Abstract: Systems, methods and apparatuses are provided for the measurement of intraocular pressure. These systems, methods and apparatuses can include an imaging apparatus for capturing two- or three-dimensional images or video of a patient's eye. An image reconstruction based on the captured images or video can be performed, and measurements can be taken of blood vessel features, curvature metrics, or distances between point pairs. In some embodiments, blood pressure measurements can also be taken synchronously with the captured images or video. From these measurements, a relationship between certain medical condition (e.g., elevated intraocular pressure, heart arrhythmia) and the extracted metrics can be established.

Abstract: Systems, methods and apparatuses are provided for the reduction of hydrodynamic frictional drag. These systems, methods and apparatuses can include a vessel surface having an external layer and a plurality of dimples, wherein the external layer comprises a hydrophilic material, and wherein each of the dimples includes an inner surface having a superhydrophobic coating. The dimples can be configured to maintain an air-water interface as one or more fluids flow over the vessel surface. In some embodiments, a pressure reservoir can be coupled with the dimples, and can include an acoustic speaker to vibrate the air-water interface.

Abstract: Hardware and software methodology are described for three-dimensional imaging in connection with a single sensor. A plurality of images is captured at different degrees of focus without focus change of an objective lens between such images. Depth information is extracted by comparing image blur between the images captured on the single sensor.

Abstract: A network of high-resolution cameras for monitoring and controlling a drone within a specific operational environment such that the latency time for communication between the cameras and drone is less than that of human controlled drones. The drone can communication drone health data to the network of cameras where such information can be combined with visual image data of the drone to determine the appropriate flight path of the drone within the operational environment. The drone can then subsequently be controlled by the network of cameras by maintaining a constant visual image and flight control data of the drone as it operates within the environment.

Abstract: The subject system hardware and methodology combine disparate cameras into a cohesive gesture recognition environment. To render an intended computer, gaming, display, etc. control function, two or more cameras with non-coaxial axes are trained on a space to detect and lock onto an object image regardless of its depth coordinate. Each camera captures one 2D view of the gesture and the plurality of 2D gestures are combined to infer the 3D input.
Abstract translation: 主题系统硬件和方法将不同的相机组合成一个凝聚的手势识别环境。 为了呈现预期的计算机，游戏，显示等控制功能，在空间上训练具有非同轴轴的两个或更多个相机以检测和锁定到对象图像上，而不管其深度坐标如何。 每个摄像机拍摄手势的一个2D视图，并且组合多个2D手势以推断3D输入。
