Frequency management methods and communication networks utilizing such frequency management methods are disclosed. More specifically, multiple frequency sets may be utilized to facilitate frequency hopping and a frequency management method may implement various switching schemes to switch between the different frequency sets. Techniques such as synchronization and spectrum harvesting may also be provided to support utilization of multiple frequency sets, all of which may provide improved operation reliabilities and better handling of jamming signals.

An optical waveguide comprises at least two TIR surface and contains a grating. Input TIR light with a first angular range along a first propagation direction undergoes at least two diffractions at the grating. Each diffraction directs light into a unique TIR angular range along a second propagation direction.

A method includes determining that a first receiver of a node N1, N2, N7 or N11 of a mobile ad-hoc network (MANET) is in an electromagnetic contested environment for a first frequency. The method also includes scanning a frequency coverage range of a second receiver of the node for unused frequencies. The method additionally includes selecting a frequency from the unused frequencies, the selected frequency to be used for communication of messages from another node N5 or N6 of the MANET to the node via the second receiver. The method further includes transmitting, to the other node N5 or N6, a message including information of the selected frequency via the transmitter. In embodiments where there are multiple jammed nodes, e.g., nodes N1, N2, N7, and N11, frequency selection enhancements (e.g., optimizations) to improve network functionality are possible. For example, jammed nodes N1, N2, N7, and N11 may each select different unused frequencies, Fx1, Fx2, Fx3, Fx4, for example, if each jammed node selects a different frequency from the free frequencies (e.g., detected by the second auxiliary receiver scanning output) list. The use of four different frequencies by the nodes N1, N2, N7, and N11 would force the jammer to spread its energy over more frequencies, thereby reducing the impact of the jammer on the network. A node can utilize performance statistics, such as number of successful bursts received, cyclic redundancy check (CRC) failures, acquisition failures, slot error rate, packet error rate, to determine whether the node is being jammed. Each node may include an chip scale atomic clock to maintain time synchronization over significantly longer periods:

Systems and methods for improving rendering performance of graphics processors are disclosed. A graphics processor may be configured to maintain access to multiple framebuffer sets stored in a non-transitory processor-readable medium. Two or more framebuffer sets may be configured to support different numbers of samples per pixel. The graphics processor may be further configured to determine whether a performance metric of a first frame processed using a first framebuffer set exceeded a threshold. The graphics processor may select a second framebuffer set with a reduced number of samples per pixel compared to the first framebuffer set when the performance metric of the first frame exceeded the threshold and process a second frame for display to a viewer utilizing the second framebuffer set.

Signal acquisition methods and receivers utilizing such signal acquisition methods are disclosed. More specifically, a signal acquisition method may include: identifying a list of available beam patterns that an antenna unit is configured to provide; iteratively searching for satellite signals by controlling the antenna unit to utilize one of the list of available beam patterns in each iteration; determining whether a satellite signal is detected in each iteration; collecting ephemeris data of a satellite producing the satellite signal when the satellite signal is detected in each iteration; and controlling beamforming operations of the antenna unit for satellite signal acquisition based on the ephemeris data collected.

Methods performed by an optoelectronic system are disclosed. A first method may be performed by a pulse data generator configured to acquire time from a clock; determine pulse data representative of a sequence of duration times and/or wavelength ranges as a function of, in part, a wavelength hopping algorithm; and determine and generate an output for controlling an operation of at least one optoelectronic system. A second method may be performed by a sensor controller configured to acquire the pulse data; and generate an output for controlling an operation of an optoelectronic system employed to produce an image viewable to a viewer. A third method may be performed by an image generator configured to acquire the pulse data; acquire digital data from an optoelectronic system; and generate image data representative of an image represented in data acquired from the optoelectronic system as a function of the pulse data.

A weather radar control system includes a processor configured to acquire first weather data for a first area extending from an aircraft from a weather radar system onboard the aircraft. The first weather data includes a first location of a weather event in the first area. The processor is further configured to receive second weather data for a second area with respect to the aircraft via the communication system from an external location where the second weather data includes a second location of a weather event in the second area, and correlate the first weather data and the second weather data. The processor is further configured to generate display data for display based on the correlated weather data where the display data is for a display area at least partially defined by the first and second areas, and provide the display data to a display system onboard the aircraft.

A combined pulsed and FMCW AESA radar system is described. The radar system includes an AESA array of radiating elements, an array of TR modules, an RF combiner/splitter, a transmitter, a pulsed radar receiver and an FMCW radar receiver. Each TR module corresponds to a respective radiating element of the array of radiating elements. The transmitter is configured to transmit an excitation signal to excite selected or all radiating elements of the array of radiating elements via the TR modules. When the transmitter is in a pulsed radar mode, the pulsed radar receiver is configured to receive radar return signals via the RF combiner/splitter from radiating elements of the array of radiating elements via the TR modules. When the transmitter is in an FMCW radar mode, the FMCW radar receiver is configured to receive radar return signals from selected radiating elements of the array of radiating elements via the TR modules.

Embedded systems are the key innovation driver to improve almost all mechatronic products with cheaper and even new functionalities. Furthermore, they strongly support todays information society as inter-system communication enabler. Consequently boundaries of application domains are alleviated and ad-hoc connections and interoperability play an increasing role. At the same time, multi-core and many-core computing platforms are becoming available on the market and provide a breakthrough for system (and application) integration. A major industrial challenge arises facing (cost) efficient integration of different applications with different levels of safety and security on a single computing platform in an open context. The objective of the EMC project (Embedded multi-core systems for mixed criticality applications in dynamic and changeable real-time environments) is to foster these changes through an innovative and sustainable service-oriented architecture approach for mixed criticality applications in dynamic and changeable real-time environments. The EMC2 project focuses on the industrialization of European research outcomes and builds on the results of previous ARTEMIS, European and National projects. It provides the paradigm shift to a new and sustainable system architecture which is suitable to handle open dynamic systems. EMC is part of the European Embedded Systems industry strategy to maintain its leading edge position by providing solutions for: . Dynamic Adaptability in Open Systems . Utilization of expensive system features only as Service-on-Demand in order to reduce the overall system cost. . Handling of mixed criticality applications under real-time conditions . Scalability and utmost flexibility . Full scale deployment and management of integrated tool chains, through the entire lifecycle Approved by ARTEMIS-JU on 12/12/2013 for EoN. Minor mistakes and typos corrected by the Coordinator, finally approved by ARTEMIS-JU on 24/01/2014. Amendment 1 changes approved by ECSEL-JU on 31/03/2015.
