make use of the wave properties of light. The detector's frequency detection range is controlled through the fabrication process. By miniaturizing the antenna detectors to the nanometer range and arranging them in an array a unique, full-spectrum imaging sensor is created.

Abstract: This invention comprises the means for the capture of full spectrum images in an electronic camera without the use of color primary filters to limit the spectral color gamut of the captured image. The fundamental principle of the invention is that each pixel of the image sensor acts as an independent spectrophotometer and spectral separator. Electromagnetic energy enters though a slit or collimating optic. Electromagnetic energy gets diffracted into component spectra by diffraction grating spectrophotometer for each pixel of image Electromagnetic energy leaves diffraction grating at different angles based on wavelength of the energy Spectrophotometer separates light for each pixel into its spectral components onto photodetector line array elements. Individual line array elements which are activated determine the original radiance level of the light source containing that specific wavelength region. The sum of these regions determines the spectral signature of the light at that pixel element.

Abstract: An apparatus providing full spectrum electronic images includes a full-spectrum light source, a programmable diffraction grating to separate light from the source into its spectral components, a reflection system controllable on a pixel by pixel basis to modulate light output from the diffraction grating, and a scanning mirror to form an image from light modulated by the reflection system. A related method for displaying a full spectrum image includes providing full spectrum light, using a diffraction grating to separate the light into its spectral components, and for each pixel of the image, modulating the intensity of the spectral components to produce a light output characteristic of such pixel, and additionally using a scanning mirror arrangement to form the image.
