    摘要： A digital micromirror device arrangement and devices using the arrangement are disclosed. The arrangement includes a digital micromirror device (DMD) having an active area, a cover plate disposed substantially adjacent to the DMD and having a thickness and a light blocking area having an aperture formed therein. The active area is adapted to receive incoming light and to reflect the incoming light as outgoing light. The light-blocking layer is offset from a plane of the active area by at least the thickness of the cover plate and is adapted to block light from passing therethrough. The aperture is dimensioned to produce a beam of outgoing light having desired dimensions.

    摘要： An apparatus and a method are provided for the treatment of soft tissue. The apparatus includes a light source and at least two optical assemblies. Each of the optical assemblies includes at least one optical element and a light-transmitting contact surface configured to transmit a substantially uniform distribution of light therethrough. The apparatus further includes at least two optical transmission devices each disposed between the light source and a corresponding one of the at least two optical assemblies. The apparatus also includes a handpiece to which the at least two optical assemblies are attached, and which is adapted to bring the light-transmitting contact surfaces of the at least two optical assemblies in contact with soft tissue disposed therebetween. The method includes compressing and substantially flattening portions of the tonsil tissue between light-transmitting contact surfaces of two opposed light emitting optical assemblies, introducing light into an optical element of each of the optical assemblies; and irradiating the tonsil tissue by directing the light from the optical element through the light-transmitting contact surfaces to the tonsil tissue in a substantially uniform light distribution.

    摘要： A wind turbine blade includes a root region. A first extension (LEX) is attached to the leading edge side of the root region while a trailing edge strake (TES) is attached to the trailing edge side of the root region. The LEX and TES each include an outer profile that becomes more pronounced relative to their respective locations in the root region as the root region of the wind turbine blade morphs from a substantially cylindrical shape to a substantially airfoil shape. The LEX provides both optimal angle of attack and lift generation in the root region, while the TES mitigates airflow separation and enhances airfoil lift in the root region.

    摘要： A system and method for measuring pressure and flow rate of polymer slurry circulating in a loop reactor. For flow rate measurement, the loop reactor has a pressure tap on an outside radius of an elbow of the loop and a pressure tap on an inside radius of the elbow. The pressure taps incorporate diaphragms. Sensing legs couple the pressure taps with a differential pressure meter configured to provide a signal indicative of the flow rate of the polymer slurry. For pressure measurement, pressure taps without diaphragms at the loop reactor wall may be disposed at various points along the loop reactor, the pressure taps coupled to pressure sensing lines. A diluent flush line having a screen disposed therein may provide diluent to the pressure taps. The screen may reduce fouling of the pressure tap and sensing line with solids from the reactor.

    摘要： Disclosed herein are optical assemblies having thin, low profile shapes. These optical assemblies may be used with fiber coupled lasers and other light sources, including high power sources, to irradiate tissue at a wavelength suitable for inducing ablation or coagulation to a target depth, denaturation, thermal modification of a tissue, and/or preferential injury to a target tissue structure. Example optical assemblies can produce substantially uniform illumination patterns that are useful for treating superficial tissue, including the internal or luminal (e.g., esophageal) tissue. Some examples may have capability for cooling superficial tissue or skin, such as a detachable, reusable heat sink for active cooling without consumables, fluid pumps, or other cooling equipment.

    摘要： An airfoil includes a plasma actuation surface integrated onto the airfoil surface. On the airfoil, the plasma actuation surface is configured to provide high-frequency plasma actuation along the plasma actuation surface such that excitation of the vortex flow or shear flow mitigates the vortex flow or the shear flow associated with the airfoil.
