Abstract: A cathode ray tube has an electron gun oriented along an axis (Z), comprising a quadrupolar device which comprises three electrodes (5, 6, 7). Each electrode possesses a central aperture, a right lateral aperture and a left lateral aperture all three substantially rectangular. The centers (c5.1, c7.1) of the central apertures of the three electrodes are aligned along the axis (Z) of the gun. The centers (c6.1, c6.3) of the left and right lateral apertures of the second electrode (6) are situated along respectively a first axis (z1) and a second axis (z3) that are parallel to the axis (Z) of the gun. The centers (c5.1, c7.1) of the left and right lateral apertures (5.1, 5.3, 7.1, 7.3) of the first and/or of the third electrode (5,7) are offset with respect to the axes (z1, z3) passing through the centers of the apertures of the second electrode. Such an arrangement makes it possible to correct the MODEC defects.

Abstract: The invention proposes a repeater designed for indoor transmissions. The useful frequency band is split into two frequency bands and the repeater amplifies the signals from one of the bands and translates them to the other band. The transposition of frequency bands results in preventing creating significant interference effects on the signal to be amplified. A management circuit is used to address, at lower cost, interference problems between the bands.

Abstract: A scalable networking protocol that allows multiple nodes to communicate via a multi-channel network medium is described. The networking protocol allows any node on the network to assign itself as the active network server. The active network server polls client nodes based on a lineup card. The lineup card includes a high priority queue for low-latency devices, and a low priority queue for devices that can tolerate higher latencies. Network information is sent on the channels as fragments. The protocol provides bad-channel detection and retransmission of fragments in a fragment-by-fragment basis. Support for streaming data or asynchronous data is provided by allocating time slots on the network and allowing two intelligent nodes to talk directly to each other during count-limited token sessions, as arbitrated by the active network server.

Abstract: Cordless communication techniques for cordless communication devices having a handset unit and a base unit are provided. Such techniques can utilize a modulation method for Frequency Division Duplex/Time Division Duplex (FDD/TDD) that overcomes deficiencies of prior art devices, for example, by eliminating the need for a burst mode controller for both Frequency Division Duplex and Time Division Duplex, as well as surface acoustic wave bandpass filters and dielectric low pass filters.

Abstract: An electronic apparatus having a storage device received in a bracket, a printed circuit board on which the bracket is mounted, and a blower for cooling the storage device.

Abstract: A media area network includes a storage system having at least one storage device for storing digitized information. A host bus adapter provides a link between the storage system and a host system that provides overall control of the media area network. Within the host bus adapter, a lower-level port driver monitors communications between the storage system and the host bus adapter. In the event of a communications failure, the lower-level port driver initiates switching from a failed port to an alternative port, thereby achieving fail-over recovery. Allocating the responsibility for fail-over recovery to the lower-level port driver assures timely handling of port failures, thereby reducing potential latency delays.

According to the invention, the method comprises the steps of transforming the frequency and/or phase of harmonic deviations within the wobble signal to amplitude deviations, detecting the amplitude deviations, and detecting a current type of wobble period from the detected amplitude deviations.

Abstract: The local digital network comprises: access devices, for receiving data originating from outside the network and transmitting them at a point of the network; and presentation devices for receiving the data flowing in the network and presenting them at a point of the network. The data flow in the network in encrypted form and all the devices of the network use a single key, the local key of the network, for the encryption and decryption of the data. Preferably, the local key of the network is formed by a pair of public and private keys. The purpose of this network is to make it possible to copy data in the local network whilst preventing pirate copies destined for other local networks.

This device is intended to display a video image during a video frame comprising a plurality of consecutive subfields distributed within at least two separate identical time segments. According to the invention, the pixels of the video image change state at most once during each time segment and the video image to be displayed is saved in the image memory in the form of information identifying, for each subfield, the pixels changing state.

Abstract: A method for addressing cells in devices via an I2C bus is suggested, in which the common addressing scheme is supplemented by a ‘Data Transfer Mode’ byte. The ‘Data Transfer Mode’ byte specifies the number of the address and data bytes to follow the device addressing and thereby allows for orthogonal and scalable addressing of cells inside a device connected to the bus. The method is fully compatible to the existing I2C standard for writing to the slave device. Setting up and terminating a connection between a master and a slave as well as acknowledging receipt of a byte follows the standard.

The video production system provides an automation capability that allows the video director to pre-produce a show, review the show in advance of “air time,” and then, with a touch of a button, produce the live show. In one embodiment, the invention provides a video production system having a processing unit in communication with one or more of the video production devices mentioned above.

Abstract: The invention concerns a display apparatus with an imager illuminated by an illumination system and with an imaging system projecting an image on a viewing screen, wherein the brightness of the image on the imager has a variation over a given direction, and wherein the illumination system has light controlling elements for controlling the light distribution over the given direction.

Abstract: According to the invention sub-picture data are organized in sub-picture units, the sub-picture units comprising pixel data in a pixel data area as well as display control data and/or address information data, wherein a sub-picture unit of a second sub-picture stream is inserted into the pixel data area of a sub-picture unit of a first sub-picture stream. This permits several sub-picture streams for systems, which are defined to allow only a single sub-picture stream. Especially for DVD-VR conflicts with the already existing DVD-VR specification are avoided. Therefore, enhanced DVD-VR devices using the invention are able to record and playback additional sub-picture streams and conventional DVD-VR devices are able to record and playback the same signal without any compatibility problems, although restricted to only a single sub-picture stream.
