Abstract:
According to various embodiments, a method for manufacturing a lens may be provided. The method may include: determining a NURBS (non-uniform rational basis spline) representation of a provisional lens geometry; simulating ray trajectories in a lens with the provisional lens geometry based on the NURBS representation; determining a final lens geometry based on the simulated ray trajectories; and producing a lens with the final lens geometry.
Abstract:
Stream-switching techniques are applied in a content delivery system. A merge frame is generated as a function of bit-rates, distortion, and a piecewise constant operator. Parameters of the piecewise constant operator are selected to optimize the merge frame. Data streams are switched based on bandwidth requirements, switch requests, and throughput of a network. Images are reconstructed based on the merge frames and prediction frames. Reconstructed images are identically reconstructed for any prediction frame based on the merge frame.
Abstract:
Disclosed herein is are systems, devices, and methods for an autorotating aerial device which includes a housing member having disposed thereon an actuator and a controller configured to control the actuator. The device also includes a wing member coupled to the actuator, the wing member including a main wing portion and a flap portion adjustable with respect to the main wing portion. The controller is configured to control the actuator to switch the autorotating aerial device between a diving mode of operation and an autorotating mode of operation based on adjusting an angle of attack of the flap portion, the angle of attack being with respect to a lateral axis along the main wing portion.
Abstract:
A carbon capture device is described. The carbon capture device comprises a carbon capture film for capturing carbon dioxide; and an exposure mechanism for exposing a portion of the carbon capture film to a surrounding environment for capturing carbon dioxide. The exposure mechanism comprises a receiver for receiving an exposed portion of the carbon capture film and a storage for holding an unexposed portion of the carbon capture film, wherein the receiver is adapted to be connected to a portion of a leading end of the carbon capture film and to convey the unexposed portion of the carbon capture film from the storage to the receiver for exposing the portion of the carbon capture film to the surrounding environment. A method of using the carbon capture device for carbon capture is also described.
