Background: The 3D laser scanner is a non-contact active-sensing system, which has a number of applications. Many patents have been filed on the technologies for calibrating 3D laser scanner. A precise calibration method is important for measuring the accuracy of the 3D laser scanner. The system model contains three categories of parameters to be calibrated which include the camera intrinsic parameters, distortion co Read More

Background: In the interest of improving aircraft performance, studies have highlighted the benefits of Box wing configurations over conventional cantilever aircraft configuration. Generally, the greater an aircraft's average thickness to chord ratio (Τ), the lower the structural weight as well as volumetric capacity for fuel. On the other hand, the lower the (Τ), the greater the drag reduction. A review of patents related to the Box Read More

Background: Flexible needle insertion is one of the minimally invasive surgeries, which takes advantage of the lateral force acted on the bevel tip to make the needle shaft bend when inserted into the tissue. The bending makes the needle avoid the obstacles (like bones, veins, nerves, etc.) in order to reach the target. However, the traditional flexible needle neither can change its curvature of the path, nor can realize a precise Read More

Background: Energy consumption in mechanical apparatus has become a big problem in modern industry. It is very important to develop energy-conserved rotary machines, which are very promising in the future. Objective: To introduce a patented energy-conserved hydrodynamic journal bearing with low friction where the interfacial slippage is designed on the whole sleeve surface. Methods: The analytical results are pres Read More

Background: Induced drag accounts for significant percentage of cruise and total aircraft drag. In agreement with Prandtl’s theorem, the ideal arrangement for minimum induced drag is a closed biplane design. Past studies have implemented fixed tip fins for closed biplane design, with the reduction of induced drag associated with fixed tip fin found to be less than optimal. A review of patents related to the box-wing aircraft Read More
