摘要： A rotary steerable apparatus is provided having an actuator for pushing the bit or pointing the bit that includes a shape memory alloy. An elongated form of the alloy, such as a wire or rod, is employed in a mechanism that applies force in a direction transverse to the wellbore in response to a change in length of the alloy. Temperature of the alloy is controlled to change shape and produce the desired force on pads for operating the apparatus. The apparatus may be used with downhole power generation and control electronics to steer a bit, either in response to signals from the surface or from downhole instruments.

摘要： The proposed adaptive exhaust nozzle features an innovative use of the shape memory alloy (SMA) actuators for actively control of the opening area of the exhaust nozzle for jet engines. The SMA actuators remotely control the opening area of the exhaust nozzle through a set of mechanism. An important advantage of using SMA actuators is the reduction of weight of the actuator system for variable area exhaust nozzle. Another advantage is that the SMA actuator can be activated using the heat from the exhaust and eliminate the need of other energy source. A prototype has been designed and fabricated. The functionality of the proposed SMA actuated adaptive exhaust nozzle is verified in the open-loop tests.

摘要： A method for inspecting an edible oil includes obtaining a first Raman spectrum from an edible oil sample, discovering an unhealthy, unsanitary, unsafe, or adulterated content in the edible oil sample in part by the intensity level of the fluorescence background in the first Raman spectrum, introducing the edible oil sample to nano-scale surface structures to allow molecules of the edible oil sample to be adsorbed to the nano-scale surface structures, illuminating the edible oil sample and the nano-scale surface structures by a laser beam, obtaining a second Raman spectrum from light scattered by molecules of the edible oil sample adsorbed to the nano-scale surface structures, and identifying the unhealthy, unsanitary, or unsafe content in the edible oil sample using one or more first spectral signatures in the second Raman spectrum.

摘要： Systems and methods are disclosed for efficiently securing solar panels on a roof surface that does not require penetration of the roof membrane. Supports for the solar panels are designed with a small footprint with sufficient spacing to allow free drainage between the supports. A simple, low-cost attachment member or clip can be integrated with each support to attach the panel to the support, and in some instances the clip (or its mount on the support) can also be used to lift the support to the roof. The panels can include one or more rails that can slide through a loosened clip, but be held securely in place by a tightened clip. The panels can be installed initially with the clips grasping the rails loosely and once the supports and rails are in their final positions, the clips can be fully tightened to form a rigid solar panel array.

摘要： An aeroelastic solar-power-generating canopy is described that requires minimal construction efforts. The canopy can be formed over supporting structures such as columns, without requiring an existing roof. The canopy contains a plurality of solar panels arranged substantially adjacent to each other, which are coupled to attachment members. Linking members are coupled to the attachment members, the linking members providing a flexing point for the solar panels. A cable is coupled to the linking members, spanning a substantial portion of the distance covered by the solar panels, providing a restraining force. And, at least one of the attachment members and cable is coupled to a supporting structure, wherein the cable in conjunction with the linking members allows the solar panels to dynamically react to loads, the arranged solar panels operating as a covering and as a source of solar power.
