Linear accelerator accelerating module to suppress back-acceleration of field-emitted particles
A method for the suppression of upstream-directed field emission in RF accelerators. The method is not restricted to a certain number of cavity cells, but requires similar operating field levels in all cavities to efficiently annihilate the once accumulated energy.

The method enables a significant energy reduction for upstream-directed electrons within a relatively short distance. As a result of the suppression of upstream-directed field emission, electrons will impact surfaces at rather low energies leading to reduction of dark current and less issues with heating and damage of accelerator components as well as radiation levels including neutron generation and thus radio-activation. |

The path loss and the current D2D transmission power level are used to estimate the amount of interference the base station is experiencing as a result of the D2D transmissions from the wireless device. Based on the estimated interference experienced by the base station, the wireless device increases the robustness of the MCS being used and decreases the transmission power level by a corresponding amount. By decreasing the D2D transmission power level, less interference will be experienced by the base station. By increasing the robustness of the MCS, the impact of the reduced D2D transmission power level is mitigated. |

Reducing retrieval times for compressed objects
An intermediary system reduces a delay associated with the compression and transmission of content resources to a user's device. For example, the intermediary system compresses a first content resource, generates a signature of the first content resource, stores the compressed first content resource and the generated signature, and transmits the compressed first content resource to the user's device. When the user's device or another user's device requests a second content resource at a later time, the intermediary system generates a signature of the second content resource and compares it with the signature of the first content resource. If the signatures match (meaning the first and second content resources are very likely identical), then the intermediary system merely transmits the compressed first content resource to the appropriate device instead of first compressing the second content resource and then transmitting the compressed second content resource to the appropriate device. |

Fast encoding of live streaming media content
Techniques and mechanisms described herein facilitate the management of encoders for live media content streams. A media content system may employ potentially many encoders to encode potentially many live media content streams. When supporting many live media content streams, there may be some channels that are not being viewed by anyone at a particular time. In some such situations, an encoder encoding a live media content stream that is not being viewed may be disabled. Then, live media content associated with the live media content stream may be stored in a buffer and updated as new live media content is received. When a user transmits a request to view a channel for which the encoder has been disabled, an encoder for the requested channel may be enabled. The buffered data may be used to quickly initialize the encoder. |

In general, techniques are described in which packet replicators of a network device cooperate to generate a distributed hierarchical forwarding structure that the packet replicators then use to replicate and forward multicast packets to multiple output interfaces.

Each child PFE determines from the hierarchical forwarding structure the identity of a parent PFE and issues a token, constituting forwarding state for the distributed hierarchical forwarding structure, to the parent PFE. The parent PFE uses the token to identify packets of the multicast traffic to the child PFE during replication and forwarding of multicast packets proceeding according to the hierarchical forwarding structure. |

Channelized active noise elimination (CANE) for bit stream RF transmitters
A band pass filter is implemented utilizing Channelized Active Noise Elimination (CANE) in combining Finite Impulse Response (FIR) filtering into a radio frequency (RF) transmitter, or transmission path. The FIR filtering is performed in a combination of multiple conversion paths of delay units, vector modulators and PAs so that the low pass characteristics of the FIR filter are upconverted on the adjacent frequency of the carrier to form a band pass filter at the output of the transmitter. Use of CANE avoids the need of high sampling rates, while also eliminating the need of either broad bandwidth delay lines or modulated power amplifiers. The technique is well-suited for suppression of the quantization noise generated in RF transmitters with bitstream modulations such as the Envelope Delta Sigma Modulation (EDSM). |

Dither injection for continuous-time MASH ADCS
For continuous-time multi-stage noise shaping analog to digital converters (CT MASH ADCs), quantization noise cancellation often requires estimation of transfer functions, e.g., a noise transfer function of the front end modulator. To estimate the noise transfer function, a dither signal can be injected in the front end modulator. However, it is not trivial how the dither signal can be injected, since the dither signal can potentially leak to the back end modulator and cause overall noise degradation. To address some of these issues, the dither signal is injected post the flash analog to digital converter (ADC) of the front end modulator. Furthermore, dummy comparator structures can be used to synchronize the dither with the quantization noise of the targeted flash ADC. |

Optical phase-sensitive amplifier with raman amplifier intermediate stage
A method and system for amplifying optical signals includes generating idler signals for input signals using an optical pump at a first non-linear element (NLE). An intermediate stage including a Raman amplifier performs pump amplification using the output from the first NLE along a single optical path. Optical power monitoring of the input signals may be used for power equalization. The intermediate stage may include a wavelength selective switch for a certain degree of phase modulation. The phase-sensitive amplified signal is generated at a second NLE using the optical pump. Optical power monitoring of the input signals may be used for power equalization and other control functions to achieve low-noise operation. |

Connector
An electrical connector having a highly reliable electric shock prevention mechanism.The electrical connector has a housing, tab terminals, and a slidable member. The slidable member has engagement arms. The engagement arms have on forward sides fixed ends joined to a front side wall extending forward from an abutting wall, extend rearward in the form of cantilevers, and have hook portions. The hook portions engage with a mating electrical connector and this engagement causes the hook portions to be pulled by the mating electrical connector when the mating electrical connector in a mating state is extracted, so that the slidable member slides to a forward position. In addition, the housing is provided with anti-deflection walls. The anti-deflection walls allow the engagement arms to deflect so that the mating electrical connector can climb over the hook portions when the slidable member is located in the forward position. In addition, these anti-deflection walls prevent the engagement arms from deflecting when the slidable member is located near a rearward position rather than the forward position. |
