摘要:
Embodiments of the present invention allow participants in a networked virtual world to converse naturally as in a real-life situation. Each participant can hear “nearby” participants localized according to their positions in the virtual world, desirably with reverberation and environmental audio effects derived from properties of the virtual world.

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.
摘要:
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.
摘要:
An apparatus for selectively producing one or more of a plurality of wavelength distributions of radiation. The apparatus comprises a primary UV radiation source and one or more wavelength transforming materials separated from the primary UV radiation source, that in response to irradiation by the primary UV radiation source, produce transformed radiation having a wavelength distribution that is different from the wavelength distribution of the primary UV radiation source. None, one, or more than one of the various WT materials can be selected by the apparatus, to allow the primary UV radiation, any individual transformed radiation, or any combination of the various radiations to be to be emitted from the apparatus.

A harness to be worn during situp exercises, the benefit being that it provides a non-moving portion to support the head. The cross strap behind the head which constitutes this non-moving portion is mounted on straps held about eye level by the hands during situps, wound partially around the upper torso, and attached in front of the body to a belt.

摘要:
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.
摘要:
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 an area and which applicator comprises a container, a liquid bleaching agent in the container for the emphasizing ink and means on one end of the container, such as a felt tip or roller, to apply a thin film of the liquid bleaching agent to the emphasizing ink and to effect the eradication or removal thereof without substantially affecting the removal or eradication of the underlying ink or printed material which has been emphasized. A method of eradicating transparent ink markings from a surface, such as a paper surface, which method comprises applying a liquid bleaching agent over the ink marked portion of the surface to be eradicated to chemically bleach and eradicate the ink material so marked without substantially affecting any printed ink or print on the underlying surface.
摘要:
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.
