Abstract:
A method for making a cooling body for a lighting device may include: a) Providing multiple aluminum nitride ceramic radiators; b) Putting the multiple aluminum nitride ceramic radiators into a mold; c) Closing the mold, and injecting a melting metal into the mold so that the metal encloses a portion of each of the aluminum nitride ceramic radiators, wherein the metal has a melting point lower than that of the aluminum nitride ceramic radiators; and d) Opening the mold, and obtaining the cooling body.
Abstract:
An apparatus comprising an input circuit, a storage circuit and an output circuit. The input circuit may be configured to generate a plurality of data paths in response to an input data signal having a plurality of data items sequentially presented in a first order. The storage circuit may be configured to store each of the data paths in a respective shift register chain. The output circuit may be configured to generate an output data signal in response to each of the shift register chains. The output data signal presents the data items in a second order different from said first order.
Abstract:
Strips of field emitters arranged in rows overlap grid electrodes when viewed in the viewing direction to define pixel dots. Scanning electrical voltages are applied to the rows of field emitters to perform scanning and data potentials are applied to the grid electrodes to control the brightness of the display. Potentials applied to the grid electrodes also focus the electrons from the field emitters. A metal mesh with grid electrodes fabricated thereon to form an integrated structure greatly simplifies the manufacture of the display.
Abstract:
Sputtering of the cathodes of a cold cathode fluorescent lamp is reduced or eliminated by removing electrodes altogether from the sealed envelope containing the gaseous medium. Electric field is then applied by means of electrically conductive members outside the tube. Alternatively, the current passing between electrodes can be spread over multiple sub-electrodes so that the current flow and sputtering experienced by each individual sub-electrode will be reduced. Different designs are employed to facilitate heat dissipation for high power and high intensity cold cathode fluorescent lamp applications. Thus, a container for the fluorescent lamp tube may be omitted altogether and adjacent rounds of a spiral-shaped lamp may be attached together by an adhesive material. Alternatively, the container may be open at one end to facilitate heat dissipation. Or the container for the lamp and the housing from the driver may each contain a hole to allow air circulation to carry away heat.
Abstract:
The present invention relates to a flat parallel light source using the principle of the mirror reflection and diffuse reflection, which comprises a light source, a diffuse reflective chamber with high reflectance walls, a light coupler, a small hole array at the top surface of said diffuse reflective chamber, a mirror reflective cone array on the small hole array, and a convex lens array on said cone array. The light generated by the light pass through the light coupler into the diffuse reflective chamber, and then pass through the small hole array, mirror reflective cone array, and lens array to form parallel light. The flat parallel light source can generate a high intensity parallel light with excellent parallelism or a given scattering angle parallel light. It can be used for backlighting for all kinds of LCDs, and other equipment where parallel light is needed. It can also be used in LCDs to increase the brightness of the display image and reduce power consumption.
Abstract:
An apparatus and method for determining a parameter of a particle in a fluid is disclosed and, in particular, an apparatus and method for determining contamination or machine wear by the measurement of contamination or wear particles in a fluid used in the machine is disclosed. In a first embodiment, a measurement cell is provided with a fluid flow path. A first hall probe is arranged adjacent to the flow path for detecting dia-magnetic, para-magnetic, ferro-magnetic particles and a second optical sensor formed of a light emitting diode and phototransistor are provided for optically detecting the particles. A correlation between the hall probes and the optical detector enables an indication of the particles to be obtained so that a parameter of those particles can be determined to provide an indication of contamination or machine wear. In a second embodiment, a measurement cell having a fluid chamber is provided and two pulsed light sources are arranged in the cell for transmitting light through the fluid to a charged couple device so that a first image can be produced by light transmitted through the fluid and therefore past the particles and a second pulsed light source is provided for reflection of particles so that a second image of reflected light can be produced. A comparison of the first and second images enables the metal particles to be determined so that parameters of those particles can be measured to provide an indication of contamination or machine wear.
Abstract:
A prone cushion having at least one layer of material, a neck portion, and a torso portion being designed to support a user who is reclining in a prone position. The prone cushion may be adapted to have an upper layer and a bottom layer. The prone cushion my have a leg cavity for storing a height adjustment leg. The height adjustment leg may be stowed in the leg cavity when not in use, or may be placed under the prone cushion to adjust the height while in use. The density of the cushion may vary along the length of the cushion by inserting a plurality of holes into the at least one layer of material.

Abstract:
The present invention is directed to a method of treating, preventing, or reducing the risk of bone deterioration or osteoporosis in a peri- or post-menopausal female subject. The method involves selecting a peri- or post-menopausal female subject in need of treating, preventing, or reducing the risk of bone deterioration or osteoporosis and administering hepcidin to the selected subject under conditions effective to treat, prevent, or reduce the risk of bone deterioration or osteoporosis.
Abstract:
This invention discloses a novel class of skincare products to remove iron in the skin and its preparation method. The core active components, termed as de-ironizing inducers (DII), consist of a reducing agent and a precipitating agent. The reducing agent is selected from vitamin C, vitamin E, glutathione, vitamin A, vitamin D and their derivatives. The precipitating agent is chosen from calcium carbonate, pearl powder, magnesium carbonate, barium carbonate, calcium phosphate, magnesium phosphate, barium phosphate, calcium silicate, magnesium silicate, and barium silicate. Molar ratios of the reducing agent with the precipitating agent range from 1:3-6 and the core components in the skin care product range from 5% to 10% w/w. The PH value of the skincare product is between 6.6 and 7.4. The skin care products can safely and effectively remove iron in the skin, which has been shown to accelerate skin's natural aging and photoaging.
