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:

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.

Alternating touchscreen conductors in each layer of a touchscreen display are connected to separate touchscreen controllers. Each controller completely and separately resolves a location anywhere on the display so that a failure of either controller, or the failure of conductors connected to either controller, do not degrade touchscreen usability. Conductors in separate layers, connected to separate controllers may be isolated via insulators to prevent undesirable shorts. Conductors are shaped to minimize the area covered by insulators and maximize the area of useful conductor overlap.

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.

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.

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.
