摘要:
A retractor having a housing having a handle portion at a first end and a blade portion at a second, opposite end. The retractor includes a light system having an organic light source for illuminating the blade portion. The light system is positioned within the housing such that it is fully encased by said housing. A pair of polarized light panels are attached to the blade portion for varying direction of light from the blade portion.
摘要:
Methods and apparatus are disclosed relating to graded-composition barrier coatings comprising first and second materials in first and second zones. The compositions of one or both zones vary substantially continuously across a thickness of the zone in order to achieve improved properties such as barrier, flexibility, adhesion, optics, thickness and tact time. The graded-composition barrier coatings find utility in preventing exposure of devices such as organic electro-luminescent devices (OLEDs) to reactive species found in the environment.
摘要:
A hybrid electroluminescent (EL) device comprises at least one inorganic diode element and at least one organic EL element that are electrically connected in series. The absolute value of the breakdown voltage of the inorganic diode element is greater than the absolute value of the maximum reverse bias voltage across the series. The inorganic diode element can be a power diode, a Schottky barrier diode, or a light-emitting diode.
摘要:
A method of forming an optical device comprising the steps of: providing a substrate comprising a first electrode capable of injecting or accepting charge carriers of a first type; forming over the first electrode a first layer that is at least partially insoluble in a solvent by depositing a first semiconducting material that is free of cross-linkable vinyl or ethynyl groups and is, at the time of deposition, soluble in the solvent; forming a second layer in contact with the first layer and comprising a second semiconducting material by depositing a second semiconducting material from a solution in the solvent; and forming over the second layer a second electrode capable of injecting or accepting charge carriers of a second type wherein the first layer is rendered at least partially insoluble by one or more of heat, vacuum and ambient drying treatment following deposition of the first semiconducting material.
摘要:
A light-emitting device comprises a stack of organic electroluminescent (EL) elements, wherein an organic EL element in the stack overlaps at least a portion of another organic EL element, and the organic EL elements are electrically separate. Each of the organic EL elements of the stack is activated with a different level of voltage.

摘要:
A silica deposition tube is fused in a deuterium (D2) gas atmosphere and optionally baked in a deuterium (D2) gas atmosphere to substantially reduce the hydrogen content in the tube for decreased fiber attenuation. Alternatively, raw silica material is pre-treated in D2 gas followed by fusing of the raw silica tube in a D2 gas environment.
