Abstract: Various examples are provided for flat lens antennas and their operation. In one example, among others, an antenna includes electrically thin (W<<?high), highly conducting, TEM mode antenna arms fed at a first end by a balun. The TEM mode antenna arms can be embedded in a spatially varied anisotropic dielectric material. A separation between the TEM mode antenna arms can increase from the first end to a second end where the TEM mode antenna arms transition to resistive card (Rcard) terminations when the TEM mode antenna arms are separated by a distance Hr, where a ratio of Hr to a height (H) of the antenna is in a range from about 0.2 to about 0.8.

Abstract: Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.

Abstract: Computerized systems and methods are disclosed, including a computer system that executes software that may receive a geographic location having one or more coordinates of a structure, receive a validation of the structure location, and generate unmanned aircraft information based on the one or more coordinates of the validated location. The unmanned aircraft information may include an offset from the walls of the structure to direct an unmanned aircraft to fly an autonomous flight path offset from the walls, and camera control information to direct a camera of the unmanned aircraft to capture images of the walls at a predetermined time interval while the unmanned aircraft is flying the flight path. The computer system may receive images of the walls captured by the camera while the unmanned aircraft is flying the autonomous flight path and generate a structure report based at least in part on the images.

Abstract: In one example, a system can receive an order from a client device. The system can also receive data about a set of print queues at a set of printers via a network. The system can then determine a set of queue times corresponding to the set of print queues. Each respective queue time can be determined based on a corresponding print queue. The system can generate an estimated wait time for the order based on the set of queue times. The system can then transmit the estimated wait time to the client device for display in a graphical user interface to a user associated with the order.

Abstract: A routing system and method for flows within a network provides multicast flow transport for one or more groups. Transit routers comprising processing units that run overlay processes route one or more flows based on overlay group identifiers. Access nodes issue requests for overlay groups in order to receive flows from the transit routers. The overlay processes utilize a mapping service that maps overlay group identifiers to native multicast group identifiers. A control channel between the access nodes and transit routers is used for communicating access nodes requests, overlay group identifiers, and native multicast group identifiers.

Abstract: As disclosed herein, a new and improved method and apparatus provide for fine tuning the position of a servomotor used to drive a transducer mounted on an ultrasound probe to a desired position. This improvement is accomplished by processing the analog quadrature output signals of an incremental optical encoder, coupled to the servomotor. The improvement uses the positional information derived from the analog quadrature output signals. The analog quadrature output signals, defined as sine and cosine, are converted to digital square waves. The digital square waves are decoded to produce digital position quadrants, wherein each quadrant represents a specific motor position. The corresponding digital square waves are also decoded by a logic array device and coupled to the select input of an analog switch.
