  • Publication number: 20130292585
    Abstract: This invention provides for a removable/replaceable, wavelength-transforming sleeve/sheath to be placed around a primary UV radiation source that emits a primary UV wavelength spectral distribution; such that at least a portion of the sleeve/sheath transforms at least a portion of the primary UV wavelength spectral distribution to a different secondary wavelength spectral distribution. Additionally, the sleeve/sheath may help to prevent breakage of the primary UV radiation source and to contain the broken pieces in the event of breakage. In some embodiments, a portion of the sleeve/sheath may be coupled with a UV reflective surface to direct radiation in a preferred direction. Individual sleeves/sheaths may have various patterns of wavelength-transforming materials that emit one or more secondary wavelength spectral distributions and the sleeve/sheath may also have one or more sections that allow transmission of the primary UV wavelength spectral distribution.

  • Patent number: 8378324
    Abstract: An apparatus and a method, in a handheld portable multi purpose device, for producing multiple and variable wavelength distributions of UV radiation, or visible radiation, comprising a primary UV radiation source, and a system of wavelength transforming (WT) materials that allows selecting at will between UV A, UV B, UV C radiation (individual selections or various combinations,) and visible radiation, whereby the apparatus provides for UV sterilization of food, fluid, air, fluids, and surfaces; while also providing a means to emit visible light. Additionally, an apparatus and method, in a handheld portable multi purpose device, for enabling production and emission of UV radiation selectable between UV A, UV B, UV C radiation (individual selections or various combinations,) and visible radiation in a small form factor device embodied in a handheld portable flashlight, or lamp, type device.

  • Publication number: 20110154822
    Abstract: Heat engines suitable for large-scale or micro-scale fabrication supply power from a power turbine. The power turbine is driven in part by an ejector in which a working fluid is utilized as a motive flow. Fuel utilized for combustion may also be utilized as a phase-changing working fluid and as the motive flow driving the ejector. Heat exchangers particularly suitable for micro-scale implementation are also disclosed.

  • Patent number: 7781751
    Abstract: This invention provides a small form factor apparatus for selectively producing one or more of a plurality of wavelength distributions of radiation, comprising a UV Light Emitting Diode (LED) as the primary UV LED radiation source and one or more wavelength transforming (WT) materials separated from the primary UV LED radiation source, that in response to irradiation by the primary UV LED radiation source, produce transformed radiation having a wavelength distribution that is different from the wavelength distribution of the primary UV LED radiation source. None, one, or more than one of the various WT materials may be selected by the user, to allow either the primary UV radiation, or the transformed radiation, or both simultaneously, to be to be emitted from the apparatus in a preferred direction.

  • Patent number: 7148497
    Abstract: A variable wavelength ultraviolet lamp. An apparatus for selectively producing one or more of a plurality of wavelength distributions of light is provided, comprising a primary light source having a primary wavelength distribution, at least one wavelength-transforming material that, in response to illumination by the primary light source produces secondary light having a wavelength distribution different from the primary light wavelength distribution, the wavelength-transforming material being disposed on a substrate external to the primary light source, and a wavelength-transforming material selection mechanism for placing at least a portion of one or more selected wavelength-transforming materials in front of the primary light source, in a selected preferred direction of light emission from the apparatus, such that the selected wavelength-transforming materials emit from the apparatus light having a wavelength distribution different from the primary light wavelength distribution.

  • Patent number: 6243476
    Abstract: A system for generating loudspeaker-ready binaural signals comprises a tracking system for detecting the position and, preferably, the angle of rotation of a listener's head; and means, responsive to the head-tracking means, for generating the binaural signal. The system may also include a crosstalk canceller responsive to the tracking system, and which adds to the binaural signal a crosstalk cancellation signal based on the position (and/or the rotation angle) of the listener's head. The invention may also address the high-frequency components not generally affected by the crosstalk canceller by considering these frequencies in terms of power (rather than phase). By implementing the compensation in terms of power levels rather than phase adjustments, the invention avoids the shortcomings heretofore encountered in attempting to cancel high-frequency crosstalk.

  • Patent number: 5427278
    Abstract: An applicator for eradicating or removing transparent or translucent emphasizing inks, particularly from a paper surface, wherein the emphasizing ink has been used over permanent ink or a printed surface to emphasize such surface or a writing thereon. The applicator comprises a container, a liquid bleaching or oxidizing agent in the container for the emphasizing ink and means on one end of the container, such as a felt tip, roller, pressurized spray nozzle or hand pump, to apply a thin film of the ink removing agent to the emphasizing ink and to effect the eradication or removal thereof without substantially affecting the underlying ink or printed material which has been emphasized. In another embodiment of the invention, a dispenser of a neutralizing agent is also provided to abate the effects of excess bleaching or neutralizing agents on the surface being treated.
