    • An image display device includes an image processing unit, a light source assembly, an optical modulator assembly, and a projection lens assembly. The image processing unit is configured to receive a video signal and generate image data and control signals. The light source assembly and optical modulator assembly are each controlled by the control signals such that the light source assembly generates illumination in a spatial distribution pattern that is coupled to optical modular assembly via a homogenizing device. The projection lens assembly is configured to project an image from the optical modulator assembly onto a viewing surface. The optical modular assembly is configured to maximize the amount of illumination coupled from the light source assembly, and includes at least one optical modulator surface configured to have a substantially 1:1 aspect ratio.

    • Modular branch vessel stent-graft assemblies for the treatment arterial or vascular disease at the branch of two or more arteries or blood flow passageways, including, for example, abdominal aortic aneurysms are assembled in a patient's trunk/parent artery, from at least two components; a first component and a second component. The first and second components each include a first and second window, or fenestration. The second component couples with the first component by fitting at least partially in the first component to form the modular branch vessel stent-graft assembly with two selectively locatable branch openings. As the first and second components are deployed, the second component is selectively position able relative to first component so that the first and second component first and second windows overlap to form two branch openings whose longitudinal and angular positions are selectable within a range.

    • An efficient generator of electrical power employs groups of piezoelectric devices disposed in a radial manner about a centrally located cam. The cam, when rotated by a prime mover as a conventional source of mechanical energy, applies a periodic varying force to each piezoelectric device in a suitable sequence. The devices operate to respond to the rotation of the cam by having a cam follower coupled to each device via a spring, whereby a periodically varying force is applied to each piezoelectric device according to the cam surface and based on the rotation of the cam. Each device produces an output voltage according to the force applied to the device via the cam and the coupling between the device and the cam surface. Each device includes a stack of low loss piezoelectric plates connected together and responsive to the application of a mechanical stress to the stack to produce an electrical output.
    • 一种有效的电力发生器采用围绕中心定位的凸轮以径向方式设置的压电元件组。 当原动机作为常规的机械能源旋转时,凸轮以适当的顺序对每个压电装置施加周期性的变化的力。 这些装置通过具有经由弹簧联接到每个装置的凸轮从动件来响应于凸轮的旋转,由此根据凸轮表面并根据凸轮的旋转将周期性变化的力施加到每个压电装置。 每个装置根据通过凸轮施加到装置的力和装置与凸轮表面之间的联接产生输出电压。 每个装置包括连接在一起的低损耗压电板的堆叠,并且响应于将机械应力施加到堆叠以产生电输出。
