  • Publication number: 20140043458
    Abstract: A human body data matching method for medical cosmetic applications includes the step of providing a human body imaging system having a digital image pickup module for scanning and photographing human bodies to obtain image data, the step of rendering the image data into human digital images, the step of storing the human digital images in a databank, the step of fetching pre-stored storage human digital images of the person going to take an orthopedic or cosmetic surgery from the databank, and the step of matching the fetched human digital images and then performing the orthopedic or cosmetic surgery. This method prevents surgical errors due to misunderstanding in communication between the surgeon and the patient.

  • Patent number: 7563457
    Abstract: A design strategy for constructing hierarchically structured materials using nanoparticles and synthetic biopolymers has been developed. Block copolypeptides or homopolymer polyelectrolytes are used as structure-directing agents to arrange nanoparticles (composed of metals, metal non-oxides, metal oxides, or organics) into unusual microstructures, such as spheres, “apples” and “cups.” Hollow spheres can be made wherein nanoparticles of one composition are spatially oriented completely interior or exterior to nanoparticles of a second composition. These aggregates contain nanoparticles only in the shell walls, and maintain their hollowness upon calcination. These shapes can also be fabricated into films. These robust materials are anticipated to have great promise in applications that require surface catalysis, magnetic/electronic/optic properties, transport capabilities, and combinations thereof, such as drug delivery, packaging, catalysis, and sensors.

  • Publication number: 20080113169
    Abstract: A material and an associated method of formation. A self-assembling block copolymer that includes a first block species and a second block species respectively characterized by a volume fraction of F1 and F2 with respect to the self-assembling block copolymer is provided. At least one crosslinkable polymer that is miscible with the second block species is provided. The self-assembling block copolymer and the at least one crosslinkable polymer are combined to form a mixture. The mixture having a volume fraction, F3, of the crosslinkable polymer, a volume fraction, F1A, of the first block species, and a volume fraction, F2A, of the second block species is formed. A material having a predefined morphology where the sum of F2A and F3 were preselected is formed.

  • Publication number: 20070117040
    Abstract: A topcoat material for applying on top of a photoresist material is disclosed. The topcoat material comprises a polymer which is sparingly soluble or insoluble in water at a temperature of about 25° C. or below but soluble in water at a temperature of about 60° C. or above. The polymer contains poly vinyl alcohol monomer unit and a poly vinyl acetate or poly vinyl ether monomer unit having the following polymer structure: wherein R is an aliphatic or alicyclic radical; m and n are independently integers, and are the same or different; and p is zero or 1. The topcoat material may be used in lithography processes, wherein the topcoat material is applied on a photoresist layer. The topcoat material is particularly useful in immersion lithography techniques using water as the imaging medium. The topcoat material of the present invention are also useful for immersion lithography employing organic liquid as immersion medium.

  • Publication number: 20060241194
    Abstract: Substantially or roughly spherical micellar structures useful in the formation of nanoporous materials by templating are disclosed. A roughly spherical micellar structure is formed by organization of one or more spatially unsymmetric organic amphiphilic molecules. Each of those molecules comprises a branched moiety and a second moiety. The branched moiety can form part of either the core or the surface of the spherical micellar structure, depending on the polarity of the environment. The roughly spherical micellar structures form in a thermosetting polymer matrix. They are employed in a templating process whereby the amphiphilic molecules are dispersed in the polymer matrix, the matrix is cured, and the porogens are then removed, leaving nanoscale pores.

  • Publication number: 20060240240
    Abstract: A nanoporous material exhibiting a lamellar structure is disclosed. The material comprises three or more substantially parallel sheets of an organosilicate material, separated by highly porous spacer regions. The distance between the centers of the sheets lies between 1 nm and 50 nm. The highly porous spacer regions may be substantially free of condensed material. For the manufacture of such materials, a process is disclosed in which matrix non-amphiphilic polymeric material and templating polymeric material are dispersed in a solvent, where the templating polymeric material includes a polymeric amphiphilic material. The solvent with the polymeric materials is distributed onto a substrate. Organization is induced in the templating polymeric material. The solvent is removed, leaving the polymeric materials in place. The matrix polymeric material is cured, forming a lamellar structure.

  • Patent number: 5852250
    Abstract: A collapsible instrument stand for suspending an elongate instrument in a vertical orientation. The instrument stand generally includes three basic members: a base member which supports the stand, a head member from which an instrument is suspended, and a first member which rigidly supports the head member. The base and head members are preferably attached to respective ends of the first member in a pivotable manner. When configured for use, the base and head members are folded out to be generally orthogonal to the first member. When configured for storage and/or transportation, the base and head members are folded to become flush with, and generally be collateral and/or coplanar with the first member. In the latter configuration, the instrument stand can be stored within a flat outer compartment of an instrument case, if not within the instrument case itself.
