  • Patent number: 9821168
    Abstract: Disclosed is a device having an oscillator and high voltage transformer connected to a glass-like tube filled with an inert gas or a mixture of inert gasses. The tube is located at the end of a wand having a handle. The output of the transformer is an RF high voltage signal. The output of the transformer is fed to the tube through a high voltage wire, where the signal excites the gas to produce a plasma-like beam. The tube is then applied to a patient's skin to aid in healing and the relief of additional ailments. The field generated by the tube interacts with the cells in the patient to increase transmembrane potential, stimulate ATP production, and inject negative ions and ozone into the surface of the user's skin to combat infection and disease.

  • Patent number: 6435704
    Abstract: A motor vehicle headlight has a light source, a reflector and a mask. The mask has one or more sets of masking elements, such as fins or annular rings, that face each other to form a passage. The passage extends through the mask in a direction away from the light source, thereby allowing heat to escape from the light source without optical leakage.

  • Patent number: 6281152
    Abstract: A conventional black oxide colorant used for the shielding coat membrane of the D2R type discharge lamps for automobiles has a problem that its wettablity with the granulated glass is not good so that a strong membrane is difficult to be obtained. A paint for the shielding coat membrane comprises polycrystalline silica and Mn-doped ferric oxide as a black colorant, which has a good wettability with the granulated glass and a shielding characteristics so as to improve the membrane strength, thereby providing a lamp with the shielding coat membrane that passes all evaluation test in the view point of the membrane strength, the light transmissivity, the discoloration, the suppression of pealing-off and cracking.

  • Patent number: 5984751
    Abstract: The invention relates to a method for producing an electric incandescent p which has at least one incandescent filament (31) and an anti-dazzle device (20). According to the invention, in the course of the method, an end (31a) of an incandescent filament (31) is threaded into a notch (23) on the edge of the anti-dazzle device (20) and fused with the anti-dazzle device (20) by melting the material of the anti-dazzle device (20) in the region of the notch (23) so that the melt wets the incandescent filament end (31a) arranged in the notch (23) and the incandescent filament end (31a) is embedded in the solidified material (20a) of the anti-dazzle device (20) after the melt has solidified.

  • Patent number: 5892325
    Abstract: A light source for backlighting a display panel comprises a light-emitting device such as an incandescent light bulb or LED array disposed within a cavity having diffusely reflecting walls and an aperture. A diffuser and brightness enhancing film are situated proximate the opening of the aperture which illuminates the display to be backlit. Preferably, light emerging from the aperture is substantially uniform in intensity and color, and in one embodiment, a color filter is employed to whiten the light emerging from the aperture. One embodiment has an aperture in which the ratio of the area of the aperture to the sum of such area and the surface area of the cavity is at least 0.05. In this embodiment, the ratio of the depth of the cavity to an edge to edge dimension of the cavity is at least 0.1.

  • Patent number: 5856723
    Abstract: The invention concerns an electrical incandescent lamp with a low-beam cap, articularly a two-filament halogen incandescent lamp and a production process for such a lamp, as well as a low-beam cap. Low-beam screening cap (12) has an opening (14), through which one end (6a) of low-beam filament (6) is threaded. This filament end (6a) is welded to the back side of low-beam screening cap (12) or to a current lead wire (8a), which is attached by a projection welding to the back side of low-beam screening cap (12). The fastening of low-beam filament (6) according to the invention makes possible materials savings in the case of a low-beam screening cap (12) and lower cost lamp manufacture.

  • Patent number: 5757127
    Abstract: A transparent thin-film EL display apparatus has a transparent thin-film EL element formed on a glass substrate. A rear substrate consisting of photochromic glass and the glass substrate on which the EL element is formed are disposed facing each other with the EL element located in between. A light-transmitting insulation material is inserted in a space between the two substrates and hermetically sealed. When the display on the EL element becomes hard to see due to light entering from the rear of the display apparatus, the photochromic glass reacts in response to the light and darkens the rear of the EL element, thereby blocking the light.

  • Patent number: 5646471
    Abstract: The capped high-pressure discharge lamp suitable for use in a vehicle headlight has a discharge vessel which is surrounded by an outer envelope. Current conductors extend from a respective electrode to a respective contact at a cap in which a first neck-shaped portion of the discharge vessel is secured. A return portion of one current conductor extends along an outside surface of the outer envelope. The outer envelope has a light-absorbing coating in a region near the first neck-shaped portion, at a side which is remote from the return portion. The outer envelope may have band-shaped coatings at either side, aside from the discharge path between the electrodes, at its side which faces the return portion. Stray light in the beam formed by the reflector and the lens of a head-light in which the lamp is used, is obviated. The bands provide for a rectilinear light/dark transition in said beam.
