Printed circuit board cover
A sheet metal cover for a printed circuit board (PCB) includes a plurality of legs continuous with a substantially planar elevated section. The legs are attached to the PCB, and electrical connections are provided between the legs and an internal ground plane of the PCB at the attachment locations. The sheet metal cover is thereby grounded, inhibiting the transmission of electromagnetic signals through the sheet metal cover. The elevated section of the sheet metal cover prevents select electronic devices on the PCB from being viewed or probed. Openings through the sheet metal cover allow heat sinks or heat generating electronic devices (e.g., inductors) to be exposed through these openings, thereby facilitating cooling of these elements by airflow. An electrically conductive gasket attached to the underside of the elevated section may contact the heat sinks, further minimizing the radiation of EMI emissions. |

Controlling inter-cell interference in forward access channel (Cell—FACH) state
Since common E-DCH resources may be assigned from a single Node B, uplink macro-diversity may not be possible between neighboring Node B's.

Method and apparatus for transition encoding in video coding and decoding
The invention is related to video coding and decoding. More precisely, the present invention is dedicated to a coding method investigated in the scope of screen content coding, called palette mode. It particularly concerns the encoding of level values based on the use of patterns to predict the level value in order to avoid their transmission. It has been devised to avoid the transmission of level value when the value may be predicted based on the neighbourhood of the pixel to encode. This neighbourhood is matched against memorized pattern so as to predict the level value due to the repetitive occurrence of these patterns. It proposes to save a pattern table in addition to the palette table. This pattern table is constructed symmetrically by the encoder and the decoder and allows to retrieve some predicted level value and to avoid their transmission. |

Fractional redundant distribution of media content
A method and system for a client device to download media content directly from a group of other client devices which play a role of edge servers placed by a content service provider. According to some embodiments, an end user can use his/her client device to stream or download media content from the source client devices selected based on the geographic locality, network topology, etc. The fractions of data corresponding to a portion of media content are stored on the source client devices such that only a subset of the fractions of data are needed to recreate the corresponding portion. That is, by using the first received of the minimum number of fractions to reconstruct each portion of media content, the system does not need to wait for the slowest fractions to arrive, which contributes in reducing latency. |

Consciousness of environmental conservation is increasing nowadays, and there are power generators for a portable device and employing power generation schemes without a co2 discharge, such as solar power generation and hand-crank power generation. When, however, power is supplied, information indicating that the power is obtained from clean energy without a CO2 discharge is unknown at the portable-device side. When power is supplied from the power generator to the portable device, a power generation scheme identifier for identifying a power generation scheme is transmitted. The portable device identifies the power generation scheme identifier, and can recognize the power generation scheme of the connected power generator. A supplied power level is recognized based on a power level of the storage battery of the portable device at a time point of starting the power supply, and a power level of the storage battery at a time point of terminating the power supply. Since the power level in the storage battery is managed in this manner using the power generation scheme identifier, it becomes possible to determine whether or not the power generation scheme of the power in the storage battery is a clean scheme. |

Quick connect interface
A quick connect adaptor for conveying data or data and power from a first electronic unit to a second electronic unit. The adaptor includes a connectable interface between a first body part and a second body part, wherein the parts may be coupled with rotationally symmetry such that a 180 degree rotation of an adaptor body part, either clockwise or counterclockwise, results in an identical connection, eliminating the need for checking alignment when making a connection. A magnetic coupling secures the first and second body parts in either of two rotational orientations. In another embodiment, at least one end of the interface includes a “smart sensor” for detecting the magnetic polarity during the docking process and a processor or logic gates that configure communications so as to be correctly wired when coupled in either rotational orientation, even before an electrical connection is made. |

Electrical contact plug and plug housing
An electrical contact plug has a cable with a plurality of conductor cores connected thereto. A plug housing extends in the longitudinal direction and extends from a front contact region up to a rear insertion region. The cable is introduced into the plug housing in the rear insertion region and is surrounded by an injection-molded encapsulation. In order to avoid reliably the ingress of injection-molding compound into the front contact region during the injection-molding operation, the plug housing has a conical receptacle in the rear insertion region, with a cone element being formed as insert part in said conical receptacle, through which cone element the conductor cores are passed individually. Reliable and safe sealing of the conductor cores with respect to the contact region is performed via the cone element. |

High gain variable beam WI-FI antenna
This invention discloses a design and application of a variable beam antenna optimized for WI-HI application in data, video and voice transmission between various systems with an emphasis on medical monitoring. The subject antenna consists of a unique group of dipole radiators that are excited by zigzag feed lines and perform together as an array. This antenna is unique because it can provide various high gain beams by simply applying electrical shorts at the cross points in the feed lines. The shorts can be created mechanically or electronically. The antenna beam coverage can range from 15° to 110°- wide in H plane and maintains a constant beam width of 60° in E plane. The shorts are applied to reduce the antenna effective aperture, thereby increasing the beam width of the antenna. The current that flows to the outer dipoles are cut-off due to the shorts. |
