  • Patent number: 8132198
    Abstract: An apparatus includes an optical data storage medium comprising a longitudinal portion at a resting location and a counterweight attached to the optical data storage medium. Unless the longitudinal portion is locked in place, the counterweight causes the longitudinal portion to move from the resting location when the optical data storage medium is rotated thereby rendering at least some data on the optical data storage medium unusable.

  • Publication number: 20120048327
    Abstract: Described herein are processes and apparatuses for preparation and optimization of photovoltaic films and film stacks with application of electrical pulses. The process achieves high photovoltaic efficiency upon application of conditioning electrical pulses to the stack or layers of deposited photovoltaic films. This may be done at manufacture, or in the field at certain time intervals. The films of photovoltaic devices may be optimized by application of programmed voltage pulses. Furthermore, it is possible to deliver larger portion of energy from the pulse to a particular layer of a multi-stack film by rendering one or more layers of the film relatively more conductive using exposure to selected narrow wavelength of light corresponding to the band gap of the particular layer.

  • Patent number: 7955682
    Abstract: A system for recording and/or transmitting optical data or visual images includes an optical data or visual image recording medium and a light and/or heat source. The medium includes a markable coating established on a substrate. The markable coating includes a leuco dye and a developer precursor including a compound that undergoes rearrangement in response to a stimulus, thereby forming a developer that reacts with the leuco dye. The light/heat source is positioned so as to illuminate and/or heat the medium in a predetermined manner to i) cause photochemical and/or photothermal rearrangement of the developer precursor to form the developer which reacts with the leuco dye to form an optically detectable mark, or ii) cause at least one optically detectable mark previously formed on the markable coating to produce at least one readable pattern.

  • Publication number: 20110111336
    Abstract: An absorber with significant absorbance matching the processing radiation is included in the compositions for efficient capture of energy. Embodiments of the present disclosure can also be viewed as providing compositions that have a functional film precursor such as an ink that might include, a colorant, toner, polymer, dye, pigment, or a reactive component such as polymer precursors, and an absorber that is capable of absorbing radiation wavelength that is “matched” to the waveband of the processing radiation.

  • Publication number: 20110108773
    Abstract: Methods and systems disclosed herein involve conversion of precursors to electronic films with many properties such as conductor, resistor, semiconductor, photovoltaic, insulator and optical conversion films. There are a large number of materials such as transition metal oxides, metals, combination oxides that may be deposited as organic precursors and subsequently processed by radiated energy. In practice of the systems and methods disclosed herein, the films are processed by a “matched” radiation to either intrinsic absorption of the film precursors, or due to an added absorber to the film precursors. Since many of the precursors have been previously described as “Metal-Organic” precursors, the process can be described as “Metal-Organic Deposition by Enhanced Light-Absorption” (MODEL-A).

  • Publication number: 20110111134
    Abstract: Described herein are systems and methods for deposition of films using energy dispensers combined with film-material dispensers. The processes achieve high energy efficiency and speed by deposition of film materials that absorb energy in a designed radiation band, coupled with delivery of energy using a radiation source with a band matched to the absorbance band of the film deposition material. It is possible to use the energy for drying, fusion, chemical conversion, sintering of the deposited materials to produce films for visual, graphic or electronic applications. The process does not cause significant heating of substrates. The energy can be delivered to specified material deposition locations, thus using substantially less energy than bulk heating.
