Methods and apparatus for transcoding digital video
Methods and apparatus for transcoding digital video data are disclosed. In an embodiment, a transcoder (300) decodes a digital video block (304) using a first coding scheme, such as 8×8 MPEG-2/4, to produce domain transformed data (306) and a motion vector (308).

For each sub-block with an estimated energy level below a desired threshold (e.g., likely an all-zero sub-block), the transcoder (300) transcodes the sub-block by converting the motion vector (308) from the first coding scheme (e.g., MPEG-2/4) to the second coding scheme (e.g., H.264) (e.g., convert 8×8 MPEG-2/4 vector to 4×4 H.264 vector or reuse the MPEG-2/4 vector if all four sub-blocks are AZB and coding in H.264 as an 8×8 block). The transcoded sub-block may then be used (e.g., stored or transmitted). |

Method for secure site and user authentication
The present invention provides a new method of site and user authentication. This is achieved by creating a pop-up window on the user's PC that is in communication with a security server, and where this communication channel is separate from the communication between the user's browser and whichever web site they are at. A legitimate web site embeds code in the web page which communicates to the security server from the user's desktop. The security server checks the legitimacy of the web site and then signals both the web page on the user's browser, as well as the pop-up window to which it has a separate channel. The security server also sends a random image to both the pop-up window and the browser. If user authentication is requested by the web site the user is first authenticated by the security server for instance by out of band authentication. Then the security server computes a one time password based on a secret it shares with the web site and sends it to the pop up window. The user copies this one time password into their browser which sends it to the web site, which can re-compute the one time password to authenticate the user. |

Box comprising a hinge device
A box comprising a box bottom part and a lid part which is pivotably supported relative thereto by means of a hinge device between an open and a closed position is particularly suited for use in the Ex area. The hinge device comprises a lower hinge part assigned to the box bottom part and an upper hinge part assigned to the lid part, which are pivotably connected to each other. To provide a permanent connection between lid part and box bottom part in a simple way and at low costs, while simultaneously said parts are pivotable relative to each other in a safe way, one hinge part is slidably supported and the other hinge part is arranged to be at least partly screw-mountable in the respectively assigned box bottom part and lid part, respectively. |

Touch-safe bus connection slider circuit breaker panel
A touch-safe bus connection device includes a bus extension (160, 260, 360), a non-conductive housing (110, 210, 310), a moveable electrical contact (150, 250, 350) and a moveable non-conductive cover (140, 240, 340). The contact is arranged in the housing, and is moved to connect or disconnect the extension and a stab of an electrical panel across a gap (192, 292, 392). The cover is concurrently and automatically moved to uncover or cover an opening (116, 216, 316) of the housing to allow or restrict, respectively, access to the extension. The contact and cover are concurrently and automatically moveable between a position at which the contact bridges the gap to connect the extension and the stab and the opening of the housing is covered by the cover, and another position at which the extension and the stab are disconnected across the gap and the opening of the housing is uncovered. |

Connector with sensor
A connector includes a housing that supports a core (which can be magnetic) and provides an inner channel. A power terminal is positioned in the inner channel and provides an electrical path between two opposite sides of the housing. The housing further support a sensor that is positioned in a gap in the core. The housing provides electrical isolation between the core and the power terminal. The connector can therefore provide both a power terminal and the ability to sense current in an integrated design. |

Connection module for field device in the explosion-proof area
The invention relates to a connection module for field devices in the explosion-protected area, having a housing with a plurality of controller-end terminals to connect to at least one input/output module and with field-end terminals to connect to the field devices. The connection module is characterized in that different resistors are present in the housing to provide intrinsically safe pairs of field-end terminals with different characteristic values, said resistors being hardwired in the housing to different field-end terminals and/or controller-end terminals. |

Stacked cage having different size ports
An electrical connector assembly includes a cage member having walls defining an upper port and a lower port configured to receive pluggable modules therein through a front end of the cage member. The cage member houses a communication connector at a rear of the cage member configured to be electrically connected to the pluggable modules received in the upper and lower ports. The walls are manufactured from a conductive material and providing electrical shielding for the pluggable modules. The plurality of walls include side walls, a top wall between the side walls, a bottom wall between the side walls and a divider wall between the side walls. The divider wall separates the upper port from the lower port. The divider wall is positioned closer to the top wall than the bottom wall such that the lower port is taller than the upper port. |
