摘要： An opto-acoustic transducer may include a light source, a substrate, a top layer, an interstitial layer, a lens, and a detector array. The light source may generate light beams. The substrate may reflect the light beams generated by the light source. The top layer may modulate responsive to an acoustical wave impingent thereupon and may reflect the light beams generated by the light source. The interstitial layer may be between the substrate and the top layer and may include a cavity which acts as an optical collector. The lens may propagate the light beams reflected by the substrate and the light beams reflected by the top layer. The detector array may reconstruct the acoustical wave impingent on the top layer based on the light beams propagated by the lens.

摘要： A variable pitch propeller is designed to adjust the pitch of the propeller blade during flight to maximize the propeller efficiency. The propeller blade may comprise airfoil cross-sections. Each cross-section may be composed of different materials at the leading edge and trailing edge. In various embodiments, these materials are selected and oriented to achieve the necessary elastic moduli of the leading and trailing edge for the airfoil cross-section. During liftoff, the airfoil at the blade tip possesses a high blade pitch (e.g. 20 degrees), thereby increasing the generated lift on the propeller blades. During flight or hover conditions when maximal lift is no longer required, the trailing edge of the airfoil displaces upward and reduces the blade pitch to minimize the drag forces on the blade tip.

摘要： Disclosed is an electronically controlled camera iris device. The camera iris device may include a transparent conductor layer supplying an input voltage controlling the diameter of the aperture, a transparent resistance layer providing different voltages in different regions varying based on the distance from a center point, and a diaphragm layer that can be independently controlled in different regions to block or transmit light incident on the diaphragm layer when corresponding control voltages are applied on the diaphragm layer. The camera iris device can be configured to have a desired diameter by controlling a first region of the diaphragm layer to transmit the light and a second region of the diaphragm layer outside of the first region to block the light. The diaphragm layer may include a Bragg grating layer or an Electrochromic layer.

摘要： A propeller blade includes a first material and a second material. The first material includes fibers. The second material is different from the first material. The fibers are interspersed through the second material and the fibers are oriented in a same direction within the second material. The propeller blade is anisotropic and includes sections of the fibers.

摘要： A visualization device allows a user to be immersed in visual content by projecting the visual content to the user. A projection element is positioned such that visual content projected from the projection element is reflected off of a mirror, which is angled such that the reflected projection is reflected onto a lens doublet. The lens doublet is angled such that the visual content projection reflected onto the lens doublet is partially reflected toward the user. In addition, an electrochromic slab can be controlled to allow configurable amounts of ambient light into the visualization device. If the electrochromic slab is configured such that no ambient light is allowed into the visualization device, the user is only able to see the visual content projected by the display device. The electrochromic slab can also be configured to allow some or all ambient light to travel into the visualization device.

摘要： A positioning system is designed to align a lens barrel with a sensor assembly. A first end of a lens barrel includes ridges along an edge. The sensor assembly includes a recessed channel with reciprocal ridges for mating with the ridges of the lens barrel. The sensor assembly also includes a plurality of shim platforms structured, each structured to position a wedge shaped shim, the wedge shaped shim including a flat bottom to slide on the shim platform and raise or lower the lens barrel relative to the reciprocal ridges on which the lens barrel rests.
