The device includes a processor, memory, a network interface, and a jitter buffer implemented in the memory. The jitter buffer buffers programming content and control messages, which are received from a source location of the decentralized media playout system, before transmitting them to a mixer. A first relative timing relationship between the programming content and the control messages exists at the source location, and a second, altered relative timing relationship between the programming content and the control messages exists at the destination location. The processor restores the first relative timing relationship between the programming content and the control messages, as it existed at the source location, by instructing the jitter buffer to delay transmitting either the programming content or the control messages to the mixer. |

Characterizing user behavior in a computer system by automated learning of intention embedded in a system-generated event graph
An automated technique for security monitoring leverages a labeled semi-directed temporal graph derived from system-generated events. The temporal graph is mined to derive process-centric subgraphs, with each subgraph consisting of events related to a process. The subgraphs are then processed to identify atomic operations shared by the processes, wherein an atomic operation comprises a sequence of system-generated events that provide an objective context of interest. The temporal graph is then reconstructed by substituting the identified atomic operations derived from the subgraphs for the edges in the original temporal graph, thereby generating a reconstructed temporal graph. Using graph embedding, the reconstructed graph is converted into a representation suitable for further machine learning, e.g., using a deep neural network. The network is then trained to learn the intention underlying the temporal graph. The approach operates to understand running behavior of programs, to classify them, and then enable detection of potential malicious behaviors. |

Systems and methods for ultra wideband impulse radio protocols
Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Today's leading edge modulated sinusoidal wave wireless communication standards and systems achieve power efficiencies of 50 nJ/bit employing narrowband signaling schemes and traditional RF transceiver architectures. However, such designs severely limit the achievable energy efficiency, especially at lower data rates such as below 1 Mbps. Further, it is important that peak power consumption is supportable by common battery or energy harvesting technologies and long term power consumption neither leads to limited battery lifetimes or an inability for alternate energy sources to sustain them. Accordingly, it would be beneficial for next generation applications to exploit inventive transceiver structures and communication schemes in order to achieve the sub nJ per bit energy efficiencies required by next generation applications. |

Table-top ultra supercontinuum and higher harmonic generation source for microscopy
In this patent, we teach methods to generate coherent X-ray and UUV rays beams for X ray and UUV microscopes using intense femtosecond pulses resulting the Ultra-Supercontinuum (USC) and Higher Harmonic Generation (HHG) from χ3 and χ5 media produce from electronic and molecular Kerr effect. The response of n2 (χ3) and n4 (χ5) at the optical frequency from instantaneously response of carrier phase of envelope results in odd HHG and spectral broadening about each harmonic on the anti-Stokes side of the pump pulse at wo typically in the visible, NIR, and MIR. From the slower molecular Kerr response on femtosecond to picosecond from orientation and molecular motion on n2 and n4 which follow the envelope of optical field of the laser gives rise to extreme broadening without HHG. The resulting spectra extend on the Stokes side towards the IR, RF to DC covering most of the electromagnetic spectrum. These HHG and Super broadening covering UUV to X rays and possibly to gamma ray regime for microscopes. |

High speed, high density direct mate orthogonal connector
A direct mate orthogonal connector for a high density of high speed signals. The connector may include right angle leadframe assemblies with signal conductive elements and ground shields held by a leadframe housing. High frequency performance may be achieved with members on the leadframe that transfer force between a connector housing, holding the leadframe assemblies, and a portion of the leadframe housing holding the signal conductive elements and the shields near their mounting ends. Core members may be inserted into the housing and mating ends of the conductive elements of ground shields may be adjacent the core members, enabling electrical and mechanical performance of the mating interface to be defined by the core members. The core members may incorporate insulative and lossy features that may be complex to form as part of the connector housing but may be readily formed as part of a separate core member. |

Connection between a reinforced harness and an electrical component
A connection includes a widened reinforcement harness which comprises a reinforced harness, a non-deformable ferrule and a reinforcement portion which has a greater diameter than the reinforcement of the harness, the non-deformable ferrule being arranged around the harness with the reinforcement of the harness folded on the outer side of the non-deformable ferrule, a first end of the reinforcement portion being attached around the folded portion of the reinforcement of the harness, the connection further comprising an integrated coupling connector, a second end of the reinforcement portion of the widened reinforcement harness being attached to a section of the integrated coupling connector. This connection is particularly advantageous for the small harness, wherein the reinforcement of the harness has a diameter which is too small to surround the section of an integrated coupling connector. |

Cavity filter and connecting structure included therein
The present invention relates to a cavity filter including: an RF signal connecting portion spaced apart, by a predetermined distance, from an outer member having an electrode pad provided on a surface thereof; and a terminal portion configured to electrically connect the electrode pad of the outer member and the RF signal connecting portion so as to absorb assembly tolerance existing at the predetermined distance and to prevent disconnection of the electric flow between the electrode pad and the RF signal connecting portion, wherein a part of the terminal portion, positioned between the electrode pad and the RF signal connecting portion, is elastically deformed to absorb assembly tolerance existing in a terminal insertion port. Therefore, the cavity filter can efficiently absorb assembly tolerance which occurs through assembly design, and prevent disconnection of an electric flow, thereby preventing degradation in performance of an antenna device. |

Miniaturized electrical connector for compact electronic system
The present disclosure provides an electrical connector. The electrical connector comprises an insulative housing and a plurality of terminals disposed in the insulative housing. The insulative housing comprises a top face, a bottom face opposite to the top face, and a plurality of side faces extending between the top face and the bottom face. A corner portion between at least two adjacent side faces of the side faces is formed as a chamfered surface. Such a configuration reduces the dimension of the electrical connector, enables a more compact arrangement of components on the electronic system, and enables the dimension of the electronic system to be reduced, such that the entire assembly, including the electrical connector and the electronic system, can be manufactured at a lower cost and can be more compact and more lightweight. |

Circuit for optoelectronic down-conversion of THz signals
A circuit for optoelectronic down-conversion of a terahertz, THz, signal comprises a first photodiode and a second photodiode configured to be excited by an optical beat signal. The photodiodes are coupled in series through a common antenna. The terminals of the antenna are coupled to form an output terminal and the antenna is configured to receive the terahertz, THz, signal. The photodiodes thereby, via the optical beat signal, respectively, down-convert the THz signal and generate a current comprising an intermediate frequency, IF, component and a direct current, DC, component. The respective generated currents are summed at the output terminal, thereby obtaining the IF components and cancelling the DC components. |
